• PDUFA Goal date is November 16, 2024
• Company on track to submit a marketing authorization application to the European Medicines Agency (EMA) in the first half of 2024

LONDON, Jan. 22, 2024 (GLOBE NEWSWIRE) -- Autolus Therapeutics plc (Nasdaq: AUTL), a clinical-stage biopharmaceutical company developing next-generation programmed T cell therapies, today announces that the U.S. Food and Drug Administration (FDA) has accepted its Biologics License Application (BLA) for obecabtagene autoleucel (obe-cel) for patients with relapsed/refractory (r/r) Adult B-Cell Acute Lymphoblastic Leukemia (ALL). Under the Prescription Drug User Fee Act (PDUFA), the FDA has set a target action date of November 16, 2024, a standard review timeline consistent with recently approved CAR T therapies. The FDA is not currently planning to hold an advisory committee meeting to discuss this application.

The BLA submission is based on data from the Pivotal Phase 2 FELIX study of obe-cel in adult r/r B-ALL. The data were presented at the 2023 American Society of Clinical Oncology (ASCO) Annual Meeting in June 2023, with updated data presented at the Annual Meeting of the American Society for Hematology Meeting (ASH) in December 2023.

“Acceptance of the BLA filing is an important milestone for Autolus and we look forward to continuing our collaboration with the FDA during the review cycle,” commented Dr. Christian Itin, Chief Executive Officer of Autolus. “With the PDUFA date set for November, we remain focused on preparing for the potential launch of obe-cel.”

Autolus plans to submit a Marketing Authorization Application for obe-cel in relapsed/refractory ALL to the European Medicines Agency (EMA) in the first half of 2024.

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. Clinical trials of obe-cel have demonstrated that this “fast off-rate” profile reduces 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, are being prepared for regulatory submissions with the FDA and EMA. Autolus is conducting a Phase 1b study in paediatric patients with ALL and aggressive B-NHL and iIn collaboration with UCL, obe-cel is currently being evaluated in a Phase 1 clinical trials for B-NHL.

About obe-cel FELIX clinical trial

Autolus’ Phase Ib/II clinical trial of obe-cel enrolled adult patients with relapsed / refractory B-precursor ALL. The trial had a Phase Ib component prior to proceeding to the single arm, Phase II clinical trial. The primary endpoint is overall response rate, and the secondary endpoints include 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]
