ClinConnect Summary

This clinical trial is looking at a new treatment called TNG456, which is being tested alone and together with another medication called abemaciclib for patients with advanced solid tumors that have a specific change known as MTAP loss. The trial aims to determine how safe these treatments are and how well they can be tolerated by patients. It is open to adults aged 18 and older who have tumors that have not responded well to standard treatments or where standard treatments are not suitable. They must be able to swallow tablets and have certain health criteria met.

Participants in this study will receive TNG456 and may also receive abemaciclib, depending on their condition. The trial is divided into two parts: initially, it will explore different doses of the medications, followed by a phase where it expands to treat specific types of tumors with confirmed MTAP loss. The study aims to include up to 191 participants. If you or a loved one is considering joining, it’s important to know that participants will be closely monitored for safety and the effectiveness of the treatments throughout the study.
