The Food and Drug Administration has announced a new approved indication for olaparib (Lynparza) in adults with advanced epithelial ovarian, fallopian tube, or primary peritoneal cancer.
Olaparib is now FDA-approved for use in combination with bevacizumab as maintenance therapy in patients who responded to first-line platinum-based chemotherapy and whose cancer is homologous recombination deficiency positive, as defined by a deleterious or suspected deleterious BRCA mutation and/or genomic instability.
The FDA also approved the Myriad myChoice CDx test as a companion diagnostic for olaparib.
Trial results
The efficacy of olaparib and the myChoice CDx test were assessed in patients in the phase 3 PAOLA-1 trial (NCT02477644). The study enrolled patients with advanced high-grade epithelial ovarian, fallopian tube, or primary peritoneal cancer who had received first-line platinum-based chemotherapy and bevacizumab.
Patients were stratified by first-line treatment outcome and BRCA mutation status, as determined by prospective local testing. All available clinical samples were retrospectively tested with the Myriad myChoice CDx test.
The patients were randomized to receive olaparib at 300 mg orally twice daily in combination with bevacizumab at 15 mg/kg every 3 weeks (n = 537) or placebo plus bevacizumab (n = 269). Patients continued bevacizumab in the maintenance setting and started olaparib 3-9 weeks after their last chemotherapy dose. Olaparib could be continued for up to 2 years or until disease progression or unacceptable toxicity.
The median progression-free survival among the 387 patients with homologous recombination deficiency-positive tumors was 37.2 months in the olaparib arm and 17.7 months in the placebo arm (hazard ratio, 0.33), according to the prescribing information for olaparib.
Serious adverse events occurred in 31% of patients in the olaparib arm. The most common were hypertension (19%) and anemia (17%).
Dose interruptions from adverse events occurred in 54% of patients in the olaparib arm, and dose reductions from adverse events occurred in 41%.
