What this trial studies

This Phase 1 interventional study evaluates the safety and dosage of STM-416p when administered intraoperatively to patients undergoing radical prostatectomy for prostate cancer. The study aims to determine the appropriate dose escalation of STM-416p in a controlled setting. Participants will be closely monitored for any adverse effects and the efficacy of the treatment in conjunction with the surgical procedure. The study focuses on males with confirmed prostate cancer scheduled for surgery within a specific timeframe.

Why it matters

Potential benefit: If successful, this treatment could improve outcomes for patients undergoing radical prostatectomy by enhancing the effectiveness of the surgery.

How similar studies have gone: While this approach is novel, similar studies exploring intraoperative treatments for cancer have shown promise in enhancing surgical outcomes.
