Evaluating a new cancer treatment using brenetafusp for advanced solid tumors

Phase 1/2 Study of IMC-F106C in Advance PRAME-Positive Cancers

Phase1; Phase2 Interventional Immunocore Ltd · NCT04262466

This study is testing a new cancer treatment called brenetafusp to see if it can safely help people with advanced solid tumors that have a specific marker.

What this trial studies

This clinical trial investigates the safety and efficacy of brenetafusp (IMC-F106C), an immune-mobilizing monoclonal T cell receptor designed to target cancers expressing the PRAME antigen. The study is divided into two phases: Phase 1 focuses on determining the maximum tolerated dose of brenetafusp as a standalone treatment and in combination with other therapies, while Phase 2 assesses its effectiveness in patients with advanced solid tumors. Participants must have the HLA-A2 tissue marker and a PRAME-positive tumor, and they will be monitored for safety and treatment outcomes.

Who should consider this trial

Good fit: Ideal candidates include adults with advanced solid tumors who are HLA-A*02:01 positive and have PRAME-positive tumors.

Not a fit: Patients with untreated central nervous system metastasis or significant ongoing health issues may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could provide a new therapeutic option for patients with advanced solid tumors that express the PRAME antigen.

How similar studies have performed: While this approach is novel, similar immunotherapy strategies have shown promise in treating various cancers, indicating potential for success.
