pertuzumab

Pertuzumab plus trastuzumab plus docetaxel for metastatic breast cancer. The anti-human epidermal growth factor receptor 2 (HER2) humanized monoclonal antibody trastuzumab improves the outcome in patients with HER2-positive metastatic breast cancer. However, most cases of advanced disease eventually progress. pertuzumab, an anti-HER2 humanized monoclonal antibody that inhibits receptor dimerization, has a mechanism of action that is complementary to that of trastuzumab, and combination therapy with the two antibodies has shown promising activity and an acceptable safety profile in phase 2 studies involving patients with HER2-positive breast cancer. ### methods We randomly assigned 808 patients with HER2-positive metastatic breast cancer to receive placebo plus trastuzumab plus docetaxel ( control group ) or pertuzumab plus trastuzumab plus docetaxel ( pertuzumab group ) as first-line treatment until the time of disease progression or the development of toxic effects that could not be effectively managed . The primary end point was independently assessed progression-free survival. Secondary end points included overall survival, progression-free survival as assessed by the investigator, the objective response rate, and safety. ### results The median progression-free survival was 12.4 months in the control group, as compared with 18.5 months in the pertuzumab group (hazard ratio for progression or death, 0.62; 95% confidence interval, 0.51 to 0.75; P<0.001). The interim analysis of overall survival showed a strong trend in favor of pertuzumab plus trastuzumab plus docetaxel. The safety profile was generally similar in the two groups, with no increase in left ventricular systolic dysfunction; the rates of febrile neutropenia and diarrhea of grade 3 or above were higher in the pertuzumab group than in the control group. ### conclusions The combination of pertuzumab plus trastuzumab plus docetaxel, as compared with placebo plus trastuzumab plus docetaxel, when used as first-line treatment for HER2-positive metastatic breast cancer, significantly prolonged progression-free survival, with no increase in cardiac toxic effects.

thiabendazole

aspirin

The effect of thiabendazole on pain threshold. thiabendazole significantly increased the reaction time to thermal stimulus. However, in mice treated with morphine, the reaction time was not in any way different from those treated with combined doses of thiabendazole and morphine. thiabendazole was found to have an antinociceptive action. The protective dose for 50% of animal (ED50) against p-benzoquinone-induced writhing reflex was found to be 310 mg/kg. The ED50 for aspirin alone was 140 mg/kg. When the ED50 of aspirin was determined in combination with different dose levels of thiabendazole, it showed a marked reduction in the values reaching 50 mg/kg, when 300 mg of thiabendazole was used in combination. Toxicological studies revealed that the oral LD50 for thiabendazole in mice was 2200 mg/kg , and when combined with 140 mg/kg of aspirin , the LD50 was reduced to 900 mg/kg . These findings indicate that thiabendazole possesses an analgesic activity which is potentiated by aspirin, though aspirin was found to significantly enhance its toxicity.


Azacitidine

enasidenib

Combination of azacitidine and enasidenib enhances leukemic cell differentiation and cooperatively hypomethylates DNA.  Azacitidine and enasidenib are two therapies available for treatment of acute myelogenous leukemia ( AML ) , and the mechanisms of action of these drugs involve alteration of aberrant DNA methylation . We hypothesized that a combination of these agents could have interactive effects on DNA methylation and enhance differentiation in mIDH2 cells. Combination treatment enhanced cellular differentiation in TF-1 cells overexpressing IDJ2R140Q through increased hemoglobinization and increased hemoglobin γ RNA expression compared with the effects of single agents. Furthermore, in primary AML samples (IDH2R140Q or R172K), combination treatment reduced CD34+ cells and increased CD15+ cells to a greater extent than attained with single agents. To explore the mechanism of enhanced differentiation with combination treatment, the TF-1 epigenome was analyzed by profiling 5-hydroxymethylcytosine (5hmC) and 5-methylcytosine (5mC) DNA methylation changes. enasidenib treatment alone increased 5hmC, consistent with reactivation of ten-eleven-translocation (TET) enzyme activity. Compared with treatment with azacitidine alone, combination treatment reduced 5mC levels at greater numbers of sites and these loci were significantly enriched in regions with increased 5hMC (25.8% vs. 7.4%). Results are consistent with a model in which enasidenib-mediated reactivation of ten-eleven-translocation enzymes cooperates with azacitidine-mediated inhibition of DNA methyltransferase enzymes, leading to greater reductions in DNA methylation and enhanced erythroid differentiation.


lamotrigine

amitriptyline

Randomized double-blind study comparing the efficacy and safety of lamotrigine and amitriptyline in painful diabetic neuropathy. To compare the efficacy and safety of lamotrigine and amitriptyline in controlling chronic painful peripheral neuropathy in diabetic patients. ### methods A randomized, double-blind, crossover, active-control, clinical trial with variable dose titration was carried out (n = 53). amitriptyline orally, at doses of 10, 25 and 50 mg at night-time, each dose for 2 weeks, and lamotrigine orally, at doses of 25, 50 and 100 mg twice daily, each dose for 2 weeks, by optional titration were used. There was a placebo washout period for 2 weeks between the two drugs. Assessment for pain relief, overall improvement and adverse events were carried out. ### results Good , moderate and mild pain relief were noted in 19 ( 41 % ) , six ( 13 % ) and seven ( 15 % ) patients on lamotrigine and 13 ( 28 % ) , five ( 11 % ) and 15 ( 33 % ) patients on amitriptyline , respectively , by patient 's global assessment of efficacy and safety . Patient and physicians global assessment, McGill pain questionnaire and Likert pain scale showed no significant difference between the treatments, although improvement with both treatments was seen from 2 weeks. Of the 44 adverse events reported, 33 (75%) were with amitriptyline, sedation being the commonest [in 19 (43%) patients]. lamotrigine caused adverse events in 11 (25%), of which rash in three (7%) and elevations of creatinine in four (9%) were the most common. The preferred lamotrigine dose was 25 mg twice daily. ### conclusions As there are few differences between the two treatments in efficacy, lamotrigine 25 mg twice daily might be the first choice as it is associated with fewer adverse effects in our population.


bevacizumab

triamcinolone

Anti-vascular endothelial growth factor combined with intravitreal steroids for diabetic macular oedema. The combination of steroid and anti-vascular endothelial growth factor (VEGF) intravitreal therapeutic agents could potentially have synergistic effects for treating diabetic macular oedema (DMO). On the one hand, if combined treatment is more effective than monotherapy, there would be significant implications for improving patient outcomes. Conversely, if there is no added benefit of combination therapy, then people could be potentially exposed to unnecessary local or systemic side effects. ### objectives To assess the effects of intravitreal agents that block vascular endothelial growth factor activity (anti-VEGF agents) plus intravitreal steroids versus monotherapy with macular laser, intravitreal steroids or intravitreal anti-VEGF agents for managing DMO. ### Search Methods We searched the Cochrane Central Register of Controlled Trials (CENTRAL) (which contains the Cochrane Eyes and Vision Trials Register) (2018, Issue 1); Ovid MEDLINE; Ovid Embase; LILACS; the ISRCTN registry; ClinicalTrials.gov and the ICTRP. The date of the search was 21 February 2018. ### Selection Criteria We included randomised controlled trials (RCTs) of intravitreal anti-VEGF combined with intravitreal steroids versus intravitreal anti-VEGF alone, intravitreal steroids alone or macular laser alone for managing DMO. We included people with DMO of all ages and both sexes. We also included trials where both eyes from one participant received different treatments. ### Data Collection And Analysis We used standard methodological procedures recommended by Cochrane.Two authors independently reviewed all the titles and abstracts identified from the electronic and manual searches against the inclusion criteria. Our primary outcome was change in best corrected visual acuity (BCVA) between baseline and one year. Secondary outcomes included change in central macular thickness (CMT), economic data and quality of life. We considered adverse effects including intraocular inflammation, raised intraocular pressure (IOP) and development of cataract. ### Main Results There were eight RCTs (703 participants, 817 eyes) that met our inclusion criteria with only three studies reporting outcomes at one year. The studies took place in Iran (3), USA (2), Brazil (1), Czech Republic (1) and South Korea (1). Seven studies used the unlicensed anti-VEGF agent bevacizumab and one study used licensed ranibizumab. The study that used licensed ranibizumab had a unique design compared with the other studies in that included eyes had persisting DMO after anti-VEGF monotherapy and received three monthly doses of ranibizumab prior to allocation. The anti-VEGF agent was combined with intravitreal triamcinolone in six studies and with an intravitreal dexamethasone implant in two studies. The comparator group was anti-VEGF alone in all studies; two studies had an additional steroid monotherapy arm, another study had an additional macular laser photocoagulation arm. Whilst we judged these studies to be at low risk of bias for most domains, at least one domain was at unclear risk in all studies.When comparing anti-VEGF/steroid with anti-VEGF monotherapy as primary therapy for DMO, we found no meaningful clinical difference in change in BCVA (mean difference (MD) -2.29 visual acuity (VA) letters, 95% confidence interval (CI) -6.03 to 1.45; 3 RCTs; 188 eyes; low-certainty evidence) or change in CMT (MD 0.20 μm, 95% CI -37.14 to 37.53; 3 RCTs; 188 eyes; low-certainty evidence) at one year. There was very low-certainty evidence on intraocular inflammation from 8 studies, with one event in the anti-VEGF/steroid group (313 eyes) and two events in the anti-VEGF group (322 eyes). There was a greater risk of raised IOP (Peto odds ratio (OR) 8.13, 95% CI 4.67 to 14.16; 635 eyes; 8 RCTs; moderate-certainty evidence) and development of cataract (Peto OR 7.49, 95% CI 2.87 to 19.60; 635 eyes; 8 RCTs; moderate-certainty evidence) in eyes receiving anti-VEGF/steroid compared with anti-VEGF monotherapy. There was low-certainty evidence from one study of an increased risk of systemic adverse events in the anti-VEGF/steroid group compared with the anti-VEGF alone group (Peto OR 1.32, 95% CI 0.61 to 2.86; 103 eyes).One study compared anti-VEGF/steroid versus macular laser therapy. At one year investigators did not report a meaningful difference between the groups in change in BCVA (MD 4.00 VA letters 95% CI -2.70 to 10.70; 80 eyes; low-certainty evidence) or change in CMT (MD -16.00 μm, 95% CI -68.93 to 36.93; 80 eyes; low-certainty evidence). There was very low-certainty evidence suggesting an increased risk of cataract in the anti-VEGF/steroid group compared with the macular laser group (Peto OR 4.58, 95% 0.99 to 21.10, 100 eyes) and an increased risk of elevated IOP in the anti-VEGF/steroid group compared with the macular laser group (Peto OR 9.49, 95% CI 2.86 to 31.51; 100 eyes).One study provided very low-certainty evidence comparing anti-VEGF/steroid versus steroid monotherapy at one year. There was no evidence of a meaningful difference in BCVA between treatments at one year (MD 0 VA letters, 95% CI -6.1 to 6.1, low-certainty evidence). Likewise, there was no meaningful difference in the mean CMT at one year (MD - 9 μm, 95% CI -39.87μm to 21.87μm between the anti-VEGF/steroid group and the steroid group. There was very low-certainty evidence on raised IOP at one year comparing the anti-VEGF/steroid versus steroid groups (Peto OR 0.75, 95% CI 0.16 to 3.55).No included study reported impact of treatment on patients' quality of life or economic data. None of the studies reported any cases of endophthalmitis. ### Authors Conclusions Combination of intravitreal anti-VEGF plus intravitreal steroids does not appear to offer additional visual benefit compared with monotherapy for DMO; at present the evidence for this is of low-certainty. There was an increased rate of cataract development and raised intraocular pressure in eyes treated with anti-VEGF plus steroid versus anti-VEGF alone. Patients were exposed to potential side effects of both these agents without reported additional benefit. The majority of the evidence comes from studies of bevacizumab and triamcinolone used as primary therapy for DMO . There is limited evidence from studies using licensed intravitreal anti-VEGF agents plus licensed intravitreal steroid implants with at least one year follow-up. It is not known whether treatment response is different in eyes that are phakic and pseudophakic at baseline.


Doxorubicin

ifosfamide

Perspectives on anthracyclines plus ifosfamide in advanced soft tissue sarcomas.  Doxorubicin and ifosfamide are currently the two main drugs for the treatment of soft tissue sarcomas in adults . Given in combination at full doses, with or without dacarbazine, these agents have induced higher response rates than were obtained with single-agent therapy. Because they involve considerable myelotoxicity, however, full-dose regimens should be reserved for patients with good performance status and without potential septic foci. Obviously, higher response rates do not automatically translate into improved survival. In soft tissue sarcomas, full-dose polychemotherapy will most probably provide a survival benefit only in selected patients in whom surgery can be performed in combination with chemotherapy. Prospective trials in such patients, although difficult to carry out, would be highly desirable. The information they would provide might help the clinician tailor treatment in a more rational way and improve chances of cure or long-term survival in at least some patient subgroups.


methylprednisolone

prednisolone

cyclosporine

Successful treatment of adolescent pemphigus vulgaris by immunoadsorption method. A 15-year-old girl with pemphigus vulgaris did not respond to oral administration of prednisolone at 45 mg/day. The skin and oral mucous membrane lesions recurred after effective treatments with methylprednisolone pulse therapy and combination therapy with prednisolone and cyclosporine . The finally successful treatment involved eleven cycles of immunoadsorption using a tryptophan column and administration of a moderate dose of prednisolone. Serum gamma-globulin level and anti-intercellular antibody titer decreased from 1.08 g/dl to 0.5 g/dl and 1:320 to 1:20, respectively. She has been well controlled with 21.5 mg/day prednisolone for 8 months after the final adsorption. Considering the physical, mental and social situation of adolescent student patients, immunoadsorption is a highly preferable choice among a variety of treatment modalities for pemphigus vulgaris because it makes the term of hospitalization shorter and avoids undesirable side effects from initial high dose corticosteroids.


colistin

ciprofloxacin

Co-Delivery of Ciprofloxacin and Colistin in Liposomal Formulations with Enhanced In Vitro Antimicrobial Activities against Multidrug Resistant Pseudomonas aeruginosa. This study aims to develop liposomal formulations containing synergistic antibiotics of colistin and ciprofloxacin for the treatment of infections caused by multidrug-resistant Pseudomonas aeruginosa. ### methods colistin (Col) and ciprofloxacin (Cip) were co-encapsulated in anionic liposomes by ammonium sulfate gradient. Particle size, encapsulation efficiency, in vitro drug release and in vitro antibiotic activities were evaluated. ### results The optimized liposomal formulation has uniform sizes of approximately 100 nm, with encapsulation efficiency of 67.0% (for colistin) and 85.2% (for ciprofloxacin). Incorporation of anionic lipid (DMPG) markedly increased encapsulation efficiency of colistin (from 5.4 to 67.0%); however, the encapsulation efficiency of ciprofloxacin was independent of DMPG ratio. Incorporation of colistin significantly accelerated the release of ciprofloxacin from the DMPG anionic liposomes . In vitro release of ciprofloxacin and colistin in the bovine serum for 2 h were above 70 and 50%. The cytotoxicity study using A549 cells showed the liposomal formulation is as non-toxic as the drug solutions. Liposomal formulations of combinations had enhanced in vitro antimicrobial activities against multidrug resistant P. aeruginosa than the monotherapies. ### conclusions Liposomal formulations of two synergistic antibiotics was promising against multidrug resistant P. aeruginosa infections.


flutamide

bicalutamide

Clinical outcome of maximum androgen blockade using flutamide as second-line hormonal therapy for hormone-refractory prostate cancer. To investigate the efficacy of maximum androgen blockade (MAB) using flutamide as second-line hormonal therapy for advanced hormone-refractory prostate cancer (HRPC). ### Patients And Methods The study included 55 patients with HRPC who were treated with MAB using flutamide (375 mg daily) as second-line hormonal therapy. All patients had previously received bicalutamide combined with either surgical or medical castration as first-line hormonal therapy, which failed. The effect of the second-line therapy was evaluated by serum prostate-specific antigen (PSA) level alone, and the response defined as a decrease of >50% from the baseline PSA at the start of second-line therapy. ### results On initiating second-line hormonal therapy there was a reduction in the PSA level in 25 of the 55 patients (45%), among whom 12 (22%) were regarded as responders, while the PSA level continued to increase in the remaining 30 (55%). The median (range) duration of the PSA response was 6 (1-13) months. During the observation period there were no severe side-effects from the second-line MAB therapy. Patients without bone metastases or whose disease progressed >1 year after first-line therapy had a significantly higher incidence of PSA response to second-line therapy, despite no significant effect of other factors examined on the PSA response to second-line therapy. Furthermore, the cause-specific survival in responders to second-line therapy was significantly better than that in nonresponders; however, multivariate analysis showed that no factors, including response to second-line therapy, could be used as independent predictors of cause-specific survival. ### conclusions MAB using flutamide as second-line hormonal therapy can give a comparatively favourable PSA response with no severe side-effects ; therefore , this therapy may be suitable for patients with HRPC after primary MAB using bicalutamide has failed , particularly in those with no bone metastases or whose disease has progressed for > 1 year after first-line therapy .


decitabine

vorinostat

Phase I study of decitabine in combination with vorinostat in patients with advanced solid tumors and non-Hodgkin 's lymphomas . PURPOSE: This phase I study evaluated the safety, tolerability, pharmacokinetics and preliminary efficacy of the combination of decitabine with vorinostat.  PATIENTS AND METHODS: Patients with advanced solid tumors or non-Hodgkin's lymphomas were eligible. Sequential and concurrent schedules were studied.  RESULTS: Forty-three patients were studied in 9 different dose levels (6 sequential and 3 concurrent). The maximum tolerated dose (MTD) on the sequential schedule was decitabine 10 mg/m(2)/day on days 1-5 and vorinostat 200 mg three times a day on days 6-12. The MTD on the concurrent schedule was decitabine 10 mg/m(2)/day on days 1-5 with vorinostat 200 mg twice a day on days 3-9. However, the sequential schedule of decitabine 10 mg/m(2)/day on days 1-5 and vorinostat 200 mg twice a day on days 6-12 was more deliverable than both MTDs with fewer delays on repeated dosing and it represents the recommended phase II (RP2D) dose of this combination. Dose-limiting toxicities during the first cycle consisted of myelosuppression, constitutional and gastrointestinal symptoms and occurred in 12/42 (29%) patients evaluable for toxicity. The most common ≥ grade 3 adverse events were neutropenia (49% of patients), thrombocytopenia (16%), fatigue (16%), lymphopenia (14%), and febrile neutropenia (7%). Disease stabilization for ≥ 4 cycles was observed in 11/38 (29%) evaluable patients.  CONCLUSION: The combination of decitabine with vorinostat is tolerable on both concurrent schedules in previously treated patients with advanced solid tumors or non-Hodgkin's lymphomas. The sequential schedule was easier to deliver. The combination showed activity with prolonged disease stabilization in different tumor types.


Epirubicin

cyclophosphamide

Combined 5-fluorouracil infusion with fractionated epirubicin and cyclophosphamide in advanced breast cancer. 5-fluorouracil (5-FU) given by continuous infusion (c.i.) allows higher dose delivery, causes less myelosuppression, and may interfere with repair of DNA damage caused by epirubicin and cyclophosphamide. With this rationale, we conducted a phase II study to test the activity and toxicity of 5-FU c.i., epirubicin, and cyclophosphamide in patients with metastatic breast cancer (MBC). Twenty-eight patients with MBC were entered in the trial. 5-FU (200 mg/m(2)) was administered by c.i. from day 1 to day 20. Epirubicin ( 35 mg/m(2 ) ) and cyclophosphamide ( 400 mg/m(2 ) ) were administered from day 2 to day 4 , every 4 weeks . All patients were evaluable for response and toxicity. A total of 125 courses of chemotherapy were administered, with a median of 4 per patient (range: 2--6). Toxicity, assessed using World Health Organization criteria, was as follows: nausea and vomiting grade III--IV occurred in 36%, alopecia (grade III) in 86%, neutropenia (grade III--IV) in 50%, and cardiac toxicity grade I--II in 11% of patients. Five patients (17.9%) had a complete response to therapy, and 16 (57.1%) had a partial response (response rate 75%, 95% CI 55--89%). Disease stability and progression occurred in 4 (14.3%) and 3 (10.7%) patients, respectively. Median time to progression was 13.1 months (range: 3.4--66.9+), and median survival time was 27.7 months (range: 5.4--67.1+). Outpatient treatment with combined 5-FU c.i., epirubicin, and cyclophosphamide shows high activity in advanced breast cancer and gives prolonged remission with acceptable toxicity.


carvedilol

spironolactone

Successful bridge to recovery with VAD implantation for anthracycline-induced cardiomyopathy. Anthracyclines are effective antineoplastic drugs, but they are known to be cardiotoxic. Recovery of cardiac function is rare. A few studies on implantation of a ventricular assist device (VAD) have been performed for anthracycline-induced cardiomyopathy. Recovery of left ventricular (LV) function with an LVAD is also rare. Recently, several adjunctive therapies were attempted to restore ventricular function. We report a successful bridge to recovery of ventricular function using VAD implantation for anthracycline-induced cardiomyopathy. The patient was a 57-year-old man who had been diagnosed with diffuse large B-cell lymphoma (DLBCL) at age 52. Combination chemotherapy including hydroxydaunorubicin was started. Complete remission was achieved after chemotherapy. Heart failure symptoms such as fatigue, dyspnea on exertion, and weight gain appeared 5 months later. A cardiac resynchronization device was implanted. His heart function deteriorated. He underwent implantation of a Toyobo LVAD and mitral annuloplasty. After implantation, he was prescribed carvedilol with spironolactone. He was weaned from the LVAD on postoperative day (POD) 239 and discharged on POD 37 after weaning. He remained in New York Heart Association classes within the first- to second-degree range, the LV dimention diastolic/systolic ratio was 56/46 mm, ejection fraction 38%, and mitral regurgitation mild at 3 years after weaning from the LVAD. Our patient could be weaned from LVAD probably due to the combination management strategy employing mitral valvuloplasty , use of cardiac resynchronization therapy , and taking carvedilol with spironolactone . Further studies will be needed to clarify the efficacy of these adjunctive therapies.


hydroxyzine

cetirizine

Pharmacokinetics of hydroxyzine and cetirizine following oral administration of hydroxyzine to exercised Thoroughbred horses. hydroxyzine is a first-generation antihistamine and cetirizine, a second-generation antihistamine and active metabolite of hydroxyzine. hydroxyzine is commonly used in performance horses and as such its use in closely regulated; however, there are no published studies suitable for establishing appropriate regulatory recommendations. In the current study, 12 exercised Thoroughbred research horses received a single oral administration of 500 mg of hydroxyzine. Blood and urine samples were collected prior to and up to 96 hr postdrug administration and concentrations of hydroxyzine and cetirizine determined using liquid chromatography-tandem mass spectrometry. A joint parent/metabolite population 2-compartment pharmacokinetic model with first-order absorption and elimination was utilized to describe the pharmacokinetics of both compounds. Serum hydroxyzine and cetirizine concentrations were above the limit of quantitation ( 0.1 ng/ml ) of the assay at 96 hr (the last time point sampled). The terminal half-life was 7.41 and 7.13 hr for hydroxyzine and cetirizine, respectively. Findings from this study suggest that a prolonged withdrawal time should be observed if this compound is used in performance administered to performance horses and is classified as prohibited substance by the applicable regulatory body.


everolimus

vinorelbine

vinorelbine

VicTORia: a randomised phase II study to compare vinorelbine in combination with the mTOR inhibitor everolimus versus vinorelbine monotherapy for second-line chemotherapy in advanced HER2-negative breast cancer. Improving the outcome of patients with HER2-negative metastatic breast cancer experiencing tumour progression following first-line chemotherapy remains an urgent medical need. The purpose of the VicTORia trial was to show superiority of everolimus in combination with vinorelbine versus vinorelbine monotherapy as second-line chemotherapy for patients with advanced HER2 negative breast cancer. ### methods In this randomised phase II trial, 133 patients were recruited in 32 centres in Germany. Patients were randomised 1:1 to second-line chemotherapy either with vinorelbine plus everolimus (arm1) or vinorelbine alone (arm2). Primary endpoint was progression-free survival (PFS). Secondary endpoints were PFS rate at 6 months, overall survival (OS), overall response rate (ORR) and safety. Baseline PI3 K mutational status was determined in plasma samples. ### results Median progression-free survival was not different between arms (arm1 vs. arm2: 4.01 months, 95% CI 2.40-6.09 vs. 4.08, 95% CI 2.80-5.33). PFS rate at 6 months (arm1 vs. arm2: 39.4%, 95% CI 27.6-50.9% vs. 36.6%, 95% CI 24.6-48.6%), median OS (arm1 vs. arm2: 16.3 months, 95% CI 11.4-19.0 vs. 13.8 months, 95% CI 10.2-19.1) and ORR were not different between arms. Most frequent grade 3/4 adverse events were neutropenia (50% vs. 40%), gastrointestinal toxicities (19.1% vs. 6.1%), and infections (19.1% vs. 7.7%). PI3 K mutational status was neither associated with PFS nor with OS. ### conclusion Although well tolerated , the efficacy of everolimus and vinorelbine combination therapy was not superior to vinorelbine monotherapy . There was no correlation between PI3 K mutational status and efficacy. EudracCT No 2011-001024-38, ClinicalTrials.gov No NCT01520103.


adalimumab

tocilizumab

rituximab

chloroquine

hydroxychloroquine

Transcriptomic signatures and repurposing drugs for COVID-19 patients: findings of bioinformatics analyses. The novel coronavirus SARS-CoV-2 is damaging the world's social and economic fabrics seriously. Effective drugs are urgently needed to decrease the high mortality rate of COVID-19 patients. Unfortunately, effective antiviral drugs or vaccines are currently unavailable. Herein, we systematically evaluated the effect of SARS-CoV-2 on gene expression of both lung tissue and blood from COVID-19 patients using transcriptome profiling. Differential gene expression analysis revealed potential core mechanism of COVID-19-induced pneumonia in which IFN-α, IFN-β, IFN-γ, TNF and IL6 triggered cytokine storm mediated by neutrophil, macrophage, B and DC cells. Weighted gene correlation network analysis identified two gene modules that are highly correlated with clinical traits of COVID-19 patients, and confirmed that over-activation of immune system-mediated cytokine release syndrome is the underlying pathogenic mechanism for acute phase of COVID-19 infection. It suggested that anti-inflammatory therapies may be promising regimens for COVID-19 patients. Furthermore, drug repurposing analysis of thousands of drugs revealed that TNFα inhibitor etanercept and γ-aminobutyric acid-B receptor (GABABR) agonist baclofen showed most significant reversal power to COVID-19 gene signature, so we are highly optimistic about their clinical use for COVID-19 treatment. In addition , our results suggested that adalimumab , tocilizumab , rituximab and glucocorticoids may also have beneficial effects in restoring normal transcriptome , but not chloroquine , hydroxychloroquine or interferons . Controlled clinical trials of these candidate drugs are needed in search of effective COVID-19 treatment in current crisis.


docetaxel

doxorubicin

In vitro evaluation of schedule-dependent interactions between docetaxel and doxorubicin against human breast and ovarian cancer cells. docetaxel, a novel member of the taxoid family, has shown greater potency than paclitaxel in the treatment of advanced breast cancer and certain other solid tumors. The promising clinical activity of docetaxel has also promoted considerable interest in combining this drug with other antitumor agents. In this study, we assessed the cytotoxic interaction between docetaxel and doxorubicin administered at various schedules to human breast and ovarian cancer cells. Through a series of in vitro assays including DNA fragmentation analyses, 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assays, and flow cytometric analyses, we found that the antagonistic interaction occurred when tumor cells were exposed to the two drugs simultaneously or exposed to doxorubicin before docetaxel. However, no antagonism was observed when docetaxel was added before doxorubicin. Further analyses demonstrated that doxorubicin could interfere with the cytotoxic effect of docetaxel on both mitotic arrest and apoptotic cell death. In addition , biochemical examinations revealed that docetaxel could induce phosphorylation of both bcl-2 and c-raf-1 , but these changes were inhibited when tumor cells were pretreated or simultaneously treated with doxorubicin . These results indicate that the interaction between docetaxel and doxorubicin is highly schedule dependent. Exposure of tumor cells to doxorubicin before docetaxel could result in pronounced antagonism. The optimal schedule for this combination might be sequential exposure to docetaxel followed by doxorubicin.


fluorouracil

leucovorin

Enhancement of radiation-induced downstaging of rectal cancer by fluorouracil and high-dose leucovorin chemotherapy . To determine if fluorouracil (5-FU) plus high-dose leucovorin (LV) enhances local response in patients receiving preoperative radiation therapy (RT) for adenocarcinoma of the rectum, we compared the degree of downstaging in patients receiving preoperative RT with or without chemotherapy. ### Patients And Methods For this comparison, three groups of patients who were treated with identical doses and techniques of preoperative pelvic RT (total dose of 5,040 cGy) were examined. Group 1 included 20 patients with unresectable disease who received combined RT and LV/5-FU. Group 2 included 11 patients with unresectable disease who received preoperative RT. Group 3 included 21 patients with invasive, resectable, primary disease who received preoperative RT. ### results Patients with unresectable disease who received LV/5-FU had a higher rate of pathologic complete response (20% v 0%) and a lower incidence of positive nodes (30% v 64%) compared with those who did not receive chemotherapy. Even when the most favorable group of patients was included (group 3), patients who received LV/5-FU still had a higher complete response rate (20% v 6%) and a lower incidence of positive nodes (30% v 53%) compared with those who received RT without LV/5-FU. Of those patients with initially unresectable disease, the resectability rate was higher in those who received LV/5-FU compared with those who did not receive LV/5-FU (90% v 64%). Patients who received LV/5-FU experienced slightly more grade 1 to 2 fatigue, stomatitis, nausea, and grade 3 diarrhea, tenesmus, and dysuria. ### conclusions Despite the fact that patients who received chemotherapy (group 1) had more advanced disease compared with those with resectable disease (group 3), the addition of LV/5-FU increased the resectability and downstaging rates. The ultimate impact of a complete response as well as a decrease in the incidence of pelvic nodes on local control and survival remains to be determined. However, given the enhancement of down-staging in patients with unresectable rectal cancer, we are encouraged by the combined modality approach.


nivolumab

ipilimumab

Final analysis of a phase II study of nivolumab in combination with ipilimumab for unresectable chemotherapy-naive advanced melanoma . nivolumab plus ipilimumab combination is currently one of the preferred regimens for advanced melanoma in recently updated clinical practice guidelines. However, the evidence on the efficacy of the combination for acral or mucosal subtypes remains less robust. This is the final analysis of a multicenter, open-label, uncontrolled phase II study that investigated the long-term efficacy and safety in treatment-naive Japanese patients with advanced melanoma, including acral or mucosal subtypes, and subsequent therapy after discontinuation of the investigational agents. Patients received four doses of nivolumab (1 mg/kg i.v.) in combination with ipilimumab (3 mg/kg i.v.) at 3-week intervals, followed by doses of nivolumab (3 mg/kg i.v.) at 2-week intervals. The median follow-up period was 20.8 months (range, 5.2-35.0). The centrally and locally assessed objective response rates were both 43.3% (13/30; 95% confidence interval [CI], 25.5-62.6). Median progression-free survival was not reached (95% CI, 3.02-not reached), and median overall survival was also not reached (95% CI, 19.52-not reached). The 30-month progression-free survival and overall survival rates were 50.3% and 54.2%, respectively. No new safety concerns were detected. After discontinuation of the investigational agents, 83.3% of patients received some form of subsequent therapy including 43.3% of patients who received nivolumab monotherapy and 26.7% of patients who received radiotherapy. Of the four patients who discontinued the investigational agents because of immune-related adverse events, two received subsequent therapy (nivolumab and ipilimumab, respectively) and the other two showed long-term treatment-free survival (659 and 590 days, respectively). Long-term survival with nivolumab plus ipilimumab was observed in Japanese patients with melanoma including acral and mucosal subtypes, which is consistent with the CheckMate 067 study. Many patients continued to receive some form of treatment safely after stopping treatment with nivolumab plus ipilimumab.


infliximab

rituximab

Cost effectiveness of different treatment strategies in the treatment of patients with moderate to severe rheumatoid arthritis in china. To analyse the cost-effectiveness of traditional disease-modifying anti-rheumatic drugs (tDMARDs) compared to biological therapies from the perspective of Chinese society. ### Methodology Principal Findings A mathematical model was developed by incorporating the clinical trial data and Chinese unit costs and treatment sequences from a lifetime perspective. Hypothetical cohorts with moderate to severe RA were simulated. The primary outcome measure-quality-adjusted life years (QALYs)-was derived from disease severity (HAQ scores). Primary analysis included drug costs, monitoring costs, and other costs. Probabilistic and one-way sensitivity analyses were performed. Treatment sequences that included TNF antagonists and rituximab produced a greater number of QALYs than tDMARDs alone or TNF antagonists plus DMARDs. In comparison with tDMARDs, the incremental cost-effectiveness ratios (ICERs) for etanercept, infliximab, and adalimumab without rituximab were $77,357.7, $26,562.4 and $57,838.4 per QALY and $66,422.9, $28,780.6 and $50,937.6 per QALY, for etanercept, infliximab, and adalimumab with rituximab. No biotherapy was cost-effective under the willingness to pay threshold when the threshold was 3 times the per capita GDP of China. When 3 times the per capita GDP of Shanghai used as the threshold, infliximab and rituximab could yield nearly 90% cost-effective simulations in probabilistic sensitivity analysis. ### Conclusions Significance tDMARD was the most cost-effective option in the Chinese healthcare setting. In some relatively developed regions in China , infliximab and rituximab may be a favorable cost-effective alternative for moderate to severe RA .


Topiramate

metformin

A randomized, double-blind, placebo-controlled, multicenter study to assess the efficacy and safety of topiramate controlled release in the treatment of obese type 2 diabetic patients. This is a randomized, placebo-controlled study of the weight-loss efficacy and safety of a controlled-release (CR) formulation of topiramate in overweight and obese patients with type 2 diabetes treated with diet and exercise alone or in combination with metformin. ### Research Design And Methods Patients with type 2 diabetes, BMI > or =27 kg/m2, A1C >6.5 and <11.0%, treated with diet and exercise alone or in combination with metformin monotherapy were enrolled. Patients were randomized to placebo or topiramate CR titrated up to 175 mg/day. Treatment consisted of a 7-week titration phase followed by a 9-week maintenance phase. ### results A total of 111 subjects were randomized and analyzed. By the end of week 16, patients in the placebo and topiramate groups lost 2.5 and 6.0 kg, which represented 2.3 and 5.8%, respectively, of their baseline body weight (P < 0.001 vs. placebo). A1C improved from a baseline of 7.4% in the placebo and 7.6% in the topiramate groups to 7.1 and 6.7%, respectively, representing a 0.4 and 0.9% reduction from baseline, respectively (P < 0.001 vs. placebo). topiramate also significantly reduced blood pressure and urinary albumin excretion. Adverse events were predominantly neuropsychiatric or central and peripheral nervous system related. ### conclusions Topiramate CR treatment produced significant weight loss and meaningful improvements in A1C and blood pressure in obese patients with type 2 diabetes treated with diet and exercise or in combination with metformin . However, the central nervous system and psychiatric adverse event profile of topiramate CR makes it unsuitable for the treatment of obesity and diabetes.


oxaliplatin

fluorouracil

leucovorin

Therapeutic efficacy and toxicity of bolus application of chemotherapy protocol in the treatment of metastatic colorectal cancer.  To compare efficacy and toxicity of bolus application of chemotherapy protocol , oxaliplatin , fluorouracil ( bolus ) , leucovorin ( folfox ) between two groups of patients in the therapy of metastatic colorectal carcinoma ( mCRC ) . ### methods A total of 63 patients were treated for mCRC in the period January 2009 - January 2010 at the Department of Oncology of the Cantonal Hospital Zenica, Bosnia and Herzegovina (first group, 30 patients) and at the Department of Oncology of the Clinical Hospital Centre Bežanijska kosa in Belgrade, Serbia, in the period January 2005 - January 2006 (second group, 33 patients). The patients were treated according the same protocol, i.v. bolus infusion, but in different day intervals (D), 1, 8, 15/28 days or D1-D5/28 days, respectively. In all patients the following factors were analyzed: tumor response, overall survival (OS), progression free survival, hematological and non-hematological toxicity . ### results Colon was the primary localization in almost two thirds of patients. There was no statistically significant difference between the groups according to the age, hematological and non-hematological toxicity, as well as in achieved OS. Progression free survival expressed in months was in average 5 months though with a large range between minimal and maximal survival time. ### conclusion Both groups have shown equivalent efficacy to applied chemotherapy protocols. Overall survival in the two groups matched data from the literature. Further research should confirm success of the combination of chemotherapy protocols and their combination with the biological therapy.


Verapamil

quinine

Combination chemotherapy with cyclophosphamide, vincristine, adriamycin, and dexamethasone (CVAD) plus oral quinine and verapamil in patients with advanced breast cancer. We evaluated the question of whether the chemosensitizers verapamil and quinine given orally to breast cancer patients failing combination chemotherapy alone would result in additional clinical responses. In vitro studies reported here showed verapamil sensitization of Adriamycin resistance in 18.8% of fresh human breast cancer specimens tested. Patients (27) were first treated with cyclophosphamide, vincristine, Adriamycin and dexamethasone (CVAD) alone. Verapamil and quinine were added in patients with tumors failing to respond or progressing on CVAD alone . Following treatment with CVAD alone there were no complete remissions and 3 patients (11%) developed partial remissions lasting 5.5, 8, 10.5 months. With the addition of verapamil and quinine to the CVAD regimen, one patient (4%) developed a complete remission of 11.8 months duration and 4 additional patients (15%) developed partial remissions lasting 2.8, 17.3, 19 and > 40 months. Thus, the overall rate of CVAD sensitization by verapamil and quinine was 19%. Treatment with CVAD plus verapamil and quinine was generally well tolerated with observed toxicities including: myelosuppression, neuropathy, Cushingoid symptoms and tinnitus and/or dizziness due to quinine. We conclude that addition of the non-cytotoxic chemosensitizers verapamil and quinine to CVAD in patients failing CVAD alone results in additional clinical responses in a small percentage of patients, some with long term durations. The results of this study lend credence to the notion that non-cytotoxic chemosensitizers can enhance the clinical activity of combination chemotherapy and the search for more effective and less toxic chemosensitizers continues.


dipyridamole

epirubicin

[Studies on reversing effect of multidrug resistance by dipyridamole. II. Inhibition of epirubicin efflux from resistant cells by dipyridamole and its pharmacological effect]. We have previously reported that dipyridamole increases the cytotoxicity of epirubicin and alters the cell cycle in doxorubicin-resistant (P388/DOX) cells, increasing the accumulation of G2/M phase by blocking the cell cycle. In cultured cells, dipyridamole increased dose-dependently the intracellular accumulation of epirubicin in the resistant cells. Simultaneous exposure of the resistant cells to epirubicin and 100 microM dipyridamole resulted in a 4.2-fold increase in proportion to the control level of epirubicin after 60 min. dipyridamole inhibited the enhanced efflux of epirubicin in doxorubicin-resistant cells. However , dipyridamole had no effect on both the influx and efflux of epirubicin in doxorubicin-sensitive cells . In mice, lethal and bone marrow toxicity induced by epirubicin were potentiated by administration of high-dose of dipyridamole. In addition, in vivo results also demonstrated that dipyridamole in combination with epirubicin produced a significant reversal of the in vivo antitumor activity of epirubicin in mice bearing P388/DOX cells. These data imply the enhancement effects of dipyridamole on the efficacy and toxicity of epirubicin.


docetaxel

flavopiridol

Efficacy of sequential treatment of HCT116 colon cancer monolayers and xenografts with docetaxel, flavopiridol, and 5-fluorouracil. Clinical treatment of solid tumors with docetaxel, flavopiridol, or 5-fluorouracil (5-FU) often encounters undesirable side effects and drug resistance. This study aims to evaluate the potential role of combination therapy with docetaxel , flavopiridol , or 5-FU in modulating chemosensitivity and better understand how they might be used clinically . ### methods HCT116 colon cancer cells were treated with docetaxel, flavopiridol, and 5-FU in several different administrative schedules in vitro, either sequentially or simultaneously. Cell survival was measured by MTT assay. The activity of caspase-3 was determined by caspase-3 assays and the soft agar colony assay was used to test the colony formation of HCT116 cells in soft agar. We also established xenograft models to extend in vitro observations to an in vivo system. ### results The maximum cytotoxicity was found when human colon cancer HCT116 cells were treated with docetaxel for 1 h followed by flavopiridol for 24 h and 5-FU for another 24 h. This sequential combination therapy not only inhibits tumor cell growth more strongly compared to other combination therapies but also significantly reduces colony formation in soft agar and augments apoptosis of HCT116 cells. Sequencing of docetaxel followed 1 h later by flavopiridol, followed 24 h later by 5-FU in xenograft models, also resulted in delayed tumor growth and higher survival rate. ### conclusion These results highlight the importance of an administrative schedule when combining docetaxel with flavopiridol and 5-FU, providing a rationale explanation for its development in clinical trials.


Dipyridamole

dipyridamole

acetylsalicyclic acid

The course of pregnancy in patients with artificial heart valves. Twenty-five women with prosthetic heart valves (PHV) became pregnant 28 times. Twenty-six of the pregnancies occurred while the patients were receiving oral anticoagulants and these were continued throughout in 25 pregnancies. Dipyridamole or dipyridamole and acetylsalicyclic acid were used in 22 pregnancies . Eighteen infants were delivered, one with a congenital corneal leukoma; none had hemorrhagic complications; their psychomotor development was normal. Nine women aborted 10 times, including patients with two PHV, pelvic trauma and self-induced abortion. We could not detect excess anticoagulation in eight of the nine who had spontaneous losses; excess anticoagulation occurred five weeks before an abortion. There were no maternal deaths despite numerous complications; in two women, brain embolism was related to short interruptions of anticoagulation. The details of management are mentioned. We lack enough evidence to suggest routine sterilization, routine interruption of coumarin therapy during pregnancy or routine interruption of pregnancy in women with certain types and models of PHV; however, pregnancy under such conditions, plus antithrombotic therapy, carries a high risk for the product and a potential teratogenic effect. Women with one or two PHV can have children if their management is closely supervised and if extreme care is taken with the use of oral anticoagulants.


Bevacizumab

trastuzumab

Neoadjuvant bevacizumab, trastuzumab, and chemotherapy for primary inflammatory HER2-positive breast cancer (BEVERLY-2): an open-label, single-arm phase 2 study.  Bevacizumab and trastuzumab are efficacious for treatment of advanced or HER2-positive metastatic breast cancer ; however , few data exist for this regimen in inflammatory breast cancer . In our phase 2 trial, we aimed to assess efficacy and safety of neoadjuvant bevacizumab combined with trastuzumab and chemotherapy in patients with primary HER2-positive inflammatory breast cancer. ### methods In our phase 2, multicentre, open-label, single-arm, non-comparative trial, we enrolled women (aged ≥ 18 years) with histologically confirmed HER2-positive non-metastatic inflammatory breast cancer at private or public oncology centres in France. Before surgery, patients were treated with fluorouracil, epirubicin, cyclophosphamide, and bevacizumab (cycles 1-4) and docetaxel, bevacizumab, and trastuzumab (cycles 5-8) in 3-week cycles. After surgery, patients received adjuvant radiotherapy, trastuzumab, and bevacizumab. For the primary endpoint, we assessed the proportion of patients who achieved a pathological complete response (defined by central review of surgical specimens according to Sataloff classification, counting missing data as failure) and adverse events in all enrolled patients. This study is registered with ClinicalTrials.gov, number NCT00717405. ### findings Between Oct 23, 2008, and Oct 28, 2009, we enrolled 52 patients at 21 centres. 42 (81%) of 52 patients received all eight cycles of neoadjuvant therapy and 49 (94%) underwent surgery. After neoadjuvant therapy, 33 of 52 patients had a pathological complete response according to central review (63·5%, 95% CI 49·4-77·5). The most common adverse events were asthenia and nausea (both occurred in 36 [69%] of 52 patients). 25 (48%) patients had grade 3-4 neutropenia, which was the most common grade 3-4 adverse event. Only one grade 3 or worse adverse event regarded as related to bevacizumab was reported (hypertension, one patient). Four patients (8%) had cardiac failure. ### interpretation Neoadjuvant treatment with bevacizumab, trastuzumab, and chemotherapy was efficacious and well tolerated in patients with previously untreated primary inflammatory breast cancer. Further confirmation of use of bevacizumab in inflammatory breast cancer is needed. ### funding Roche (France).


ampicillin

erythromycin

chloramphenicol

kanamycin

doxycycline

Antimicrobial susceptibilities of exfoliative toxigenic and non-toxigenic Staphylococcus hyicus strains in Japan. Staphylococcus hyicus isolates (n=207), including 150 exfolitative toxigenic and 57 non-toxigenic strains, were examined for their susceptibility to 13 antimicrobial agents by using the dehydrated 96-well MIC panel system. The frequency of their resistance to penicillin and ampicillin was 76.8 % ( 159/207 ) , followed by erythromycin ( 56 % , 116/207 ) , trimethoprim-sulfamethoxazole ( 28.5 % , 59/207 ) , chloramphenicol ( 24.2 % , 50/207 ) , kanamycin ( 19.8 % , 41/207 ) , and doxycycline ( 1.4 % , 3/207 ) . Resistance to chloramphenicol and trimethoprim-sulfamethoxazole was significantly higher in toxigenic strains than non-toxigenic strains (p<0.01), whereas kanamycin and erythromycin resistance was significantly higher in non-toxigenic strains (p<0.01 and <0.05, respectively). Resistance to two or more antimicrobials was observed in 85.5% (177/207) of total strains, with a significantly higher occurrence in toxigenic strains (89.3%, 134/150 vs. 75.4%, 43/57; p<0.05).


bupivacaine

pancuronium

bupivacaine

pancuronium

Effect of 50% enantiomeric excess bupivacaine mixture combined with pancuronium on neuromuscular transmission in rat phrenic nerve-diaphragm preparation; a pilot study. Local anaesthetics are drugs that are widely used in clinical practice. However, the effects of these drugs on the neuromuscular junction and their influence on the blockade produced by non-depolarising neuromuscular blocking drugs are still under investigation. The aim of this study was to evaluate, in vitro, the influence of a 50% enantiomeric excess bupivacaine mixture on neuromuscular transmission and neuromuscular block produced by pancuronium. ### methods Rats were distributed into three groups ( n = 5 ) according to the drug studied namely , 50 % enantiomeric excess bupivacaine mixture ( 5 μg/mL ) ; pancuronium ( 2 μg/mL ) ; 50 % enantiomeric excess bupivacaine mixture + pancuronium . The following parameters were evaluated: (1) Effects of a 50% enantiomeric excess bupivacaine mixture on membrane potential (MP) and miniature endplate potentials (MEPPs); (2) amplitude of diaphragmatic response before and 60 min after the addition of a 50% enantiomeric excess bupivacaine mixture; the degree of neuromuscular block with pancuronium and pancuronium combined with a 50% enantiomeric excess bupivacaine mixture. ### results A 50% enantiomeric excess bupivacaine mixture did not alter the amplitude of muscle response (MP) but decreased the frequency and amplitude of MEPP. The block produced by pancuronium was potentiated by a 50% enantiomeric excess bupivacaine mixture. ### conclusion A 50% enantiomeric excess bupivacaine mixture used alone did not affect neuromuscular transmission, but potentiated the neuromuscular block produced by pancuronium. No action was shown on the muscle fibre, and alterations on MEPPs demonstrated a presynaptic action.


temazepam

fentanyl

thiopentone

vecuronium

The plasma ACTH, AVP, CRH and catecholamine responses to conventional and laparoscopic cholecystectomy. We compared the responses of the stress hormones, cortisol, ACTH, vasopressin (AVP), corticotrophin releasing hormone (CRH) and catecholamines to elective conventional and laparoscopic cholecystectomy. ### design A right upper quadrant transverse incision was used for conventional cholecystectomy, and four 1-2-cm incisions for the laparoscopic procedure (for insertion of surgical instruments, diathermy, fibreoptic telescope and light source, and carbon dioxide insufflation). Blood was sampled immediately prior to premedication ( temazepam ) , after induction of anaesthesia ( fentanyl and thiopentone ) and at 10-minute intervals until the end of the procedure ( N2O maintenance , vecuronium relaxation ) . A blood sample was taken after reversal, and then at 10-minute intervals for 50 minutes. Plasma sodium and blood pressure were measured at similar intervals. Results are expressed as mean +/- standard error. ### patients Twelve patients were studied (six in each group). ### measurements Peptide hormones were measured by radioimmunoassay, cortisol by ELISA and catecholamines by HPLC. ### results The mean premedication hormone values for the conventional and laparoscopic procedures did not increase significantly after induction of anaesthesia. Within 10 minutes of the first incision, however, there was a marked concordant rise in mean plasma ACTH and AVP levels for both procedures (conventional: ACTH, from a premedication value of 10.2 +/- 1.7 to 80.1 +/- 14.3 pmol/l, AVP from 1.2 +/- 0.4 to 117 +/- 24 pmol/l, P < 0.01 for both hormones; laparoscopic: ACTH from 5.8 +/- 2.6 to 55.1 +/- 26.0 pmol/l, AVP from 1.6 +/- 0.11 to 49.2 +/- 27.09 pmol/l). At the end of both types of operation mean levels of ACTH and AVP were still elevated, although the ACTH: AVP ratio had increased. Greater variability in ACTH and AVP responses was seen in the laparoscopic than in the conventional procedure, three patients showing a relatively small response to surgery. Total secretion of ACTH during both types of surgery was not significantly less both during (P < 0.05), and after (P < 0.01) laparoscopic surgery. For both procedures, the timing of AVP and ACTH peaks was significantly related (P < 0.002). A small but significant rise in CRH was observed 30 minutes after the start of surgery for both procedures P < 0.05). The timing of CRH and ACTH peaks was unrelated. The maximum mean plasma cortisol level for the conventional procedure (1268 +/- 147 nmol/l) was reached 20 minutes after reversal of anaesthesia and remained at this level until the end of sampling. The cortisol response was comparable during the laparoscopic procedure but was beginning to fall at 60 minutes post-operatively. Plasma adrenaline responses to the two types of surgery were not significantly different, but the plasma total noradrenaline response to laparoscopic surgery as indicated by the response area during the first 20 minutes was significantly increased (P < 0.02). Plasma sodium, renin activity and initial systolic blood pressure fall were not significantly different during the two procedures. ### conclusions For both procedures, the peak of ACTH secretion after incision is likely to be AVP dependent, and the timing of peak levels of these two hormones was significantly related. Subsequent ACTH secretion may be the result of an interaction between AVP and CRH. Laparoscopic cholecystectomy results in a smaller AVP rise than does the conventional procedure, and plasma AVP falls more rapidly post-operatively. During the period of observation, ACTH, CRH, cortisol and adrenaline responses were not significantly lessened by the laparoscopic approach, but there was a significant increase in the noradrenaline response. Stress hormone monitoring may assist further improvements in surgical technique.


bupivacaine

tramadol

Preemptive peritonsillar infiltration with bupivacaine in combination with tramadol improves pediatric post-tonsillectomy pain better than using bupivacaine or tramadol alone: A randomized, placebo-controlled, double blind clinical trial. Post-tonsillectomy pain is one of the most common problems after anesthesia, therefore use of a good anesthesia technique with minimum side effect is an important aim. This study was performed to compare the efficacy of peritonsillar infiltration of bupivacaine , tramadol and combination of bupivacaine-tramadol in post-tonsillectomy pain . ### Materials And Methods In a double blind trial 120 ASA I and II children condidated for tonsillectomy were randomized into four groups: Peritonsillar infiltration with bupivacaine 1 mg/kg in Group B, tramadol 2 mg/kg in Group T, combination of bupivacaine-tramadol in Group BT and saline in Group C was done. ### results Until 60 minutes in the recovery room, control of pain in the first three groups were better than Group C (P < 0.05) and in the third group it was better than others. Four hours after surgery, control of pain was better in the second and third groups in comparison to Groups B and Group C (P <0.05) and was better in the third group in comparison to the second group. Then, 24 hours after that, only in the group III the control of pain was effective (P < 0.05). ### conclusions In this study we showed that peritonsillar infiltration with combination of bupivacain-tramadol provided less post surgery pain compared with infiltration of bupivacaine and tramadol alone in adenotonsillectomy of children.


bleomycin

mitomycin

Concomitant radiotherapy with mitomycin C and bleomycin compared with radiotherapy alone in inoperable head and neck cancer: final report. To compare the efficacy of concomitant irradiation with mitomycin C and bleomycin in patients with inoperable head and neck carcinoma with radiotherapy alone. ### Methods And Materials Between March 1991 and December 1993, 64 patients with inoperable head and neck carcinoma (41 with oropharyngeal site) were randomized to radiotherapy alone (group A) or radiotherapy combined with simultaneous application of mitomycin C and bleomycin (group B). In both groups patients were irradiated five times weekly with 2 Gy to a total dose of 66-70 Gy. The planned concomitant treatment in group B was : bleomycin 5 units twice a week i.m . , total dose 70 units , mitomycin C 15 mg/m2 i.v . after delivery of 10 Gy , and 10 mg/m2 i.v . on the last day of radiotherapy . To enhance the effect of these two drugs, patients received also nicotinamide, chlorpromazine, and dicoumarol. Because significantly better results were achieved in arm B for patients with inoperable oropharyngeal carcinoma, the study was closed and such patients were after December 1993 routinely treated with the combined therapy (as in arm B). Until October 1996, we treated and followed up 48 such consecutive patients. ### results Median follow-up of our study patients is 42 months. Complete remission (CR) rate in group A was 31% and in group B 59% (p = 0.04); disease-free survival (DFS) in group A was 8% and in group B 37% (P = 0.01); and overall survival (OS) was 7% in group A and 26% in group B (p = 0.08). CR rate for patients with oropharyngeal carcinoma was 29% in group A (N = 21) and 75% in group B (N = 20) (p = 0.007); DFS in group A was 10% and in group B 48% (p = 0.001); and the OS was 10% in group A and 38% in group B (p = 0.019). In patients with inoperable oropharyngeal carcinoma treated after December 1993, complete remission was achieved in 32/48 (67%, 95% CI: 52%-80%). DFS at the median follow-up of 14 months was 60% (95% CI 43-77%) and OS 58% (95% CI 42-74%). ### conclusion From the results of our study it seems that the concomitant treatment significantly improves CR rate, DFS, and OS in patients with inoperable oropharyngeal carcinoma in comparison with radiotherapy alone.


dulanermin

bevacizumab

A phase 1B study of dulanermin in combination with modified FOLFOX6 plus bevacizumab in patients with metastatic colorectal cancer.  The study objectives were to evaluate the safety , tolerability , and preliminary efficacy of multiple doses of dulanermin in combination with modified FOLFOX6 and bevacizumab in previously untreated patients with locally advanced , recurrent , or metastatic colorectal cancer . ### Patients And Methods A total of 23 patients received dulanermin at dosages of 4.5 or 9 mg/kg/d given on days 1 to 3 of each 14-day cycle along with standard dosing of modified FOLFOX6 plus bevacizumab. Dose-limiting toxicities, adverse events (AEs), maximum tolerated dose, and response according to Response Evaluation Criteria in Solid Tumors were assessed. ### results In the first cohort (3 patients given dulanermin at 4.5 mg/kg/d) and second cohort (6 patients given dulanermin at 9 mg/kg/day), no dose-limiting toxicities were observed. The subsequent 14 patients were treated with a dulanermin dosage of 9 mg/kg/d. Patients (N = 23) received 2 to 42 cycles of dulanermin (median 15). The most common grade 3 or 4 AEs were neutropenia (39%), hypertension (17%), peripheral neuropathy (17%), hand-foot syndrome (13%), and pulmonary embolism (13%). Three patients (13%) discontinued the study because of serious AEs. Overall, a best response of partial response was observed in 13 patients (57%) (9 confirmed, 4 unconfirmed), stable disease was observed in 7 patients (30%), and disease progression was observed in 3 patients (13%). The median progression-free survival was 9.9 months (95% confidence interval, 7.0-12.7). ### conclusions Overall, the addition of dulanermin to first-line FOLFOX plus bevacizumab was well tolerated in patients with advanced colorectal cancer, with similar AEs that would be expected from FOLFOX plus bevacizumab. A randomized study is required to assess the clinical efficacy of dulanermin in this patient population.


formoterol

salmeterol

[A comparison of inhalatory beta2-mimetics with long-term action (formoterol vs. salmeterol)]. Asthma is a serious global health problem. People of all age groups in all countries of the world suffer from this chronic disease of the respiratory tract, which may have a very serious and sometimes fatal course. Most beta2-mimetics with a rapid onset of effect act for 4 to 6 hours. Inhalatory beta2-mimetics with long-term action ( LABA ) , formoterol and salmeterol , possess a period of action longer than 12 hours . formoterol and salmeterol represent great progress in asthma management, particularly in combination with inhalatory corticosteroids (IKS). Their effective bronchodilatory properties and long-term improvement of pulmonary functions are a great clinical contribution for the patients. Both formoterol and salmeterol are strong and effective beta2-agonists, but their different chemical structures produce different pharmacological properties. Due to the fact that the onset of the effect of salmeterol is slower, it should not be used to treat acute symptoms or quickly deteriorating asthma. formoterol exerts a rapid onset of the effect and high internal activity, thanks to which it can be used for relieving treatment. The present paper aims to characterize and compare the properties of long-term acting beta2-mimetics, with detailed focus on their two representatives, formoterol and salmeterol.


amlodipine

lisinopril

allopurinol

Effect of amlodipine, lisinopril and allopurinol on acetaminophen-induced hepatotoxicity in rats. Exposure to chemotherapeutic agents such as acetaminophen may lead to serious liver injury. Calcium deregulation, angiotensin II production and xanthine oxidase activity are suggested to play mechanistic roles in such injury. ### objective This study evaluates the possible protective effects of the calcium channel blocker amlodipine , the angiotensin converting enzyme inhibitor lisinopril , and the xanthine oxidase inhibitor allopurinol against experimental acetaminophen-induced hepatotoxicity , aiming to understand its underlying hepatotoxic mechanisms . ### Material And Methods Animals were allocated into a normal control group, a acetaminophen hepatotoxicity control group (receiving a single oral dose of acetaminophen; 750 mg/kg/day), and four treatment groups receive N-acetylcysteine (300 mg/kg/day; a reference standard), amlodipine (10 mg/kg/day), lisinopril (20 mg/kg/day) and allopurinol (50 mg/kg/day) orally for 14 consecutive days prior to acetaminophen administration. Evaluation of hepatotoxicity was performed by the assessment of hepatocyte integrity markers (serum transaminases), oxidative stress markers (hepatic malondialdehyde, glutathione and catalase), and inflammatory markers (hepatic myeloperoxidase and nitrate/nitrite), in addition to a histopathological study. ### results Rats pre-treated with amlodipine, lisinopril or allopurinol showed significantly lower serum transaminases, significantly lower hepatic malondialdehyde, myeloperoxidase and nitrate/nitrite, as well as significantly higher hepatic glutathione and catalase levels, compared with acetaminophen control rats. Serum transaminases were normalized in the lisinopril treatment group, while hepatic myeloperoxidase was normalized in the all treatment groups. Histopathological evaluation strongly supported the results of biochemical estimations. ### conclusion amlodipine, lisinopril or allopurinol can protect against acetaminophen-induced hepatotoxicity, showing mechanistic roles of calcium channels, angiotensin converting enzyme and xanthine oxidase enzyme in the pathogenesis of hepatotoxicity induced by acetaminophen.


cyclophosphamide

methotrexate

fluorouracil

Adjuvant cyclophosphamide, methotrexate and fluorouracil in node-negative and estrogen receptor-negative breast cancer. Updated results. Node-negative breast cancers are considered to comprise a subgroup which is amenable to cure with local-regional therapy alone. However, approximately 30% of affected patients present new disease manifestations within 10 years after surgery. To test the hypothesis that node-negative and estrogen receptor-negative breast cancer patients can benefit from adjuvant chemotherapy, a prospective randomized study was activated at the Istituto Nazionale Tumori of Milan in 1980. ### Patients And Methods The study was conducted in 90 patients operated on for unilateral breast cancer who were then assigned to receive either 12 intravenous cycles of cyclophosphamide , methotrexate and fluorouracil ( CMF ) every three weeks , or no further treatment . Adjuvant chemotherapy was administered in the outpatient clinic of the Division of Medical Oncology. Patient characteristics were fairly well balanced between the two treatment groups except for primary tumor size: 58% of those with a primary tumor measuring > 2 cm in its largest diameter were randomized in the control group compared with 38% in the CMF regimen (P = 0.06). ### results At 12 years after surgery treatment outcome was significantly superior for patients given adjuvant CMF. The relapse-free survival rate was 71% (95% confidence limits (CL): 56-86) versus 43% (95% CL: 28-58), and total survival was 80% (95% CL: 68-92) versus 50% (95% CL: 34-66), respectively. The benefit from the administration of CMF was evident in all patient subsets and was not influenced by menopausal status. ### conclusions The long-term results of this trial of adjuvant combination chemotherapy confirm our previous observations on the efficacy of adjuvant chemotherapy in node-negative breast cancer patients at high risk of early disease relapse.


emedastine

loratadine

A randomized, double-blind, placebo-controlled comparison of emedastine 0.05% ophthalmic solution with loratadine 10 mg and their combination in the human conjunctival allergen challenge model. When selecting treatment for allergic conjunctivitis, a primary concern is whether to choose local or systemic therapy. ### objective This study compared the efficacy of topical emedastine 0.05 % ophthalmic solution with that of oral loratadine 10 mg and their combination in the conjunctival allergen challenge model of allergic conjunctivitis . ### methods This was a single-center, randomized, double-masked, placebo-controlled, parallel-group study. At visit 1, eligible subjects underwent conjunctival allergen challenge to identify the dose required to elicit a positive allergic reaction. After 7 days, subjects returned for visit 2, at which the allergen dose was confirmed. At visit 3, which took place 2 weeks later, subjects were randomized to receive either emedastine plus placebo capsules, loratadine plus placebo eyedrops, or both emedastine and loratadine. One hour after receiving study drug, subjects were challenged with allergen in both eyes. Allergic signs and symptoms were graded using standardized 5-point scales. The primary efficacy variables were itching and conjunctival hyperemia. Secondary efficacy variables were ciliary and episcleral hyperemia, chemosis, lid swelling, and tearing. Itching was graded subjectively at 3, 5, and 10 minutes after challenge. All other variables were assessed at 5, 10, and 20 minutes after challenge. ### results Eighty subjects (mean age, 43.68 years) were randomized to receive study treatment. Forty subjects (20 men, 20 women) received emedastine plus placebo capsules, 20 (7 men, 13 women) received loratadine plus placebo eyedrops, and 20 (12 men, 8 women) received both active treatments. In the between-group efficacy comparison at visit 3, the difference in itching and hyperemia scores between emedastine and loratadine was statistically significant at all time points (all, P < 0.05). Efficacy scores for the combination of emedastine and loratadine were significantly better than those for loratadine alone at 2 of 3 time points for itching and all time points for hyperemia (P < 0.05). The combination was significantly better than emedastine alone at I of 3 time points for itching and 6 of 9 time points for hyperemia (P < 0.05). ### conclusion In this study, emedastine was more efficacious than loratadine for reducing the itching and redness associated with allergic conjunctivitis in the human conjunctival allergen challenge model.


Erythromycin

clindamycin

carbenicillin

Recontamination after gastrointestinal decontamination with non-absorbable antibiotics. In an attempt to restore the colonization resistance we administered anaerobic microflora to prevent an abnormal colonization of the intestine after antibiotic treatment had been discontinued. After the antibiotics had been discontinued and before the donor flora had been administered and had colonized the intestine, microorganisms present were "unopposed" and expanded to a high density. A mouse model was used to investigate which antibiotics negatively influenced the donor flora and reduced the colonization resistance when administered intraperitoneally. Erythromycin , clindamycin and carbenicillin suppressed the donor flora permanently , as could be seen by the reduced colonization resistance . benzylpenicillin, ampicillin, doxycycline and the combination gentamicin-cephalothin affected the colonization resistance as long as these agents were present. gentamicin alone and cephalothin and oxytetracycline had no effect on the colonization resistance.


Mycophenolate

nivolumab

ipilimumab

Successful mycophenolate mofetil treatment of a patient with severe steroid-refractory hepatitis evoked by nivolumab plus ipilimumab treatment for relapsed bladder cancer.  Mycophenolate mofetil resulted in rapid improvement of steroid-refractory immune-related adverse event hepatitis , induced by nivolumab plus ipilimumab .


saquinavir

indinavir

Synthesis and in vitro biological evaluation of mannose-containing prodrugs derived from clinically used HIV-protease inhibitors with improved transepithelial transport. In an approach to improve the pharmacological properties, safety and pharmacokinetic profiles, and their penetration into HIV reservoirs or sanctuaries, and consequently, the therapeutic potential of the current protease inhibitors (PIs) used in clinics, we investigated the synthesis of various mannose-substituted saquinavir, nelfinavir, and indinavir prodrugs, their in vitro stability with respect to hydrolysis, anti-HIV activity, cytotoxicity, and permeation through a monolayer of Caco-2 cells used as a model of the intestinal barrier. Mannose-derived conjugates were prepared in two steps, in good yields, by condensing an acid derivative of a protected mannose with the PIs, followed by deprotection of the sugar protecting group. With respect to hydrolysis, these PI prodrugs are chemically stable with half-life times in the 50-60 h range that are compatible with an in vivo utilization aimed at improving the absorption/penetration or accumulation of the prodrug in specific cells/tissues and liberation of the active free drug inside HIV-infected cells. These stabilities correlate closely with the low in vitro anti-HIV activity measured for those prodrugs wherein the coupling of mannose to the PIs was performed through the peptidomimetic PI's hydroxyl. Importantly, mannose conjugation to the PIs was further found to improve the absorptive transepithelial transport of saquinavir and indinavir but not of nelfinavir across Caco-2 cell monolayers, by contrast to glucose conjugation which had the opposite effect. The mannose-linked prodrugs of saquinavir and indinavir display therefore a most promising therapeutic potential provided that bioavailability , penetration into the HIV infected macrophages , and HIV-reservoirs of these PIs are improved .


nevirapine

zidovudine

Nevirapine resistance mutations of human immunodeficiency virus type 1 selected during therapy. Drug susceptibility and mutations in the reverse transcriptase (RT) gene were analyzed with 167 virus isolates from 38 patients treated with nevirapine, a potent nonnucleoside inhibitor of human immunodeficiency virus type 1 (HIV-1) RT. Resistant isolates emerged quickly and uniformly in all patients administered nevirapine either as monotherapy or in combination with zidovudine ( AZT ) . Resistance developed as early as 1 week, indicating rapid turnover of the virus population. The development of resistance was associated with the loss of antiviral drug activity as measured by CD4 lymphocyte counts and levels of HIV p24 antigen and RNA in serum. In addition to mutations at amino acid residues 103, 106, and 181 that had been identified by selection in cell culture, mutations at residues 108, 188, and 190 were also found in the patient isolates. Sequences from patient clones documented cocirculating mixtures of populations of different mutants. The most common mutation with monotherapy, tyrosine to cysteine at residue 181, was prevented from emerging by coadministration of AZT, which resulted in the selection of alternative mutations. The observations documented that, under selective drug pressure, the circulating virus population can change rapidly, and many alternative mutants can emerge, often in complex mixtures. The addition of a second RT inhibitor, AZT, significantly altered the pattern of mutations in the circulating population of HIV.


cisplatin

bleomycin

etoposide

Huge retroperitoneal germinoma presenting with pathological fracture of the spine. Primary retroperitoneal germ cell tumors are extremely rare neoplasms. The most common presenting features are abdominal pain and palpable abdominal masses. Pathological fractures of the spine presenting as bilateral lower leg weakness are exceptionally rare. We describe a 16-year-old girl who developed progressive paraplegia after a minor falling injury. Radiological study demonstrated a huge retroperitoneal tumor with invasion of the T12 vertebral body and spinal canal. A posterior surgical approach was used to perform laminectomy (T12, L1), removal of the intraspinal tumor and internal fixation with transpedical screws (T10, T11 to L2,3), and posterolateral fusion. Postoperative combination chemotherapy for six cycles with cisplatin ( 100 mg/m2 per day for 1 day every 3 weeks ) , bleomycin ( 15 units intravenously weekly for 18 weeks ) and etoposide ( 100 mg/m2 per day for 3 days every 3 weeks ) were given and the tumor responded dramatically . The patient had fully recovered without evidence of sequelae or recurrence at 2 years after operation. To the authors' knowledge, this is the first case in which a huge retroperitoneal germinoma presented as pathological fracture of the spine and spinal cord compression. The effectiveness of the postoperative cisplatin-based chemotherapy against this tumor made major retroperitoneal surgery to remove the main tumor mass unnecessary is also demonstrated.


prednisone

vincristine

cytarabine

L-asparaginase

methotrexate

dexamethasone

[Renal tubular acidosis as an initial manifestation in children with malignant lymphoma]. Primary renal lymphoma is one of the malignant lymphomas that initially presents in the extra lymphonode, which is rarely seen in children. This study reported two cases of primary renal lymphoma in children who were definitively diagnosed by renal biopsy. Renal tubular acidosis was the initial manifestation in both cases. They were referred to the hospital with chief complaints of polydipsia, polyuria, debilitation, vomiting and anemia. Imaging and laboratory examinations showed bilateral renomegaly, hypocalcemia, hypophosphatemia, and metabolic acidosis. One of the patients discontinued therapy. The other received chemotherapy including prednisone , vincristine , cytarabine and L-asparaginase , combined with intrathecal injections of methotrexate , dexamethasone and Ara-C and supporting treatment . Twenty-three days after treatment, polydipsia and polyuria were relieved, and acidosis, kaliopenia and anemia were improved in the patient. There were no abnormal findings in the renal B-ultrasound re-examination. It was concluded that when a patient is suspected of renal lymphoma, diagnostic puncture and renal biopsy should be performed early. Early combined therapeutics including chemotherapy, radiation therapy, surgery and supporting treatments may result in a favorable prognosis in patients with this disease.


oxaliplatin

irinotecan

leucovorin

A pathological complete response after neoadjuvant triplet chemotherapy for locally advanced transverse colon cancer. Perioperative chemotherapy could improve oncological outcomes for patients with advanced colon cancer. However, the effectiveness of triplet chemotherapy in the neoadjuvant setting is still unknown. ### Presentation Of Case A 61-year-old man was referred to our hospital due to abdominal distention. Abdominal computed tomography showed a huge, 18-cm mass in the right upper abdomen. Biopsy showed well-differentiated adenocarcinoma. Locally advanced transverse colon cancer T4b N2a M0 Stage IIIC was diagnosed. Considering the extensive invasion to surrounding organs and difficulties in achieving margin-negative surgery, an emergency ileostomy was performed first. Then , neoadjuvant chemotherapy ( NAC ) consisting of a combination of 5-fluorouracil ( 5-FU ) , oxaliplatin , irinotecan , and leucovorin ( FOLFOXIRI ) was planned , followed by primary tumor resection . After 6 courses of treatment, the primary tumor shrank remarkably. Finally, laparoscopic radical extended right hemi-colectomy was performed. There were no residual tumor cells in resected specimens, including the primary tumor and surrounding lymph nodes. The pathological diagnosis was complete response. ### conclusion A case of pathological complete response after neoadjuvant treatment followed by radical resection was reported. Further research is needed to confirm the appropriate indications for neoadjuvant FOLFOXIRI therapy for patients with LACC.


aspirin

docetaxel

vinorelbine

Aspirin attenuates YAP and β-catenin expression by promoting β-TrCP to overcome docetaxel and vinorelbine resistance in triple-negative breast cancer. The use of aspirin has been associated with reduced breast cancer risk, but it is litter known if aspirin overcomes chemoresistance in triple-negative breast cancer (TNBC). Herein, we demonstrated that changes in the expression of Yes-associated protein (YAP) and β-catenin might be a promising predictive biomarker for neoadjuvant chemotherapy sensitivity in TNBC patients. Inhibition of YAP or β-catenin enhanced the cytotoxicity of the anti-microtubule agents docetaxel and vinorelbine against drug-resistant TNBC cells as well as the sensitivity of these cells to the agents in vitro and in vivo. Interestingly , aspirin not only significantly inhibited the growth of TNBC cells , but also attenuated YAP and β-catenin expression by upregulating the E3 ubiquitin ligase β-TrCP to abolished docetaxel and vinorelbine resistance . The combination of aspirin and docetaxel or vinorelbine remarkably inhibited the growth of drug-resistant TNBC cells in vitro and in vivo. Moreover, TNBC patients with high YAP and/or β-catenin expression had a higher risk of relapse or mortality than patients with low YAP and/or β-catenin expression. Collectively, our study discovered a novel role of aspirin based on its anticancer effect, and put forward some possible mechanisms of chemoresistance in TNBC. The combined use of aspirin and anti-microtubule drugs presented several promising therapeutic approaches for TNBC treatment.


paclitaxel

doxorubicin

Combination paclitaxel (Taxol) and doxorubicin therapy for metastatic breast cancer. paclitaxel (Taxol; Bristol-Myers Squibb Company, Princeton, NJ) is a very active agent for the treatment of breast cancer, with associated complete response rates of 12% in patients with minimally pretreated metastatic disease. Simultaneous paclitaxel and doxorubicin administration by 72-hour continuous infusion in patients with previously untreated metastatic breast cancer has yielded an overall response rate of 72% with 8% complete responses. No alterations in paclitaxel or doxorubicin pharmacokinetics were observed when the drugs were administered alone versus in combination . Two phase I studies from the M.D. Anderson Cancer Center (Houston, TX) and the University of Indiana (Indianapolis, IN) have shown that administration of a 24-hour paclitaxel infusion prior to doxorubicin results in a significantly higher incidence of mucositis than the reverse sequence. Preliminary pharmacokinetic studies from M.D. Anderson suggest that peak plasma concentration and clearance of doxorubicin are altered by pretreatment with 24-hour paclitaxel. In contrast, in an ongoing phase I study at the Istituto Nazionale Tumori in Milan, Italy, no differences in toxicities have been observed with the combination of intravenous bolus doxorubicin and 3-hour infusional paclitaxel administered by either sequence. Preclinical in vitro and in vivo studies suggest that the combination of paclitaxel and doxorubicin is associated with no or minimal additive antitumor effects. The modest complete response rates that have been observed in patients with metastatic breast cancer to date are in agreement with these observations. A randomized study of paclitaxel versus doxorubicin versus intravenous bolus doxorubicin followed by 24-hour paclitaxel is now being conducted by the Eastern Cooperative Oncology Group.

etoposide

Outcome of relapse in children and adolescents with B-cell non-Hodgkin lymphoma and mature acute leukemia: A report from the French LMB study. In order to describe relapsed B-cell non-Hodgkin lymphoma and mature acute leukemia in children/adolescents treated with the Lymphomes Malins B (LMB) regimen and their outcome in the rituximab era, relapses in the French LMB2001 study were reviewed. ### methods Between February 2001 and December 2011, 33 patients out of 773 (4.3%) relapsed; 27 had Burkitt lymphoma and six large B-cell histology. Median age at diagnosis was 10.1 years. One patient was initially treated in risk group A, 21 in group B, and 11 in group C. ### results Median time to relapse after diagnosis was 4.5 months (range 2.4-13.6). Thirty-two patients received salvage therapy. Twenty-seven received rituximab mainly in addition to high-dose cytarabine and etoposide ( n = 18 ) and/or ifosfamide , carboplatin , and etoposide ( n = 7 ) . First-line salvage chemotherapy response rate was 66% with 47% being complete remission (CR). Twenty-one patients received high-dose chemotherapy (HDC) followed by autologous (n = 13) or allogeneic (n = 8) transplant. With a median follow-up of 6.8 years, the 5-year survival rate after relapse was 36.4% (95% confidence interval [CI] 22-53%). Twelve patients were still alive; all but one (group A) received consolidation treatment. Achieving CR before consolidation was significantly associated with better survival, with a 5-year survival rate of 75% (95% CI 46.8-91.1%) for patients in CR before HDC, 33% (95% CI 9.7-70%) for patients in partial remission, and 0% for nonresponders (P = .033). ### conclusion Survival of children/adolescents with mature B-cell lymphoma/leukemia remains poor after relapse with no apparent improvement with rituximab. Response rates to salvage chemo-immunotherapies are insufficient and new drugs are urgently needed to improve disease control.


simvastatin

rosuvastatin

Comparison of the effect of simvastatin versus simvastatin/ezetimibe versus rosuvastatin on markers of inflammation and oxidative stress in subjects with hypercholesterolemia. Statins may exhibit anti-inflammatory and antioxidant effects. Whether different statins at equivalent doses or the combination of low-dose statin with ezetimibe have comparable anti-inflammatory and antioxidant effects is unknown. The aim of this study was to compare the effects of simvastatin, simvastatin/ezetimibe or rosuvastatin at equivalent low-density lipoprotein cholesterol lowering doses on inflammation and oxidative stress indices in subjects with hypercholesterolemia. ### methods This was a pre-specified analysis of a prospective, randomized, open-label, blinded endpoint (PROBE) study. We enrolled one hundred and fifty three (n = 153) hypercholesterolemic subjects who were randomized to receive simvastatin 40 mg or simvastatin/ezetimibe 10/10 mg or rosuvastatin 10 mg daily. Plasma 8-Epi prostaglandin F2 alpha (8-epiPGF2a), oxidized LDL (oxLDL) and lipoprotein-associated phospholipase A2 (Lp-PLA2) activity and mass were measured at baseline and following 12 weeks of treatment. ### results A significant reduction in plasma 8-isoprostane and oxLDL levels was observed in all treatment groups [ by 10 % , 8 % and 6 % ( p < 0.05 compared with baseline ) and 41 % , 40 % and 39 % ( p < 0.001 compared with baseline ) in simvastatin , simvastatin/ezetimibe and rosuvastatin groups , respectively ] . In all treatment groups a significant reduction in total plasma Lp-PLA2 activity and mass was observed (by 36%, 31% and 38% and 36%, 32% and 32% for simvastatin, simvastatin/ezetimibe and rosuvastatin, respectively, p < 0.001 compared with baseline). No intergroup differences were observed. ### conclusions simvastatin 40 mg, simvastatin/ezetimibe 10/10 mg and rosuvastatin 10 mg significantly reduced 8-epiPGF2a, oxLDL and Lp-PLA2 activity and mass to a similar extent.


verapamil

trandolapril

Efficacy of combination therapy with trandolapril and verapamil sr in primary hypertension: a 4 x 4 trial design. The Trandolapril Study Group. The Joint National Committee V suggested that combination therapy can provide effective blood pressure control in patients with stage I-IV hypertension. This 4 x 4 factorial trial design assessed the efficacy of monotherapy with trandolapril-an ACE inhibitor, and verapamil SR-a calcium antagonist, each in a range of 3 doses as monotherapy, and in combination therapy in patients with stage I-III diastolic hypertension. After a 4-week, single-blind placebo treatment period, 746 patients in 39 study centers were randomized to 1 of the 16 double-blind treatments for 6 weeks (placebo, verapamil SR monotherapy 120, 180, or 240 mg; trandolapril monotherapy 0.5, 2, or 8 mg; and trandolapril/verapamil SR combinations 0.5/120, 0.5/180, 0.5/240, 2/120, 2/180, 2/240, 8/120, 8/180, or 8/240 mg. Both mono and combination therapies achieved the primary efficacy parameters : lowered diastolic blood pressure ( at trough ) more than placebo , p < 01 ( except the 120 mg verapamil SR , NS , 0.5 mg trandolapril , 0.5/180 and 2/120 combinations , p < 05 ) , yielded a trough to peak ratio of > 0.52 and had higher percentages of responders compared to placebo . Combination therapy was more effective than monotherapy for sitting diastolic blood pressure 2/180, p < 01; 2/240 and 8/240, p < 05. There were no differences between active treatment groups and placebo as a percentage of patients having adverse reactions. trandolapril, 2 and 8 mg, appeared to have a greater incremental effect on the systolic blood pressure reduction of the combination than verapamil SR 180 and 240 mg.


gemcitabine

methotrexate

vinblastine

doxorubicin

cisplatin

[Neoadjuvant or Adjuvant Chemotherapy for Bladder Cancer?]. Advanced urothelial carcinoma of the bladder is associated with a high metastatic potential. Life expectancy for metastatic patients is poor and rarely exceeds more than one year without further therapy. Neoadjuvant chemotherapy can decrease the tumour burden while reducing the risk of death. Adjuvant chemotherapy has been discussed controversially. Patients with lymph node-positive metastases seem to benefit the most from adjuvant chemotherapy. In selected patients, metastasectomy can prolong survival. In metastastic patients , the combination of gemcitabine and cisplatin has become the new standard regimen due to a lower toxicity in comparison to the combination of methotrexate , vinblastine , doxorubicin , and cisplatin ( MVAC ) . For second-line treatment, vinflunine is the only approved therapeutic agent.


ceritinib

alectinib

ALK inhibitors in non-small cell lung cancer: crizotinib and beyond. The treatment of patients with advanced non-small cell lung cancer (NSCLC) harboring chromosomal rearrangements of anaplastic lymphoma kinase (ALK) has been revolutionized by the development of crizotinib, a small molecule inhibitor of the tyrosine kinases ALK, ROS1, and MET. Resistance to crizotinib invariably develops, however, through a variety of mechanisms. In the last few years , a flurry of new and more potent ALK inhibitors has emerged for the treatment of ALK-positive NSCLC , including ceritinib ( LDK378 ) , alectinib ( RO5424802/CH5424802 ) , AP26113 , ASP3026 , TSR-011 , PF-06463922 , RXDX-101 , X-396 , and CEP-37440 . Cancers harboring ALK rearrangements may also be susceptible to treatment with heat shock protein 90 inhibitors. This review focuses on the pharmacologic and clinical properties of these compounds, either as monotherapies or in combination with other drugs. With so many ALK inhibitors in development, the challenges of how these agents should be studied and ultimately prescribed are also discussed.


doxorubicin

ifosfamide

cisplatin

A randomized clinical trial of adjuvant chemotherapy with doxorubicin , ifosfamide , and cisplatin followed by radiotherapy versus radiotherapy alone in patients with localized uterine sarcomas ( SARCGYN study ) . There is no proven benefit of adjuvant treatment of uterine sarcoma (US). SARCGYN phase III study compared adjuvant polychemotherapy followed by pelvic radiotherapy (RT) (arm A) versus RT alone (arm B) conducted to detect an increase ≥ 20% of 3-year PFS. ### methods Patients with FIGO stage ≤ III US, physiological age ≤ 65 years; chemotherapy: four cycles of doxorubicin 50 mg/m² d1, ifosfamide 3 g/m²/day d1-2, cisplatin 75 mg/m² d3, (API) + G-CSF q 3 weeks. Study was stopped because of lack of recruitment. ### results Eighty-one patients were included: 39 in arm A and 42 in arm B; 52 stage I, 16 stage II, 13 stage III; 53 leiomyosarcomas, 9 undifferenciated sarcomas, 19 carcinosarcomas. Gr 3-4 toxicity during API (/37 patients): thrombopenia (76%), febrile neutropenia (22%) with two toxic deaths; renal gr 3 (1 patient). After a median follow-up of 4.3 years, 41/81 patients recurred, 15 in arm A, 26 in arm B. The 3 years DFS is 55% in arm A, 41% in arm B (P = 0.048). The 3-year overall survival (OS) is 81% in arm A and 69% in arm B (P = 0.41). ### conclusion API adjuvant CT statistically increases the 3 year-DFS of patients with US.


irinotecan

leucovorin

Pharmacodynamic study of the Saltz regimen for metastatic colorectal cancer in a hemodialyzed patient.  Combination therapy with irinotecan ( CPT-11 ) , 5-fluorouracil ( 5-FU ) and leucovorin is widely used for the treatment of metastatic colorectal cancer . However, little is known about the safety of chemotherapy of malignancies in hemodialysis (HD) patients. We encountered a patient with colorectal carcinoma on HD. We decided to administer combination chemotherapy while monitoring the pharmacodynamics of the patient. ### Case Report A 74-year-old male received regular HD 3 times a week because of type 1 diabetes mellitus. He was diagnosed with stage IV colorectal cancer in November 2004. After sigmoidectomy, the patient received chemotherapy: a weekly schedule of CPT-11 (50 mg/m(2)) was administered followed by l-leucovorin (10 mg/m(2)) and 5-FU (400 mg/m(2)) just after HD. During the course, the plasma concentrations of both SN-38, an active metabolite of CPT-11, and 5-FU were not increased compared with those of patients with normal renal function. Our patient presented with grade III hematological toxicity that was easily recovered by granulocyte colony-stimulating factor. ### conclusion These data suggest that the dose-reduced Saltz regimen can be feasible for colorectal cancer patients receiving dialysis as postoperative adjuvant chemotherapy.


fludarabine

cyclophosphamide

mitoxantrone

Long-term safety and outcome of fludarabine , cyclophosphamide and mitoxantrone ( FCM ) regimen in previously untreated patients with advanced follicular lymphoma : 12 years follow-up of a phase 2 trial . fludarabine combinations are very affective in follicular lymphoma (FL) with high rates of complete response and prolonged survival. However, late toxicities could be a concern. The aim of the present study was to analyze the long-term impact on survival, relapse and late toxicities of a trial of treatment with fludarabine, mitoxantrone and cyclophosphamide (FCM regimen) for untreated patients with advanced stage FL. One hundred and twenty patients enrolled in a phase 2 trial of treatment with FCM regimen between 2000 and 2003 were evaluated. After a median follow-up of 12 years, 52 patients eventually relapsed/progressed with 10 year progression-free survival (PFS) of 46 %. Ten patients showed histological transformation to aggressive lymphoma with a risk of transformation of 2 and 9 % at 5 and 10 years, respectively. Three patients developed therapy-related myelodysplastic syndrome/acute myeloid leukaemia (MDS/AML) and seven solid neoplasms with an overall risk of 3 and 8 % at 5 and 10 years, respectively. Twenty-six patients eventually died during the follow-up. Overall survival at 10 years was 83 %. In conclusion, FCM regimen allows excellent long-lasting response in previously untreated patients with FL. The incidence of late events including histological transformation and secondary neoplasia is low but not negligible.
