LONDON, March 14, 2024 (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 full year ended December 31, 2023.

“We’re delighted to be starting 2024 in such a strong financial position; our recently announced strategic alliance with BioNTech, coupled with two equity financing transactions, raised gross proceeds of $600 million. Combined with our 2023 ending cash of $240 million, this enables us to drive the full launch and commercialization of obe-cel in r/r adult ALL and establish Autolus as a potential leader in the delivery of CAR T therapy to patients with autoimmune diseases,” said Dr. Christian Itin, Chief Executive Officer of Autolus.

“2023 was a transformational year for the Company. Our lead program, obe-cel, demonstrated strong data in B-ALL in the pivotal FELIX study, we fully validated our commercial manufacturing facility, The Nucleus, to support our regulatory submissions and we submitted our first BLA for obe-cel to the United States Food and Drug Administration (FDA) in November, with a PDUFA target action date of November 16, 2024. We also just submitted an MAA to the European Medicines Agency (EMA).

“Beyond B-ALL, we see a significant opportunity for obe-cel in autoimmune disease. Our Phase 1 dose confirmation trial in refractory SLE is now open for enrollment. We believe obe-cel’s clinical profile, together with our commercial product delivery base and infrastructure, will help to drive an accelerated and differentiated expansion in autoimmune diseases and we look forward to sharing initial data from the study in late 2024.

“For now, we remain fully focused on preparing for a potential obe-cel launch and successfully transitioning Autolus to a commercial stage company. Pre-commercial and product delivery activities are well underway, and we are on track to make obe-cel available to B-ALL patients as soon as possible, following a potential approval.”

Key obecabtagene autoleucel (obe-cel) updates and anticipated milestones:

• Obe-cel in relapsed / refractory (r/r) adult ALL – The FELIX Study
  • Obe-cel 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 just submitted and an MAA submission to the MHRA in the UK is planned for the second half of 2024.
  • 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. Additionally, data from a pooled analysis from the ALLCAR19 study and FELIX Phase 1b in r/r B-ALL showed durable remissions with obe-cel as a stand-alone therapy in a subset of patients after a median follow up of >3 years. Further long-term data from the FELIX study is anticipated at medical conferences in 2024.
    
    
• Obe-cel in B-cell mediated autoimmune diseases
  
  • The Phase 1 dose confirmation study in refractory systemic lupus erythematosus (SLE) patients has the first site open for enrollment; initial clinical data expected 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. Further updates from the MCARTY study are anticipated during 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 Full Year Ended December 31, 2023

Cash and cash equivalents at December 31, 2023 totaled $239.6 million, as compared to $382.4 million at December 31, 2023.

Total operating expenses, net for the year ended December 31, 2023, were $179.7 million, as compared to $143.4 million, for the year ended December 31, 2022.

Research and development expenses increased from $117.4 million to $130.5 million for the year ended December 31, 2023, compared to the same period in 2022. This change was primarily due to increases in operating costs related to the Company’s new commercial manufacturing facility, contractual milestone payments and employee salaries and related costs, a decrease in our U.K. reimbursable R&D tax credits claimable through the U.K. small and medium-sized entity (SME) scheme and partially offset by decreases in clinical and manufacturing costs related to the Company’s obe-cel clinical product candidate.

In prior years, Autolus reported the R&D tax credits as income tax benefit on its statements of operations. The Company has revised its financial presentation, including the prior years, and will now present such tax credits as a reduction in research and development expense. As a result, income tax benefit has reduced by $19.5 million and $24.6 million for the years ended December 31, 2023, and 2022, respectively, with corresponding reductions in research and development expenses and total operating expenses.

General and administrative expenses increased from $31.9 million to $46.7 million for the year ended December 31, 2023, compared to the same period in 2022. 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 attributable to ordinary shareholders was $208.4 million for the year ended December 31, 2023, compared to $148.8 million for the same period in 2022. The basic and diluted net loss per ordinary share for the year ended December 31, 2023, totaled $(1.20), compared to a basic and diluted net loss per ordinary share of $(1.57) for 2022.

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 made in the first half of 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]
