AUTL Autolus Therapeutics PLC

Autolus Therapeutics plc (Nasdaq: AUTL), a clinical-stage biopharmaceutical company developing next-generation programmed T cell therapies, today announces that the European Medicines Agency (EMA) has accepted the Company’s Marketing Authorization Application (MAA) for obecabtagene autoleucel (obe-cel). Obe-cel is Autolus’ lead investigational chimeric antigen receptor (CAR) T cell therapy, for the treatment of patients with relapsed/refractory (r/r) adult B-cell Acute Lymphoblastic Leukemia (ALL). The MAA submission was based on data from the pivotal Phase 2 FELIX study of obe-cel in adult r/r B-ALL.

Autolus’ Nucleus site has recently received the formal certification from the MHRA following a full inspection of the site in February 2024. The MHRA issued two new GMP certificates to cover both clinical and commercial manufacture from the site.

“Along with the recent acceptance of the BLA by the FDA, the acceptance of our EU marketing application is an important milestone in expanding into the European market and delivering this potentially transformative therapy to B-ALL patients,” commented Dr. Christian Itin, Chief Executive Officer of Autolus. “We look forward to working with the EMA throughout the evaluation process of obe-cel, and thank the internal team at Autolus for their work on the submission and Nucleus site inspection."

Obe-cel has been granted Orphan Drug Designation by the FDA, Orphan Medical Product Designation by the EMA, Regenerative Medicine Advanced Therapy (RMAT) designation by the FDA and PRIority MEdicines (PRIME) designation by the EMA for adult r/r B-ALL.

About obe-cel (AUTO1)Obe-cel is a CD19 CAR T cell investigational therapy designed to overcome the limitations in clinical activity and safety compared to current CD19 CAR T cell therapies. Obe-cel is designed with a fast target binding off-rate to minimize excessive activation of the programmed T cells. In clinical trials of obe-cel, this “fast off-rate” profile reduced toxicity and T cell exhaustion, resulting in improved persistence and leading to high levels of durable remissions in r/r Adult ALL patients. The results of the FELIX trial, a pivotal trial for adult ALL, have been submitted and accepted by the FDA with a PDUFA target action date of November 16, 2024, and a filing has also been accepted by the EMA. In collaboration with Autolus’ academic partner, UCL, obe-cel is currently being evaluated in a Phase 1 clinical trials for B-NHL.

About obe-cel FELIX clinical trialAutolus’ Phase 1b/2 clinical trial of obe-cel enrolled adult patients with relapsed / refractory B-precursor ALL. The trial had a Phase 1b component prior to proceeding to the single arm, Phase 2 clinical trial. The primary endpoint was overall response rate, and the secondary endpoints included duration of response, MRD negative CR rate and safety. The trial enrolled over 100 patients across 30 of the leading academic and non-academic centers in the United States, United Kingdom and Europe. [NCT04404660].
