Our proprietary technology platforms enable the development of two or more completely different antibody therapeutics to address complex disease biology. MabPair combines two distinct monoclonal antibodies within one drug entity, while our bispecific platform provides a complementary approach to multi-target intervention through a single molecule. MabPair products could offer many advantages over the conventional combination of two individual antibodies.
