A Study of Home-Delivered Neurostimulation for Migraine

Not Applicable

Completed

Conditions: Migraine Disorders

Interventions: Device: non-invasive transcranial direct current stimulation (tDCS)

Registration Number: NCT03874351

Lead Sponsor: MJHS Institute for Innovation in Palliative Care

Brief Summary: There is a need for better preventive and abortive therapies for migraine. Previous research has indicated that non-invasive neurostimulation may have prophylactic effects on migraine and improve symptoms and functional outcomes in migraineurs. One such method is a non-invasive transcranial direct current stimulation (tDCS). This double-blind randomized sham-controlled two-parallel-arm study aims to evaluate efficacy and safety of tDCS self-delivered in daily 20-minute applications for 2 months (60 days) by adult migraine patients at home for migraine prevention and migraine symptom management, as compared to sham tDCS application; and to evaluate patients' satisfaction with the procedure.

Detailed Description: This study will employ a double-blind randomized sham-controlled two-parallel-arm design and involve 60 adults with migraine. For each participant, the study will involve 3 study visits and last about 90 days (30 days of the baseline followed by 60 days of the tDCS/sham study intervention). A post-study safety monitoring will continue bi-weekly by phone for 30 days after the last tDCS/sham application.

At Visit 1, patients will provide written informed consent and undergo screening for the eligibility. This will be followed by 30 days of baseline at home during which patients will keep daily records (Daily Diaries) of migraine occurrence and provide answers to a set of symptom-related questionnaires. Patients with 4 or more migraine days per month who fully meet the study eligibility criteria at the end of the baseline period will be randomized in double-blind manner into two groups: Group 1 will be randomized to receive active tDCS in daily 20-minute applications for 60 days; Group 2 will be randomized to receive sham tDCS in daily 20-minute applications for 60 days, self-applied at home. Following randomization, patients will continue keeping the Daily Diaries and Visit #2 will be held either in the patient's home or in the research facility, based on the patient's preference. tDCS device will be deployed to the patient and instructions on tDCS use will be provided. The first tDCS/sham self-application by the patient will be done at Visit 2. Daily tDCS/sham self-application by the patient at home and records in the form of Daily Diaries will continue for the rest of the 60-day period. Study staff will be in regular remote contact with the patient via phone and/or HIPAA-compliant videoconferencing. Upon conclusion of the intervention, Visit 3 will be held either in the patient's home or in the research facility, based on the patient's preference. tDCS device will be collected from the patient. Safety monitoring will continue bi-weekly by phone for 30 days after the last tDCS/sham application.

Outcome assessment will be carried out at the end of the baseline, and at Day 30 (the secondary time-point) and Day 60 (the primary time-point) of the tDCS/sham intervention.

Study & Design

Study Type: INTERVENTIONAL

Study Design: PARALLEL

Arm && Interventions

Group	Intervention	Description
Sham tDCS	non-invasive transcranial direct current stimulation (tDCS)	Thirty seconds of direct current at 1.5 mA, followed by 0 mA for the remaining time of the 20-minute stimulation period.
Active tDCS	non-invasive transcranial direct current stimulation (tDCS)	Twenty minutes of direct current at intensity of 1.5 milliamperes (mA).

Primary Outcome Measures

Name	Time	Method
Migraine Days Per Month	Baseline, Day 30 of the intervention (secondary time point), Day 60 of the intervention (primary time point);	A migraine day is defined as any calendar day on which the patient had onset, continuation, or recurrence of a migraine as recorded in the diary. A migraine is defined as a migraine (with or without aura) lasting at least 30 minutes. Any calendar day on which acute migraine medication is used is counted as a migraine day.

Secondary Outcome Measures

Name	Time	Method
Migraine Attack Frequency	Baseline, Day 30 of the intervention, Day 60 of the intervention	Median change in number of attacks per 30-day period, determined from the patients' diaries
Change in Quality of Life: The Migraine Specific Quality of Life Questionnaire (MSQ)	Baseline, Day 30 of the intervention, Day 60 of the intervention;	Determined from ratings on the migraine-specific MSQ questionnaire. The questionnaire consists of 14 items, each rated on a scale 1-6, with the total score ranging between 14 and 84. Higher scores reflect poorer quality of life.
Percentage of Responders	Day 60 of the intervention	determined as a percentage of patients having at least 50% reduction of monthly migraine days between the one-month baseline and post-intervention, in each of the two study groups
Acute Medication Use	Baseline, Day 30 of the intervention, Day 60 of the intervention	Acute antimigraine drug use per month determined from the patient's diaries. Median change in number of days on which an acute medication was used.
Tolerability of the Study Intervention: Number of Side Effects and Adverse Events	from Day 1 of the study intervention to the end of the safety follow-up thirty days after the last tDCS application	Determined as number of side effects and adverse events related, probably related or possibly related to the study intevention
Change in Headache Attack Intensity Median Change in NRS From Headache Days in a 30 Day Period	Baseline, Day 30 of the intervention, Day 60 of the intervention;	Determined from the 11-point \[0-10\] Pain Numerical Rating Scale (Pain NRS) on migraine days in the patients' diaries. Higher ratings on the Pain NRS reflect higher intensity of pain.
Change in Depressive Symptoms	Baseline, Day 30 of the intervention, Day 60 of the intervention;	Determined from the Hamilton Depression Scale (HamD) that consists of 21 items with numerically rated responses ranging 0-2 or 0-4. Higher Ham-D score reflects more severe depression.
Patient's Satisfaction: 8-item tDCS User Survey	Day 60 of the intervention	Patient's satisfaction with the study intervention determined from the 8-item tDCS User Survey at the end of the intervention. Each item of the Survey is a brief statement and a respondent indicates if s/he Strongly Agree, Agree, Neither Agree or Disagree, Disagree or Strongly Disagree with the statement. Higher number of Agree/Strongly Agree ratings reflects higher satisfaction with the tDCS procedure.
