Testing CDR404 for advanced solid tumors with specific markers

Phase 1, First-in-Human Study to Assess the Safety, Tolerability and Anti-tumor Activity of CDR404 in HLA-A*02:01 Participants With MAGE-A4 Expressing Solid Tumors

PHASE1 · CDR-Life AG · NCT06402201

This study is testing a new treatment called CDR404 for patients with advanced solid tumors that have a specific marker to see how safe it is and how well it works.

What this trial studies

This clinical trial evaluates CDR404, a bispecific antibody designed to target MAGE-A4 expressing solid tumors in patients with the HLA-A*02:01 tissue marker. It aims to determine the maximum tolerated dose and pharmacologically effective dose range of CDR404 while assessing its safety, tolerability, and preliminary anti-tumor activity. The study will also characterize the pharmacokinetics and immunogenicity of CDR404 and evaluate translational biomarkers in participants with advanced solid tumors that are relapsed, refractory, or intolerant to standard therapies.

Who should consider this trial

Good fit: Ideal candidates include adults with advanced solid tumors that express MAGE-A4 and have the HLA-A*02:01 marker.

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

Why it matters

Potential benefit: If successful, this treatment could provide a new targeted therapy option for patients with specific advanced solid tumors.

How similar studies have performed: While this approach is novel, similar studies targeting specific tumor-associated antigens have shown promise in early phases.
