CAR-T Cell Therapies Show Promise for Severe Autoimmune Diseases at EULAR 2025
- Multiple CAR-T cell therapies targeting CD19-positive B cells demonstrated clinical efficacy across severe autoimmune diseases including systemic lupus erythematosus, systemic sclerosis, and rheumatoid arthritis at EULAR 2025.
- Resecabtagene autoleucel achieved deep B cell depletion and clinical responses in patients with systemic sclerosis, idiopathic inflammatory myopathy, and lupus, with patients remaining free of immunosuppressive therapy.
- Novel approaches including dual CD19/BCMA targeting CAR-T cells and off-the-shelf iPSC-derived CAR-T therapies showed favorable safety profiles with no severe cytokine release syndrome or neurotoxicity.
- Early data suggest CAR-T therapy can reset the immune system in multiple rheumatic and musculoskeletal diseases, allowing patients to achieve sustained remission without ongoing immunosuppression.
