Autolus Therapeutics to Present New Data on AUTO1 in r/r Indolent B Cell Lymphomas at the European Hematology Association Virtual Congress

AUTO1 achieves 100% complete remission rate in cohort of r/r Indolent Non- Hodgkin Lymphoma patients

No high-grade cytokine release syndrome or neurotoxicity observed

LONDON, May 12, 2021 (GLOBE NEWSWIRE) -- Autolus Therapeutics plc (Nasdaq: AUTL), a clinical-stage biopharmaceutical company developing next-generation programmed T cell therapies, today announced an abstract presentation related to AUTO1 in relapsed / refractory (r/r) indolent B cell lymphomas (IBCL) at the European Hematology Association () Virtual Congress to be held June 9-17, 2021.

Title: Early safety and efficacy findings of AUTO1 (CAT19), a fast-off rate CD19 CAR, in Relapsed/Refractory Indolent B Cell Lymphomas

Presenter: Clare Roddie, MD, PhD, FRCPath, Consultant Haematologist and Honorary Senior Lecturer, Cancer Institute, University College London (UCL)

Date and Time: All e-poster presentations will be made available on the on-demand Virtual Congress platform as of Friday, June 11 at 9.00 AM CEST.

As of the data cut-off date of February 18, 2021, 10 r/r IBCL patients had received AUTO1 and nine patients were evaluable. AUTO1 demonstrated a tolerable safety profile in adult patients with r/r low grade B-cell lymphoma despite high disease burden. Early data shows 100% complete remission rates and excellent CAR engraftment and expansion. Grade 1 CRS was reported in 4 patients and Grade 2 CRS in 1 patient. No Immune effector cell-associated neurotoxicity syndrome (ICANS) was observed on study. At a median of 3.1 months (range 1-5.6m), 8/9 patients are in ongoing remission. One patient died in complete remission at month 5.6 of COVID-19.

Autolus has a pipeline of product candidates in development for the treatment of hematological malignancies and solid tumors. For more information, please visit .

About AUTO1 

AUTO1 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, AUTO1 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 our academic partner, UCL, AUTO1 is currently being evaluated in a Phase 1 clinical trial in adult ALL and B-NHL. The company has also progressed AUTO1 to the FELIX study, a potential pivotal study.

Forward-Looking Statements
