LONDON, Aug. 08, 2024 (GLOBE NEWSWIRE) -- Autolus Therapeutics plc (Nasdaq: AUTL), a clinical-stage biopharmaceutical company developing next-generation programmed T cell therapies, today announces its financial results for the second quarter ended June 30, 2024, and provides additional operation and clinical updates.

“We are focused on driving commercial readiness activities across Autolus to bring our lead product obecabtagene autoleucel (obe-cel) to adult B-ALL patients. Applications for marketing authorizations are under review by regulatory agencies in the US, Europe and UK, and we are working towards a US Food and Drug Administration (FDA) PDUFA target date of November 16, 2024,” said Dr. Christian Itin, Chief Executive Officer of Autolus. “Data from the FELIX Phase 1b/2 study with a median follow up of 21 months presented at ASCO and EHA indicate a long-term plateau forming in event-free and overall survival rates. Stem cell transplant post obe-cel did not appear to improve patient outcomes, and patients with long-term persisting obe-cel appear to have improved event free survival. The data support the potential for obe-cel as a stand-alone therapy in a portion of r/r adult ALL patients.”

Key obe-cel updates and anticipated milestones:

• Obe-cel in r/r adult B-ALL – The FELIX Study
  • In the UK, an MAA was submitted to the MHRA at the end of July 2024. The Biologics License Application (BLA) is on track with the FDA, working towards a Prescription Drug User Fee Act (PDUFA) target action date of November 16, 2024. An MAA submitted to EMA was accepted in April 2024.
  • Pooled analysis of the FELIX Phase 1b/2 study were presented at the American Society of Oncology (ASCO) and European Hematology Association (EHA) annual meetings in June 2024, with a median follow-up of 21 months. Data showed stabilization of event-free survival and overall survival following treatment with obe-cel, with 40% of patients in ongoing remission. Of the 99 responders following treatment with obe-cel, 18 received a subsequent stem cell transplant (SCT) while in minimal residual disease (MRD)-negative response but did not show improved survival compared to patients who did not have a subsequent SCT. Patients with prolonged obe-cel persistence experienced improved event-free survival and data indicate that bridging of high tumor burden patients with inotuzumab could be effective at reducing tumor burden, cytokine release syndrome (CRS) and immune effector cell-associated neurotoxicity syndrome (ICANS) without increasing liver toxicity.
• Obe-cel in B-cell mediated autoimmune diseases
  • The Phase 1 dose confirmation study (CARLYSLE) in refractory systemic lupus erythematosus (SLE) patients is ongoing. Autolus continues to expect initial clinical data in late 2024.
• Pipeline programs in collaboration with University College London
  • Clinical programs AUTO8, AUTO6NG and AUTO1/22 are progressing well and we are planning data updates for all programs in 2025.
    

Operational Updates:

• During the quarter, Autolus promoted the following individuals to Senior Vice President: Andrea Braun, Regulatory Affairs; Markus Gruell, Corporate Quality; Claudia Mercedes Mayer, Manufacturing Strategy and Technology; Chris Gray, Technical Operations and Facilities and Dilip Patel, Market Access and Pricing Strategy. These individuals bring significant leadership experience and continue to drive Autolus’ regulatory activities and preparation for the potential commercialization and launch of obe-cel.
• In April 2024, Autolus announced that the EMA had accepted its MAA for obe-cel for patients with r/r adult B-ALL.
• In April 2024, Autolus entered into a distribution services agreement with a subsidiary of Cardinal Health to support the ordering and distribution of obe-cel in the United States, if it receives regulatory approval.
• In April 2024, Autolus announced the appointment of Mike Bonney as Chairman of the Board, and Ravi Rao M.D. as Non-Executive Director. John H. Johnson stepped down from his roles as Chairman of the Board and Non-Executive Director, effective April 1, 2024.

2024 Expected News Flow:

Financial Results (Unaudited) for the Quarter Ended June 30, 2024

Cash and cash equivalents at June 30, 2024 totaled $705.9 million, as compared to $239.6 million at December 31, 2023.

Total operating expenses, net for the three months ended June 30, 2024 were $58.9 million, as compared to $44.4 million for the same period in 2023.

Research and development expenses increased from $33.2 million to $36.6 million for the three months ended June 30, 2024, compared to the same period in 2023. This change was primarily due to increases in operating costs related to our new manufacturing facility, employee salaries and related costs, and clinical trial and manufacturing costs related to obe-cel, partially offset by an increase in our U.K. reimbursable R&D tax credits that reduce R&D expense.

General and administrative expenses increased from $11.1 million to $21.9 million for the three months ended June 30, 2024, compared to the same period in 2023. This increase was primarily due to salaries and other employment-related costs driven by increased headcount supporting pre-commercialization activities.

Net loss was $58.3 million for the three months June 30, 2024, compared to $45.6 million for the same period in 2023. Basic and diluted net loss per ordinary share for the three months ended June 30, 2024, totaled $(0.22), compared to basic and diluted net loss per ordinary share of $(0.26) for the same period in 2023.

Autolus estimates that, with its current cash and cash equivalents, it is well capitalized to drive the full launch and commercialization of obe-cel in r/r adult B-ALL as well as to advance its pipeline development plans, which includes providing runway to data in the first pivotal study of obe-cel in autoimmune disease.

About obe-cel (AUTO1)
Obecabatagene autoleucel (obe-cel) is a B-lymphocyte antigen CD19 (CD19) chimeric antigen receptor (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 relapsed/refractory (r/r) Adult B-cell Acute Lymphoblastic Leukemia (B-ALL) patients. The results of the FELIX trial, a pivotal trial for adult B-ALL, have been submitted and accepted by the FDA with a PDUFA target action date of November 16, 2024. In the EU a regulatory submission to the EMA was accepted in April 2024, while in the UK, an MAA was submitted to MHRA in July 2024. In collaboration with Autolus’ academic partner, University College London, obe-cel is currently being evaluated in a Phase 1 clinical trial for B-cell non-Hodgkin lymphoma (B-NHL).

About obe-cel FELIX clinical trial
Autolus’ Phase 1b/2 clinical trial of obe-cel enrolled adult patients with r/r 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 complete remission 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 1 clinical trial for patients with r/r pediatric ALL. [NCT02443831]

About AUTO6NG
AUTO6NG is a next generation programmed T cell product candidate in development for the treatment of both neuroblastoma and other GD2-expressing solid tumors. 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. A Phase 1 clinical trial of AUTO6NG in children with relapsed/refractory neuroblastoma was opened for enrollment in the fourth quarter of 2023.

About AUTO8
AUTO8 is a next-generation product candidate for multiple myeloma which comprises two independent CARs for the multiple myeloma targets, B-cell maturation antigen (BCMA) and CD19. We have developed an optimized BCMA CAR designed for improved killing of target cells that express BCMA at low levels. This has been combined with fast off rate CD19 CAR from obe-cel, with the aim of inducing deep and durable responses and extending 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]
