Axovant Announces Partnership with Invitae to Increase Access to Genetic Testing and Accelerate Diagnoses of GM1 and GM2 Gangliosidosis

• Partnership to reduce barriers to genetic diagnosis through sponsored testing for lysosomal storage diseases

• Initiative supports identification of patients with GM1 and GM2 gangliosidosis who are currently misdiagnosed or undiagnosed

NEW YORK and BASEL, Switzerland, April 15, 2020 (GLOBE NEWSWIRE) -- Axovant Gene Therapies Ltd., a clinical-stage company developing innovative gene therapies for neurological diseases, today announced its collaboration with Invitae, a leading medical genetics company, in the Detect Lysosomal Storage Diseases ("Detect") program to facilitate faster diagnoses for children with lysosomal storage disorders ("LSDs"), including GM1 gangliosidosis and GM2 gangliosidosis, also known as Tay-Sachs/Sandhoff disease. Invitae offers genetic testing and counseling at no charge to patients suspected of having an LSD.

"Axovant is committed to developing novel gene therapies for those living with rapidly progressive neurodegenerative diseases. We are hopeful that our collaboration with Invitae will provide families with easier access to genetic testing and bring us one step closer to identifying patients who may benefit from potential therapies," said Parag Meswani, PharmD., Axovant's SVP of Commercial Strategy & Operations. "Our AXO-AAV-GM1 clinical program targeting GM1 gangliosidosis is currently enrolling at the National Institutes of Health, and we are seeking IND clearance for the AXO-AAV-GM2 clinical trial targeting Tay-Sachs and Sandhoff diseases. Early intervention is ideal with potentially disease-modifying genetic therapies, and our diagnostics partnership with Invitae should allow us to identify and enroll children at even earlier stages of disease progression."

LSDs are progressive, multi-system, inherited metabolic diseases associated with premature death, and genetic testing is a crucial first step to arriving at a diagnosis. LSDs are misdiagnosed or undiagnosed in the majority of patients. The Detect program includes a specific LSD testing panel of 53 genes designed to provide patients and families accurate information quickly to preserve valuable treatment time.

"Genetic testing can expedite an accurate diagnosis, facilitate earlier interventions, allow genetic counseling of family members, and support clinical research for LSDs such as GM1 and GM2 gangliosidosis," said Robert Nussbaum, M.D., chief medical officer of Invitae. "We're pleased Axovant has joined the Detect program to help offer no-charge, sponsored genetic testing for those patients suspected of having the disease."

Research has shown no-charge testing programs with large well-designed panels help increase utilization of genetic testing, which can shorten the time to diagnosis by as much as 2 years in some conditions. Accurate diagnoses enable clinicians to focus on providing disease-specific care sooner, helping reduce costs and improve outcomes.¹
