What this trial studies

This Phase 1 clinical trial evaluates the safety and efficacy of BH3120, both as a standalone treatment and in combination with pembrolizumab, for patients with advanced or metastatic solid tumors. The study consists of a dose-escalation phase to determine the maximum tolerated dose (MTD) and a dose-expansion phase to assess the potential efficacy of the treatment at the recommended dose. Participants will be monitored for safety, tolerability, pharmacokinetics, and overall response to the treatment.

Who should consider this trial

Good fit: Ideal candidates include adults with confirmed metastatic or unresectable solid tumors that express PD-L1 and have not received prior anti-4-1BB therapy.

Not a fit: Patients with active CNS metastases, chronic liver disease, or those who have experienced severe toxicities from prior immunotherapy may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide a new treatment option for patients with advanced solid tumors who have no available standard therapies.

How similar studies have performed: Other studies have shown promise with similar immunotherapy approaches, but this specific combination is being explored for the first time.
