What this Trial Is About

Researchers are studying ISM6331, an investigational drug, in adults with advanced or metastatic malignant mesothelioma or other solid tumors who have limited treatment options. This Phase 1, open-label, multicenter trial aims to assess the safety, tolerability, recommended dose for further study, how the drug is processed in the body, and early signs of anti-tumor activity. The trial includes two parts: dose escalation to find safe dosing levels, and dose selection to optimize treatment dose.
