Actoxumab
Actoxumab is a human monoclonal antibody designed for the prevention of recurrence of '' Clostridium difficile'' infection. This drug, along with bezlotoxumab, was developed through Phase II efficacy trials by a partnership between Medarex Inc and MassBiologics of the University of Massachusetts Medical School The University of Massachusetts Chan Medical School is a public medical school in Worcester, Massachusetts. It is part of the University of Massachusetts system. It is home to three schools: the T.H. Chan School of Medicine, the Morningside Grad .... The project was then licensed to Merck & Co., Inc. for further development and commercialization. A study compared it with bezlotoxumab (that targets CD toxin-B) and found Actoxumab less effective.

Bezlotoxumab
Bezlotoxumab, sold under the brand name Zinplava, is a human monoclonal antibody designed for the prevention of recurrence of ''Clostridioides difficile'' infections. This drug, along with actoxumab, was developed through Phase II efficacy trials by a partnership between Medarex Inc and MassBiologics of the University of Massachusetts Medical School. The project was then licensed to Merck Sharp & Dohme Corp for further development and commercialization. Actoxumab and bezlotoxumab are fully human monoclonal antibodies which bind ''C. difficile'' toxins A and B, respectively. A Phase III trial only showed a benefit from bezlotoxumab; the combination of actoxumab and bezlotoxumab worked no better to prevent recurrence of ''C. difficile'' associated diarrhea than bezlotoxumab alone. Progress towards FDA approval On June 9, 2016, the U.S. FDA's Antimicrobial Drugs Advisory Committee (formerly known as the Anti-Infective Drugs Advisory Committee) met to discuss bezlotoxumab.

University Of Massachusetts Medical School
The University of Massachusetts Chan Medical School is a public medical school in Worcester, Massachusetts. It is part of the University of Massachusetts system. It is home to three schools: the T.H. Chan School of Medicine, the Morningside Graduate School of Biomedical Sciences, and the Tan Chingfen Graduate School of Nursing, as well as a biomedical research enterprise and a range of public-service initiatives throughout the state. History UMMS was established by the 162nd Massachusetts General Court in 1962 to provide residents of the commonwealth an opportunity to study medicine at an affordable cost and to increase the number of primary-care physicians practicing in the commonwealth's under-served areas. The School of Medicine accepted its first class of 16 students in 1970. Six years later a 371-bed hospital opened on campus; the Graduate School of Biomedical Sciences opened in 1979, and the Graduate School of Nursing opened in 1986. In 1998 the UMMS system of hospitals a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Clostridium Difficile (bacteria)
''Clostridioides difficile'' ( syn. ''Clostridium difficile'') is a bacterium that is well known for causing serious diarrheal infections, and may also cause colon cancer. Also known as ''C. difficile'', or ''C. diff'' (), is Gram-positive species of spore-forming bacteria. ''Clostridioides'' spp. are anaerobic, motile bacteria, ubiquitous in nature and especially prevalent in soil. Its vegetative cells are rod-shaped, pleomorphic, and occur in pairs or short chains. Under the microscope, they appear as long, irregular (often drumstick- or spindle-shaped) cells with a bulge at their terminal ends (forms subterminal spores). Under Gram staining, ''C. difficile'' cells are Gram-positive and show optimum growth on blood agar at human body temperatures in the absence of oxygen. ''C. difficile'' is catalase- and superoxide dismutase-negative, and produces up to three types of toxins: enterotoxin A, cytotoxin B and Clostridioides difficile transferase (CDT). Under stress condition ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Monoclonality
Monoclonality refers to the state of a line of cells that have been derived from a single clonal origin. Thus "monoclonal cells" can be said to form a single cloning#Cellular cloning, clone. The term ''monoclonal'' comes from the Ancient Greek ''monos'', meaning "alone" or "single", and ''klon'', meaning "twig". The process of replication can occur ''in vivo'', or may be stimulated ''in vitro'' for laboratory manipulations. The use of the term typically implies that there is some method to distinguish between the cells of the original population from which the single ancestral cell is derived, such as a random genetic alteration, which is inherited by the progeny. Common usages of this term include: * Monoclonal antibody: A single Hybridoma technology, hybridoma cell, which by chance includes the appropriate V(D)J recombination to produce the desired antibody, is cloned to produce a large population of identical cells. In informal laboratory jargon, the monoclonal antibodies is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
American Medical Association
The American Medical Association (AMA) is a professional association and lobbying group of physicians and medical students. Founded in 1847, it is headquartered in Chicago, Illinois. Membership was approximately 240,000 in 2016. The AMA's stated mission is "to promote the art and science of medicine and the betterment of public health." The Association also publishes the ''Journal of the American Medical Association'' (JAMA). The AMA also publishes a list of Physician Specialty Codes which are the standard method in the U.S. for identifying physician and practice specialties. The American Medical Association is governed by a House of Delegates as well as a board of trustees in addition to executive management. The organization maintains the AMA Code of Medical Ethics, and the AMA Physician Masterfile containing data on United States Physicians. The ''Current Procedural Terminology'' coding system was first published in 1966 and is maintained by the Association. It has also publi ...

Phases Of Clinical Research
The phases of clinical research are the stages in which scientists conduct experiments with a health intervention to obtain sufficient evidence for a process considered effective as a medical treatment. For drug development, the clinical phases start with testing for safety in a few human subjects, then expand to many study participants (potentially tens of thousands) to determine if the treatment is effective. Clinical research is conducted on drug candidates, vaccine candidates, new medical devices, and new diagnostic assays. Summary Clinical trials testing potential medical products are commonly classified into four phases. The drug development process will normally proceed through all four phases over many years. If the drug successfully passes through Phases I, II, and III, it will usually be approved by the national regulatory authority for use in the general population. Phase IV trials are 'post-marketing' or 'surveillance' studies conducted to monitor safety over sever ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Medarex
Medarex (former NASDAQ symbol: MEDX ) was an American biopharmaceutical company based in Princeton, New Jersey, with manufacturing facilities in Bloomsbury and Annandale, New Jersey, and research facilities in Milpitas and Sunnyvale, California. In 2009, Medarex was purchased by Bristol Myers Squibb. Medarex developed monoclonal antibodies to CTLA-4 and PD-1, which are proteins on the surface of T cells. T cells attack cancer cells, but CTLA-4 and PD-1 act as "brakes" on the T cell's anti-cancer activities. The monoclonal antibodies bind to these proteins and block them, releasing the T cell to attack cancer cells.

Monoclonal Antibodies
A monoclonal antibody (mAb, more rarely called moAb) is an antibody produced from a cell Lineage made by cloning a unique white blood cell. All subsequent antibodies derived this way trace back to a unique parent cell. Monoclonal antibodies can have monovalent affinity, binding only to the same epitope (the part of an antigen that is recognized by the antibody). In contrast, polyclonal antibodies bind to multiple epitopes and are usually made by several different antibody-secreting plasma cell lineages. Bispecific monoclonal antibodies can also be engineered, by increasing the therapeutic targets of one monoclonal antibody to two epitopes. It is possible to produce monoclonal antibodies that specifically bind to virtually any suitable substance; they can then serve to detect or purify it. This capability has become an investigative tool in biochemistry, molecular biology, and medicine. Monoclonal antibodies are being used on a clinical level for both the diagnosis and therapy ...
