Marengo Therapeutics

Marengo Therapeutics is a Cambridge, Massachusetts clinical-stage biotech reprogramming the immune system from the inside out. Instead of releasing the brakes on T cells the way checkpoint inhibitors do, Marengo's STAR (Selective T Cell Activation Repertoire) platform builds antibody-fusion molecules that target variable regions of the T cell receptor (Vβ) to selectively wake up the specific subsets of T cells that can attack tumors - and remember them. Launched in 2021 with $80M from Apple Tree Partners, its lead drug invikafusp alfa (STAR0602) is in Phase 1/2 trials, has earned FDA Fast Track designation, and is being studied across cancers that no longer respond to PD-1 therapy.
