Conference|ASCO Genitourinary Cancers Symposium

Axel Merseburger, MD, PhD, spoke key results of the PRESIDE trial, which examined continuous enzalutamide to treat patients with metastatic castration-resistant prostate cancer and progressive disease.

In an interview with CancerNetwork® during the 2022 Genitourinary Cancers Symposium, Axel Merseburger, MD, PhD, chairman of the Clinic of Urology at University Hospital Schleswig-Holstein in Lübeck, Germany, discussed the PRESIDE trial (NCT02288247) of enzalutamide (Xtandi) vs matched placebo plus docetaxel and prednisone for men with progressive metastatic castration-resistant prostate cancer. The study was conducted to determine a continued benefit of the androgen receptor inhibitor after disease progression.

Transcript:

The PRESIDE trial showed the clinical benefit of continuing enzalutamide to post-progression [treatment]. This trial was a randomized phase 3b trial in advanced metastatic castration-resistant prostate cancer, with the primary end point progression-free survival [PFS].

Besides the primary end point of PFS which was met with a 28% benefit for the combination of enzalutamide, docetaxel, and prednisone compared with the placebo, docetaxel, and prednisone [HR, 0.72; 95% CI, 0.53-0.96; P = .027]. We could demonstrate that there was a greater decrease in PSA from baseline to week 13 in the enzalutamide group at –37.12% compared with 9.11% in the placebo group.
