Company provides update following receipt of Scientific Advice response from the EMA
CHICAGO, Feb. 06, 2017 (GLOBE NEWSWIRE) -- AveXis, Inc. (NASDAQ:AVXS), a clinical-stage gene therapy company developing treatments for patients suffering from rare and life-threatening neurological genetic diseases, today announced that the planned pivotal study of AVXS-101 in spinal muscular atrophy (SMA) Type 1 in the European Union (EU) will reflect a single-arm design, using natural history of the disease as a comparator, and will enroll approximately 30 patients. This update is based on the receipt of the Scientific Advice response from the Scientific Advice Working Party within the Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency (EMA).
In addition to evaluating safety the planned pivotal trial is expected to evaluate achievement of motor milestones, specifically patients’ ability to sit unassisted, as well as an efficacy measure defined by the time from birth to an “event,” defined as death or requiring at least 16 hours per day of ventilation support for breathing for greater than two weeks in the absence of an acute reversible illness, or perioperatively.
“The scientific advice process has been quite productive, with the EMA providing constructive guidance on a pivotal study design most appropriate for EU product registration,” said James L’Italien, Ph.D., Senior Vice President, Chief Regulatory and Quality Officer of AveXis. “We will utilize the enhanced communication pathways afforded to us via the PRIority MEdicines program and work in collaboration with the EMA to generate the high-quality data needed to support the most rapid submission that meets the requirements for marketing authorization in the EU.”
The CHMP additionally recommended AveXis discuss the potential for Conditional Marketing Authorization in a future meeting with EMA.
More specific clinical trial details will be made available at the time the study is initiated, which is expected in the second half of 2017.
The company expects to initiate a separate pivotal clinical trial of AVXS-101 in SMA Type 1 in the United States in the first half of 2017.
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. SMA 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.
AVXS-101 is a proprietary gene therapy candidate of a one-time treatment for SMA Type 1 and is designed to address the monogenic root cause of SMA and prevent further muscle degeneration by addressing the defective and/or loss of the primary SMN1 gene. AVXS-101 also targets motor neurons providing rapid onset of effect, and crosses the blood brain barrier allowing an IV dosing route and effective targeting of both central and systemic features.
