About C4 Therapeutics

This clinical-stage biopharmaceutical company focuses on developing targeted protein degradation therapies to address unmet medical needs.

The company also advances early-stage discovery programs directed at inflammation, neuroinflammation, and neurodegenerative conditions, serving patient populations facing severe oncologic and neurological disorders.

The company conducts clinical trials and research activities across multiple territories, with clinical development of CFT8919 underway in Greater China through a partnership, while maintaining development rights for other global regions.
