Olaparib Tablet: A Review in Ovarian Cancer Maintenance Therapy

Abstract

Olaparib (Lynparza®), a first-in-class poly (ADP-ribose) polymerase (PARP) inhibitor, has recently been approved in a new tablet formulation as maintenance treatment for recurrent high-grade epithelial ovarian, fallopian tube, or primary peritoneal cancer in patients who are in complete or partial response to platinum-based chemotherapy. Relative to an earlier capsule formulation, the tablet formulation of olaparib has improved bioavailability, thereby reducing pill burden and offering a more convenient dosage regimen. In the phase III SOLO2 study, maintenance treatment with olaparib tablets significantly prolonged median PFS (primary endpoint) relative to placebo in patients with platinum-sensitive, recurrent, ovarian cancer bearing gBRCA mutations. Results from an earlier phase II study (Study 19) assessing the capsule formulation supported these findings, with a significant PFS benefit (primary endpoint) observed with olaparib relative to placebo as maintenance therapy in patients with platinum-sensitive, recurrent, ovarian cancer, with or without BRCA mutations. Olaparib tablet had a manageable tolerability profile, with most adverse events of mild or moderate severity. Given its efficacy and manageable tolerability profile, olaparib tablets provide a useful maintenance treatment option for recurrent, platinum-sensitive ovarian cancer, regardless of BRCA mutation status, with the tablet formulation providing a more convenient dosing option.
