Prostate cancer has entered the era of precision medicine with the introduction of PARP inhibitors for patients with specific mutations in genes associated with DNA damage repair. Recent studies have shown benefit in combination therapy with PARP inhibitors like olaparib and antiandrogens like abiraterone.
This review discusses the pharmacodynamics and pharmacokinetics of olaparib as well as the data supporting combination therapy with olaparib and abiraterone.
Co-targeting the androgen receptor and PARP pathway has shown clear clinical benefit in the management of patients with metastatic castration resistant prostate cancer and mutations in BRCA1, BRCA2 and ATM. The benefit in patients without these mutations is less clear and the benefit of olaparib combination therapy in the management of hormone sensitive disease remains to be seen.
