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.
