ZÜRICH--(BUSINESS WIRE)--CDR-Life today announced significant clinical progress in its M-gager® portfolio for solid tumors, marking important milestones in the company’s mission to deliver innovative, antibody-fragment based immunotherapies for difficult-to-treat cancers.
First patient dosed with CDR404
The first patient was dosed with CDR404, a novel, bispecific and bivalent antibody fragment-based T cell engager (TCE) targeting MAGE-A4, an intracellular cancer-specific protein that is cleaved into smaller peptide fragments and presented on HLA-A*02:01 molecules at the surface of cancer cells.
The Phase 1 study (NCT06402201) is enrolling HLA-A *02:01+ patients with MAGE-A4+ solid cancers in the U.S. and Europe. The trial is evaluating the safety, tolerability and preliminary anti-tumor activity of CDR404 in several common cancers including squamous cell carcinomas in which MAGE-A4 is highly enriched.
New clinical candidate targeting PRAME
Preferentially Expressed Antigen in Melanoma (PRAME) is a tumor-specific therapeutic target that is expressed in a wide range of solid tumors including lung, ovarian, melanoma, and endometrial cancers, while exhibiting only minimal expression in healthy tissues.
CDR-Life has identified and characterized an antibody fragment-based TCE as a clinical candidate targeting PRAME called CDR813. This TCE binds potently and bivalently to an HLA-A*02-restricted PRAME peptide on the surface of cancer cells. Pre-clinical studies have shown that CDR813 has very favorable pharmacological and manufacturability properties with best-in-class potential for the clinic.
A poster will be presented at the 2024 European Society for Medical Oncology (ESMO) Congress, in Barcelona, Spain.

“The clinical advancement of CDR404 and the excellent progress we have made in advancing CDR813 into a clinically viable drug are significant milestones in our quest to develop life-changing, antibody fragment-based cancer medicines for patients with the HLA-A*02:01 genotype, the most prevalent HLA genotype in the U.S. and Europe, using our proprietary M-gager technology," said Swethajit Biswas, Chief Medical Officer of CDR-Life. “This current suite of T cell engagers targeting cancer-specific peptides presented on HLA underscores our ambitions in solid tumor oncology to create an innovative pipeline of highly specific and potent antibody fragment-based molecules targeting a wide range of cancer-specific antigens including challenging cell surface resident proteins, which are known to be directly involved in tumor growth.”
