Flex Pharma, Inc. (NASDAQ: FLKS), focused on developing treatments for cramps and spasms associated with the severe neurological diseases of amyotrophic lateral sclerosis (ALS), multiple sclerosis (MS) and peripheral neuropathies such as Charcot-Marie-Tooth (CMT), today announced that the Company's investigational new drug (IND) application for FLX-787 for patients with ALS is effective which allows the Company to commence its U.S. Phase 2 clinical trial of FLX-787 in ALS patients who suffer from cramps as a consequence of the disease. The Company expects to begin enrolling US patients this summer in this randomized, controlled, double-blinded, parallel design study, referred to as the COMMEND trial. In addition, the Company has exploratory Phase 2 studies currently ongoing in patients with MS and ALS in Australia. FLX-787 is a small molecule co-activator of the TRPA1 and TRPV1 ion channels, and has been shown to prevent and reduce the frequency and intensity of muscle cramps in a human model of electrically induced cramps.
“This open IND for FLX-787 allows us to initiate this Phase 2 multi-center trial, representing an important milestone for Flex Pharma and starts the process of investigating other orphan indications in neurology where cramps, spasms and spasticity impact patients every day,” said Flex Pharma Chief Medical Officer Thomas Wessel, M.D., Ph.D. “Based upon encouraging results in prior randomized, controlled studies of FLX-787 in models of muscle cramping in healthy volunteers, we are excited to advance FLX-787 into this Phase 2 clinical trial for ALS this summer.”
“Muscle cramps can have a severe impact on functional performance and quality of life for patients with motor neuron diseases like ALS,” indicated lead investigator Dr. Björn Oskarsson of the Mayo Clinic in Jacksonville, Florida. “Neurologists are often confronted with a situation where the patient experiences symptoms, and current treatments are either ineffective or have limiting potential side effects. Flex Pharma’s FLX-787 may provide a better approach to this challenging problem.”
“Very shortly, we also plan to submit a protocol to the IND for a clinical trial of FLX-787 to treat patients with CMT, which would enable us to begin another Phase 2 this summer, making FLX-787 one of the most advanced novel compounds in development for CMT,” said Flex Pharma R&D President Bill McVicar, Ph.D. “Together with our ongoing exploratory Phase 2 studies in MS and ALS in Australia, we are focused on the execution of these studies and expect to have several data readouts in 2018.”
COMMEND Trial Design
This Phase 2 clinical trial is designed to evaluate FLX-787 in patients with motor neuron disease (MND), focused on ALS, who suffer from cramps. This randomized, controlled, double-blinded, parallel design trial in the US will include a run-in period to establish a baseline in cramp frequency. Patients will then be randomized to 30 mg of FLX-787 administered three times a day or control, for 28 days. Patients will be evaluated for changes in cramp frequency as the primary endpoint, with a number of secondary endpoints.
