mRNA-Based CAR T-Cell Therapy Descartes-11 Moves Into Phase 2 Trial in Myeloma

Multiple myeloma is the second most common hematological malignancy in the world and remains difficult to treat despite numerous therapeutic advances and drug approvals.

Patients continue to experience multiple relapses and complications of the disease, affecting many areas of the body, such as the bones, kidneys and immune system.

An mRNA-based CAR-T cell therapy, named Descartes-11, has been developed as a consolidative therapy in newly diagnosed high-risk multiple myeloma patients who have residual disease after the first treatment. Descartes-11 is engineered to express CAR molecules transiently rather than permanently, which may reduce some of the short- and long-term risks associated with traditional autologous CAR-T cell therapies.

This therapy is one of the first mRNA-based cancer treatment to enter clinical development. Phase 1 data showed no evidence of cytokine release syndrome or neurotoxicity in patients with advanced multiple myeloma. Currently, the emergence of these adverse events remains a major challenge for CAR-T cell therapies in hematological malignancies. The Phase 2 trial (NCT04436029) will enroll approximately 30 patients with newly diagnosed multiple myeloma who remain weakly positive for residual disease after initial treatment.
