Nutritional and Respiratory Support


·                  According to natural history of the disease, nearly all Type 1 patients require nutritional and respiratory support by 12 months of age, and are not able to swallow or speak effectively.


·                  As of August 7, 2017, patients who were free of respiratory or feeding support on January 20, 2017, continued without the need for supportive care.


·                  As of August 7, 2017, six of seven (86%) patients in Cohort 2 that did not require feeding support before treatment continued without feeding support after treatment; seven of 10 (70%) patients that did not require bi-level positive airway pressure (BiPAP) support before treatment did not require BiPAP support at last assessment.


·                  As of August 7, 2017, eleven of 12 (92%) patients in Cohort 2 were fed orally, and six of 12 (50%) patients were exclusively fed orally.


·                  Further, as of August 7, 2017, eleven of 12 (92%) patients were able to speak; three more patients than previously reported on April 25, 2017 at the American Academy of Neurology.


“AveXis and my team at Nationwide Children’s Hospital have worked tirelessly to alter the inevitable course of SMA Type 1,” Jerry Mendell, MD, principal investigator in the Center for Gene Therapy at Nationwide Children’s Hospital. “We are proud to see these data published in New England Journal of Medicine, representing the culmination of decades of dedication and commitment to making a better life possible for the children diagnosed with this unforgiving condition.”


AVXS-101 is currently being evaluated in a pivotal trial for the treatment of SMA Type 1.


About SMA


SMA is a severe neuromuscular disease characterized by the loss of motor neurons leading to progressive muscle weakness and paralysis. SMA is caused by a genetic defect in the SMN1 gene that codes SMN, a protein necessary for survival of motor neurons. The incidence of SMA is approximately one in 10,000 live births and is the leading genetic cause of infant mortality.


The most severe form of SMA is Type 1, a lethal genetic disorder characterized by motor neuron loss and associated muscle deterioration, which results in mortality or the need for permanent ventilation support before the age of two for greater than 90 percent of patients. SMA Type 2 typically presents between six and 18 months of age and affected patients can sit unassisted but never walk or stand without support.


About AVXS-101


AVXS-101 is a proprietary gene therapy candidate of a one-time treatment for SMA Types 1 and 2, designed to address the monogenic root cause of SMA and prevent further muscle degeneration by addressing the defective and/or loss of the primary SMN gene. AVXS-101 also targets motor neurons, providing rapid onset of effect and crossing the blood brain barrier to allow effective targeting of both central and systemic features.


About AveXis, Inc.


AveXis is a clinical-stage gene therapy company developing treatments for patients suffering from rare and life-threatening neurological genetic diseases. The company’s initial proprietary gene therapy candidate, AVXS-101, is in the pivotal phase of study for the treatment of SMA Type 1, and a Phase 1/2a study for SMA Type 2. The company also intends to expand the study of gene therapy into two additional rare neurological monogenic disorders: Rett syndrome (RTT) and a genetic form of amyotrophic lateral sclerosis (ALS) caused by mutations in the superoxide dismutase 1 (SOD1) gene.
