“Building on the therapeutic impact that PARP inhibitors have had over the last several years, we believe this new PARP1 program, if successful, could fill a significant unmet need for patients unresponsive to existing PARP inhibitors with an improved hematological adverse event profile,” said Victoria Zazulina, M.D., Head of Development Unit, Oncology, for the Healthcare business of Merck KGaA, Darmstadt, Germany. “The work of NMS to discover and advance this next generation PARP1 selective inhibitor coupled with our deep expertise in developing therapies which modify DNA damage response mechanisms, creates a strong foundation to further develop this investigational therapy for patients.”
