- Conference call to be held on August 4, 2022 at 8:30 am ET/1:30 pm BST -
LONDON, August 4, 2022 - 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 second quarter ended June 30, 2022.
“Autolus has had a successful second quarter, with progress made across all fronts. We were awarded Regenerative Medicine Advanced Therapy (RMAT) Designation for obecabtagene autoleucel (obe-cel) for the treatment of adult acute lymphoblastic leukemia (ALL) by the US Food and Drug Administration (FDA) in April 2022, showcased cell programming technology at the American Society of Gene and Cell Therapy (ASGCT) meeting in May 2022, and announced first clinical data from four pipeline programs at the European Hematology Association (EHA) congress in June 2022. During this time, we also continued to progress the pivotal Phase 2 FELIX clinical trial of obe-cel in r/r ALL, and the build of our commercial manufacturing site is progressing on schedule.” said Dr. Christian Itin, CEO of Autolus. “Obe-cel continues to show very encouraging activity with a high level of sustained complete remissions in B-NHL patients, without inducing severe CRS or neurotoxicity, and AUTO1/22 reached clinical proof of concept with a high level of activity observed in children with ALL who are not eligible for commercial CAR T therapy. We are particularly excited about AUTO4 reaching clinical proof of concept in patients with T cell lymphoma. We are looking forward to releasing initial results for the FELIX trial in Q4 2022 and are planning updates on our other clinical studies at the end of the year.”
Key Pipeline Updates:
- Obecabtagene autoleucel (obe-cel) in relapsed / refractory (r/r) adult ALL
- The FELIX Phase 2 trial continues to progress well, and Autolus is on track to report initial results from the trial in Q4 2022. The Company continues to expect to report full data in H1 2023, with plans to present this data at a medical conference in mid-2023.
- Following the RMAT designation granted to obe-cel in April 2022 by FDA, Autolus met with the FDA to review the regulatory pathway for obe-cel in r/r ALL. Consistent with prior guidance, and assuming a positive outcome from the FELIX trial in H1 2023, the Company expects the data to form the basis of a planned Biologics License Application (BLA) submission to FDA.
- As previously announced, Autolus initiated a separate cohort of up to 50 additional patients with Minimal Residual Disease (MRD), with the intention of establishing the profile of obe-cel in patients across all levels of disease burden in adult ALL.
Pipeline updates at the European Hematology Congress (EHA), June 2022:
- Obe-cel shows high level of sustained clinical activity in r/r B-NHL patients – ALLCAR19 Extension Trial
- Patients continue to be enrolled into the Phase 1 ALLCAR19 extension trial. The latest data readout from this extension study of obe-cel in patients with r/r B-Cell Non-Hodgkin's Lymphoma (B-NHL) and Chronic Lymphocytic Leukemia (CLL) were presented at EHA in June 2022. In this patient population, obe-cel continues to display a favorable safety profile with no neurotoxicity/immune effector cell-associated neurotoxicity (ICANS) or Grade ≥ 3 Cytokine Release Syndrome (CRS). Long term persistence of obe-cel in the peripheral blood was demonstrated by qPCR. Of the 20 patients evaluable for efficacy, the overall response rate was 18/20 (90%). In the B-NHL cohorts the CRR was 16/17 (94%) (FL: 7/7, MCL: 3/3, DBCL: 6/7). In the CLL cohort 2/3 patients achieved a PR, notably both achieved MRD-negativity in their marrow and both remain in PR at 10 and 6 months respectively. Of the responding MCL, DLBCL, FL and CLL patients, 17/18 (94%) are without disease progression at last follow-up. One MCL patient relapsed six months following treatment and 1 FL patient died in CR from COVID-19. Longer follow-up and enrolment of additional MCL, FL, DLBCL and CLL patients is ongoing.
- Obe-cel shows first activity in Primary CNS Lymphoma – CAROUSEL Trial
- Patients continue to be enrolled into the Phase 1 CAROUSEL trial. Data from the trial were presented at EHA in June 2022, where excellent expansion was observed in the peripheral blood by qPCR, with persistence in all treated patients at last follow-up. No Grade 3 or higher CRS was observed using IV or I-VEN AUTO1 administration. Two cases of Grade 3 ICANS were reported following IV infusion. In the first case the patient had several neurological deficits that evolved despite ICANS treatment and were compatible with progressive PCNSL, as confirmed with the month 1 MRI scan. The second case was a patient whose neurological deficits improved with steroids/anakinra. Encouraging response rates were observed: of 6 patients evaluable for efficacy following IV AUTO1, the ORR was 4/6 (67%), with 2 CRs and 2 PRs. These four responding patients are without disease progression at last follow up. Two patients died from progressive PCNSL on study.
- AUTO1/22 in pediatric ALL demonstrates encouraging and durable responses in children ineligible for commercial CAR T product – CARPALL Trial
- Autolus, in collaboration with UCL, continues to enroll patients into the AUTO1/22 Phase 1 CARPALL trial. The results from 11 treated patients, who were ineligible for receiving commercial CAR T therapy, were presented in an oral presentation at EHA in June 2022. AUTO1/22 has demonstrated a favorable safety profile with no incidences of severe CRS, and one Grade 4 ICANS which was indistinguishable from chemotherapy-related leukoencephalopathy. We have seen excellent CAR T expansion, with only 4 patients losing CAR T persistence at the last follow up. Overall, 9 out of 11 patients achieved a molecular complete response, with 2 non-responders. Notably, 2 out of 3 patients with CD19-negative disease achieved molecular complete response demonstrating the efficacy of the CD22 CAR. Two patients relapsed with CD19+CD22+ disease. No antigen negative relapses were seen in responding patients. At a median follow up of 8.7 months, 6 of 9 responding patients were in MRD-negative complete remission (1-12 months) and the median duration of B-cell aplasia has not been reached.
- AUTO4 shows high level of clinical activity with a novel targeting approach for patients with T Cell Lymphoma – LibrA T1 Trial
- Autolus continues to enroll patients into the AUTO4 Phase 1 clinical trial. Interim Phase 1 data were presented as an oral presentation at EHA in June 2022 from 10 patients with TRBC1-positive r/r T-cell lymphoma (Peripheral T-cell lymphoma Not Otherwise Specified (PTCL-NOS), Angioimmunoblastic T-cell lymphoma (AITL), Anaplastic Large cell lymphoma (ALCL)) in a Phase 1 dose escalation trial. The median prior lines of treatment was 3 (1-5) and three patients had prior stem cell transplantation. After lymphodepletion with Flu/Cy, patients received either 25, 75, 225 or 450 x 106 CAR T cells. AUTO4 demonstrated a tolerable safety profile, with no patient experiencing any dose limiting toxicities, and no ICANS and no Grade 3 or higher infections. CRS was only seen at the highest dose level of 450 x 106 CAR T cells (Grade 3 in 1 patient; Grade 1-2 in 3 patients). As of April 26, 2022, 9 patients were evaluable for efficacy. At the highest dose level 3 of the 3 patients dosed achieved a complete metabolic remission (CMR) at 1 month. 2 of these patients remain in ongoing CMR by PET-CT at Month 3 and 6 respectively, whilst the 3rd relapsed at 3 months.
Other pipeline updates:
- AUTO8 in Multiple Myeloma – MCARTY Trial
- Autolus, in collaboration with UCL, initiated a Phase 1 clinical trial of AUTO8, the Company’s next-generation product candidate for multiple myeloma, in Q1 2022, with the first patient dosed during the quarter. AUTO8 comprises two independent CARs targeting BCMA and CD19 designed to induce deep and durable responses and extend the durability of effect.
- Autolus presented three abstracts at the American Society of Gene & Cell Therapy (ASGCT) meeting in May 2022. The three abstracts focused on Autolus’ modular approach to CAR T product development, using innovative technology to improve our pipeline of precise, controlled and highly active products. The three abstracts covered: 1) enhancing CAR T therapy using constitutively active cytokine receptors, 2) engineering CAR T cells to express a Fas-CD40 to increase its persistence and tumor cytotoxicity and 3) developing a minocycline mediated protein-protein displacement platform to make cell therapies tunable, dose dependent and reversible.
Key Operational Updates during Q2 2022
- The build phase of the Company’s new 70,000 square foot commercial manufacturing facility in Stevenage, UK continues to progress on track with the anticipated schedule. This facility is expected to be ready for Good Manufacturing Practice (GMP) operations by H2 2023 and is designed for a capacity of 2,000 batches per year with the option to expand capacity as needed.
Key Anticipated Clinical Milestones:
- Initial clinical results from the pivotal FELIX Phase 2 trial in Q4 2022 and Autolus plans to present full data at a medical meeting in H1 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 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]
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 & 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]
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.
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.
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.
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.
