Flex Pharma Collaborator Penn State Presents Positive Human Muscle Cramp Data

-- Presentation at Experimental Biology 2016 Conference Shows Positive Effect on Athletic Human Muscle Cramps --

BOSTON--(BUSINESS WIRE)--Apr. 6, 2016-- Click to Tweet

Flex Pharma, Inc. (NASDAQ: FLKS) announced today that results from a study showing that its proprietary formulation of TRPA1 and TRPV1 activators prevented volitional muscle cramps will be presented today at the Experimental Biology conference. In the study, run by leading academics at The Pennsylvania State University (PSU), the Company’s proprietary 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). Additionally, subject ratings of muscle soreness resulting from cramps were also lower compared to vehicle control. Flex Pharma is a biotechnology company developing innovative and proprietary treatments for exercise-associated muscle cramps, nocturnal leg cramps, and cramps and spasms associated with severe neuromuscular conditions.

“Muscle cramps interfere with athletic performance in many different sports. Our model of voluntarily initiated muscle cramps allows us to reliably trigger cramps and test various intervention strategies. The results we are presenting at Experimental Biology 2016 are striking in that they confirmed that oral TRP channel activators significantly reduced the intensity and duration profile of muscle cramps, consistent with results from studies that have evoked muscle cramps using electrical stimulation,” cited Dr. W. Larry Kenney, Professor of Physiology and Kinesiology at the Noll Laboratory at PSU. “As this volitional model more closely reproduces the effects of naturally occurring exercise-associated muscle cramps, I would expect these results to translate to the natural setting. I am not aware of any other consumer product that has demonstrated significant efficacy in mitigating muscle cramps in a rigorous double-blinded scientific study.”

To test this effect on voluntarily initiated calf muscle cramps, PSU researchers conducted a randomized, double-blinded, vehicle-controlled crossover study. Twenty subjects, males and females, ages 19-25 years, were able to consistently reproduce cramps voluntarily. Each of the 20 enrolled subjects was randomized, ingested either active or control, with cramp profiles measured by surface electromyography (EMG), and then subsequently crossed-over with a week between treatments.

“The research at the Noll Laboratory at PSU supports the development of our consumer product and complements our electrically-induced cramp model. These results confirm the utility of oral TRP channel activation as a rapid and effective method to prevent muscle cramps in athletes," commented Dr. Tom Wessel, Chief Medical Officer of Flex Pharma. “We believe that the benefits observed in athletes depend on the same underlying mechanisms in the central nervous system that reduce cramping in nocturnal leg cramps and potentially other conditions such as MS and ALS.”
