LONDON, Nov. 02, 2023 (GLOBE NEWSWIRE) -- Autolus Therapeutics plc (NASDAQ:AUTL), a clinical-stage biopharmaceutical company developing next-generation programmed T cell therapies, today announced its operational and financial results for the quarter ended September 30, 2023.

"The coming months will be an exciting and instrumental time for Autolus as we plan for our first BLA submission for obe-cel with the US FDA by year end and we continue with our preparatory activities for a planned commercial launch in 2024, pending the necessary regulatory approvals," said Dr. Christian Itin, Chief Executive Officer of Autolus. "The data we have observed to date in the FELIX study highlights the potential of obe-cel to deliver a high complete remission rate combined with low levels of immunotoxicity and excellent CAR T expansion and persistence in adult patients with relapsed/refractory ALL. We look forward to building on the positive data when we present longer term follow up and additional subgroup analysis data at ASH in December."

"Alongside this, our commercial manufacturing facility, The Nucleus, completed process performance qualification activities in Q4 to support the BLA submission, and we believe we are in a strong position operationally to deliver product and meet the global demand for adult ALL treatment."

"Obe-cel's excellent risk/benefit profile combined with its ability to make deep cuts into the CD19+ cell compartment, as illustrated by MRD-negative complete remissions in adult and pediatric ALL patients, is a strong foundation for the development of obe-cel in autoimmune disease. The clinical profile together with our commercial product delivery base, attractive cost of goods, and commercial infrastructure should help to drive an accelerated and differentiated expansion of the obe-cel opportunity. We are excited at the growing body of evidence that CAR T can address a significant unmet need in autoimmune disease, and we look forward to starting a Phase I study of obe-cel in refractory systemic lupus erythematosus (SLE) patients in early 2024."

About Autolus Therapeutics plc

Autolus is a clinical-stage biopharmaceutical company developing next-generation, programmed T cell therapies for the treatment of cancer and autoimmune disease. Using a broad suite of proprietary and modular T cell programming technologies, the Company is engineering precisely targeted, controlled and highly active T cell therapies that are designed to better recognize target cells, break down their defense mechanisms and eliminate these cells. Autolus has a pipeline of product candidates in development for the treatment of hematological malignancies, solid tumors and autoimmune diseases. For more information, please visit www.autolus.com.

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]

About AUTO1/22

AUTO1/22 is a novel dual targeting CAR T cell-based therapy candidate based on obe-cel. It is designed to combine the enhanced safety, robust expansion and persistence seen with the fast off rate CD19 CAR from obe-cel with a high sensitivity CD22 CAR to reduce antigen negative relapses. This product candidate is currently in a Phase I clinical trial for patients with r/r pediatric ALL. [NCT02443831]

About AUTO6NG

AUTO6NG is a next generation programmed T cell product candidate in pre-clinical development. AUTO6NG builds on preliminary proof of concept data from AUTO6, a CAR targeting GD2-expression cancer cell currently in clinical development for the treatment of neuroblastoma. AUTO6NG incorporates additional cell programming modules to overcome immune suppressive defense mechanisms in the tumor microenvironment, in addition to endowing the CAR T cells with extended persistence capacity. AUTO6NG is currently in pre-clinical development for the potential treatment of both neuroblastoma and other GD2-expressing solid tumors.

About AUTO8

AUTO8 is a next-generation product candidate for multiple myeloma which comprises two independent CARs for the multiple myeloma targets, BCMA and CD19. We have developed an optimized BCMA CAR which is designed for improved killing of target cell that express BCMA at low levels. This has been combined with fast off rate CD19 CAR from obe-cel. We believe that the design of AUTO8 has the potential to induce deep and durable responses and extend the durability of effect over other BCMA CARs currently in development. This product candidate is currently in a Phase I clinical trial for patients with r/r multiple myeloma. [NCT04795882]
