Gedatolisib and Darolutamide for Metastatic Prostate Cancer

This study is testing a combination of two drugs, gedatolisib and darolutamide, for men with metastatic castration-resistant prostate cancer (mCRPC). This is prostate cancer that has spread and is no longer responding to standard hormone therapy. Gedatolisib works by targeting specific pathways (PI3K and mTOR) that can help cancer grow, while darolutamide is a drug that blocks male hormones. The study aims to find the safest and most effective dose of these drugs together (Phase 1) and then see how well they shrink tumors or slow their growth (Phase 2). You may be eligible if you are an adult male with mCRPC that has progressed after other hormone treatments. The study is currently recruiting about 54 participants.

Study design
This is a Phase 1/2, open-label, randomized study designed to find the right dose and then evaluate the effectiveness of gedatolisib in combination with darolutamide. It plans to enroll 54 participants.
What's involved
Not specified in the trial record.
Compensation
Not stated in the trial record.
Follow-up
Safety will be followed until 30 days after the last dose of study medication. Tumor response will be assessed at 6 months in Phase 2.
