Headquartered in Cambridge, Massachusetts, the company focuses on engineering monoclonal antibody candidates designed to enhance T cell–mediated anti‐tumor responses. Compass leverages proprietary antibody platforms to identify and optimize biologics that modulate immune checkpoint pathways and the tumor microenvironment. The company’s lead programs include CTX-471, a bispecific antibody targeting both PD-1 and PD-L1 checkpoints, and DSP107, a CD47‐SIRPα pathway modulator aimed at disrupting “don’t eat me” signals on cancer cells. Both assets have advanced into clinical development, with ongoing studies evaluating safety, pharmacodynamics and preliminary efficacy across multiple tumor types. Compass also maintains a rich preclinical pipeline of next‐generation antibody constructs designed to address checkpoint resistance and immune suppression in solid tumors. Compass Therapeutics employs an integrated discovery and development model, combining in‐house antibody engineering capabilities with translational science and biomarker analysis. The company collaborates with academic institutions and contract research organizations to streamline the advancement of its molecules from lead optimization through early‐phase clinical trials. This approach supports rapid iteration and selection of candidates with differentiated mechanisms of action. Founded in 2018, Compass Therapeutics is led by President and Chief Executive Officer Ravi Mohan, Ph.D., whose experience spans immuno-engineering and oncology drug development. While primarily focused on the U.S. market, the company is positioned to pursue global clinical collaborations and strategic partnerships as its clinical programs mature.AI Generated.
