Adverse events were analysed in the safety population in which hydroxychloroquine recipients were participants who received at least one dose of hydroxychloroquine and hydroxychloroquine non-recipients were those managed with standard of care alone.\n\nOutcome\n\nThe primary outcomes for this trial were whether patients had negative conversion of SARS-CoV-2 by 28 days and whether patients with severe covid-19 had clinical improvement by 28 days. However, as the trial was stopped early and only two patients with severe disease were enrolled, results on clinical improvement are not presented. We defined negative conversion of SARS-CoV-2 as two consecutive reports of a negative result for SARS-CoV-2 at least 24 hours apart without a subsequent report of a positive result by the end of the study. We considered the date of the first negative report as the date of negative conversion. In the original protocol, the primary endpoint was prespecified as the “Negative conversion rate by Day 10” (approved by the ethics committee on 6 February 2020). However, with the increasing knowledge of covid-19 from our clinical practice, we realised that the duration of SARS-CoV-2 in respiratory samples of many patients was longer than 10 days, recently highlighted by a detailed virological study.14 We therefore modified our primary outcome to test whether patients had a negative conversion of SARS-CoV-2 by 28 days (approved by the ethics committee on 17 February 2020). Probability of negative conversion at day 4, 7, 10, 14, or 21 was specified as a secondary outcome in the protocol, but this does not appear on the trial registration list. The listed secondary outcome in the trial registration was adverse events coded using the latest version of Medical Dictionary for Regulatory Activities coding dictionary, recorded in standard medical terminology and graded according to the National Cancer Institute Common Terminology Criteria for Adverse Events.\n\nOther prespecified secondary outcomes not listed in the trial registration but included in the protocol were the probabilities of alleviation of clinical symptoms; improvement of C reactive protein, erythrocyte sedimentation rate, tumour necrosis factor α, interleukin 6, and absolute blood lymphocyte count; improvement of lung lesions on chest radiology; all cause death; and disease progression in patients with mild to moderate disease. The time frame for these secondary outcomes was from randomisation to 28 days. Prespecified secondary outcomes for patients with severe disease are not listed here but are included in the protocol. Owing to the early termination of our study, we could not justify the results from these analyses with an underpowered sample size and therefore decided not to emphasise them in this paper to avoid misinterpretation. The only one presented here is the alleviation of clinical symptoms within 28 days, which is an important outcome of interest prespecified in our protocol. The definition of the alleviation of clinical symptoms was resolving from fever to an axillary temperature of 36.6°C or below, normalisation of SpO2 (>94% on room air), and disappearance of

The COVID-19 pandemic is showing an exponential growth, mandating an urgent need to develop an effective treatment. Indeed, to date, a well-established therapy is still lacking. We aimed to evaluate the safety and efficacy of hydroxychloroquine (HCQ) added to standard care in patients with COVID-19. This was a multicenter, randomized controlled trial conducted at three major university hospitals in Egypt. One hundred ninety-four patients with confirmed diagnosis of COVID-19 were included in the study after signing informed consent. They were equally randomized into two arms: 97 patients administrated HCQ plus standard care (HCQ group) and 97 patients administered only standard care as a control arm (control group). The primary endpoints were recovery within 28 days, need for mechanical ventilation, or death. The two groups were matched for age and gender. There was no significant difference between them regarding any of the baseline characteristics or laboratory parameters. Four patients (4.1%) in the HCQ group and 5 (5.2%) patients in the control group needed mechanical ventilation (P = 0.75). The overall mortality did not differ between the two groups, as six patients (6.2%) died in the HCQ group and 5 (5.2%) died in the control group (P = 0.77). Univariate logistic regression analysis showed that HCQ treatment was not significantly associated with decreased mortality in COVID-19 patients. So, adding HCQ to standard care did not add significant benefit, did not decrease the need for ventilation, and did not reduce mortality rates in COVID-19 patients", "entities": [{"id": "T1", "type": "PrimaryOutcome", "offsets": [[763, 771]], "text": "recovery"}, {"id": "T2", "type": "PrimaryOutcome", "offsets": [[788, 819]], "text": "need for mechanical ventilation"}, {"id": "T3", "type": "PrimaryOutcome", "offsets": [[824, 829]], "text": "death"}, {"id": "T4", "type": "TimeFrame", "offsets": [[772, 786]], "text": "within 28 days"}], "relations": [{"id": "R1", "type": "MeasuredAt", "arg1": "T1", "arg2": "T4"}]} {"id": "13", "type": "gold", "text": "Clinical study\nPatients\nThe study was initially designed as a multi-center study across hospitals in Changsha city and in other cities of Hunan Province,\nChina. However, per a government order, all patients from hospitals in Changsha city had to be relocated to the First Hospital of Changsha, a designated treatment center for all COVID-19 patients in Changsha city, and hospitals in other cities of Hunan\nProvince were not able to participate due to various reasons. The study was changed to a single-center study. This study was approved by the ethics committee of the First Hospital of Changsha (file number KX-2020002) and was conducted at the hospital. The study was also registered in the Chinese Clinical Trial Registry (http://www.chictr.org.cn/), number ChiCTR2000029496.\nHospitalized COVID-19 patients with confirmed SARS-CoV-2 detection, clinically classified as moderate or severe, at an age over 18 years, and without comorbidity of severe heart, lung, or brain diseases, were eligible for enrolling into this study. Moderate patients were defined as “patients with fever, symptoms of the respiratory system and pneumonia changes in CT images, and severe patients were defined as “patients with any of the following: (1) Respiratory distress, respiratory frequency \u0015 30/ min; (2) Under rest status, arterial oxygen saturation (SaO2 ) \u0014 93%; (3) Arterial partial pressure of oxygen (PaO2)/fraction of inspired oxygen (FiO2) \u0014 300 mmHg. In this study, we aimed to observe moderate and severe COVID-19 patients as these patients would likely benefit more from antiviral treatments.\nTrial design and treatments\nThis was a randomized, open-label, parallel-group study.\nPatients eligible for the study were assigned, in a 1:1:1 ratio, to\nNovaferon, Novaferon plus Lopinavir/Ritonavir, or Lopinavir/\nRitonavir group. An SAS generated simple randomization schedule was prepared by a statistician not involved in the trial. Using the order in which they enrolled in the study, patients were assigned to a treatment group that was implemented by a research assistant.\nInformed consent was obtained from all enrolled patients.\nAntiviral effects were assessed on day three, day six, and day nine after starting drug administration.\nThe approved dosage of Novaferon for hepatitis B application is the daily injection of 10 mg of protein in 1.0 ml volume per vial.\nLopinavir/Ritonavir (Kaletra) was manufactured by AbbVie Inc.; each tablet contained 200 mg of Lopinavir and 50 mg of Ritonavir.\nThe total daily doses (40 mg) of Novaferon were administered to patients twice per day by oxygen-driven aerosolized inhalation for 15 min of 20 mg of Novaferon (2 \u0003 1 ml vials) diluted with saline.\nFor patients receiving Lopinavir/Ritonavir (Kaletra), two tablets were orally taken twice per day. The aerosolized inhalation was administrated to hospitalized patients in the negative-pressure wards at the designated COVID-19 center to minimize the risk of disease transmission.\nAssessments\nSamples of nasopharyngeal swabs on day three, day six, and day nine during the seven to ten-day course of antiviral treatment were collected from the patients and tested for SARS-CoV-2 nucleic acids by RT-PCR. SARS-CoV-2 clearance in COVID-19 patients was defined as two consecutive negative-detection of SARS-CoV-2 RNA in nasopharyngeal swab samples with an interval of over 24 h.\nAdverse events were monitored throughout the trial, reported and graded based on the WHO Toxicity Grading Scale for Determining the Severity.\nThe peak levels of the SARS virus were around ten days after onset, and then the viral level began to decrease without effective antiviral treatment in SARS patients (Peiris et al., 2003).\nConsidering the homology of gene sequences of SARS-CoV-2 and SARS was over 90% (Zhu et al., 2020), we assumed that the intervention of antiviral drugs in COVID-19 patients would likely enhance or shorten the time to viral clearance. In this regard, this study's primary endpoint was chosen based on the SARS-CoV-2 clearance rates in COVID-19 patients assessed on day six of antiviral treatment. The secondary endpoint was the median time to SARS-CoV-2 clearance", "entities": [{"id": "T1", "type": "OtherOutcome", "offsets": [[3194, 3235]], "text": "SARS-CoV-2 clearance in COVID-19 patients"}, {"id": "T2", "type": "TimeFrame", "offsets": [[3016, 3051]], "text": "on day three, day six, and day nine"}, {"id": "T3", "type": "OutcomeDefinition", "offsets": [[3251, 3364]], "text": "two consecutive negative-detection of SARS-CoV-2 RNA in nasopharyngeal swab samples with an interval of over 24 h"}, {"id": "T4", "type": "OtherOutcome", "offsets": [[3366, 3380]], "text": "Adverse events"}, {"id": "T5", "type": "OutcomeDefinition", "offsets": [[3418, 3506]], "text": "reported and graded based on the WHO Toxicity Grading Scale for Determining the Severity"}, {"id": "T6", "type": "PrimaryOutcome", "offsets": [[4000, 4027]], "text": "SARS-CoV-2 clearance rates"}, {"id": "T7", "type": "TimeFrame", "offsets": [[4058, 4091]], "text": "on day six of antiviral treatment"}, {"id": "T8", "type": "SecondaryOutcome", "offsets": [[4124, 4159]], "text": "median time to SARS-CoV-2 clearance"}], "relations": [{"id": "R1", "type": "MeasuredAt", "arg1": "T1", "arg2": "T2"}, {"id": "R2", "type": "DefinedAs", "arg1": "T1", "arg2": "T3"}, {"id": "R3", "type": "DefinedAs", "arg1": "T4", "arg2": "T5"}, {"id": "R4", "type": "MeasuredAt", "arg1": "T6", "arg2": "T7"}]} {"id": "14", "type": "gold", "text": "Outcomes\n\nThe primary clinical endpoint was time to clinical improvement within 28 days after randomisation.

Forty-two patients in the interferon group received IFN-1a in addition to the national protocol medications (hydroxychloroquine plus lopinavirritonavir or atazanavir-ritonavir). Each 44g/ml (12 million IU/ml) dose of interferon-1a was subcutaneously injected three times weekly for two consecutive weeks.\nThe control group consisted of 39 patients who received only the national protocol medications. The primary outcome of the study was time to reach clinical response.\nSecondary outcomes were duration of hospital stay, length of intensive care unit stay, 28-day mortality, effect of early or late administration of IFN on mortality, adverse effects, and complications during the hospitalization. Between 29 February and 3 April 2020, 92 patients were recruited, and a total of 42 patients in the IFN group and 39 patients in the control group completed the study.

Methods: We prospectively enrolled 30 treatment-naïve patients with confirmed COVID-19 after informed consent at Shanghai Public Health Clinical Center. The patients were randomized 1:1 to HCQ group and the control group. Patients in HCQ group were given HCQ 400 mg per day for 5 days plus conventional treatments, while those in the control group were given conventional treatment only. The primary endpoint was negative conversion rate of SARS-CoV-2 nucleic acid in respiratory pharyngeal swab on days 7 after randomization. This study has been approved by the Ethics Committee of Shanghai Public Health Clinical Center and registered online (NCT04261517). Results: One patient in HCQ group developed to severe during the treatment. On day 7, nucleic acid of throat swabs was negative in 13 (86.7%) cases in the HCQ group and 14 (93.3%) cases in the control group (P>0.05). The median duration from hospitalization to virus nucleic acid negative conservation was 4 (1, 9) days in HCQ group, which is comparable to that in the control group [2 (1, 4) days, Z=1.27, P>0.05]. The median time for body temperature normalization in HCQ group was 1 (0, 2) day after hospitalization, which was also comparable to that in the control group [1 (0, 3) day]. Radiological progression was shown on CT images in 5 cases (33.3%) of the HCQ group and 7 cases (46.7%) of the control group, and all patients showed improvement in follow-up examinations. Four cases (26.7%) of the HCQ group and 3 cases (20%) of the control group had transient diarrhea and abnormal liver function (P>0.05).

The primary end point was change in overall symptom severity over 14 days.\n\nStudy End Points\n\nThe initial primary outcome was an ordinal outcome by day 14 of not hospitalized, hospitalized, or intensive care unit stay or death. Secondary end points were symptom severity at day 5 and day 14 by 10-point visual analogue scale, nominal incidence of all hospitalizations and deaths, and incidence of study medicine withdrawal.\n\nChanges in End Point and Sample Sizes\n\nBefore the first interim analysis on 24 April 2020, it became apparent that the pooled event rate of hospitalization or death was substantially lower than our initial 10% expectation (original sample size calculations as described in Statistical Analysis section). Without unblinding of treatment allocation or analysis of the data, the principal investigator proposed to the data and safety monitoring board (DSMB) that we modify the primary end point to the change in overall symptom severity over 14 days as longitudinally measured on a 10-point visual analogue scale. The DSMB approved the change on 24 April 2020. The change was necessary because the low event rate of hospitalizations or deaths in the trial would have required increasing the sample size to 6000 participants, which was not attainable. With enrollment of at least 200 participants per group, we determined that the revised trial would have 90% power (with a 2-sided α level of 0.05) to detect a statistically significant difference between the groups for a change in symptom severity score as small as 0.25 point on the 10-point visual analogue scale.

Interventions mitigating progression to mechanical ventilation in COVID 19 would markedly improve outcome and reduce healthcare utilization. We hypothesized that immunomodulation with IVIG would improve oxygenation and reduce length of hospital stay and progression to mechanical ventilation in COVID 19 pneumonia.\nMethods. Patients with COVID 19 were randomized 1:1 to prospectively receive standard of care (SOC) plus IVIG 0.5 g/kg/day x 3 days with methylprednisolone 40 mg 30 minutes before infusion versus SOC alone.\n\nClinical data extraction and analysis. Relevant clinical and laboratory information was captured to allow for group comparisons, including the calculation of Charlson comorbidity index (https://www.mdcalc.com/charlson comorbidity index cci) and APACHE II acute illness severity score (https://www.mdcalc.com/apache ii score#next steps). The alveolar arterial (A a) gradient was calculated (https://www.mdcalc.com/a a o2 gradient) for each subject at the time of enrollment based on arterial blood gases when available or based on PaO2 extrapolated SpO2 and fraction of inspired oxygen (FiO2). Interleukin 6 was measured from blood 24 48 hours after enrollment (https://ltd.aruplab.com/Tests/Pub/0051537).\n\nClinical outcomes. The two patient groups were well matched with respect to their\nCharlson comorbidity index and severity of illness APACHE 2 scores (Figure 2). Median\nCharlson index was 2 for both groups. Median APACHE 2 score was 7 for SOC and 7.5 the IVIG study group. Figure 2 demonstrates the subjects in the control SOC and treatment IVIG group that developed a need for mechanical ventilation after study enrollment, denoted as the red data points. An overall trend is for receipt of mechanical ventilation in the IVIG group in the 2 patients with highest comorbidity and illness severity scores, whereas in the SOC group mechanical ventilation requirement developed across the entire spectrum of scores.\nAmong the entire enrolled and evaluated subjects in each arm, 2 patients in the IVIG arm and 7 patients in the control SOC arm developed a need for mechanical ventilation.\nAmong these 7 SOC patients, 6 received ventilation and 1 was made a ‘do not intubate’ and the patient expired within 24 hours. The difference in receipt of mechanical ventilation was not statistically significant between the two groups (p=0.12, Fisher exact test). Among subjects whose respiratory failure progressed to the need for mechanical ventilation, 1 of 2 IVIG subjects and 2 of 3 control subjects also received concomitant convalescent plasma. Concomitant glucocorticoid therapy was given to 5 of the 7 control subjects who progressed to mechanical ventilation.

This resulted in 1 of 2 IVIG patients and 3 of 7 SOC subjects that required ventilation receiving remdesivir.\nAlveolar arterial (A a) gradients were calculated directly from arterial blood gas or estimated based on PaO2 and FiO2 measurement. Based on an increase in APACHE II severity of illness scoring associated with achieving and A a gradient of > 200 mm Hg (+2 points), subjects were stratified into those with A a gradient < 200 mm Hg or >200 mm Hg, corresponding to a PaO2/FiO2 of <140, or the approximate requirement of 6 liters O2 by nasal cannula for a PaO2 of <92%. As shown in Figure 3A, none of the 7 subjects (5 SOC, 2 IVIG) with A a gradient < 200 mm Hg progressed to mechanical ventilation, but for subjects with A a gradient of > 200 mm Hg at enrollment, the progression to mechanical ventilation was 7/12 (58%) in the SOC control arm vs 2/14 (14%) in the IVIG, a difference that was statistically significant (p=0.038, Fisher Exact test).\nEvaluation of overall hospital course, including length of hospital stay and length of ICU stay also was highly dependent on A a gradient stratification. Among the 7 patients with A a gradient < 200 mm Hg, no patient required ICU stay during their illness and length of hospital stay were 3 8 days. However, for the subjects with A a gradient > 200 at enrollment, median length of hospital stay was 19 (range 4 30) and 11 (range 5 22) days for SOC and IVIG groups, respectively (p=0.013, Mann Whitney U test, Figure 3B).\nMedian ICU stay were 12.5 days (range 1 29) and 2.5 days (range 0 16) for SOC and IVIG, respectively (p=0.006, Mann Whitney U test, Figure 3C).

The supplementary Figure shows schematically the hospital stays from the time of admission of the 33 enrolled patients with respect to medical floor and ICU stays with and without mechanical ventilation.\nImprovement in oxygenation was evaluated by examining the PaO2/FiO2 ratio at the day of enrollment and 7 days after enrollment in individual subjects for SOC (Figure 4A) and IVIG (Figure 4B). Differences in day 7 PaO2/FiO2 minus enrollment PaO2/FiO2 are shown in Figure 4C for both groups, with negative numbers representing worsening in oxygenation. Among the entire subject population, median improvement PaO2/FiO2 for IVIG was +153 (range +35 to + 330) and was better than SOC +90 (range 115 to\n+280), but did not reach statistical significance (p=0·057, Mann Whitney U test).\nHowever, when refocusing on the higher risk patients with A a gradient >200 at enrollment, median improvement of PaO2/FiO2 for IVIG was significantly greater than SOC, with median (range) of +131 (+35 to +330) versus +44·5 ( 115 to +157) (p=0·01,\nMann Whitney U test).\nFigure 4C denotes subjects in the SOC group who did not receive any glucocorticoid therapy as red data points. Seven subjects in SOC did not receive glucocorticoids, 4 of whom were in the low risk group with A a gradient < 200. Of the remaining 3 patients, 2 progressed to requiring mechanical ventilation, one of which was made do not intubate and died. PaO2/FiO2 changes between enrollment and day 7 of the 10 SOC patients who received glucocorticoid therapy (median 11 days) was median +53 (range 115 to\n+216), a difference that remained significantly lower than the IVIG group (p=0.0057,\nMann Whiney U test). .CC-BY-NC-ND 4.0 International licenseIt is made available under a is the author/funder, who has granted medRxiv a license to display the preprint in perpetuity.(which was not certified by peer review)\nThe copyright holder for this preprintthis version posted July 25, 2020.;https://doi.org/10.1101/2020.07.20.20157891doi:medRxiv preprint\n\n", "entities": [{"id": "T1", "type": "OtherOutcome", "offsets": [[1628, 1650]], "text": "mechanical ventilation"}, {"id": "T2", "type": "OtherOutcome", "offsets": [[3369, 3402]], "text": "Alveolar arterial (A a) gradients"}, {"id": "T4", "type": "OtherOutcome", "offsets": [[4737, 4752]], "text": "Median ICU stay"}, {"id": "T5", "type": "OtherOutcome", "offsets": [[4580, 4610]], "text": "median length of hospital stay"}, {"id": "T3", "type": "OtherOutcome", "offsets": [[5566, 5592]], "text": "Improvement in oxygenation"}, {"id": "T6", "type": "OtherOutcome", "offsets": [[6471, 6505]], "text": "receive any glucocorticoid therapy"}], "relations": []} {"id": "53", "type": "silver", "text": " Outcomes assessment: The primary outcomes included virological and clinical evaluations.\nTime to SARS-CoV-2 RNA negativization (absence of the virus according to the RT-PCR) in positive patients after starting antiviral therapy was the virological endpoint.

The first was the number of patients with disease progression, defined as hospitalization or death. The second primary end point was the Patient Acceptable Symptom State (PASS), defined as the value of symptoms the patient considered to be well-being thresholds of pain and function. Our study incorporated the most widely used anchoring question to identify PASS cut-off points, which was: “Taking into account all your daily activities, do you consider your current state satisfactory in relation to pain level and functional impairment?” The response options were “Yes” or “No” [35][36](34)[37]. Treatment success was defined as no disease progression, or a PASS answered in the affirmative on days 3, 5, or 7 of follow-up. The third endpoint was the change from the baseline in the patient overall self-assessment, which was determined by the response to the question: Considering all the ways in which illness and health conditions may affect you at this time, please indicate below how you are doing? The response options were measured on the 0–10 VAS, from ‘very well’ (score of 0) to ‘very poorly’ (score of 10). That question is validated in the Routine Assessment of Patient Index Data 3 (RAPID3), which is a pooled index of the three patient-reported Core Data Set measures of the American College of Rheumatology, and it has previously been used to determine the activity of autoimmune diseases, degenerative diseases, such as osteoarthritis (18), and infectious diseases with a strong component of general malaise, such as chikungunya fever (37). That end point is similar to the symptom severity score (self-assessed using a 10-point VAS) recently used in a clinical trial that evaluated the efficacy of hydroxychloroquine in non-hospitalized patients with COVID-19 [38]. The secondary endpoints were changes from the baseline in different types of body pain (arthralgia, myalgia, headache, and sore throat), or more exactly, the difference between the values at enrollment and on days 3, 5, and 7 of follow-up. Pain was measured on the 0–10 VAS (27). Intensity of pain was recorded, from ‘no pain’ (score of 0) to ‘worst imaginable pain’ (score of 10). The VAS was selected because it is the validated scale that best evaluates pain in diseases (28,29), at present, and because it has also been used as a primary endpoint in other clinical trials (30). Patients completed the previously validated fatigue VAS (0–10 scale) [37], which states: “How much of a problem has unusual fatigue or tiredness been for you today” and was anchored from 0 (fatigue is not a problem) to 10 (fatigue is a major problem). Daily coughing episodes were reported by the patient on a numerical scale from 0 to 20. If there were more than 20 episodes, they were registered as 20. Dyspnea was determined once a day through the Borg scale, from 0 to 10, in which 0 is no dyspnea and 10 is extremely severe dyspnea [37]. Nausea, vomiting, diarrhea, dizziness, conjunctivitis, rhinorrhea, exanthema, skin rash, and loss of sense of smell or taste were catalogued as present or absent for each day of follow-up. Adverse events were monitored by the researchers through anamnesis and abnormal routine laboratory test results. Follow-up was carried out for at least 20 days or until patient outcome (cure or death). Daily follow-up was suspended in the hospitalized patients, and from the day of hospital admission, their registers were considered lost data and were not considered in the analysis from that day forward, with the exception of the PASS, in which its subsequent registers were reported as a negative acceptable symptom state.

We conducted a prospective, randomized, open-label, multicenter trial of favipiravir for the treatment of COVID-19 at 25 hospitals across Japan. Eligible patients were adolescents and adults admitted with COVID-19 who were asymptomatic or mildly ill and had an Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1. Patients were randomly assigned at a 1:1 ratio to early or late favipiravir therapy (in the latter case, the same regimen starting on day 6 instead of day 1).\nThe primary endpoint was viral clearance by day 6. The secondary endpoint was change in viral load by day 6. Exploratory endpoints included time to defervescence and resolution of symptoms. Eighty-nine patients were enrolled, of whom 69 were virologically evaluable. Viral clearance occurred within 6 days in 66.7% and 56.1% of the early and late treatment groups (adjusted hazard ratio [aHR], 1.42; 95% confidence interval [95% CI], 0.76 to 2.62). Of 30 patients who had a fever (\u000237.5°C) on day 1, times to defervescence were 2.1 days and 3.2 days in the early and late treatment groups (aHR, 1.88; 95% CI, 0.81 to 4.35). During therapy, 84.1% developed transient hyperuricemia. Favipiravir did not significantly improve viral clearance as measured by reverse transcription-PCR (RT-PCR) by day 6 but was associated with numerical reduction in time to defervescence.\nNeither disease progression nor death occurred in any of the patients in either treatment group during the 28-day participation.

No significant differences were observed in the median time, 11 days ± 8.0 for CIGB-325 plus standard care and 12 days ± 6 for standard care alone (p = 0.614). Thus, time to SARS-Cov2 viral clearance in the nasopharynx swabs behaved similarly for both treatments over the time.\nThe clinical status was classified in categories of asymptomatic, mild, moderate or severe disease and it was followed up until ending treatment and thereafter for both groups. In the intent-to-treat population of CIGB-325 group at day 6 there were 2/10 patients that remained asymptomatic since initiation of treatment, 2/10 changed from severe to moderate, 1/10 from moderate to asymptomatic, 1/10 from mild to asymptomatic and 4/10 did not change their clinical status during the treatment. Otherwise, in the control 6/10 patients remained asymptomatic since initiation of treatment, 1/10 changed from mild to asymptomatic and 3/10 did not change their clinical status during the treatment. Additionally, chest-CT analysis was performed to investigate the effect of CIGB-325 over the Covid-19 pulmonary lesions. For that purpose, both number and lesion’s extent at day 0 and after treatment (day 7) were compared just in those patients analyzed per protocol (Table 1). Importantly, CIGB-325 treatment significantly reduced the median number of pulmonary lesions from 9.5 ± 10 (day 0) to 5.5 ± 10 (day 7) (p = 0.042). Conversely, no substantial change was observed in the control group. Proportion of patients with reduction of pulmonary lesions was higher in the CIGB-325 group compared with control according to the Bayesian analysis (pDif > 0; 0.951) (Table 1).\nThe effect over lesion’s extent showed in Supp. 2 including those patients analyzed per protocol indicates that CIGB-325 treatment also reduced the median of lesion’s extent after consecutive-5 day regimen although not significantly. Otherwise, any kind of reduction was observed in the control group. Importantly, proportion of patients with reduction of lesion’s extent was higher in the CIGB-325 group (4/7) compared with control (1/9) (pDif > 0; 0.982) (Bayesian analysis).\nThe overall chest-CT response was also analyzed considering the lesion’s extent and the pattern of Covid-19 typical chest-CT abnormalities (Supp. 3). The analysis per protocol showed that 50% (3/6) of patients in the CIGB-325 group had a favorable overall chest-CT response compared with 28.6% (2/7) in the control (pDif > 0; 0.796) (Bayesian analysis). Importantly, any patient had progression in the CIGB-325 group and 28.6% (2/7) in the control group did it. Representative images of chest-CT evolution from one CIGB-325 treated patient are shown in Fig. 2.\nRepresentative chest-CT images from one patient in the CIGB-325 group at day 0 and 7.\nWe also investigated the levels of Creatinine Phospho Kinase (CPK), Reactive C-Protein (RCP), and Lactate dehydrogenase (LDH) in plasma.
