On Oct. 1, 2024, the FDA began implementing a reorganization impacting many parts of the agency. We are in the process of updating FDA.gov content to reflect these changes.

FDA approved olaparib (LYNPARZA, AstraZeneca Pharmaceuticals LP) for the maintenance treatment of adult patients with deleterious or suspected deleterious germline or somatic BRCA-mutated (gBRCAm or sBRCAm) advanced epithelial ovarian, fallopian tube or primary peritoneal cancer who are in complete or partial response to first-line platinum-based

On December 19, 2018, the Food and Drug Administration approved olaparib (LYNPARZA®, AstraZeneca Pharmaceuticals LP) for the maintenance treatment of adult patients with deleterious or suspected deleterious germline or somatic BRCA-mutated (gBRCAm or sBRCAm) advanced epithelial ovarian, fallopian tube or primary peritoneal cancer who are in complete or partial response to first-line platinum-based chemotherapy. Patients with gBRCAm advanced epithelial ovarian, fallopian tube or primary peritoneal cancer should be selected for therapy based on an FDA-approved companion diagnostic.

Approval was based on SOLO-1 (NCT01844986), a randomized, double-blind, placebo-controlled, multi-center trial that compared the efficacy of olaparib with placebo in patients with BRCA-mutated (BRCAm) advanced ovarian, fallopian tube, or primary peritoneal cancer following first-line platinum-based chemotherapy. Patients were randomized (2:1) to receive olaparib tablets 300 mg orally twice daily (n=260) or placebo (n=131).

The primary efficacy outcome was investigator-assessed progression-free survival (PFS) evaluated according to Response Evaluation Criteria in Solid Tumors (RECIST) 1.1. The trial demonstrated a statistically significant improvement in investigator-assessed PFS for olaparib compared to placebo. Estimated median PFS was not reached in the olaparib arm and was 13.8 months in the placebo arm (HR 0.30; 95% CI: 0.23-0.41; p<0.0001). At the time of the analysis of PFS, overall survival data were not mature.

Most common (≥10%) adverse reactions of any grade occurring in patients who received olaparib in SOLO-1 were nausea, fatigue, abdominal pain, vomiting, anemia, diarrhea, upper respiratory tract infection/influenza/nasopharyngitis/bronchitis, constipation, dysgeusia, decreased appetite, dizziness, neutropenia, dyspepsia, dyspnea, urinary tract infection (UTI), leukopenia, thrombocytopenia, and stomatitis.

FDA also approved the ­­­­BRACAnalysis CDx test (Myriad Genetic Laboratories, Inc.) to identify patients with germline BRCA mutated (gBRCAm) advanced epithelial ovarian, fallopian tube or primary peritoneal cancer who are eligible for olaparib. The effectiveness of the ­­­­BRACAnalysis CDx test was based on the SOLO-1 trial population for whom deleterious or suspected deleterious gBRCAm status was confirmed with either prospective or retrospective testing with the ­­­­BRACAnalysis CDx test.

The recommended olaparib dose is 300 mg (two 150 mg tablets) taken orally twice daily, with or without food, for a total daily dose of 600 mg.
