LONDON, Aug. 03, 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 June 30, 2023.

“We had a successful ASCO conference this quarter, with topline data presentation for obe-cel from the FELIX study highlighting low levels of immunotoxicity combined with a high complete remission rate and excellent CAR T expansion and persistence in adult patients with relapsed/refractory ALL. The attractive clinical profile driven by the unique CAR design combined with robust and reliable manufacturing have been the foundation for the successful outcome of the FELIX study,” commented Dr. Christian Itin, Chief Executive Officer of Autolus. “The Company is now focused on delivering a BLA filing to the US FDA by year end and the initial preparatory activities for a commercial launch in 2024, pending the necessary regulatory approvals.”

“We have also advanced our preparations for a US commercial launch, selecting Cardinal Health as our distribution partner and by putting into place the team that will initiate onboarding of treatment centers in the second half of this year. With our commercial manufacturing facility, The Nucleus, on track to commence Good Manufacturing Practice (GMP) operations in the second half of 2023, we are in a strong position to operationally deliver product and adequately meet the global demand for adult ALL treatment.”  

“Looking beyond ALL and building on the pioneering work by Georg Schett and Andreas Mackensen at the University of Erlangen, we believe obe-cel's excellent safety profile and high level of activity in ALL and NHL patients, combined with our operational infrastructure, forms an attractive basis for development of obe-cel in autoimmune disease with a start of first clinical trial in early 2024.”

Key obe-cel Updates:

• Obecabtagene autoleucel (obe-cel) in relapsed / refractory (r/r) adult ALL – The FELIX Study
  • Pivotal Phase 2 data presented at ASCO and EHA confirmed attractive product profile with potential best-in-class tolerability and very low levels of high-grade CRS and ICANS. Longer term follow up data and subgroup analysis data to be presented at ASH in late 2023, as well as at medical conferences in H1 2024. BLA submission for obe-cel on-track to be submitted to the FDA at the end of 2023.

Obe-cel trials in collaboration with University College London

• Obe-cel in r/r adult 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 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, entitled ‘Dual targeting of CD19 and CD22 against B-ALL using a novel high sensitivity aCD22 CAR.’

Early-stage pipeline – leveraging academic collaborations / opportunity for non-dilutive funding

• AUTO4 in Peripheral T Cell Lymphoma patients – Phase 1/2 LibrA T1 Study
  • Data presented at the International Conference on Malignant Lymphoma (ICML) in an oral presentation titled ‘First in Human Study of AUTO4, a TRBC1-Targetting CAR T Cell Therapy in Relapsed/Refractory TRBC1-Positive Peripheral T-Cell Lymphoma’ demonstrated safety with no dose limiting toxicities and remarkable durability in 2 out of 4 responding patients at the highest dose level tested, with ongoing complete metabolic responses (CMR) in two r/r PTCL patients at 15 and 18 months.

• AUTO8 in Multiple Myeloma – Phase 1 MCARTY Study
  • AUTO8 is a next-generation product candidate for multiple myeloma, which comprises two CARs for the multiple myeloma targets, BCMA and CD19. In collaboration with UCL, the Company initiated a study in Q1 2022. Patients continue to be enrolled and initial data is expected by the end of 2023.

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 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 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 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.
