Biologics provide immunotherapy [4] and can function as disease-modifying antirheumatic drugs. [3] Biologics can generally be grouped by their "class", that is, their specific mechanism of action and affected targets. Some classes are TNF inhibitors, anti-IL-17A antibodies, and IL-23 antibodies. [7]
This list of over 500 monoclonal antibodies includes approved and investigational drugs as well as drugs that have been withdrawn from market; consequently, the column Use does not necessarily indicate clinical usage. See the list of FDA-approved therapeutic monoclonal antibodies in the monoclonal antibody therapy page.
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 .
Anti-cancer monoclonal antibodies can be targeted against malignant cells by several mechanisms. Ramucirumab is a recombinant human monoclonal antibody and is used in the treatment of advanced malignancies. [18] In childhood lymphoma, phase I and II studies have found a positive effect of using antibody therapy. [19]
These types of antibodies are typically called monoclonal antibodies because they are created to target one specific antigen. [2] Herceptin and Avastin, two widely used cancer fighting drugs, are examples of monoclonal antibodies. For several decades, and until recently, mice were used extensively in the production of monoclonal antibodies (MAbs).
One study has reported the isolation of a hybridoma cell line (clone 1E10), which produces a monoclonal antibody (IgM, k isotype). This monoclonal antibody shows specific immuno-cytochemical staining of nucleoli. [12] Tissues and tumours can be classified based on their expression of certain markers, with the help of monoclonal antibodies.
However, monoclonal antibodies also mean that overall affinity is lower owing to the limited ability to recognize different epitopes on the antigens, which may lead to incomplete elimination of pathogens and tumor cells. The production time and cost is high as well, limiting its generalizability and prevalence of usage. [5]
Ipilimumab, sold under the brand name Yervoy, is a monoclonal antibody medication that works to activate the immune system by targeting CTLA-4, a protein receptor that downregulates the immune system.
