First in Human Study of CDR404 in HLA-A*02:01 Participants With MAGE-A4 Expressing Solid Tumors

February 26, 2026 updated by: CDR-Life AG

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

CDR404 is a highly potent and specific T-cell engaging bispecific and bivalent antibody designed for the treatment of cancers positive for the tumor-associated antigen melanoma-associated antigen 4 (MAGE-A4). This is a first-in-human study designed to evaluate the safety, tolerability, and preliminary anti-tumor activity of CDR404 in adult patients who have the appropriate germline human leukocyte antigen HLA-A*02:01 tissue marker and whose cancer is positive for MAGE-A4.

Detailed Description

The CDR404-001 Phase 1 study will enrol patients with locally advanced, unresectable or metastatic tumors expressing MAGE-A4, which include advanced solid tumors, and will be conducted in multiple phases:

  1. To identify the maximum tolerated dose (MTD) and pharmacologically effective dose range (PEDR) for CDR404
  2. To assess preliminary evidence of anti-tumor activity of CDR404
  3. To characterise the pharmacokinetics of CDR404
  4. To characterise the immunogenicity of CDR404
  5. To assess translational biomarkers
