Progression-Free Survival Improves in DUO-E Trial: AZ
AstraZeneca says the Phase 3 DUO-E trial showed statistically significant and clinically meaningful improvement in progression-free survival of advanced endometrial cancer when its Imfinzi (durvalumab) was used in combination with platinum-based chemotherapy and followed by Imfinzi plus Lynparza (olaparib) or Imfinzi alone as maintenance therapy. A company announcement says there was a greater benefit observed with the combination of Imfinzi and Lynparza as maintenance therapy.
Imfinzi is described as a human monoclonal antibody that binds to the PD-L1 protein and blocks the interaction of PD-L1 with the PD-1 and CD80 proteins. It is the only approved immunotherapy for unresectable Stage 3 non-small-cell lung cancer in patients whose disease has not progressed after chemotherapy. It also is approved in the U.S. to treat extensive-stage small-cell lung cancer.
Lynparza is a first-in-class PARP inhibitor and the first targeted treatment to block DNA damage response in cells/tumors harboring a deficiency in homologous recombination-related genes. It is approved in several countries for use with several tumor types.
