LBA29 Final overall survival (OS) results from the phase III PAOLA-1/ENGOT-ov25 trial evaluating maintenance olaparib (ola) plus bevacizumab (bev) in patients (pts) with newly diagnosed advanced ovarian cancer (AOC)

In the PAOLA-1/ENGOT-ov25 (NCT02477644) primary analysis, adding ola to maintenance bev after first-line (1L) platinum-based chemotherapy (PBC) + bev led to a significant progression-free survival (PFS) benefit in AOC (HR 0.59, 95% CI 0.49–0.72; P<0.001), particularly in pts with homologous recombination deficiency (HRD+; BRCA1/2 mutation [BRCAm] and/or genomic instability; Ray-Coquard et al NEJM 2019). Here, we report the prespecified final OS analysis.
