Autolus Therapeutics (AUTL) Announces Publication Describing its Controllable CAR T Cell System
Autolus Therapeutics plc (Nasdaq: AUTL), a clinical-stage biopharmaceutical company developing next-generation programmed T cell therapies, today announced the publication of an article in Nature Scientific Reports describing a controllable CAR T cell system (TetCAR), designed to reversibly dampen the activity of the programmed T cells by the administration of the licensed and widely available antibiotics tetracycline and minocycline.1
Management of toxicities is a critical step in the successful application of programmed cell therapies. TetCAR is one of a number of approaches developed at Autolus that use a pharmacological agent to selectively control or eliminate cell therapies in the event a patient experiences severe adverse side effects from the treatment.
Safety switches, like Autolus’ Rituxumab and Rapamycin controlled systems (RQR82 and RapaCasp93), are designed to selectively eliminate a programmed cell therapy following administration of a pharmacological agent, whilst controllable systems, like the TetCAR approach described in this publication, are designed to allow the activity of a CAR T cell therapy to be dialed down following administration of a pharmacological agent to a patient and then subsequently restored on clearance of the pharmacological agent from the patient.
“While many such systems have been described, most require use of experimental small molecules for control. Our TetCAR, RQR8 and Rapacasp9 approaches, all use licensed and widely available drugs, offering practical application of these systems in the clinic,” said Dr. Martin Pule, chief scientific officer of Autolus. “We are excited to highlight this new publication which underscores the strong technology and IP base that we are using to develop the next generation of programmed cell therapies, both in-house and in partnership.”
