Initial Results from Autolus Therapeutics’ ALLCAR19 Phase 1/2 Trial in Adult Acute Lymphoblastic Leukemia Presented at the AACR Annual Meeting
Initial results from the trial show 88% molecular complete response at one month with
well-tolerated safety profile
Management to Hold Conference Call on April 2, 2019 at 8:00am ET / 1:00pm BST
LONDON, UK, April 1, 2019 -- Autolus Therapeutics plc (Nasdaq: AUTL), a clinical-stage biopharmaceutical company developing next-generation programmed T cell therapies for the treatment of cancer, announced that Claire Roddie MB, PhD, FRCPath, honorary senior lecturer, Cancer Institute, University College London (UCL), presented today initial data from the ongoing Phase 1/2 ALLCAR19 trial of AUTO1 in adult acute lymphoblastic B cell leukemia (ALL) as a late-breaking poster presentation at the American Association for Cancer Research (AACR) Annual Meeting 2019 in Atlanta, Georgia.
Relapsed / refractory B-cell acute lymphoblastic leukemia (r/r B-ALL) in adults is an area of significant unmet clinical need. Notably, no CD19 CAR T cell therapeutic has been approved for adults with r/r B-ALL. The key challenges identified in clinical studies testing standard CD19 CAR T-cells therapies in this setting are considerable toxicity associated with severe cytokine release syndrome (CRS) and high-grade neurological toxicity.
AUTO1 uses a novel CD19 binder that allows the CAR T cells to disengage rapidly after target cell encounter and kill. Data from the ongoing Phase 1/2 CARPALL trial of AUTO1 in pediatric ALL presented at the EHA CAR T Meeting in February 2019 has shown that AUTO1 has a well-tolerated safety profile without inducing high grade CRS in pediatric patients.
As of the data cutoff date of March 18, 2019 in the ongoing Phase 1/2 ALLCAR19 trial of AUTO1 in adult ALL patients, 13 patients were leukapheresed, and products for 12 patients were manufactured, including 7 with Autolus’ semi-automated, fully enclosed manufacturing process. Two patients are pending infusion. Among the 10 infused patients to date, the median age is 41 and 70% were male, with median lines of treatment of 4 (the range is 2-7). Five of the ten treated patients had ? 50% BM blasts and were considered to be high-risk for severe CRS. Patients received a split dose based on disease burden for a total dose of up to 410 million cells.
Using the Lee criteria, there were no patients with severe CRS (? Grade 3), and 2 of 10 patients (20%) with Grade 2 CRS. Tocilizumab was used in 2 of 10 patients (20%). None of the patients were admitted to intensive care due to CRS. One patient developed delayed G3 neurotoxicity following high levels of CAR T expansion, which was quickly reversed with steroids. Four patients died on study, two due to progression of leukemia and two due to sepsis, a common complication of advanced ALL.
Nine patients were evaluable for response at 1 month and 8 (88%) had a molecular complete response. One patient died of sepsis before the one-month evaluation point. At a median follow up of 5 months (range 0.62-10.6 months), 6/10 patients are alive and continue to be in molecular remission. There continues to be evidence of ongoing B cell aplasia and CAR T persistence.
“AUTO1 delivered promising early remission rates, CAR T cell expansion and persistence in this adult ALL trial cohort,” said Dr. Roddie. “Despite enrolling patients with high tumor burden, the safety profile in the trial appears to compare very favorably to other CD19 CARs and is consistent with the safety profile of AUTO1 observed in pediatric patients in the CARPALL trial.”
“These data from the ALLCAR19 study of AUTO1 in relapsed refractory ALL, while early, are extremely encouraging, with a high response rate we now associate with CAR T cell therapies, but with a potentially improved safety profile. If AUTO1 continues to be associated with a lower incidence of adverse events with additional patients treated, this could represent an important advance for more vulnerable adult patients, as side effects of these therapies, including serious cytokine release syndrome and neurotoxicity, limit our ability to treat these individuals.” said Krishna Komanduri, M.D., Kalish Family Chair in Stem Cell Transplantation and Director, Adult Stem Cell Transplant Program at the Sylvester Comprehensive Cancer Center at the University of Miami Miller School of Medicine.
“The strong persistence of the CAR T cells over time, coupled with the low frequency of severe CRS events seen in these patients, represent encouraging initial data for AUTO1 in relapsed/refractory adult ALL,” said Dr. Christian Itin, chairman and chief executive officer of Autolus Therapeutics. “We expect AUTO1 in adult ALL to move into a registration trial towards the end of this year.”

AUTO1 is a CD19 CAR T cell investigational therapy designed to overcome the limitations in safety - while maintaining similar levels of efficacy - 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, Autolus believes AUTO1 may reduce toxicity and be less prone to T cell exhaustion, which could enhance persistence and improve the T cells’ abilities to engage in serial killing of target cancer cells. In 2018, Autolus signed a license agreement under which Autolus acquired global rights from UCL Business plc (UCLB), the technology-transfer company of UCL, to develop and commercialize AUTO1 for the treatment of B cell malignancies. AUTO1 is currently being evaluated in two Phase 1/2 trials, one in pediatric ALL and one in adult ALL.
About Adult Acute Lymphoblastic Leukemia
According to the American Cancer Society, acute lymphoblastic leukemia (ALL) is predicted to affect approximately 5,960 adults in the United States in 2018. Combination chemotherapy enables 90% of adult patients to experience CR (complete response). Despite this, the prognosis of adult ALL is still poor and has not changed significantly during the last two to three decades, with long-term remission rates limited to 30–40%. Approximately 50% of all adult ALL patients will relapse.
