Autolus Therapeutics Unveils Promising CAR-T Therapy Data
Overview of Presentation at ACR Convergence 2025
Autolus Therapeutics plc (Nasdaq: AUTL), a pioneering biopharmaceutical company known for developing innovative T cell therapies, presented exciting updates during a recent scientific session at the American College of Rheumatology Convergence 2025. The spotlight was on data from the Phase 1 CARLYSLE study, which investigates the potential of a novel therapy, obe-cel, for patients suffering from severe refractory systemic lupus erythematosus (srSLE).
Highlights from the CARLYSLE Study
Preliminary findings from the CARLYSLE trial indicate that obe-cel has an encouraging safety profile, with no reported cases of severe cytokine release syndrome (CRS) or neurotoxicity. The study highlights the administration of a 50 million cell dose, which has shown promising responses in patients previously unresponsive to other treatments.
Among those participating in the study, 83% achieved a definition of remission in their disease, while half of the patients showed a complete renal response. Impressively, all these results were sustained without any new disease activity observed at a median follow-up of 8.9 months.
Details on Patient Responses
Participants in the study included individuals with refractory lupus nephritis, a severe manifestation of lupus. Among six patients treated, several experienced significant improvement in their kidney function, and notably, four had previously impaired kidney health. Importantly, none were undergoing additional lupus-directed therapies during the study, with glucocorticoid doses gradually reduced for better health management.
“The CARLYSLE study demonstrates the therapeutic potential of obe-cel in offering significant clinical benefits to those afflicted by severe lupus, often devoid of effective treatment avenues,” stated Dr. Maria Leandro, a senior consultant rheumatologist involved with the study.
Future Directions for Autolus Therapeutics
Autolus is keen on advancing its clinical research with plans to initiate the Phase 2 trial for patients with active lupus nephritis by the end of 2025. The company is currently collaborating with the U.S. FDA to hone in on the trial design and overall pathway toward potential regulatory approval.
Dr. Christian Itin, CEO of Autolus, remarked, “These encouraging results lay a solid groundwork as we move forward into the LUMINA trial. Our history in treating acute leukemia patients with CAR T therapies gives us confidence in potentially being the first to market with an effective therapy for srSLE patients.”
