New Dual-Action antibody takes on Hard-to-Treat cancers
NCT ID NCT04140500
First seen Jun 27, 2026 · Last updated Sep 11, 2026 · Updated 1 time
Summary
This early-phase study tests a new drug, RO7247669, that targets two immune system checkpoints (PD-1 and LAG-3) to help the body fight cancer. About 170 adults with advanced solid tumors (including melanoma, lung cancer, and esophageal cancer) who have run out of standard options will receive the drug. The main goals are to find the safest dose and see if the drug can shrink tumors.
