Vanucizumab (INN; development code RG7221) is an experimental humanized monoclonal antibody designed for the treatment of cancer. [1] [2]
Vanucizumab is a bi-specific monoclonal antibody composed of two different heavy chains and two different light chains. One arm of the antibody binds Angiopoietin-2 (Ang2) and the other is based on bevacizumab (Avastin), binding Vascular Endothelial Growth Factor A (VEGF-A). The antibody is designed to inhibit both VEGF-A and Ang2 simultaneously to offer superior clinical benefit compared to VEGF-A inhibition alone.[ citation needed ]
This drug was developed by Genentech/Roche.[ citation needed ]
An international nonproprietary name (INN) is an official generic and nonproprietary name given to a pharmaceutical drug or an active ingredient. INNs are intended to make communication more precise by providing a unique standard name for each active ingredient, to avoid prescribing errors. The INN system has been coordinated by the World Health Organization (WHO) since 1953.
The nomenclature of monoclonal antibodies is a naming scheme for assigning generic, or nonproprietary, names to monoclonal antibodies. An antibody is a protein that is produced in B cells and used by the immune system of humans and other vertebrate animals to identify a specific foreign object like a bacterium or a virus. Monoclonal antibodies are those that were produced in identical cells, often artificially, and so share the same target object. They have a wide range of applications including medical uses.
Mertansine, also called DM1, is a thiol-containing maytansinoid that for therapeutic purposes is attached to a monoclonal antibody through reaction of the thiol group with a linker structure to create an antibody-drug conjugate (ADC).
Drug nomenclature is the systematic naming of drugs, especially pharmaceutical drugs. In the majority of circumstances, drugs have 3 types of names: chemical names, the most important of which is the IUPAC name; generic or nonproprietary names, the most important of which are international nonproprietary names (INNs); and trade names, which are brand names. Under the INN system, generic names for drugs are constructed out of affixes and stems that classify the drugs into useful categories while keeping related names distinguishable. A marketed drug might also have a company code or compound code.
