Alcobra Announces Enrollment of First Patient in Phase IIb Clinical Trial of MDX in Fragile X Syndrome

TEL AVIV, Israel, Aug. 19, 2014 (GLOBE NEWSWIRE) -- Alcobra Ltd. (Nasdaq:ADHD), an emerging pharmaceutical company primarily focused on the development and commercialization of its proprietary drug candidate Metadoxine Extended Release (MDX), to treat cognitive dysfunctions, such as ADHD and Fragile X Syndrome, announced today that the first patient has been enrolled in a Phase IIb Fragile X study of MDX. The FDA granted "Orphan Drug" designation to Metadoxine in the treatment of Fragile X Syndrome in December 2013.

The Phase IIb Fragile X trial is a multi-center, randomized, placebo-controlled study and is being conducted in 11 clinical sites, primarily in the U.S. It is designed to investigate MDX for 6 weeks compared with placebo in 60 adolescent and adult subjects with Fragile X Syndrome.

"We are pleased to start enrolling patients into our Phase IIb clinical study for MDX in Fragile X Syndrome," said Dr. Yaron Daniely, President and Chief Executive Officer of Alcobra. "Our interest in Fragile X Syndrome is based on a comprehensive data set demonstrating significant improvements in learning, social and cognitive functions in a pre-clinical model of the disease. In addition, data supporting MDX modulation of the GABA/glutamate circuit and its rapid and significant effect on attentional capabilities in the ADHD population suggest a potential benefit in the Fragile X population. Our goal is to complete patient enrollment and report top-line data in the 4th quarter of 2014."

"We expect that this study will give us important insights into the efficacy and safety of MDX in Fragile X Syndrome," said Elizabeth Berry Kravis, MD, PhD, Associate Professor of Biochemistry, Neurological Sciences, and Pediatrics at Rush University Medical Center, and the Principal Investigator of the Phase IIb study. "Fragile X Syndrome is a genetic condition that causes intellectual disability, and is the leading known genetic cause of autism. There are no approved treatments for Fragile X Syndrome, so the development of MDX in this indication has the potential to address a significant unmet need."
