Flag Therapeutics

Founded in 2013 and headquartered in Raleigh, North Carolina, FLAG Therapeutics, Inc is an early-stage oncology company focused on the development of therapies based on two investigational product platforms: the Anti-angiogenic & Anti-tubulin (AA/AT) platform and Purine Synthesis Inhibitor (PSI) platform.

These two platforms comprise thousands of investigational water-soluble small molecule compounds designed to target and destroy cancer cells through well-established mechanisms of action. Preclinical studies suggest that these investigational compounds hold the potential to treat multiple cancer types with greater efficacy and tolerability than observed in conventional therapies.

FLAG Therapeutics obtained exclusive worldwide rights to the technology from Duquesne University in November 2013, including a robust patent estate currently comprising 58 issued patents and 42 pending applications covering both matter composition and compound use.
