8 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

12 Selected for podium presentation at AAN 2016 (only 1 of 14 late-breakers) •  Statistically significant effects demonstrated on multiple efficacy endpoints AAN 2016: Selected for Late-Breaking Presentation Positive Human Efficacy in Nocturnal Leg Cramps Figure 5. Percentage of participants who experienced at least a 25%, 50%, or 75% decrease in the total number of cramps over the two week study period. Those individuals receiving TRP-Stim demonstrated a more pronounced cramp reduction than Placebo in all groups, with only TRP-Stim showing a >75% reduction. •  The positive effects were seen across a broad range of enrolled subjects; in addition, a subset of patients showed pronounced benefit. Patient benefit appears clinically meaningful.

13 •  Treatment with TRP activators resulted in statistically significant effects on clinically meaningful endpoints:   cramp frequency (p<0.05)   cramp-free days (p<0.01)   physician-rated Clinical Global Impression of Change (p<0.01)   “difficulty staying asleep” (p<0.05)   VAS pain intensity over the last 3 days of each treatment period (p<0.01) •  The magnitude of efficacy in this study on reduction in muscle cramps appears similar to published “Class 1 level” quinine efficacy studies. •  Extract formulation was safe and well-tolerated; no SAEs reported. •  Chemical Neuro Stimulation of TRPV1 and TRPA1 channels in the oral mucosa may be a generally applicable method to treat disorders stemming from α-motor neuron hyperexcitability.

Larry Kenney, Professor at the Noll Laboratory at PSU Presented at Experimental Biology by PSU (April 2016) •  Oral consumption of a mixture of TRPV1 and TRPA1 agonists prior to exercise mitigated muscle cramp intensity and perceived soreness. •  Overall muscle activity during cramping (integrated area of EMG intensity-duration curve) was reduced with the active treatment. •  Self-reported ratings of muscle soreness were lower within the first 20 minutes after cramp cessation with the active treatment.
