• BLA submission includes results from pivotal Phase 2 FELIX study evaluating obe-cel in relapsed/refractory (r/r) adult B-cell Acute Lymphoblastic Leukemia (ALL)
  • Company on track to submit a marketing authorization application to the European Medicines Agency (EMA) in the first half of 2024

LONDON, UK I November 27, 2023 I Autolus Therapeutics plc (Nasdaq: AUTL), a clinical-stage biopharmaceutical company developing next-generation programmed T cell therapies, today announces that it has submitted a Biologics License Application (BLA) to the U.S. Food and Drug Administration (FDA) 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 BLA submission is based on data from the Pivotal Phase 2 FELIX study of obe-cel in adult r/r B-ALL. The data which were presented at the 2023 American Society of Clinical Oncology (ASCO) Annual Meeting in June 2023 and will be updated at the upcoming Annual Meeting of the American Society for Hematology Meeting in December in San Diego.

“We are looking forward to continuing working with the FDA through the regulatory approval process,” commented Dr. Christian Itin, Chief Executive Officer of Autolus. “I would like to thank the treating physicians, patients, caregivers, and the dedicated team at Autolus for their support, trust and commitment for the program to reach this important milestone.”

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. 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 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]
