Modifying patients’ T-cells with mRNA to express a chimeric antigen receptor (rCAR-T therapy), a novel approach to treat myasthenia gravis and other autoimmune diseases.
Gaithersburg, MD—June 22, 2023 – Cartesian Therapeutics, a clinical-stage biotechnology company pioneering cell therapies for autoimmune diseases, announced today the publication of a landmark paper in The Lancet Neurology. The study describes Descartes-08, a cutting-edge RNA CAR-T (rCAR-T) therapy administered to patients with generalized myasthenia gravis (MG), a debilitating autoimmune neurological disease. The data demonstrate marked and long-lasting clinical improvement in patients with MG. This is the first clinical trial using rCAR-T to treat autoimmunity, and the first successful Phase 2 trial using an engineered cell therapy to treat autoimmunity.
