LONDON, May 04, 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 March 31, 2023.

“It has been a busy quarter as we continue to execute on delivering on our obe-cel strategy in order to bring this innovative and potentially transformative treatment to an underserved adult Acute Lymphoblastic Leukemia (ALL) patient population,” said Dr. Christian Itin, Chief Executive Officer of Autolus. “We look forward to presenting data from all patients treated in the FELIX study in an oral presentation at the 2023 American Society of Clinical Oncology (ASCO) Annual Meeting, as well as data at the European Hematology Association (EHA) 2023 Congress, both in June, with longer term follow up data expected at the American Society of Hematology (ASH) meeting at the end of the year.”

“Meanwhile, we continue to advance plans for the submission of a BLA for obe-cel at the end of the year and working towards commercial launch in 2024, subject to required regulatory approval. Post period end we selected Cardinal Health as the US commercial distribution partner for obe-cel and we continue to build out our own commercial infrastructure as we look to on-board centers over the course of this year. Our purpose-built commercial manufacturing facility is on track for the commencement of Good Manufacturing Practice (GMP) operations in H2 2023 with an initial capacity of up to 2,000 batches per year, which we predict will be sufficient to serve global demand in adult ALL.”

Key obe-cel Updates:

• Obecabtagene autoleucel (obe-cel) in relapsed / refractory (r/r) adult ALL – The FELIX Study
  • Oral presentations of the FELIX pivotal study to be presented at ASCO and EHA. The Company expects data from the FELIX study to form the basis of a BLA submission for obe-cel to the FDA at the end of 2023 and plans to present longer term follow up data and subgroup analysis data at the American Society of Hematology (ASH) meeting in late 2023, as well as at medical conferences in H1 2024.

Obe-cel trials in collaboration with University College London

• Obe-cel in r/r adult B-ALL patients – Phase 1 ALLCAR19 Study
  • Long term follow-up data were presented at the Tandem Meetings: Transplantation & Cellular Therapy Meetings of the American Society for Transplantation and Cellular Therapy (ASTCT) and the Center for International Blood & Marrow Transplant Research (CIBMTR). The data demonstrated that 35% of adult B-ALL patients remained in complete remission at a median follow up of 36 months without the need for additional anti-leukemia therapy.

• Obe-cel in r/r B-NHL and CLL patients – Phase 1 ALLCAR19 Extension Study
  • Data presented at the ASH meeting in December 2022 demonstrated the potentially best-in-class profile of obe-cel supported by the data observed in B-cell non-Hodgkin lymphoma (NHL), with continued high levels of clinical activity paired with an encouraging tolerability profile across diffuse large B-cell lymphoma (DLBCL), mantle cell lymphoma (MCL), follicular lymphoma (FL) and chronic lymphocytic leukemia (CLL). Patients continue to be enrolled into the study and the Company expects to publish the full results in a peer-reviewed journal.

• Obe-cel in Primary CNS Lymphoma patients – Phase 1 CAROUSEL Study
  • Data presented at the EHA meeting in June 2022 demonstrated first activity in primary CNS lymphoma. The study is fully enrolled, and the Company expects to publish the full results in a peer-reviewed journal.

• AUTO1/22 in pediatric B-ALL patients – Phase 1 CARPALL Study
  • Data presented at the European Society for Blood and Marrow Transplantation (EBMT) Annual Meeting in April 2023 by the Company’s UCL collaborators, showed favorable safety profile and good efficacy in a heavily pre-treated cohort of patients. Importantly, there were no observed antigen negative relapses observed as of the data cut-off date, indicating that the combining of our optimized CD22 CAR design with the CD19 CAR used in obe-cel may be effective in preventing antigen-loss driven relapse in pediatric B-ALL. The preclinical data supporting this program was published in Molecular Therapy in March 2023.

Financial Results for the First Quarter Ended March 31, 2023

Cash and cash equivalents and restricted cash at March 31, 2023, totaled $343.4 million, as compared to cash of $382.8 million at December 31, 2022.

Net total operating expenses for the three months ended March 31, 2023, were $43.1 million, which included license revenue income of $1.3 million, as compared to net total operating expenses of $41.8 million, which included grant income of $0.2 million, for the same period in 2022.

Research and development expenses decreased by $2.7 million to $31.3 million for the three months ended March 31, 2023 from $34.0 million for the three months ended March 31, 2022 primarily due to:

• a decrease of $5.5 million in clinical trial and manufacturing costs which is offset by an increase of $0.8 million in manufacturing material costs due to increased validation activities undertaken, primarily relating to our obe-cel clinical product candidate,
• a decrease of $0.2 million in depreciation and amortization related to property, plant and equipment and intangible assets due to the reduction in our depreciable asset base,
• a decrease of $0.1 million in legal fees and professional consulting fees in relation to our research and development activities,
• an increase of $1.4 million in salaries and other employment related costs including share-based compensation expense, which was mainly driven by an increase in the number of employees engaged in research and development activities,
• an increase of $0.7 million related to information technology infrastructure and support for information systems related to the conduct of clinical trials and manufacturing operations, and
• an increase of $0.2 million in facilities costs related to our new manufacturing facility, the "Nucleus", in Stevenage, United Kingdom as well increase in costs related to maintaining our current leased properties.

General and administrative expenses increased by $1.3 million to $9.3 million for the three months ended March 31, 2023 from $8.0 million for the three months ended March 31, 2022 primarily due to:

• an increase of $0.7 million in salaries and other employment related costs including share-based compensation expenses, which was mainly driven by an increase in the number of employees engaged in general and administrative activities,
• an increase of $0.7 million in commercial readiness costs due to increased commercial readiness activities being undertaken,
• an increase of $0.1 in general office supplies and expenses facilities costs due to the increase in space utilized for general and administrative activities,
• a decrease of $0.2 million primarily related to a reduction in directors' and officers' liability insurance premiums, legal and professional fees.

For the three months ended March 31, 2023, we recognized a loss on disposal of property and equipment of $3.8 million related to fixed assets no longer being utilized in the manufacturing facility exited in Stevenage, United Kingdom. There were no such disposals for the three months ended March 31, 2022.

Other income, net decreased to $0.8 million from $0.9 million for the three months ended March 31, 2023 and 2022, respectively. The decrease of $0.1 million is primarily due to the recognition of a lease termination loss arising from the termination and exit of one of our manufacturing suites in Stevenage, United Kingdom.

Interest income increased to $3.4 million for the three months ended March 31, 2023, as compared to $28,000 for the three months ended March 31, 2022. The increase in interest income of $3.4 million primarily relates to the increase in interest rates on our interest-bearing bank accounts and short-term investments during the three months ended March 31, 2023 as compared to the three months ended March 31, 2022.

Interest expense increased to $4.9 million for the three months ended March 31, 2023 as compared to $1.8 million for the three months ended March 31, 2022. Interest expense is primarily related to the liability for future royalties and sales milestones, net associated with our strategic collaboration agreement with Blackstone.

Net loss attributable to ordinary shareholders was $39.8 million for the three months ended March 31, 2023, compared to $37.1 million for the same period in 2022. The basic and diluted net loss per ordinary share for the three months ended March 31, 2023, totaled $(0.23) compared to a basic and diluted net loss per ordinary share of $(0.41) for the three months ended March 31, 2022.

Autolus estimates that its current cash and cash equivalents on hand and anticipated future milestone payment from Blackstone will extend the Company’s runway into 2025.

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. Designed to have a fast target binding off-rate to minimize excessive activation of the programmed T cells, obe-cel may reduce toxicity and be less prone to T cell exhaustion, which could enhance persistence and improve the ability of the programmed T cells to engage in serial killing of target cancer cells. In collaboration with Autolus’ academic partner, UCL, obe-cel is currently being evaluated in a Phase 1 clinical trials for B-NHL. Autolus has progressed obe-cel to the FELIX trial, a pivotal trial for adult ALL.

About obe-cel FELIX clinical trial

Autolus’ Phase 1b/2 clinical trial of obe-cel is enrolling 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 is overall response rate, and the secondary endpoints include duration of response, MRD negative CR rate and safety. The trial is designed to enroll approximately 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 AUTO4

AUTO4 is a programmed T cell product candidate in clinical development for T cell lymphoma, a setting where there are currently no approved programmed T cell therapies. AUTO4 is specifically designed to target TRBC1 derived cancers, which account for approximately 40% of T cell lymphomas, and is a complement to the AUTO5 T cell product candidate, which is in pre-clinical development.

About AUTO5

AUTO5 is a programmed T cell product candidate in pre-clinical development for T cell lymphoma, a setting where there are currently no approved programmed T cell therapies. AUTO5 is specifically designed to target TRBC2 derived cancers, which account for approximately 60% of T cell lymphomas, and is a complement to the AUTO4 T cell product candidate currently in clinical development.

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 our 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.
