“Half of patients with metastatic triple-negative breast cancer (TNBC) achieved disease control when treated with the combination of a poly (ADP-ribose) polymerase (PARP) inhibitor and an anti–PD-1 agent, a preliminary prospective study showed.
“Overall, 13 of 46 evaluable patients had objective responses to treatment with niraparib (Zejula) and pembrolizumab (Keytruda). An additional 10 patients had stable disease. Clinical activity was observed in patients beyond those with germline BRCA mutations.”
