About the company

We are a late clinical-stage biopharmaceutical company focused on pioneering a new class of precision medicines for the treatment of immune-mediated diseases and cancer. Our novel approach targets signal regulatory proteins (SIRP), a family of cell surface receptors whose expression is restricted to specific immune cell populations, and increases upon activation to enable selective depletion of disease-driving cells while preserving normal immune function. By replacing broad immunosuppression with selective elimination of principal cells that drive disease, we believe our approach can do for immune-mediated diseases what precision oncology has done for cancer, transforming the treatment paradigm for patients. To our knowledge, we are the first company to advance this SIRP-targeted precision immune cell depletion approach into clinical development and demonstrate proof-of-concept in humans.
