Novel Ways of Targeting the Androgen Receptor – Summary
Daniel P. Petrylak, MD, explores novel approaches for targeting the androgen receptor (AR) in prostate cancer, highlighting that around 90% of prostate cancer specimens express the androgen receptor, which persists through castrate resistance.
In this 7-minute talk, Dr. Petrylak focuses on targeting the AR ligand-binding domain with molecules known as proteolysis-targeting chimeras (PROTACs). Laboratory findings reveal that PROTACs can degrade AR variants resistant to traditional therapies like enzalutamide, showing efficacy against androgen gene amplification mutations.
He shares that ARV-110, a PROTAC developed for clinical use, showed promise in phase 1 trials with castration-resistant prostate cancer patients. However, due to significant side effects, the ARV-110 trials were abandoned in favor of a newer compound, ARV-766. While ARV-110 has demonstrated efficacy in castration-resistant prostate cancer, ARV-766 offers a broader range of AR degradation with improved patient tolerance, making it the preferred candidate for continued clinical evaluation.
The Future Directions in Urology Symposium (FDUS) is an annual urology think tank and non-CME educational summit that brings together industry figures and experts to discuss the current state of genitourinary care and define future directions in treatment. Dr. Dreicer delivered this educational activity during the 24th iteration of the meeting in August 2024 in Colorado Springs, Colorado.
