Autolus Therapeutics Announces New Data Showcasing
Clinical Progress of AUTO3 in B Cell Malignancies
Preliminary data on AUTO3 in DLBCL demonstrate safety and feasibilty of CD19 and CD22 dual targeting CAR T
90% complete response and 100% overall survival at 12 months in CAR T naive
pediatric ALL patients dosed with AUTO3
Investor call to be held at / to review data
-- (Nasdaq: AUTL) announced today new data highlighting progress on AUTO3, the first-in-human bicistronic CD19 and CD22 CAR, in patients with relapsed/refractory diffuse large B-cell lymphoma (DLBCL) and pediatric acute lymphoblastic leukemia (ALL). The data were presented at the 61 American Society of Hematology (ASH) Annual Meeting and Exposition in Orlando, FL.LONDON, UK,
“DLBCL is an aggressive and rapidly progressing cancer, and early response is critical to ensuring positive outcomes for these patients. The data from the AMELIA trial of AUTO3 in pediatric ALL has informed us on the encouraging role of dual antigen targeting in reducing target-negative relapses and delivering high levels of complete molecular remission with well-tolerated safety,” said Dr. , chairman and chief executive officer of Autolus. “We look forward to advancing AUTO3 to a decision point in relapsed/refractory DLBCL by the mid-point of next year.”
Title: Phase 1/2 study of AUTO3, the first bicistronic chimeric antigen receptor (CAR) targeting CD19 and CD22 followed by an anti-PD1 in patients with relapsed/refractory (r/r) Diffuse Large B Cell Lymphoma (DLBCL): Results of cohort 1 and 2 of the ALEXANDER study (Abstract # 246)
Dr. , consultant hematologist, , , gave an oral presentation with updated data from the ALEXANDER Phase I/2 study of AUTO3, the first bicistronic CAR T targeting CD19 and CD22 followed by an anti-PD1, in Diffuse Large B Cell Lymphoma (DLBCL). The trial is divided into a phase 1 safety cohort and a phase 2 efficacy cohort, and is designed to assess safety (incidence of ? Grade 3 toxicity occurring within 75 days of AUTO3 infusion) and other primary and secondary endpoints including overall response and other safety, efficacy and product generation measures.
In the dose escalation phase, 16 patients were treated, with 4 patients dosed at 50 x 10 cells without pembrolizumab; 11 patients were dosed at escalating doses of AUTO3 with pembrolizumab administered at day 14 as follows: 3 at 50 x 10 cells, 4 at 150 x 10 cells, and 4 at 450 x 10 of AUTO3; and 1 patient was dosed with 450 x 10 cells with pembrolizumab administered 1 day before AUTO3 infusion. Fourteen patients were evaluable at one month.66666
AUTO3 was well-tolerated, with no patients experiencing ? Grade 3 cytokine release syndrome (CRS) with primary infusion and 1 of 14 experiencing Grade 3 neurotoxicity that resolved swiftly with steroids. There were no pembrolizumab immune-related toxicities and the majority of grade 3 or higher adverse events were hematological. Low levels of serum cytokines are consistent with the observed low levels of CRS and neurotoxicity.
Across all tested doses 5 patients achieved a complete response, with 4 of 5 complete responses ongoing, the longest at 18 months. All CRs were achieved without need for steroid or tocilizumab-based management of the patients or ICU level care.
“The phase 1 preliminary data on AUTO3, the novel and first in human bicistronic CD19 and CD22 CAR in relapsed/refractory DLBCL, show that the dual targeting approach appears safe, with 0% severe CRS (? grade 3). The duration of complete response is impressive as well and provides hope that AUTO3 may reduce the high rates of relapse seen with CD19 CAR Ts,” said Dr. Anas Younes, Chief, Lymphoma Service at Memorial Sloan Kettering Cancer Center.
AUTO3 – (Poster) -Phase 1/2 AMELIA clinical trial of AUTO3 in patients with relapsed/refractory pediatric acute lymphoblastic leukemia (pALL) (Abstract # 2620)
Professor , 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), presented data from the AMELIA trial, a Phase 1/2, open-label, multi?center study to characterize the safety and clinical activity of AUTO3 in pediatric and young adult patients with relapsed/refractory ALL. The study recruited a total of 18 patients to the active dose (? 3 x 10 /kg) cohorts, and product was manufactured successfully for 14 of the 15 patients (93%) who underwent leukapheresis. Eleven patients were treated with AUTO3, manufactured using a semi-automated closed manufacturing process. Ten of 11 patients were CAR T cell-naive, while 1 had previously received CAR T cell therapy.
AUTO3 was well-tolerated overall, with no patients experiencing ? Grade 3 CRS and no patients experiencing ? Grade 2 neurotoxicity, in doses ?3x10 /kg CAR-T cells. No AUTO3-related deaths were reported.6
Among the 10 CAR T-naïve patients, at a median follow-up time of 9.7 months (range 1.8- 18), 9 of 10 patients (90%) achieved a complete response, and 8 of 10 (80%) achieved complete molecular remission by PCR. Estimated overall survival at 12 months was 100%. There are 2 ongoing patients in complete molecular remission at 12 and 15 months post-AUTO3 infusion, respectively. The most common cause of relapse was due to loss of CAR T-cell persistence. The median persistence of CAR-T cells in blood was 170 days.

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 pediatric ALL in the AMELIA clinical trial and in diffuse large B cell lymphoma in the ALEXANDER clinical trial.
