This study evaluates the safety and effect of the drug CID-078 given on its own in patients with advanced solid tumors. Patients whose disease has progressed on standard therapies, including triple negative breast cancer, small cell lung cancer, or tumors with an RB1 or CDKN2A/B alteration, can take part. It is being conducted in Phase 1 and is still enrolling participants.
The summary above is a plain-language rendering of the official record. The original English title is shown for reference.
