AstraZeneca $AZN announced results from a Phase 3 trial assessing its LYNPARZA (olaparib) for the maintenance treatment of platinum-resistant, BRCA mutation-positive ovarian cancer showed treatment with 300 mg twice daily as monotherapy extended progression-free survival (PFS) compared to placebo. The results were clinically meaningful and statistically significant. PFS substantially exceeded what was observed in a Phase 2 study, Study 19, in the same profile of patients.
