Parthenon Therapeutics is inventing a novel class of anti-cancer therapies that reprogram the tumor microenvironment (TME). The interplay between cancer cells and their surrounding microenvironment is relevant in drug development as many cancers use the TME to build barriers that shield immune system attack. One approach, PRTH-101, breaks these barriers to overcome recalcitrant cancers. Based on rigorous, groundbreaking research, we are designing a portfolio of drug candidates to treat the right patients at the right time.
