Autolus Therapeutics Announces FDA RMAT Designation Granted to Obe-cel for the Treatment of Systemic Lupus Erythematosus and Lupus Nephritis

LONDON and GAITHERSBURG, Md., Sept. 09, 2026 (GLOBE NEWSWIRE) -- Autolus Therapeutics plc (Nasdaq: AUTL), a commercial-stage biopharmaceutical company developing, manufacturing and delivering next-generation programmed T cell therapies and candidates, today announced that the U.S. Food and Drug Administration (FDA) has granted regenerative medicine advanced therapy (RMAT) designation to obecabtagene autoleucel (obe-cel) for the treatment of systemic lupus erythematosus (SLE) and lupus nephritis (LN).

RMAT designation is a program created under the 21st Century Cures Act to accelerate the development and regulatory review of regenerative medicine therapies, including cell therapies, intended to treat serious or life-threatening diseases.

Dr. Matthias Will, Chief Development Officer of Autolus, said: “SLE and LN are serious autoimmune diseases with a critical unmet need for new therapeutic options, particularly for patients with severe refractory disease. We are grateful to have received the RMAT designation for obe-cel based on the Phase 1b data reported from the CARLYSLE trial and believe it provides an important framework to facilitate efficient development within the LUMINA trial. We look forward to continuing to work closely with the FDA as we advance obe-cel through clinical development.”

The next data update from the Phase 1 CARLYSLE trial in patients with SLE has been submitted for presentation at the American College of Rheumatology (ACR) Annual Meeting in the fourth quarter of 2026. LUMINA, the pivotal Phase 2 study of obe-cel in patients with refractory LN, continues enrolling in five countries and Autolus expects to report data in 2028.
