Over the last few years, the evidence has been mounting for the role of DNA repair in prostate cancer. What started with the Stand Up 2 Cancer (SU2C) International Dream Team discovery of 23% homologous recombination repair gene alteration rate in metastatic castration-resistant prostate cancer (mCRPC), followed by the identification of an 11.8% germline alteration rate in metastatic prostate cancer, has now led to broad sweeping successes with the introduction of PARP inhibitors to our clinics.1,2
The TRITON2 trial demonstrated a 43.5% objective response rate with rucaparib in patients with metastatic castration-resistant prostate cancer (mCRPC) and a deleterious BRCA1 or BRCA2 alteration.3 This trial led to the United States Food and Drug Administration (FDA) granting accelerated approval to rucaparib for the
