CHICAGO, May 11, 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 reported financial results for the first quarter ended March 31, 2017, recent corporate highlights and upcoming milestones.
“We are very pleased with our progress during the first quarter and recent weeks, including the recently reported encouraging results from the closeout of the Phase 1 trial of AVXS-101 in SMA Type 1,” said Sean Nolan, President and Chief Executive Officer of AveXis. “Our team is focused on executing our plan to bring AVXS-101 to patients suffering from SMA Type 1 as quickly and safely as possible.”
Results from the Phase 1 Trial of AVXS-101 in SMA Type 1: The Phase 1, open-label, dose-escalating study was designed to evaluate the safety and tolerability of AVXS-101 in patients with spinal muscular atrophy (SMA) Type 1. The key measures of efficacy were the time from birth to an “event,” which was defined as either death or at least 16 hours per day of required ventilation support for breathing for 14 consecutive days in the absence of acute reversible illness or perioperatively, and video confirmed achievement of ability to sit unassisted. Additionally, several exploratory objective measures were assessed, including a standard motor milestone development survey and Children’s Hospital of Philadelphia Infant Test of Neuromuscular Disorders (CHOP INTEND).
- Event-free Survival and Safety: Data as of January 20, 2017, showed no new events, and 15 of 15 (100%) patients event-free at 13.6 months. The expected event-free survival rate at 13.6 months based on the natural history of the disease is 25 percent. The median age at last follow-up was 20.2 months and 30.8 months for patients in the proposed therapeutic dose (Cohort 2) and low-dose (Cohort 1) cohorts respectively. AVXS-101 appeared to have a favorable safety profile and to be generally well tolerated, with no new treatment-related safety or tolerability concerns identified.
- Motor Milestone Achievement: As of January 20, 2017, 11 of 12 patients (92%) in Cohort 2 achieved head control, nine of 12 patients (75%) could roll a minimum of 180 degrees from back to both left and right, and 11 of 12 patients (92%) could sit with assistance.
• Nine of 12 patients (75%) in Cohort 2 could sit unassisted for at least five seconds, seven of 12 patients (58%) could sit unassisted for at least 10 seconds and five of 12 patients (42%) could sit unassisted for 30 seconds or more.
• Three patients in Cohort 2 have achieved additional sitting unassisted milestones since the January 20, 2017 evaluation date. Ten of 12 patients (83%) in Cohort 2 could sit unassisted for at least five seconds, nine of 12 (75%) patients could sit unassisted for at least 10 seconds and eight of 12 patients (67%) could sit unassisted for 30 seconds or more in the post-January 20 analysis.
• As of January 20, 2017, two patients in Cohort 2 could crawl, pull to a stand, and stand and walk independently.
- Nutritional and Respiratory Support: As of January 20, 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 continued without any BiPAP after treatment.
• Further, as of January 20, 2017, 11 of 12 (92%) patients in Cohort 2 were fed orally, and six of 12 (50%) patients were exclusively fed orally; and eight of 12 (67%) patients were able to speak.
Presented AVXS-101 research at the Annual Meeting of the American Academy of Neurology: Jerry Mendell, M.D., director of the Center for Gene Therapy at The Research Institute at Nationwide Children’s Hospital, presented results from the Phase 1 study of AVXS-101 in SMA Type 1 during a plenary session, including video evidence of children achieving motor milestones.
- Dr. Brian Kaspar, Senior Vice President and Chief Scientific Officer of AveXis, presented data from a dose-response study for the cerebrospinal fluid (CSF) delivery of AVXS-101 that offers insight into vector distribution and its correlation with transgene expression, providing guidance for future AAV9-based clinical trials in SMA, as well as other neurodegenerative disorders.
- Dr. Douglas Sproule, Vice President of Clinical Development and Medical Affairs of AveXis, presented data suggesting pre-existing antibodies to AAV9 are quite uncommon in the pediatric population and will not impact use of gene therapy for the vast majority of SMA Type 1 patients.
- Dr. Linda Lowes, Director of Clinical Therapies Research and a member of the Center for Gene Therapy at the Research Institute of Nationwide Children’s Hospital, presented research providing further evidence of the correlation between motor function and motor milestone achievement in patients with SMA Type 1, demonstrating that the degree of treatment outcome appears to be influenced by age at dosing and baseline motor function.
Completed Type B chemistry manufacturing and controls (CMC) meeting with the U.S. Food and Drug Administration (FDA): On May 1, 2017, AveXis participated in a Type B CMC meeting with the FDA. The purpose of the meeting was to present to the agency AveXis’ proposed process for producing the intended commercial scale GMP-derived gene therapy product, to gain alignment with the agency on the proposed assay qualification plan, and to gain alignment on the proposed protocol for demonstrating comparability of the intended commercial scale GMP-derived product with the material administered to patients in the Phase 1 trial of AVXS-101 in SMA Type 1.
The company expects to provide an update on its further plans and development timelines following receipt of the minutes of the CMC Type B meeting, currently anticipated in early June 2017.
Joao Siffert Appointed to Board of Directors: On April 19, 2017, AveXis announced the appointment of Joao Siffert to its Board of Directors, effective upon the completion of the annual meeting of stockholders. Dr. Siffert brings important knowledge to the Board based on his experience in central nervous system drug development and regulatory expertise in both the U.S. and Europe, as well as his experience working with global health care companies.
First Quarter 2017 Financial Results
- Cash Position: As of March 31, 2017, AveXis had $204.5 million in cash and cash equivalents.
- R&D Expenses: Research and development expenses were $20.3 million for the first quarter of 2017 (which included $2.3 million of non-cash stock-based compensation expense), compared to $16.1 million for the same period in 2016 (which included $11.5 million of non-cash stock-based compensation expense). Excluding the impact attributable to non-cash compensation expense, research and development expenses increased $13.4 million. The increase was primarily attributable to product manufacturing expenses and associated accelerated spending related to the company’s Libertyville, Illinois product manufacturing facility, associated increased headcount as well as expenses related to the conclusion of the Phase 1 clinical trial of AVXS-101 in SMA Type 1.
- G&A Expenses: General and administrative expenses were $9.6 million for the first quarter of 2017 (which included $2.8 million of non-cash stock-based compensation expense), compared to $4.8 million for the same period in 2016 (which included $2.1 million of stock-based compensation expense), an increase of $4.8 million. Excluding the impact attributable to non-cash compensation expense, general and administrative expenses increased $4.1 million. The increase was primarily attributable to increases in salaries and personnel-related costs, legal, professional and consulting fees and other administrative costs driven by increased headcount across all general and administrative functions to support the company’s overall growth.
- Net Loss: Net loss was $29.7 million, or $1.07 per share, for the first quarter of 2017, compared to a net loss of $20.8 million, or $1.24 per share, for the first quarter of 2016.

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.
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 1 is the leading genetic cause of infant mortality.
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 SMN 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.

Non-GAAP Financial Measure
In addition to disclosing financial results that are determined in accordance with GAAP, in order to understand and evaluate our operating performance, and provide a more complete understanding of factors and trends affecting our business, we also measure the increase in research and development expenses and general and administrative expenses excluding non-cash stock-based compensation expense. We believe that excluding this expense better reflects the increase in research and development and general and administrative expenses during the period, as compared to the prior period. This non-GAAP financial metric should be considered supplemental to and not a substitute for financial information prepared in accordance with GAAP. Because non-GAAP financial metrics exclude the effect of items that will increase or decrease the company’s reported results of operations, we strongly encourage investors to review our consolidated financial statements and periodic reports in their entirety.
