In addition, the secondary endpoints did not meet statistical significance. No new safety findings were identified on initial review of data other than those already noted in the ACTIMMUNE prescribing information for approved indications. The Company, in conjunction with the independent Data Safety Monitoring Board, the principal investigator and the Friedreich's Ataxia Research Alliance (FARA) Collaborative Clinical Research Network (CCRN) in FA, has determined that, based on the trial results, the FA development program will be discontinued, including the 26-week extension study and the long-term safety study.
Patients participating in the ongoing extension studies should contact their study site coordinator for further information and next steps.
The Company will continue to work with FARA and the principal investigator to further analyze the data to help inform future research efforts as well as future data presentation or publication.
"A well-designed, rigorous study like STEADFAST would not have been possible without the extraordinary drive of the FA community, particularly the people who enrolled in the study, the clinical trial investigators and the Friedreich's
"FARA's mission is to drive research to develop therapies that will treat and cure Friedreich's ataxia and we remain passionately committed to that mission so that one day soon patients and caregivers impacted by this devastating disease will have effective treatment options," said Ronald J. Bartek, co-founder and founding president, FARA. "We want to extend our sincere appreciation to all of the patients, patient families and investigators who were a part of this study as well as Horizon for collaborating with us so impressively on this important research."
The announcement today does not impact Horizon Pharma's full-year 2016 adjusted net sales or adjusted EBITDA guidance, and the Company believes it is well-positioned for growth in 2017 and beyond based on its existing portfolio of medicines.

The primary endpoint evaluated the effect of ACTIMMUNE versus placebo on the change from baseline to Week 26 in neurological outcome as measured by the modified Friedreich's Ataxia Rating Scale (FARS‐mNeuro), a subset of the total FARS score that measures objective components of a patient's ability to function such as upper and lower extremity coordination. The FARS is a validated neurological outcome scale, in which higher scores reflect a greater level of disability. FARS-mNeuro was determined by experts in the field to be the most clinically relevant instrument for assessing the effects of treatment on FA in this particular trial. Secondary endpoints included observed mean change from baseline to week 26 in Activities of Daily Living (ADL), Timed 25-foot Walk Test (T25FW), Friedreich's Ataxia Rating Scale (FARS) scores, and other neurologic evaluations. In addition to safety and efficacy, the STEADFAST trial evaluated the pharmacokinetic characteristics of ACTIMMUNE in people with FA.
About Friedreich's ataxia (FA)
FA is a debilitating, life-shortening and degenerative neuro-muscular disorder that affects approximately 4,000 to 6,000 people in the United States. Onset of symptoms can vary from five years old to adulthood, with the childhood onset tending to be associated with a more rapid progression. Symptoms include progressive loss of strength and coordination usually leading to wheelchair use; diminished vision, hearing and speech; scoliosis (curvature of the spine); increased risk of diabetes; and a life-threatening heart condition. Most young people diagnosed with FA require mobility aids such as a cane, walker or wheelchair by their teens or early 20's. There are currently no approved treatments for FA.
ACTIMMUNE (interferon gamma-1b) is a biologically manufactured protein similar to one the body makes naturally to help prevent infection. ACTIMMUNE is currently approved by the U.S. Food and Drug Administration (FDA) for use in two rare diseases. It is indicated for reducing the frequency and severity of serious infections associated with Chronic Granulomatous Disease (CGD), a genetic disorder that affects the functioning of some cells of the immune system. In addition, ACTIMMUNE is indicated for delaying time to disease progression for patients with severe, malignant osteopetrosis (SMO), a genetic disorder that affects normal bone formation.

ACTIMMUNE is not indicated for FA.
