The magic bullet is a scientific concept developed by a German Nobel laureate Paul Ehrlich in 1907. While working at the Institute of Experimental Therapy (Institut für experimentelle Therapie), Ehrlich formed an idea that it could be possible to kill specific microbes (such as bacteria), which cause diseases in the body, without harming the body itself. He named the hypothetical agent as Zauberkugel, and used the English translation "magic bullet" in The Harben Lectures at London

The FDA animal efficacy rule (also known as animal rule) applies to development and testing of drugs and biologicals to reduce or prevent serious or life-threatening conditions caused by exposure to lethal or permanently disabling toxic agents (chemical, biological, radiological, or nuclear substances), where human efficacy trials are not feasible or ethical. The animal efficacy rule was finalized by the FDA and authorized by the United States Congress in 2002, following the September 11 attacks and concerns regarding bioterrorism. Summary The FDA can rely on evidence from animal studies to provide substantial evidence of product effectiveness if: There is a reasonably well-understood mechanism for the toxicity of the agent and its amelioration or prevention by the product; The effect is demonstrated in either: More than one animal species expected to react with a response predictive for humans; or One well-characterized animal species model (adequately evaluated for its responsiveness in humans) for predicting the response in humans

A biopharmaceutical, also known as a biological medical product, or biologic, is any pharmaceutical drug product manufactured in, extracted from, or semisynthesized from biological sources. Different from totally synthesized pharmaceuticals, they include vaccines, whole blood, blood components, allergenics, somatic cells, gene therapies, tissues, recombinant therapeutic protein, and living medicines used in cell therapy. Biologics can be composed of sugars, proteins, nucleic acids, or complex combinations of these substances, or may be living cells or tissues

Stromagen is a product that is made of stem cells taken from a patient's bone marrow and grown in the laboratory. After a patient's bone marrow is destroyed by treatment with whole body irradiation or chemotherapy, these cells are injected back into the patient to help rebuild bone marrow. Stromagen has been studied in the prevention of graft-versus-host disease during stem cell transplant in patients receiving treatment for cancer

Bacterial therapy is the therapeutic use of bacteria to treat diseases. Bacterial therapeutics are living medicines, and may be wild type bacteria (often in the form of probiotics) or bacteria that have been genetically engineered to possess therapeutic properties that is injected into a patient. Other examples of living medicines include cellular therapeutics (including immunotherapeutics), activators of anti-tumor immunity, or synergizing with existing tools and approaches

Biomanufacturing is a type of manufacturing or biotechnology that utilizes biological systems to produce commercially important biomaterials and biomolecules for use in medicines, food and beverage processing, and industrial applications. Biomanufacturing products are recovered from natural sources, such as blood, or from cultures of microbes, animal cells, or plant cells grown in specialized equipment. The cells used during the production may have been naturally occurring or derived using genetic engineering techniques

Bioproduction is the production of biologics-based therapeutic drugs including protein-based therapeutics, vaccines, gene therapies as well as cell therapies; drugs so complex they can only be made in living systems or indeed are a living system (cell therapies). In practice, ‘bioproduction’ has become loosely synonymous with ‘bioprocessing’ as a way to describe the manufacturing process using, cell culture, chromatography, formulation and related analytical testing for large molecule drugs, vaccines and cellular therapies. Many combinations of reactor types and culture modes are now available for use in bioproduction: e

Bovhyaluronidase azoximer, sold under the brand name Longidaze, is a conjugate of proteolytic enzyme hyaluronidase with high- molecular weight copolymer that forms a component of combination therapy regimens for treatment and prevention of diseases associated with connective tissue hyperplasia. The most frequently observed adverse reactions seen with bovhyaluronidase azoximer include pain at site of injection and injection site reaction n such as skin redness, itching and oedema. All local reactions resolve themselves in 48 – 72 hours

Catridecacog, sold under the brand name Tretten in the US and NovoThirteen in the EU) is a class of recombinant factor XIII A-subunit based biopharmaceutical medicine, indicated in patients with a rare clotting disorder, congenital factor XIII A-subunit deficiency, which is a kind of Factor XIII deficiency. The medication prevents bleeding in patients with this condition, and has been approved by the U. S

Condoliase (Hernicore) is a biopharmaceutical for the treatment of lumbar disc herniation. Clinical trials have shown its benefit in alleviation lumbar disc herniation associated low back pain and disability, although some concerns have been suggested with regard to promotion of disc degeneration. Condoliase is derived from the enzyme mucopolysaccharidase from the Gram-negative bacteria Proteus vulgaris

The Golden LEAF Biomanufacturing Training and Education Center (BTEC) is a multidisciplinary instructional center at North Carolina State University that provides education and training to develop skilled professionals for the biomanufacturing industry. Biomanufacturing refers to the use of living organisms or other biological material to produce commercially viable products. Examples include therapeutic proteins, monoclonal antibodies, and vaccines for medical use; amino acids and enzymes for food manufacturing; and biofuels and biochemicals for industrial applications
