New drug combo targets Hard-to-Treat prostate cancer
NCT ID NCT07115446
First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This early-stage trial is testing two experimental drugs together in men with advanced prostate cancer that has worsened after standard hormone therapy. HS-20093 is an antibody-drug conjugate that targets a protein on cancer cells, while HRS-5041 is a drug that breaks down androgen receptors. The study will enroll 63 participants to find the safest dose and check for side effects.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- HS-20093 (an antibody-drug conjugate) and HRS-5041 (a protein degrader targeting androgen receptors)
- What this could lead to
- If successful, this could point toward a new treatment option for men with advanced prostate cancer that has stopped responding to standard hormone therapy.
- What could go wrong
- This is an early phase 1 trial with only 63 participants, so it is primarily testing safety and dosing. The combination may not work well or could cause unexpected side effects.
