About

Migraine is a common neurologic with attacks of headache and associated symptoms such as nausea, vomiting, phono and photophobia. Migraine can lead to substantial functional impairment. This study intends to demonstrate the safety and efficacy of the Nerivio for migraine prevention.

The study is a prospective, randomized, double-blind, sham-controlled, multicenter study, conducted in three phases.

The study will consist of a screening/enrollment visit, followed by a 4-week (28 days) baseline phase, an 8-week double-blind preventive treatment phase, and a 4-week open-label phase.

Patients will complete an electronic diary throughout the study; this includes a daily evening report (completed regardless of whether the patient had a headache) and treatment feedback during the follow-up pre-emptive phase.

The primary endpoint is the mean change in the average of migraine headache days per month comparing the 4-week baseline phase (weeks 1 through 4) with the last 28 days of the treatment phase (weeks 9 through 12).

Full description

Nerivio is a neuromodulation device approved for the acute treatment of migraine with or without aura in patients 12 years of age or older. The device utilizes electro stimulation to achieve conditioned pain modulation (CPM). CPM stimulate endogenous analgesic mechanism. Treatments are self-administered by the user at the onset of a migraine attack. this study intends to demonstrate the safety and efficacy of the Nwrivio for migraine prevention.

The study is a prospective, randomized, double-blind, sham-controlled, multicenter trial, conducted in three phases. The ratio between treatment and control groups will be 1:1, stratified by center and patient type (chronic/non-chronic). The study will consist of a screening/enrollment visit, followed by a 4-week (28 days) baseline phase. Eligible participants will enter an 8-week double-blind preventive treatment phase. Following the preventive treatment phase, patients will be offered to participate in a 4-week open-label pre-emptive treatment phase or continue their prevention treatment with an active device, according to their eligibility.

Phase I - Baseline - 4 weeks (weeks 1 through 4):

Eligible participants will install the Nerivio app on their smartphones and will be instructed to record daily their migraine/headaches symptoms and medication use on the Nerivio app.

Transition to the treatment phase: Participants who meet the following criteria in the baseline phase will be eligible to continue to the treatment phase:

Complete the diary in at least 22 out of the 28 days during the baseline phase (80%)
Have between 6 to 24 headache days during the 28-day baseline period
At least 4 of their headache days during the baseline phase fulfill the International Classification of Headache Disorders 3rd edition (ICHD-3) criteria for migraine (migraine without aura [code 1.1; C and D] or with aura [code 1.2; B and C], or probable migraine, or headaches requiring the use of migraine-specific medications including triptans, gepants or ergot derivatives).

Phase II - treatment phase (prevention) - 8 weeks (weeks 5 through 12):

Participants who meet the baseline phase requirements will be randomized in a 1:1 ratio to active and sham groups. Participants will be instructed to complete a daily diary (in the Nerivio app) about their headaches, associated symptoms, and medication use. They will also be instructed to conduct a 45-minute treatment with Nerivio every other day.

Transition to the follow-up phase (open label):

At the end of the treatment phase, participants from both arms (active and sham) may continue to a follow-up phase in which they will receive an active device that can be used during this phase. The data of all participants will be used for safety analyses.

The data of participants from the baseline and treatment phases will be used to assess their eligibility to participate in the pre-emptive follow-up phase. Participants eligible for the follow-up phase meet the following conditions:

Between 6-16 headache days during the baseline phase.
Participants experience prodrome symptoms within 24 hours prior to the onset of their migraine headache in at least half of their migraine attacks during the baseline phase.
Participants completed the daily questionnaires in at least 70% of the days during the treatment phase.
Treated every other day in at least 24 and less than 33 days during the 56 days of the treatment phase.

All adverse events will be reported.

Phase III - Follow-up phase (open label) - 4 weeks (weeks 13 through 16):

All participants will receive an active Nerivio device to use during the follow-up phase. Participants who do not meet the above requirements will be able to enter into the safety follow-up and continue to use Nerivio every other day for the preventive treatment of migraine. They will be instructed to compete a daily diary as was done in the treatment phase.

Participants who meet the above requirements will enter the pre-emptive follow-up phase and be instructed to conduct a 45-minute device treatment within 60 minutes of prodrome symptom onset. Participants will be instructed to complete questionnaires regarding their headache, prodrome symptoms, and medication use at baseline (start of treatment), 2 hours post-treatment, and 24 hours post-treatment. In addition, participants will be instructed to continue to report the daily diary, as performed in the other phases of the study.

All adverse events will be reported.
