CREATE Medicines

CREATE Medicines is a Cambridge, Massachusetts clinical-stage biotech building in vivo immune programming - therapies that use an mRNA-lipid nanoparticle platform to turn a patient's own T cells, NK cells, and myeloid cells into chimeric antigen receptor (CAR) cells directly inside the body, rather than extracting and re-engineering them in a lab. Formerly Myeloid Therapeutics, the company rebranded in October 2025 as its pipeline expanded beyond myeloid cells and cancer into autoimmune disease and fibrosis. Its repeat-dosable, off-the-shelf approach aims to make CAR therapy cheaper and more scalable than conventional cell therapy, and the company says it has dosed more than 50 patients - among the largest clinical datasets for in vivo CAR to date.
