CRISPR Therapeutics Reports Positive Phase 1 Data for Zugo-cel in Autoimmune Diseases
CRISPR Therapeutics has provided an update on zugocabtagene geleucel (zugo-cel), its investigational allogeneic CAR T cell therapy, in a Phase 1 basket trial for refractory rheumatologic autoimmune diseases. The trial includes patients with systemic lupus erythematosus (SLE), systemic sclerosis (SSc), and idiopathic inflammatory myopathy (IIM). As of October 15, 2026, 21 patients have been dosed across these cohorts: four with SLE, eight with SSc, and nine with IIM. Data presented at ACR Convergence 2026 showed promising results, particularly in SSc patients, where 83% (5/6) receiving standard lymphodepletion achieved a clinical response (rCRISS-25) at Month 3, with all responders maintaining their response. Additionally, all nine IIM patients achieved a moderate or major Total Improvement Score (TIS) response. The company reported that Zugo-cel was well tolerated across all 21 patients, with no cytokine release syndrome (CRS) above Grade 2 and no immune effector cell-associated neurotoxicity syndrome (ICA...
