BOSTON--(BUSINESS WIRE)--Flex Pharma, Inc. (NASDAQ: FLKS), a biotechnology company developing innovative and proprietary treatments for nocturnal leg cramps (NLC), spasms associated with severe neuromuscular conditions such as multiple sclerosis (MS) and amyotrophic lateral sclerosis (ALS), and exercise-associated muscle cramps (EAMC), today reported financial results for the quarter ended June 30, 2016 and provided an update on its clinical development, consumer product launch and corporate activities.

"The clinical and consumer arms of the business continue to advance. With our single agent molecule TRP ion channel activator, we initiated and completed enrollment, well ahead of plan, in our human efficacy NLC study. Additionally with FLX-787, we initiated our Phase 2 MS study, and expect to start our Phase 2 ALS study in the coming months. We are also pleased with the solid launch of HOTSHOTTM, the first scientifically proven consumer product to prevent and treat exercise-associated muscle cramps, which is exceeding our initial expectations," stated Christoph Westphal, M.D., Ph.D., Chair and CEO of Flex Pharma. "Flex is well funded through the middle of 2018, with approximately $75 million in cash and investments at quarter end, and well-positioned to execute upon our mission of helping patients and consumers."

“Flex Pharma is developing the leading pharmaceutical agent for nocturnal leg cramps. The rapid enrollment in our NLC study underscores the substantial unmet need for the millions of people who suffer from this painful condition and currently have no safe and effective therapeutic options,” said Flex Pharma Chief Medical Officer Thomas Wessel, M.D., Ph.D., who served as the medical lead for three products approved in the United States: Razadyne®, Lunesta® and Ampyra®. “We are supplementing our NLC development program by running an additional, small, dose-ranging, randomized, controlled, cross-over study of the single molecule TRP activator. Preliminary interim results are promising. We anticipate providing more details from this added human efficacy study in the fall.”

“Chemical Neuro Stimulation is the process whereby small molecules activate TRP ion channels topically, which we hypothesize leads to sensory stimulation that in turn reduces hyperexcitability in motor neurons at multiple levels in the spinal cord,” said Dr. Rod MacKinnon, Nobel Laureate and Flex Pharma Scientific Co-Founder, Board Member, and Scientific Advisory Board Co-Chair. “Because we believe there are common underlying mechanisms at play, the data generated over the past year support our belief that our treatments have the potential to benefit a large number of people afflicted by cramps and spasms."

Recent Business Highlights

• Clinical Efforts
  • On July 26, 2016, the Company announced the completion of enrollment, well ahead of plan, in a human proof-of-concept efficacy study in NLC which was initiated in May. The randomized, blinded, controlled, cross-over study is designed to evaluate the safety and efficacy of its single agent - a chemically synthesized, single molecule, transient receptor potential (TRP) ion channel activator, formulated as an orally disintegrating tablet - in over 50 subjects who suffer from nocturnal leg cramps on a frequent basis.
  • In June 2016, the Company initiated a Phase 2 efficacy study in MS patients in Australia. The randomized, controlled, blinded, cross-over study is designed to evaluate the safety and efficacy of FLX-787, the Company’s single molecule, chemically synthesized, TRP ion channel activator, in up to 50 patients who suffer from cramps, spasms and/or spasticity as a consequence of MS.
  • The Company expects to initiate a Phase 2 efficacy study in ALS patients in Australia in the coming months. The randomized, controlled, blinded, cross-over study is designed to evaluate the safety and efficacy of FLX-787, the Company’s single molecule, chemically synthesized, TRP ion channel activator, in up to 50 patients who suffer from cramps, spasms and/or spasticity as a consequence of ALS.
  • In April 2016, the Company presented results from its positive human NLC study, which was selected as one of only 14 abstracts for late-breaking presentations at the American Academy of Neurology (AAN) Annual Meeting. In this randomized, controlled, blinded study of subjects with frequent nocturnal leg cramps, the Company’s extract formulation demonstrated statistically significant positive human efficacy on multiple key endpoints: muscle cramp frequency (p<0.05); cramp-free days (p<0.01); the physician-rated Clinical Global Impression of Change (CGI-C) (p<0.01); specific sleep disturbance measures (p<0.05); and specific pain measures (p<0.01). The positive effects were seen across a broad range of enrolled subjects; in addition, a subset of patients showed pronounced benefit. Additionally, the product appeared to be safe and well-tolerated and there were no serious adverse events reported. The topline results from this study were first reported in February 2016.
• Consumer Product Launch
  • In April 2016, leading academics at The Pennsylvania State University (PSU) presented a positive effect of the Company’s proprietary formulation on athletic human muscle cramps at the Experimental Biology conference. The Company’s proprietary consumer product formulation showed a statistically significant benefit in reducing muscle cramps in athletes as compared to vehicle control (as measured by the intensity-duration profile of voluntarily induced muscle cramps).
  • On June 2, 2016, the Company announced the launch of its cornerstone consumer product, HOTSHOTTM, the first scientifically proven formula to prevent and treat muscle cramps, on its branded website www.TeamHOTSHOT.com. The product also became available at select specialty retailers in Boston, Boulder and Los Angeles.

  • At the American College of Sports Medicine (ACSM) Annual Meeting in Boston on June 2, 2016, Bruce Bean, Ph.D., Harvard Medical School Professor of Neurophysiology, Flex Pharma Co-Founder and Scientific Advisory Board Co-Chair, and Tom Wessel, M.D., Neurologist and Flex Pharma Chief Medical Officer, discussed this breakthrough in sports science during the symposium, “Etiology and Treatment of Exercise Associated Muscle Cramps.”
  • During the week of July 11th, The Wall Street Journal published the article, “A New Way to Prevent Muscle Cramps”, discussing our breakthrough science behind HOTSHOTTM. The article was a top ranked story on wsj.com for a week. HOTSHOTTM has also been featured in several recent publications: Wired.com, Men’s Fitness online, LAVA Magazine (official magazine of IRONMAN®), Esquire online and The Daily Burn.
