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.
