Efficacy and Safety of Nerivio™ for Acute Treatment of Migraine in People With Chronic Migraine

Not Applicable

Completed

Conditions: Chronic Migraine

Interventions: Device: Nerivio

Registration Number: NCT04161807

Lead Sponsor: Theranica

Brief Summary: This study is intended to evaluate the efficacy and safety of Nerivio, an FDA-authorized remote electrical neuromodulation (REN) device for the acute treatment of migraine, for the acute treatment of migraine in people with chronic migraine. The device delivers transcutaneous electrical stimulation to the upper arm to induce conditioned pain modulation (CPM) that activates a descending endogenous analgesic mechanism. The study duration consists of a 4 weeks of active treatment with the device in about 40 patients.

Detailed Description: This open label study includes up to 2 visits. The enrollment and device training may occur in 2 separate visits.

First visit - The first visit will include screening, enrollment and training on the application and device.

Treatment phase - Participants will be instructed to use the device for the treatment of qualifying migraine headaches (see below) as soon as possible and always within 60 minutes of onset during a period of up to 4 weeks. Participants will be instructed to use the device with the intensity level identified during the device training visit (and adjust as necessary) and make sure the stimulation is perceptible but not painful. Participants will be instructed to avoid taking rescue medications within 2 hours post-treatment. If medications are used, participants will be instructed to record in the app when and which medication was taken at 2- and 24-hours post treatment. The participants will use the app to record pain intensity levels, the presence/absence of aura and associated migraine symptoms (nausea, photophobia, phonophobia, and allodynia l) as well as rate their stress level and functional disability at baseline, 2- and 24-hours post-treatment. At the beginning of each treatment, participants will also be asked to report the time elapsed from attack onset. Adverse events will be reported throughout this phase of the study directly to the site staff.

Participants who do not achieve satisfactory relief at 2 hours post-treatment may treat again with the Nerivio™ device or may treat with usual care at that time or any time thereafter if the headache does not resolve. Participants will also be able to treat headache recurrence with the device. Migraine headaches that are not treated with the device may be treated with usual care.

The first reported treatment will be considered a "training" treatment, aimed to verify that the participants use the device properly, and will only be included in the safety analysis. The efficacy evaluation will be performed on the first treatment of a qualifying attack (see below) following the training treatment (hereby termed "test treatment").

Second (final) visit - End of study:

Participants will return to the clinic following the end of the treatment phase, at which time they will return the device. The participants will have the option of returning the device by mail instead of an on-site visit.

Primary Outcome Measures

Name	Time	Method
Proportion of Participants With Reduction of Migraine Headache at 2 Hours Post Treatment	2 hours post-treatment	The proportion of participants reporting pain relief at 2 hours post-treatment without the use of rescue medication following the test treatment . Pain relief is defined as an improvement from severe or moderate pain to mild or no pain, or from mild pain to no pain.

Secondary Outcome Measures

Name	Time	Method
Proportion of Participants With Pain Disappearance at 2 Hours Post Treatment	2 hours post treatment	The proportion of participants reporting freedom from migraine pain at 2 hours post-treatment without medications following the test treatment. Pain freedom is defined as an improvement from severe or moderate or mild pain to no pain
Proportion of Participants With Disappearance of Photophobia at 2 Hours Post-treatment	2 hours post treatment	The proportion of participants reporting disappearance of photophobia at 2 hours post-treatment without rescue medications following the test treatment.
Proportion of Participants With Disappearance of Phonophobia at 2 Hours Post-treatment	2 hours post treatment	The proportion of participants reporting disappearance phonophobia at 2 hours post-treatment without rescue medications following the test treatment.
Proportion of Participants With Disappearance of Nausea and/or Vomiting at 2 Hours Post-treatment	2 hours post treatment	The proportion of participants reporting disappearance of nausea and/or vomiting at 2 hours post-treatment without rescue medications following the test treatment.
