Study Summary

This trial is testing a new drug, CLN-619, to see if it can shrink tumors when used alone or with another drug, pembrolizumab.

Who is the study for?
Adults with advanced solid tumors, including specific types such as NSCLC, cervical cancer, HNSCC, and urothelial carcinoma. Participants must have measurable disease, acceptable organ function and performance status. Prior treatments are specified for each cohort. Pregnant or breastfeeding women and those unwilling to prevent pregnancy or donate sperm during the study are excluded.Check my eligibility
What is being tested?
The trial is testing CLN-619 alone and combined with Pembrolizumab in patients with various advanced solid tumors. It's an early-phase (Phase 1), open-label study which means both researchers and participants know what treatment is being given.See study design
What are the potential side effects?
Potential side effects may include typical reactions associated with immunotherapy such as inflammation of organs, infusion-related reactions, fatigue, possible immune system complications like pneumonitis or colitis, liver issues meeting Hy's Law criteria.
