A one-time, personalized cell therapy from Kyverna Therapeutics improved mobility and reduced disabilities in patients with stiff person syndrome, a rare, neurological autoimmune disorder, according to study results presented Tuesday.
Kyverna intends to submit the treatment to the Food and Drug Administration by the middle of the year. If approved, it would become the first treatment for stiff person syndrome and the first personalized CAR-T therapy for an autoimmune disease of any kind to reach the market.
Currently, CAR-T treatments are approved only for blood cancers, but using engineered T cells to deplete B cells — essentially performing an immune system reset inside a patient — has pushed a growing number of biotech companies to shift their CAR-T focus to autoimmune diseases.
