Scott Koenig, M.D., Ph.D., President and CEO of MacroGenics, said “Finally, we have determined that the results of the TAMARACK Phase 2 study of vobra duo in mCRPC do not support additional financial investment by MacroGenics. We believe the B7-H3 target continues to have potential and are pleased with the progress being made with our alternate anti-B7-H3 ADC, MGC026.”
