Ongoing Clinical Trials
**** Copied verbatim from AveXis press release (Link in HELPFUL LINKS page) ****
- Pivotal Trial of AVXS-101 in SMA Type 1 (STR1VE): The ongoing, open-label, single-arm, single-dose, multi-center trial is designed to evaluate the efficacy and safety of a one-time IV infusion of AVXS-101 in patients with SMA Type 1. The trial is expected to enroll a minimum of 15 patients with SMA Type 1 who are less than six months of age at the time of gene therapy, and who have one or two copies of the SMN2 backup gene as determined by genetic testing and bi-allelic SMN1gene deletion or point mutations. Three patients have been dosed to date. The trial identifier is NCT03306277 Go to https://www.clinicaltrials.gov/ct2/home and enter the trial identifier number in the search box labeled Other terms.

Estimated Enrollment: 44 participants
Actual Study Start Date: September 29, 2017
Estimated Primary Completion Date: March 31, 2020
Estimated Study Completion Date: March 31, 2020
Ages Eligible for Study: up to 180 Days (Child)
- Phase 1 Trial of AVXS-101 in SMA Type 2 (STRONG): The on-going, open-label, dose-comparison, multi-center Phase 1 trial is designed to evaluate the safety, optimal dosing, and proof of concept for efficacy of AVXS-101 in two distinct age groups of patients with SMA Type 2, utilizing a one-time intrathecal (IT) route of administration. The trial is expected to enroll 27 infants and children who are symptomatic with a genetic diagnosis consistent with SMA, including the bi-allelic deletion of SMN1 and three copies of SMN2 without the SMN2 genetic modifier, who are able to sit but have no historical or current ability to stand or walk. One patient has been dosed to date. The trial identifier is NCT03381729 Go to https://www.clinicaltrials.gov/ct2/home and enter the trial identifier number in the search box labeled Other terms.

Estimated Enrollment: 27 participants
Actual Study Start Date: December 14, 2017
Estimated Primary Completion Date: August 30, 2019
Estimated Study Completion Date: August 30, 2019
Ages Eligible for Study: up to 60 Months (Child)
Planned Trials In SMA ( I will update with trial identifiers when each trial starts )
- 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.
- 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 those affected will never walk without support and most will never stand without support. SMA Type 2 results in mortality in more than 30 percent of patients by the age of 25.
- 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 is also designed to target motor neurons, providing rapid onset of effect and crossing the blood brain barrier to allow 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 trial for SMA Type 2. The company also intends to expand its development 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.
