Flex Pharma Data Presented at AAN Platform Session

Company Presents Human Proof-of-Concept for Treating and Preventing Muscle Cramps

BOSTON--(BUSINESS WIRE)--Apr. 21, 2015-- Click to Tweet this News

Flex Pharma, Inc. (NASDAQ: FLKS), a biotechnology company that is developing innovative and proprietary treatments for exercise-associated muscle cramps, nocturnal leg cramps, and spasms associated with severe neuromuscular conditions, today announced that Flex Pharma Scientific Co-Founder, Dr. Bruce Bean, presented the Company’s data under the abstract he co-authored titled, “Orally-administered TRPV1 and TRPA1 activators inhibit electrically-induced muscle cramps in normal healthy volunteers,during an oral platform presentation at the American Academy of Neurology (AAN) 67th Annual Meeting being held in Washington, D.C.

Flex Pharma’s proprietary treatment is based on research showing that cramps are caused by excessive firing of alpha-motor neurons in the spinal cord that control muscle contraction. The treatment is designed to reduce the firing of the neurons by topically stimulating the transient receptor potential (TRP) ion channels located in the gastrointestinal tract. Physical properties of the TRP activators largely limit their action to sensory neurons in the mouth, esophagus and stomach, with minimal concentrations reaching the bloodstream and, consequently, fewer potential systemic side effects.

“Based upon the novel insight that topical neurostimulation via oral small molecules can act rapidly on the nervous system, we are excited that these results show that the Flex proprietary treatment is effective in reducing muscle cramping,” said Bruce Bean, Ph.D., Flex Pharma Scientific Co-Founder and Co-Chair of the Scientific Advisory Board. Dr. Bean is the Robert Winthrop Professor of Neurobiology at Harvard Medical School and is a member of the National Academy of Sciences. “Muscle cramping and spasticity are painful and debilitating symptoms of many neurological diseases, such as multiple sclerosis, spinal spasticity, and amyotrophic lateral sclerosis. In addition, muscle cramping is a disruptive condition for athletes and the estimated four million U.S. adults afflicted daily by nocturnal leg cramps.”

The studies evaluating this treatment consisted of three randomized, blinded, placebo-controlled crossover designs in a total of 37 healthy volunteers. The primary endpoint of each study was to evaluate the efficacy of the treatment in preventing muscle cramps. Each of the studies showed statistically significant results, demonstrating that Flex Pharma’s treatment reduced electrically induced muscle cramps within 15 minutes, and its effect lasted between six and eight hours compared to subjects taking a vehicle control. When data from the three studies were aggregated, the treatment showed a statistically significant overall treatment effect, reducing cramp intensity by three-fold compared to subjects taking a vehicle control (ANOVA, p<0.0001).
