Gedatolisib in Combination With Darolutamide in Metastatic Castration-Resistant Prostate Cancer

This is a Phase 1/2, open-label, randomized, dose finding and dose expansion study to evaluate the safety, preliminary efficacy, and pharmacokinetics of gedatolisib, a pan-PI3K/mTOR inhibitor, in combination with darolutamide, a next-generation androgen receptor inhibitor, in patients with metastatic castration-resistant prostate cancer following progression on a next-generation androgen receptor inhibitor. The aim of the Phase 1 portion of the study is to evaluate dose limiting toxicities and to determine the recommended Phase 2 dose. The aim of the Phase 2 portion of the study is to further assess the safety and preliminary efficacy of the drug combination.
