LA JOLLA, Calif., Jan. 14, 2015 (GLOBE NEWSWIRE) -- Auspex Pharmaceuticals, Inc. (Nasdaq:ASPX), a biopharmaceutical company dedicated to developing innovative medicines for people with movement disorders and other rare diseases, today announced that the U.S. Food and Drug Administration (FDA) has granted orphan drug designation to Auspex's investigational compound SD-809 for the treatment of Tourette syndrome in the pediatric population (defined as zero through 16 years of age). Auspex is currently evaluating the preliminary efficacy, pharmacokinetic and safety profile of SD-809 in a Phase 1b clinical trial for the treatment of tics associated with Tourette syndrome. Topline data from this trial are expected by mid-2015. In November 2014, SD-809 was granted orphan drug designation by the FDA for the treatment of Huntington's disease.
"Receiving orphan drug designation of SD-809 for the treatment of Tourette syndrome, in addition to Huntington's disease, is an important step forward in our goal of bringing this novel treatment approach to the patients and families affected by these serious disorders," said Pratik Shah, president and CEO of Auspex. "There have been no new drugs developed for Tourette syndrome in over 30 years. The orphan drug designation recognizes the significant need that exists among children living with this debilitating disease, and we look forward to assessing the potential role that SD-809 may have in addressing that."
The FDA's Orphan Drug program offers orphan status to drugs and biologics that are intended for the treatment of rare diseases affecting fewer than 200,000 people in the U.S. The designation provides sponsors with development and commercial incentives for designated compounds and medicines, including eligibility for a seven-year period of market exclusivity in the U.S. after product approval, FDA assistance in clinical trial design and an exemption from FDA user fees.
About Tourette Syndrome
Tourette syndrome is a hyperkinetic movement disorder manifested by motor and phonic tics, which are often accompanied by neurobehavioral disorders such as attention-deficit hyperactivity disorder and obsessive-compulsive disorder. Tics can be simple, such as blinking, eye rolling, nose twitching, head nodding and mouth pouting, or more complex, such as touching, squatting, jumping or hopping. Tics can result in significant long-term social, legal and developmental consequences for patients, as well as injury and physical disability including pain and secondary neurological deficits. In the U.S., an estimated 100,000 children have tics associated with Tourette syndrome. According to the U.S. Centers for Disease Control and Prevention, 37% of these children have moderate to severe forms of Tourette syndrome. The mean age of onset is at four to six years, with peak severity around 12 years of age, with an estimated 13% to 22% of affected children continuing to take medications for tics as adults. There have been no new drugs introduced for treating tics associated with Tourette syndrome in more than 30 years and we believe that physicians consider the two approved neuroleptics to be inadequate. These treatments carry, among other adverse events, the risk of causing permanent neurologic deficits, such as tardive dyskinesia.
