Home-based Biofeedback for the Prevention of Migraine

Not Applicable

Completed

• Conditions: Migraine
• Interventions: Device: Cerebri biofeedback; Other: Cerebri headache diary

• Registration Number: NCT05616741
• Lead Sponsor: Nordic Brain Tech AS

Brief Summary

The goal of this clinical trial is to test an app-based biofeedback treatment in adults with migraine. The aim of the study is to investigate the safety and effectiveness of biofeedback treatment using the medical device Cerebri, compared to wait-list controls.

Participants will perform 10 minutes biofeedback daily, in addition to daily registrations in the headache diary. Wait-list controls will complete daily registrations in the headache diary during the same period.

Researchers will compare the reduction in the number of days with migraine from baseline per 28-day period between treatment group and the wait-list group.

Detailed Description

This trial, BioCer, is a clinical study to test the effectiveness and safety of the app-based biofeedback treatment, Cerebri, for migraines in adults. Bodily signals that are thought to be associated with migraines are measured by sensors during biofeedback. During the treatment, one sensor is attached to the shoulder to measure activity in the shoulder and neck muscles and one sensor is attached to the index finger to measure temperature and heart rate variability. By getting on-screen feedback on the phone, the user can learn techniques to reduce muscle tension, and increase finger temperature and heart rate variability. Reduced muscle tension, as well as an increase in finger temperature and heart rate variability is a sign of relaxation and a deactivation of the nervous system, which can lead to fewer and less serious migraine attacks. The aim of the study is to investigate the safety and effectiveness of biofeedback treatment using Cerebri compared to wait-list controls.

In this study, the investigators will recruit 286 adults with episodic migraines. All participants will complete one month of daily headache diary entries in the Cerebri app without any specific treatment. This will serve as the "baseline" measurements. Subsequently, the participants will be randomized to either the treatment group or the wait-list group. The treatment group will conduct daily biofeedback sessions of 10 minutes duration for 12 weeks. The wait-list group does not receive any specific treatment for 12 weeks but serves as an important basis for comparison to evaluate the treatment effect. The wait-list control group will be offered active treatment for 12 weeks after the initial 12-week wait-list period is completed. Participants in both groups (the treatment group and the wait-list control group) must complete daily registrations in the headache diary included in the app.

The primary endpoint of the study is the change in the number of days with migraine per 28-day period. The reduction in the number of migraine days will be compared between the treatment group and the wait-list group. Secondary endpoints include the change in intensity of headaches, the change in consumption of acute medication for migraine, and the number of participants with at least a 30% reduction in the number of migraine days.

There is a wide range of preventive treatments for migraines, both drug and non-drug, but many have limited effects and potentially numerous side effects. If the biofeedback app proves to be effective, it may represent a useful and viable treatment option for episodic migraine patients, that is readily available and unlikely to cause unwanted side effects.

• Subjects diagnosed with trigeminal autonomic cephalalgias and neuralgias.
• Subjects with secondary headache conditions.
• Subject with pathologies that inhibit use of the device according to the instructions for use (e.g., blindness, deafness).
• Use of non-pharmacological preventive treatment (meditation, physical therapy, psychotherapy as a headache treatment, acupuncture, etc.), with the exception of stable treatment for other indications than migraine
• Use of concurrent migraine preventive medication, with the exception of stable dose (≥3 months) monotherapy of migraine preventive medication · Subjects who have previously attempted three or more prophylactic pharmacological treatments in adequate doses, without significant clinical effect.
• Subjects taking opioids (>3 days per month) or barbiturates at the time of screening.
• Subject participates in another clinical investigation or has participated in CER-MIG-1.
• Alcohol overuse or illicit drug use.
• Subject who is unlikely to follow Clinical Investigation Plan or where treatment seems futile in the opinion of the Investigator or have demonstrated an inability to sufficiently adhere to headache diary entries (<70%).

Primary Outcome Measures

Name	Time	Method
Efficacy of intervention in treatment group compared to the wait-list control group in reducing the frequency of migraine days	4 months	Change in the mean number of migraine days from baseline to the last 28-day period during the treatment phase, in the treatment group as compared to the wait-list control group

Early onset efficacy of intervention in treatment group compared to the wait-list control group in reducing the frequency of migraine days	4 months	Change in the mean number of migraine days from baseline to the first two 28-day periods during the treatment phase, in the treatment group as compared to the wait-list control group
Efficacy of intervention in treatment group compared to the wait-list control group in reducing migraine intensity	4 months	Change in the mean intensity of migraine/headache using 11-point scale (0-10), where high score means high migraine intensity. Change will be assessed from baseline to the last 28-day period during the treatment phase, in the treatment group as compared to the wait-list control group
Change in acute migraine drug use between the treatment and wait-list control groups	4 months	Change in acute migraine drug treatment use from baseline to the last 28-day period, in the treatment group as compared to the wait-list control group.
Change in subject-reported headache-related disability from baseline to treatment between the treatment and control groups	4 months	Change in subject-reported headache-related disability measured by Migraine-Specific Quality of Life Questionnaire version 2.1 (MSQ v2.1) from baseline to the last 28-day period, in the treatment group as compared to the wait-list control group. The MSQ v2.1 contains 14 questions from three domains with six response alternatives ranging from "none of the time" to "all of the time".
