Autolus Therapeutics Presents Initial AUTO3 Clinical Data from Phase 1/2
Clinical Trials in B cell Malignancies at the 60th ASH Annual Meeting
- Initial results were presented from ongoing Phase 1/2 trials in pediatric
acute lymphoblastic leukemia (AMELIA trial) and diffuse B cell lymphoma
(ALEXANDER trial) -
LONDON, December 2, 2018 -- Autolus Therapeutics plc (Nasdaq: AUTL), a
clinical-stage biopharmaceutical company developing next-generation programmed
T cell therapies, today highlighted updated results from its ongoing Phase 1/2
AMELIA clinical trial of AUTO3 in patients with relapsed/refractory pediatric
acute lymphoblastic leukemia (pALL) and its ongoing Phase 1/2 ALEXANDER
clinical trial in patients with relapsed/refractory diffuse large B cell
lymphoma (DLBCL) presented at the 60th American Society of Hematology (ASH)
Annual Meeting, San Diego, California. AUTO3 is a dual-targeted therapy
incorporating two separate chimeric antigen receptors (CARs). Observations
from preclinical studies indicate that AUTO3 independently targets CD19 and
CD22. AUTO3 is designed to reduce relapse driven by antigen loss, a key defense
mechanism used by the tumor cells and the primary cause of relapse in pALL.
"The preliminary results of the AMELIA trial indicate that AUTO3, the first
dual targeting CD19 and CD22 CAR T cell therapy under development for pediatric
ALL, appears to have a manageable safety profile, with the potential to
overcome target-negative relapse, a major limitation of current CD19-targeted
therapies," said Professor Persis Amrolia, lead investigator and Consultant in
Bone Marrow Transplant at Great Ormond Street Hospital (GOSH) and NIHR Research
Professor of Transplantation Immunology at UCL Great Ormond Street Institute of
Child Health (ICH).
"In the ALEXANDER trial, preliminary results indicate that AUTO3 followed by
consolidation with a limited duration of anti-PD1 therapy appears to have a
manageable safety profile at the doses evaluated. This is the first therapy
that aims to address two emerging resistance mechanisms for non-Hodgkin
lymphoma, target-negative relapse and checkpoint upregulation," said Dr. Anas
Younes, Chief, Lymphoma Service at Memorial Sloan Kettering Cancer Center.
Simultaneous Targeting of CD19 and CD22: Phase 1 Trial of AUTO3, a Bicistronic
Chimeric Antigen Receptor (CAR) T-cell Therapy, in Pediatric Patients with
Relapse/Refractory B-cell Acute Lymphoblastic Leukemia (r/r B-ALL): AMELIA
Trial (Abstract Number 279, oral presentation at 8:00AM on Sunday, December 2,
2018)
Dr. Amrolia reported on 10 patients with relapsed or refractory ALL who
received an AUTO3 infusion as a single dose or split dose dependent on their
tumor burden. Key inclusion criteria included age 1-24 years old with relapsed
or refractory B-lineage ALL at high risk in first relapse or in second or
greater relapse. Prior targeted therapies to CD19 and CD22 were not excluded.
The average age of the 10 evaluable patients was 8.5 years, the median number
of prior lines of therapy was 3. Product was successfully manufactured for all
patients. AUTO3 was generally well tolerated with no ? Grade 3 CRS, no ICU
admission, and no pressors or critical care support for CRS required. One case
of Grade 3 neurotoxicity was observed which was considered unlikely related to
AUTO3 and primarily attributed to prior intrathecal chemotherapy. Grade 3 or
higher cytopenias lasting at least 30 days were noted in 4 out of 10 patients.
Among the 10 evaluable patients at all dose levels, 8 out of 10 achieved MRD
negative CR and higher response rates were observed at doses ?3 x106/kg dose
levels with all patients achieving MRD-negative remission. In the higher dose
group, 4 out of 6 (67%) patients have an ongoing molecular CR and importantly,
no loss of CD19 or CD22 was noted among relapsed patients. Initial data
indicates response rates and persistence are dose dependant. Dose escalation is
ongoing.

Trial of AUTO3, the First Bicistronic Chimeric Antigen Receptor (CAR) Targeting
CD19 and CD22, Followed By Anti-PD1 Consolidation in Patients with Relapsed/
Refractory (r/r) Diffuse Large B Cell Lymphoma (DLBCL): Alexander Trial
(Abstract Number 1679, poster presentation from 6:15 PM - 8:15PM on Saturday,
December 1, 2018)
Dr. Kirit Ardeshna, principal investigator at University College London, UK,
reported preliminary clinical data on safety and efficacy from this open-label,
multi?center trial in patients with DLBCL treated with a single dose of AUTO3
followed by consolidation with anti-PD-1 antibody (pembrolizumab). Key
inclusion criteria included histologically confirmed DLBCL,
chemotherapy-refractory disease or relapse after at least two lines of therapy
or after ASCT, and no prior allogeneic stem cell transplant. There were 7
patients evaluable for safety with at least 28 day follow up post-treatment.
The median number of prior lines of therapy in these 7 evaluable patients was 3
(range was 2 to 4). All patients were treated at the starting dose of 50x106
transformed CAR T cells. Three patients received a consolidation with
pembrolizumab, and 4 patients did not receive treatment with pembrolizumab.
None of the treated patients developed CRS grade 3 or higher and one patient
had neurotoxicity grade 3, considered possibly related to AUTO3. No dose
limiting toxicities were observed and dose escalation continues. Six patients
were evaluable for response, two achieved a CR and two a PR; two patients did
not respond. The two CRs were ongoing at six and three months, respectively.

About AUTO3
AUTO3 is a programmed T cell therapy containing two independent chimeric
antigen receptors targeting CD19 and CD22 that have each been independently
optimized for single target activity. By simultaneously targeting two B cell
antigens, AUTO3 is designed to minimize relapse due to single antigen loss in
patients with B cell malignancies. AUTO3 is currently being tested in two
clinical trials, referred to as the AMELIA and ALEXANDER trials.
The AMELIA trial is a single-arm, open label, multi-center Phase 1/2 clinical
trial of AUTO3 in patients up to 24 years of age with high-risk relapsed or
refractory B-lineage. The trial also is enrolling patients who previously
received CD19 or CD22 targeting therapies including other CAR T cell therapy.
The primary objective for Phase 1 is to assess the safety and tolerability of
AUTO 3 administration as well as to identify the Phase 2 dose and schedule.
The purpose of this trial is to test the safety and efficacy, including the
complete remission rate or minimal residual disease (MRD) negative response, of
AUTO3. Autolus expects to enroll up to 54 patients in this trial.
The ALEXANDER trial is a single-arm, open label, multi-center Phase 1/2
clinical trial of AUTO3 in patients with relapsed or refractory diffuse large B
cell lymphoma (DLBCL). The primary objective for the Phase 1 portion is to
assess the safety and tolerability of AUTO3 administration as well as to
identify the recommended Phase 2 dose and maximum tolerated dose (MTD) of
AUTO3. The purpose of this trial is to test the safety and efficacy, including
the overall response rate as per Lugano criteria, of AUTO3 followed by limited
duration of consolidation with anti-PD1 antibody. Autolus expects to enroll
approximately 100 patients in this trial.
