AveXis – First patient dosed in Phase 1 trial of AVXS-101 in SMA Type

CHICAGO, Jan. 16, 2018 (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 provided an overview of the expanded clinical development program for the company’s initial gene therapy candidate, AVXS-101, for the treatment of spinal muscular atrophy (SMA). In addition to the ongoing pivotal trial in SMA Type 1 (STR1VE) and the ongoing Phase 1 trial in SMA Type 2 (STRONG), the company plans to initiate three studies to further evaluate AVXS-101, including in new SMA patient populations. Additionally, the company announced the first patient has been dosed in the Phase 1 trial of AVXS-101 in SMA Type 2.

Planned Trials in SMA

Pivotal Trial of AVXS-101 in SMA Type 1 in Europe (STR1VE EU): The planned trial is expected to reflect a single-arm design, using natural history of the disease as a comparator, and is expected to enroll approximately 30 patients with SMA Type 1 who are less than six months of age at the time of gene therapy. The trial is designed to evaluate safety and efficacy of a one-time IV dose of AVXS-101, including 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. AveXis incorporated scientific advice from the European Medicines Agency into the protocol design, and expects to initiate the trial in the first half of 2018.

Pre-Symptomatic SMA Types 1, 2, 3 (SPRINT): The planned multi-national trial is expected to enroll approximately 44 patients with two, three and four copies of SMN2 who are less than six weeks of age and pre-symptomatic at the time of gene therapy. The trial is designed to evaluate appropriate clinical endpoints, including developmental milestones, survival, bulbar function and safety, of a one-time IV infusion of AVXS-101. AveXis expects to initiate the trial in the first half of 2018, and will provide more design details at the time of initiation.

Pediatric “All Comers” with SMA Types 1, 2, 3 (REACH): The planned multi-national trial is expected to enroll approximately 50 patients between approximately six months and 18 years of age who do not qualify for other AVXS-101 trials at the time of gene therapy. The trial is designed to evaluate a one-time IT dose of AVXS-101. AveXis expects to initiate the trial in late Q4 2018 or early 2019, and will provide more trial design details at the time of initiation.
