Management of Adverse Events During Rucaparib Treatment for Relapsed Ovarian Cancer: A Review of Published Studies and Practical Guidance

The poly(ADP-ribose) polymerase inhibitor rucaparib is approved as monotherapy in the treatment and maintenance settings for women with relapsed ovarian cancer in the European Union and the United States. We review the safety profile of rucaparib in both settings and provide recommendations for the clinical management of the main adverse events (AEs) that may occur during rucaparib treatment. We searched PubMed and congress proceedings for safety data on oral rucaparib monotherapy (600 mg twice daily) from clinical trials involving patients with relapsed ovarian cancer. AE management guidance was developed from clinical trial protocols, rucaparib prescribing information, oncology association guidelines, and author experience. The most frequent any-grade treatment-emergent AEs (TEAEs) included gastrointestinal symptoms, asthenia/fatigue, dysgeusia, anemia/decreased hemoglobin, and increased alanine/aspartate aminotransferase. Across clinical trials, 61.8% of patients had one or more grade 3 or higher TEAEs. Clinicians should employ close follow-up for TEAEs, particularly early in treatment, and educate patients about expected TEAEs and methods for their monitoring and management (e.g., antiemetics for nausea/vomiting, transfusions for hematologic TEAEs, or dose interruptions/reductions for moderate/severe TEAEs). Overall, 16.2% of patients discontinued rucaparib due to TEAEs. Management of AEs that may occur during rucaparib treatment is crucial for patients to obtain optimal clinical benefit by remaining on therapy and to avoid their detrimental impact on quality of life.
