Testing IMC-R117C for advanced cancers in specific patients

A Phase 1/2 First-in-Human Study of the Safety and Efficacy of IMC-R117C (PIWIL1 × CD3 ImmTAC® Bispecific Protein) as a Single Agent and in Combination in HLA-A*02:01-Positive Participants With Selected Advanced PIWIL1-Positive Cancers

PHASE1; PHASE2 · Immunocore Ltd · NCT06840119

This study is testing a new treatment called IMC-R117C to see if it can help people with advanced cancers like colorectal, esophageal, gastric, or ovarian cancer who have already tried other therapies.

What this trial studies

This phase 1/2 study aims to evaluate the safety and effectiveness of IMC-R117C, a bispecific protein, in patients with advanced cancers who are HLA-A*02:01-positive. Participants will receive IMC-R117C either alone or in combination with other cancer therapies, including chemotherapy and kinase inhibitors. The study focuses on individuals with advanced colorectal, esophageal, gastric, or ovarian carcinoma who have previously undergone standard treatments. The trial will assess the response of measurable disease using established criteria.

Who should consider this trial

Good fit: Ideal candidates are HLA-A*02:01-positive individuals with advanced colorectal, esophageal, gastric, or ovarian carcinoma who have a good performance status.

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 cancers that are currently difficult to treat.

How similar studies have performed: Other studies using bispecific proteins have shown promise, suggesting potential for success in this novel approach.
