Sibrotuzumab is a humanized monoclonal antibody intended for the treatment of cancer. It binds to FAP In 2003 it failed a phase II clinical trial for metastatic colorectal cancer Colorectal cancer (CRC), also known as bowel cancer, colon cancer, or rectal cancer, is the development of cancer from the colon or rectum (parts of the large intestine).

Fibroblast Activation Protein
Fibroblast activation protein alpha (FAP-alpha) also known as prolyl endopeptidase FAP is an enzyme that in humans is encoded by the FAP gene. Prolyl endopeptidase FAP is a 170 kDa membrane-bound gelatinase. It was independently identified as a surface glycoprotein recognized by the F19 monoclonal antibody in activated fibroblasts and a Surface Expressed Protease (seprase) in invasive melanoma cells. Structure and enzymatic activity FAP is a 760 amino acid long type II transmembrane glycoprotein. It contains a very short cytoplasmic N terminal part (6 amino acids), a transmembrane region (amino acids 7–26), and a large extracellular part with an alpha/beta-hydrolase domain and an eight-bladed beta-propeller domain.; A soluble form of FAP, which lacks the intracellular and transmembrane part, is present in blood plasma. FAP is a non-classical serine protease, which belongs to the S9B prolyl oligopeptidase subfamily. Other members of the S9B subfamily are DPPIV, DPP8 and D ...

Humanized Monoclonal Antibody
Humanized antibodies are antibodies from non-human species whose protein sequences have been modified to increase their similarity to antibody variants produced naturally in humans. The process of "humanization" is usually applied to monoclonal antibodies developed for administration to humans (for example, antibodies developed as anti-cancer drugs). Humanization can be necessary when the process of developing a specific antibody involves generation in a non-human immune system (such as that in mice). The protein sequences of antibodies produced in this way are partially distinct from homologous antibodies occurring naturally in humans, and are therefore potentially immunogenic when administered to human patients (see also Human anti-mouse antibody). The International Nonproprietary Names of humanized antibodies end in ''-zumab'', as in ''omalizumab'' (see Nomenclature of monoclonal antibodies). Humanized antibodies are distinct from chimeric antibodies. The latter also have thei ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Colorectal Cancer
Colorectal cancer (CRC), also known as bowel cancer, colon cancer, or rectal cancer, is the development of cancer from the colon or rectum (parts of the large intestine). Signs and symptoms may include blood in the stool, a change in bowel movements, weight loss, and fatigue. Most colorectal cancers are due to old age and lifestyle factors, with only a small number of cases due to underlying genetic disorders. Risk factors include diet, obesity, smoking, and lack of physical activity. Dietary factors that increase the risk include red meat, processed meat, and alcohol. Another risk factor is inflammatory bowel disease, which includes Crohn's disease and ulcerative colitis. Some of the inherited genetic disorders that can cause colorectal cancer include familial adenomatous polyposis and hereditary non-polyposis colon cancer; however, these represent less than 5% of cases. It typically starts as a benign tumor, often in the form of a polyp, which over time becomes cancerous. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
