New antibody drug targets Hard-to-Treat cancers in early trial
NCT ID NCT06402201
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This early-phase trial tests a new drug called CDR404 in up to 42 adults with advanced solid tumors that have a specific marker (MAGE-A4) and tissue type (HLA-A*02:01). The drug is designed to help the body's immune T-cells find and attack cancer cells. The main goals are to check safety, find the right dose, and see if the drug can shrink tumors.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- CDR404 (a bispecific antibody that engages T-cells to attack cancer cells)
- What this could lead to
- If it works, this could point toward a new treatment option for certain hard-to-treat solid tumors that express the MAGE-A4 protein.
- What could go wrong
- This is a very early, first-in-human trial with only 42 participants, so safety and effectiveness are not yet known. The treatment may cause side effects or fail to shrink tumors.
