CHICAGO, Aug. 11, 2016 (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 second quarter ended June 30, 2016, recent corporate highlights and upcoming milestones, and provided an update on interim data from the ongoing Phase 1 trial of AVXS-101 in spinal muscular atrophy (SMA) Type 1.

Data as of July 1, 2016 showed AVXS-101 continued to demonstrate a favorable safety profile, with no new treatment-related safety or tolerability concerns identified. All patients in both Cohort 1 (low dose) and Cohort 2 (proposed therapeutic dose) remained without an “event,” defined as death or until a patient requires 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. Since July 1, one patient in the low-dose cohort has reached a ventilation endpoint, described in further detail below. As of July 1, the mean motor function scores in both dosing cohorts continued to increase, with 25% of patients in Cohort 2 having achieved motor function in a range considered to be normal.

“We continue to be encouraged with this interim data for AVXS-101 and are eager to collaborate with the FDA via the breakthrough designation process to determine next steps in the development pathway for SMA Type 1, and we have submitted a Type B meeting request with the agency to facilitate this discussion,” said Sean Nolan, President and Chief Executive Officer of AveXis. “We expect several key developments in the second half of the year including the presentation of developmental milestone data from our ongoing SMA Type 1 study, providing additional clarity on the development path for the Type 1 program and we expect to initiate our initial safety and dosing study in SMA Type 2 patients.”

Interim Phase 1 Data as of July 1, 2016

  • AVXS-101 appeared to have a favorable safety profile and to be generally well tolerated in patients studied, with no new treatment-related adverse events reported.
    • There have been a cumulative total of 107 adverse events (AEs) reported as of July 1, 2016, 31 of which were determined to be serious adverse events (SAEs). As previously reported, two of the 31 were deemed treatment-related and consisted of clinically asymptomatic liver enzyme elevations.
    • Of the cumulative total of 76 non-serious AEs reported as of July 1, 2016, three were the previously reported treatment-related elevations in liver enzymes experienced by two patients.
    • All of the elevated liver enzyme AEs and SAEs were clinically asymptomatic and resolved with prednisolone treatment. There were no elevations of GGT, alkaline phosphatase or bilirubin, and Hy’s Law was not met.
    • Other non-treatment-related AEs were expected and were associated with SMA.
  • Mean increases in motor function compared to baseline of 9.0 points in Cohort 1 and 23.3 points in Cohort 2 in CHOP-INTEND scores were observed. The Children’s Hospital of Philadelphia Infant Test of Neuromuscular Disorders (CHOP-INTEND) is a test developed to measure motor skills of patients with SMA Type 1.
    • Eleven out of 12 patients (92 percent) and 8 out of 12 patients (67 percent) in Cohort 2 had achieved CHOP-INTEND scores of at least 40 or 50 points, respectively.
    • Three out of 12 patients (25 percent) in Cohort 2 achieved a score of 60, which is in a range considered to be normal.

“These data demonstrate rapid, sustained and marked improvements in motor function as measured by CHOP-INTEND,” said Suku Nagendran, MD, Senior Vice President and Chief Medical Officer, AveXis. “Compared with the data presented as of April 1, 2016, the positive impact on average motor function scores increased from 8.7 to 9.0 points and from 19.2 to 23.3 points in Cohorts 1 and 2, respectively. It appears that both dose and baseline motor function are key factors in determining the degree of treatment response. Based on our data to date, early diagnosis and treatment appear to be critical for optimal outcomes in this population.”

Protocol-Specified Ventilation Event Occurring After July 1

  • The protocol defines the “permanent ventilation endpoint” as the use of at least 16 hours per day of respiratory assistance (includes non-invasive ventilatory support) continuously for greater than 2 weeks in the absence of an acute reversible illness, excluding perioperative ventilation. 
  • In the course of reviewing the data as of July 1, 2016, AveXis learned that one patient in Cohort 1, the low-dose group, had begun to increase use of bi-level positive airway pressure (BiPAP) in advance of surgery related to hypersalivation, a condition experienced by some SMA patients. This patient did not meet the definition of a permanent ventilation endpoint until after July 1, 2016. As a result, the independent Data Safety Monitoring Board (DSMB) determined that this development was not a “permanent ventilation endpoint” for the data as of July 1, 2016, but would be classified as an “event” for the next data period ending September 30, 2016. This event was determined by the DSMB to represent progression of disease and not an adverse event related to the use of AVXS-101.

Recent Highlights

  • Breakthrough Therapy Designation: On July 20, 2016, AveXis reported that the U.S. Food and Drug Administration (FDA) had granted Breakthrough Therapy Designation for AVXS-101 for the treatment of SMA Type 1 in pediatric patients based on preliminary clinical results from the ongoing trial of AVXS-101. In granting the designation, the FDA indicated that as a next step that AveXis should submit a Type B meeting request to facilitate a comprehensive discussion of the development pathway. AveXis has subsequently submitted the meeting request.
     
  • Pulmonary Support Data: On May 15, 2016, Richard Shell, MD, member of the Section of Pulmonary Medicine at Nationwide Children’s Hospital and an Associate Professor of Clinical Pediatrics at The Ohio State University College of Medicine, presented additional pulmonary support data at the International Conference of the American Thoracic Society in San Francisco.
    • The interim analysis presented at the meeting demonstrated gene therapy appeared to reduce the need for ventilation support and allowed patients to successfully recover from respiratory illnesses that are often lethal to SMA Type 1 patients. None of the patients in either dosing cohort required permanent ventilation as of April 1, 2016.
    • In addition, 8 of 10 (80 percent) patients on the proposed therapeutic dose of 2.0x1014 vg/kg who did not need biphasic/bi-level ventilation (BiPAP) support prior to gene therapy continued with no ventilation support. The two exceptions were children hospitalized in the first quarter of 2016 for severe respiratory illness and placed on BiPAP to aid recovery.

  • Presented Interim Data at ASGCT: On May 6, 2016, Jerry Mendell, MD, director of the Center for Gene Therapy at The Research Institute at Nationwide Children’s Hospital, presented interim data as of April 1, 2016 from the ongoing Phase 1 trial of AVXS-101 for the treatment of SMA Type 1 at the 19th Annual Meeting of the American Society of Gene & Cell Therapy in Washington, D.C.
     
  • Appointed Michael B. Johannesen to Executive Management Team: On July 5, 2016, Michael B. Johannesen was appointed Senior Vice President, General Counsel and Chief Compliance Officer. Mr. Johannesen brings to AveXis nearly 20 years of legal experience within the global pharmaceutical, medical device and healthcare products industries, and is responsible for all aspects of the company’s legal and compliance functions, as well as human resources.

Second Quarter 2016 Financial Results

  • Cash Position: As of June 30, 2016, AveXis had $131.4 million in cash and cash equivalents.

  • R&D Expenses: Research and development expenses were $10.4 million for the second quarter of 2016 (which included $1.3 million of stock-based compensation), compared to $7.7 million for the same period in 2015 (which included $5.8 million of stock-based compensation), an increase of $2.7 million. The increase in research and development expenses was primarily attributable to an increase in expenses necessary to support the advancement of the company’s manufacturing product development efforts, clinical and pre-clinical programs, primarily the ongoing trial of AVXS-101 in SMA Type 1, and increases in employee compensation. Partially offsetting the increase in R&D spending was lower stock-based compensation expense of $4.5 million.

  • G&A Expenses: General and administrative expenses were $5.4 million for the second quarter of 2016 (which included $2.6 million of stock-based compensation), compared to $2.3 million for the same period in 2015 (which included $0.8 million of stock-based compensation), an increase of $3.1 million. The increase in general and administrative expenses was primarily attributable to an increase in employee compensation, legal and professional fees and other infrastructure costs to support the company’s overall growth, and higher stock-based compensation expense.

  • Net Loss: Net loss was $15.7 million, or $0.68 per share, for the second quarter of 2016, compared to a net loss of $9.9 million, or $1.41 per share, for the second quarter of 2015.

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.

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.

About AVXS-101
AVXS-101 is a proprietary gene therapy candidate of a one-time treatment for SMA Type 1 and is the only clinical-stage gene therapy in development for SMA. AVXS-101 is designed to address the monogenetic 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.
