Autolus Therapeutics announces publication of new AUTO6 Phase 1 data in childhood neuroblastoma in Science Translational Medicine
- Findings from the Phase 1 study provide evidence that AUTO6 induces clinical activity in this solid tumor setting without inducing on-target off-tumor toxicity
- AUTO6NG builds on this approach utilizing the same GD2 CAR alongside additional programming modules to enhance the efficacy and persistence, expected to enter the clinic in 2021
LONDON, Nov. 30, 2020 (GLOBE NEWSWIRE) -- Autolus Therapeutics plc (Nasdaq: AUTL), a clinical-stage biopharmaceutical company developing next-generation programmed T cell therapies, announces publication of AUTO6 (1RG-CAR T) Phase 1 data in . AUTO6 is a second generation GD2-targeting CAR T candidate, developed in collaboration with UCL, and the trial was sponsored and run by Cancer Research UK’s Centre for Drug Development.
These new results highlight that AUTO6 can induce rapid regression of bulky disease in a solid tumor setting without inducing on-target off-tumor toxicity, despite dose dependent CAR T expansion. CAR T cell expansion was observed in all six patients treated at the higher cell dose cohorts in this Phase 1 study. Three of these six patients demonstrated evidence of transient CAR T cell activity, including cytokine release syndrome, and regression of soft tissue and bone marrow disease activity. The GD2 binder used in AUTO6 has been designed to minimize on-target off-tumor neurotoxicity associated with GD2 expression at low levels in pain fibers and the brain. Despite the presence of clear CAR T cell activity, no neurotoxicity was observed. The publication also suggests that, whilst AUTO6 is a valid and safe strategy for targeting neuroblastoma, further modifications are required to promote CAR T cell persistence and induce deeper and more durable responses for these patients.
“We are encouraged by the anti-tumor activity in neuroblastoma, a disease where there are limited therapeutic options for children with relapsed or refractory disease,” said Dr Karin Straathof, Consultant Paediatric Oncologist and research group leader at UCL Great Ormond Street Institute for Child Health. “This is of particular importance as this activity was observed in the absence of neurotoxicity which occurs with antibody-based approaches that target GD2.”
Nigel Blackburn, director of drug development at Cancer Research UK, said, “Children who have hard to treat, or relapsed cancer have limited treatment options open to them, and early results of AUTO6 are encouraging. We look forward to seeing the next steps in the development of AUTO6NG, and if the treatment has durable effects in neuroblastoma.”
“This is amongst the clearest data which demonstrate that CAR T cells can be highly active against advanced solid cancers,” said Dr Martin Pule, CSO and founder of Autolus and director of the UCL CAR T programme. “It is encouraging that highly active CAR T cells do not cause on-target off-tumor neurotoxicity and the findings represent an important step in our ongoing efforts to develop CAR T cell therapies for solid cancers.”
These data support Autolus’ continued development of AUTO6NG, which builds on this approach utilizing the same GD2 CAR alongside additional programming modules designed to enhance efficacy and persistence. Earlier this year at the American Association for Cancer Research (AACR) meeting, Autolus announced a preclinical data update demonstrating the validity of GD2 as a CAR T target in small cell lung cancer (SCLC) and the ability of Autolus’ efficacy-enhancing modules to drive in vivo efficacy in an SCLC mouse model. The data also suggested AUTO6NG can overcome the immune suppressive mechanisms in the tumor microenvironment. Autolus plans to test AUTO6NG in a Phase 1 study in 2021.

About Neuroblastoma
Neuroblastoma is the most common solid tumor in children that occurs outside of the brain and makes up 8% of the total number of children’s cancers. The site of origin is either in one of the two adrenal glands situated in the abdomen or in nerve tissue that runs alongside the spinal cord, in the neck, chest, abdomen or pelvis. The adrenal glands normally release hormones to maintain blood pressure and enable the body to respond to stress. In up to half of patients diagnosed with neuroblastoma, the tumor has spread to tissues beyond the original site such as the bone marrow, bone, lymph nodes, liver, and skin. As with most cancers, the cause of neuroblastoma is not known. When the lesion is localised, it is generally curable. However, long-term survival for children with advanced disease older than 18 months of age is poor despite aggressive multimodal therapy.
About AUTO6NG
AUTO6NG is a next generation programmed T cell product candidate in pre-clinical development. AUTO6NG builds on preliminary proof of concept data from AUTO6, a CAR targeting GD2-expression cancer cell currently in clinical development for the treatment of neuroblastoma. AUTO6NG incorporates additional cell programming modules to overcome immune suppressive defence mechanisms in the tumor microenvironment, in addition to endowing the CAR T cells with extended persistence capacity. AUTO6NG is currently in preclinical development for the potential treatment of both neuroblastoma and other GD2-expressing solid tumors, including osteosarcoma, soft tissue sarcoma, small cell lung cancer, and melanoma.
