Summary

This trial aims to test a new drug called (R)-9bMS in patients with advanced prostate cancer. The drug has shown promising results in preclinical studies by suppressing tumor growth and activating the immune

Who is the study for?
This trial is for adults with metastatic castration-resistant prostate cancer. Participants must have a confirmed diagnosis and may not have had previous treatments that would conflict with the study drug. The trial excludes individuals who cannot take oral medication or have conditions that could interfere with the study outcomes.
What is being tested?
(R)-9bMS, an ACK1 inhibitor taken orally twice daily, is being tested in this Phase I trial to evaluate its safety and effectiveness against prostate cancer. The study will also determine the maximum tolerated dose and observe any potential anti-tumor responses over a period including treatment and follow-up.
What are the potential side effects?
Potential side effects of (R)-9bMS are currently under investigation in this Phase I trial. Common side effects from similar medications include digestive issues, fatigue, skin reactions, blood disorders, but specific side effects related to (R)-9bMS will be determined based on observed adverse events during the trial.
