BISPECIFIC ANTIBODIES MARKET ANALYSIS

Market Challenges And Opportunities

Due to its dual specificity, bispecific antibody can aid in redirecting T cells to tumor cells, blocking two different signaling pathways simultaneously, dual targeting of different disease mediators, and delivering payloads to targeted sites.  Catumaxomab and blinatumomab are the two U.S. FDA approved bispecific antibody products, which would fuel growth of the bispecific antibodies market. Bispecific antibodies can be divided into three main classes namely, fragment, symmetric, and asymmetric antibodies. Fragment bispecific antibodies such as a nanobody DART and BiTE are currently undergoing clinical trials. Likewise, tetravalent BsAb - DVD and DAF symmetric antibodies are under research. Companies such as Sanofi S.A., Merck & Co., Inc. and Genentech, Inc. are conducting research on symmetric bispecific antibodies. BEAT, duobody, and crossmab are examples of asymmetric bispecific antibodies, which are currently being researched by Glenmark Pharmaceuticals, Eli Lilly and Company, and Genmab A/S.

Bispecific antibody (BsAb) is an artificial protein that is composed of fragments of two different monoclonal antibodies and has ability to bind to two different types of antigen. Cancer immunotherapy is the most widely explored application of bispecific antibody. Lung, breast and colon cancer are the wider applications of BsAb. Bispecific antibody simultaneously binds to a cytotoxic cell and target tumor cell and destroys it. Bispecific antibodies are emerging a technologically advanced solution for dual targeting strategies within same molecule.
