Brivanib Alaninate

	Brivanib Alaninate Brivanib alaninate (INN/USAN) also known as BMS-582664 is an investigational, anti-tumorigenic drug for oral administration. The drug is being developed by Bristol-Myers Squibb for the treatment of hepatocellular carcinoma or HCC (also called ''malignant hepatoma''), the most common type of liver cancer. Brivanib is no longer in active development. Brivanib alaninate is a multitargeted tyrosine kinase inhibitor (as is sorafenib). Brivanib alaninate also inhibits VEGFR and fibroblast growth factor receptors (FGFR), which is known to play a major role in the etiopathogenesis of HCC. To date, brivanib alaninate has been investigated in 29 studies, including more than 4,000 patients around the world. Hepatocellular carcinoma (summary) Hepatocellular carcinoma is a primary cancer of the liver and is more common in men than in women. The disease occurs mostly in people who have scarring of the liver (cirrhosis) or after infection with hepatitis B or hepatitis C. Symptoms include ...

	Overall Survival Survival rate is a part of survival analysis. It is the proportion of people in a study or treatment group still alive at a given period of time after diagnosis. It is a method of describing prognosis in certain disease conditions, and can be used for the assessment of standards of therapy. The survival period is usually reckoned from date of diagnosis or start of treatment. Survival rates are based on the population as a whole and cannot be applied directly to an individual. There are various types of survival rates (discussed below). They often serve as endpoints of clinical trials and should not be confused with mortality rates, a population metric. Overall survival Patients with a certain disease (for example, colorectal cancer) can die directly from that disease or from an unrelated cause (for example, a car accident). When the precise cause of death is not specified, this is called the overall survival rate or observed survival rate. Doctors often use mean overall survival ...

picture info	Fibroblast Growth Factor Receptor A fibroblast is a type of biological cell that synthesizes the extracellular matrix and collagen, produces the structural framework ( stroma) for animal tissues, and plays a critical role in wound healing. Fibroblasts are the most common cells of connective tissue in animals. Structure Fibroblasts have a branched cytoplasm surrounding an elliptical, speckled nucleus having two or more nucleoli. Active fibroblasts can be recognized by their abundant rough endoplasmic reticulum. Inactive fibroblasts (called fibrocytes) are smaller, spindle-shaped, and have a reduced amount of rough endoplasmic reticulum. Although disjointed and scattered when they have to cover a large space, fibroblasts, when crowded, often locally align in parallel clusters. Unlike the epithelial cells lining the body structures, fibroblasts do not form flat monolayers and are not restricted by a polarizing attachment to a basal lamina on one side, although they may contribute to basal lamina components in so ...

	VEGFR VEGF receptors are receptors for vascular endothelial growth factor (VEGF). There are three main subtypes of VEGFR, numbered 1, 2 and 3. Also, they may be membrane-bound (mbVEGFR) or soluble (sVEGFR), depending on alternative splicing. Inhibitors of VEGFR are used in the treatment of cancer. VEGF Vascular endothelial growth factor (VEGF) is an important signaling protein involved in both vasculogenesis (the formation of the circulatory system) and angiogenesis (the growth of blood vessels from pre-existing vasculature). As its name implies, VEGF activity is restricted mainly to cells of the vascular endothelium, although it does have effects on a limited number of other cell types (e.g. stimulation monocyte/ macrophage migration). ''In vitro'', VEGF has been shown to stimulate endothelial cell mitogenesis and cell migration. VEGF also enhances microvascular permeability and is sometimes referred to as vascular permeability factor. Receptor biology All members of the VEG ...

	In Vivo Studies that are ''in vivo'' (Latin for "within the living"; often not italicized in English) are those in which the effects of various biological entities are tested on whole, living organisms or cells, usually animals, including humans, and plants, as opposed to a tissue extract or dead organism. This is not to be confused with experiments done ''in vitro'' ("within the glass"), i.e., in a laboratory environment using test tubes, Petri dishes, etc. Examples of investigations ''in vivo'' include: the pathogenesis of disease by comparing the effects of bacterial infection with the effects of purified bacterial toxins; the development of non-antibiotics, antiviral drugs, and new drugs generally; and new surgical procedures. Consequently, animal testing and clinical trials are major elements of ''in vivo'' research. ''In vivo'' testing is often employed over ''in vitro'' because it is better suited for observing the overall effects of an experiment on a living subject. In dr ...

picture info	VEGFR-2 Inhibitor VEGFR-2 inhibitor, also known as kinase insert domain receptor(KDR) inhibitor, are Tyrosine-kinase inhibitor, tyrosine kinase receptor inhibitors that reduce angiogenesis or lymphangiogenesis, leading to anticancer activity. Generally they are small, synthesised molecules that bind competitively to the ATP-site of the tyrosine kinase domain. VEGFR-2 selective inhibitor can interrupt multiple signaling pathways involved in tumor, including Cell proliferation, proliferation, metastasis and angiogenesis. __TOC__ VEGFR The VEGF receptor family contains three members, which are all receptor tyrosine kinases (VEGFR-1, VEGFR-2 and VEGFR-3). VEGFR-1, or FLT-1 (fms-like tyrosine kinase), are important for hematopoietic stem cell development, VEGFR-2 (KDRor FLK-1 (fetal liver kinase)) are vital to Endothelium, vascular endothelial cell development and VEGFR-3 (FLT-4) for lymphatic endothelial cell development. Binding of VEGF to the VEGFR induces a conformational change in the receptor produ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
