Summary

This early-stage trial is testing a new oral drug called ISM6331 in 100 adults with advanced mesothelioma or other solid tumors that have not responded to standard treatments. The study aims to find a safe dose and check for any early signs that the drug can shrink tumors. Participants take one capsule daily, and researchers will monitor side effects and how the drug moves through the body.

What this could lead to

If successful, this could point toward a new treatment option for people with advanced mesothelioma or other solid tumors who have run out of standard therapies.

What could go wrong

This is a very early Phase 1 trial with only 100 participants, so the drug may not prove safe or effective. Side effects are unknown, and it may not work for all tumor types.
