(UroToday.com) The 2022 EAU annual meeting featured a game changing session, including a discussant presentation by Dr. Juan Gomez Rivas discussing exploratory endpoints from PROpel, a phase III trial of abiraterone + olaparib versus abiraterone + placebo in first-line mCRPC. Dr. Gomez Rivas notes that there is an evolving treatment paradigm for prostate cancer. Among patients diagnosed with localized prostate cancer, 90% of those patients are treated with radiotherapy, surgery or active surveillance, leading to a cure in ~75% of those patients, with the remaining 25% being treated with androgen deprivation therapy (ADT) in the setting of biochemical recurrence. Among these patients, a proportion will develop M0 castration resistant prostate cancer (CRPC), for which the SPARTAN trial,1 PROSPER trial,2 and ARAMIS trial3 demonstrated a survival benefit vs placebo for apalutamide, enzalutamide, and darolutamide, respectively. For patients that have metastatic castration sensitive prostate cancer (mCSPC), docetaxel (CHAARTED,4 STAMPEDE5), abiraterone (LATITUDE,6 STAMPEDE7), enzalutamide (ARCHES,8 ENZAMET9), and apalutamide (TITAN10) have all improved survival. However, patients may progress to require additional treatments in the M1 CRPC setting, including several additional lines of therapy:
