MacroGenics, Inc. has announced that the U.S. Food and Drug Administration (FDA) has lifted the partial clinical hold on its Phase 1 monotherapy and combination studies of MGD009, a B7-H3 × CD3 bispecific DART molecule. Enrollment of new patients in the U.S. has been cleared to proceed with these trials. The company previously announced on December 7, 2018, that the FDA had placed the program on partial clinical hold following MacroGenics’ reporting of hepatic adverse events on the MGD009 trials to the FDA. During the partial clinical hold, previously enrolled study participants were allowed to continue to receive drug at their pre-assigned dose.
