About the DuoBody Platform
The DuoBody platform is an innovative platform for the discovery and
development of bispecific antibodies that may improve antibody therapy of
cancer, autoimmune, infectious and central nervous system disease. Bispecific
antibodies bind to two different epitopes either on the same, or on different
targets (also known as dual-targeting) which may improve the antibodies'
specificity and efficacy in inactivating the disease targets. DuoBody
molecules are unique in combining the benefits of bispecificity with the
strengths of conventional antibodies which allows DuoBody molecules to be
administered and dosed as other antibody therapeutics. Genmab's DuoBody
platform generates bispecific antibodies via a fast and broadly applicable
process which is easily performed at standard bench, as well as commercial,
manufacturing scale.
