– Bristol Myers Squibb to receive access to Autolus’ RQR8 safety switch for use in cell therapy programs –

– Autolus to receive an upfront payment, with potential for near term option exercise fees and development milestone payments plus royalties –

LONDON, UK I October 04, 2022 I Autolus Therapeutics plc (Nasdaq: AUTL), a clinical-stage biopharmaceutical company developing next-generation programmed T cell therapies, today announces that it has entered into an agreement with Bristol Myers Squibb (NYSE: BMY). The agreement grants Bristol Myers Squibb access to incorporate Autolus’ proprietary RQR8 safety switch into an initial set of selected cell therapy programs on a target-by-target basis for the treatment of cancer, with an option for Bristol Myers Squibb to incorporate the RQR8 safety switch in additional cell therapy programs beyond the initial set of selected programs.

Managing toxicities is a critical step in the successful application of programed cell therapies. Safety switches are designed to allow the use of pharmacological agents to selectively eliminate a cell therapy in the event a patient experiences severe adverse side effects from the treatment. Autolus’ proprietary RQR8 switch works by administration with the widely available and approved pharmaceutical antibody, rituximab. Once administered, rituximab binds to the engineered CD20 epitopes on the surface of the cell therapy and triggers selective cell death1.

Safety switches form part of Autolus’ industry-leading suite of cell programing modules that are designed to provide precise targeting, controlled, enhanced and sustained CAR T activity in a hostile tumor microenvironment.

Under the terms of the agreement, Autolus will receive an upfront payment for access to the RQR8 safety switch for the initial set of cell therapy programs with the potential for near term option exercise fees and development milestone payments. In addition, Autolus would be entitled to receive royalties on net sales of all Bristol Myers Squibb cell therapy products that incorporate the RQR8 safety switch.

“Safety switches are critical to the future of our field of advanced cell therapies. They allow us to develop approaches that are designed to significantly improve patient outcomes, whilst at the same time incorporating the potential to reduce the risk of severe adverse side effects from the treatment,” said Dr. Martin Pule, CSO of Autolus. “Next-generation, modular CAR T innovation is at the core of Autolus and RQR8 is incorporated in several of our product candidates. We look forward to partnering with Bristol Myers Squibb to bring the potential utility of our proprietary safety switch to their programs. I would like to take this opportunity to thank our excellent research team at Autolus for their continued hard work.”
