Clinical Trial and Adverse Reactions

eNeura completed a clinical study in Headache Centers in the United States designed to support safety and effectiveness of the device for the acute treatment and prophylaxis of migraine headache. Baseline medication and symptoms were recorded for 28 days via patient diary. Subjects were instructed to use the device daily (morning and evening) and for the acute treatment of attacks for three months with no change in preventive medication. Study results showed statistically significant reduction in migraine headache days of 2.8 days from a baseline mean of 9.1 days. Forty-six percent of the patients saw at least a 50% reduction in headache days (responder rate). Reduction in acute medication was 2.9 days. A statistically significant improvement in quality of life was reported. Six patients reported using prophylactic medications at baseline (2.8%), of these, 5 were using topiramate and propranolol.
The efficacy of the eNeura device for prophylactic treatment is based on the result of an open label study. In open label studies, bias may affect the result. Additionally, open-label studies may introduce placebo rates of 10-25%.
This is consistent with placebo rates reported in Randomized Controlled studies for migraine prevention.
For further information about the clinical trial and any adverse reaction, please contact eNeura at 1-833-499-9300, option 1 or consult your prescribing physician.
