Dr Petrylak’s research interests span both prostate and bladder cancers. He currently serves as the principal investigator or coprincipal investigator for 9 SWOG clinical trials on genitourinary cancers. He has led the Advanced Bladder Cancer Subcommittee for SWOG since 1995, as well as multiple national and international studies on prostate and bladder cancers. He led an investigator-initiated trial of docetaxel and estramustine in castration-resistant prostate cancer. The results of this study supported a phase 3 SWOG trial of this combination led by Dr Petrylak that, in turn, supported the US Food and Drug Administration approval of docetaxel for castration-resistant prostate cancer. This was one of the first two trials to demonstrate a survival benefit in this state of disease. Dr Petrylak has also been instrumental in the development of immunotherapy and targeted therapies for refractory bladder cancer. His work with Enfortumab Vedotin has supported the accelerated approval of this drug
