LONDON, May 17, 2024 (GLOBE NEWSWIRE) -- Autolus Therapeutics plc (Nasdaq: AUTL), a clinical-stage biopharmaceutical company developing next-generation programmed T cell therapies, today announces its operational and financial results for the first quarter ended March 31, 2024.

“We continue to engage with the FDA in the regulatory review process for obecabtagene autoleucel (obe-cel) in adult ALL as we head towards the PDUFA target action date of November 16, 2024, and are driving commercial readiness activities across the Company," said Dr. Christian Itin, Chief Executive Officer of Autolus. “We’re also delighted that our abstracts from the pivotal FELIX Phase 2 trial have been accepted for oral presentations at ASCO and EHA this year and we look forward to sharing further long-term data and additional subset analyses.”

“In addition, the first two patients have been enrolled into our dose confirmation trial (CARLYSLE) of obe-cel in Systemic Lupus Erythematosus (SLE) and the study is on track for initial data by end of 2024.”

Key obe-cel updates and anticipated milestones:

• Obe-cel in relapsed / refractory (r/r) adult B-cell Acute Lymphoblastic Leukemia (ALL) – The FELIX Study
  • Obe-cel Biologics License Application (BLA) for r/r B-ALL submitted to the FDA in November 2023; PDUFA target action date of November 16, 2024. A marketing authorization application (MAA) to the European Medicines Agency (EMA) was accepted in April 2024. For the UK we are evaluating a filing based on an international recognition procedure.
  • Pooled analysis of the FELIX Phase 1b/2 study presented at ASH in December 2023 demonstrated prolonged event free survival and low overall immunotoxicity across all cohorts in r/r B-ALL, and particularly in patients with low leukemic burden at lymphodepletion.
  • Further long-term data from the FELIX study including additional subset analysis will be presented in oral and poster presentations at the American Society of Clinical Oncology annual meeting (ASCO – May 31 – June 4, 2024), and European Hematology Association congress (EHA – June 13 – 16, 2024) respectively.

• Obe-cel in B-cell mediated autoimmune diseases
  • The Phase 1 dose confirmation study (CARLYSLE) in refractory systemic lupus erythematosus (SLE) patients is ongoing. Two patients have been enrolled and Autolus continues to expect initial clinical data in late 2024.

Pipeline clinical trials, in collaboration with University College London (UCL), updates and anticipated milestones:

• AUTO8 in Multiple Myeloma – Phase 1 MCARTY Study
  • AUTO8 is a next-generation product candidate for multiple myeloma, which includes two CARs for the multiple myeloma targets, BCMA and CD19. Initial data from the MCARTY Phase 1 study in multiple myeloma presented at ASH in December 2023 showed AUTO8 was well tolerated, with responses observed in all patients. Enrollment of the initial cohorts are complete and further updates from the MCARTY study are anticipated in H2 2024.

• AUTO6NG in Neuroblastoma – Phase 1 MAGNETO Study
  • AUTO6NG contains a CAR that targets GD2 alongside additional programming modules to enhance the activity and persistence. A Phase 1 clinical study in children with r/r neuroblastoma was opened for enrollment in the fourth quarter of 2023.

2024 Expected News Flow:

Financial Results (Unaudited) for the Quarter Ended March 31, 2024

Cash and cash equivalents at March 31, 2024, totaled $758.5 million, as compared to $239.6 million at December 31, 2023.

Total operating expenses, net for the three months ended March 31, 2024, were $38.8 million, as compared to $39.1 million, for the same period in 2023.

Research and development expenses increased from $27.4 million to $30.7 million for the three months ended March 31, 2024, compared to the same period in 2023. This change was primarily due to increases in operating costs related to the Company’s new commercial manufacturing facility, employee salaries and related costs, clinical trial costs related to obe-cel, and a decrease in our U.K. reimbursable R&D tax credits claimable through the U.K. small and medium-sized entity (SME) scheme. These were partially offset by decreases in professional consulting fees, legal fees, manufacturing costs related to obe-cel clinical supply, information technology infrastructure fees and general office expenses.

General and administrative expenses increased from $9.3 million to $18.2 million for the three months ended March 31, 2024, compared to the same period in 2023. This increase was primarily due to salaries and other employment-related costs driven by an increase in general and administrative headcount supporting the overall growth of the business, primarily relating to pre-commercialization activities.

Net loss was $52.7 million for the three months ended March 31, 2024, compared to $39.8 million for the same period in 2023. The basic and diluted net loss per ordinary share for the three months ended March 31, 2024, totaled $(0.24), compared to a basic and diluted net loss per ordinary share of $(0.23) for 2023.

Autolus estimates that, with its current cash and cash equivalents and proceeds received from the strategic alliance with BioNTech and the private placement and underwritten equity financing, it is well capitalized to drive the full launch and commercialization of obe-cel in r/r adult 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)
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. A regulatory submission to the EMA was accepted in April 2024. 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 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]

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 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, 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]
