9 Neurogenic Origin of Muscle Cramping/Spasms Cramps and spasms are generally NOT caused by dehydration, lactic acid build-up or electrolyte imbalances affecting the muscle •  Muscle cramping is caused by excessive firing of alpha-motor neurons in the spinal cord, which trigger a painful contraction of the muscle •  Repetitive muscle use induces hyperexcitability of alpha-motor neurons, causing them to fire excessively and trigger cramping Alpha-motor neuron Hyperexcitability of alpha-motor neurons is also a likely basis for spasticity and spasms

26 A MUSCLE CRAMP IS A FAILURE IN NEURO MUSCULAR PERFORMANCE BRAIN SPINAL CORD MUSCLE RECEPTORS Signals from the brain to the spinal cord balance the activity of motor neurons Alpha motor neurons, residing in the spinal cord, are what control the contraction of muscles If alpha motor neurons become hyper- excitable and start to fire repetitively, a muscle cramp can occur

 
27 NMP Neuro Muscular Performance refers to consistent, and closely integrated function of nerves and muscles. It’s how an athlete’s nerves and muscles work together in an optimal way. HOTSHOT boosts your NMP to stop muscle cramps by treating the nerve. When you’re cramp free you can push harder, train longer, finish stronger. We continue to study the poten,al benefits of improved Neuro Muscular Performance.

34 NLC Key Learnings: Topical Neurostimulation of TRPA1 & TRPV1 Channels Reduces Muscle Cramping in Humans Efficacy Signals Warrant Further NLC Development •  FLX-787 has shown positive signals on muscle cramping in the parallel design portion of two exploratory human proof-of- concept NLC studies. •  FLX-787 has shown a sigmoidal dose-response curve in a human electrically-induced cramp model. •  FLX-787 thus far is well tolerated and safe, and no SAEs have been reported. Key Learnings •  Patient selection and data capture & monitoring are critical issues of focus in the upcoming clinical studies. •  Given potential carry-over effects in cross-over studies, and consistent with FDA guidance, future FLX-787 studies in NLC will be parallel design. Next Steps •  Initiate IND-opening Phase 2 parallel design study in H1 2017, after the IND has been accepted.
