About this study

Milnacipran is a serotonin norepinephrine reubtake inhibitor (SNRI) approved for the management of fibromyalgia in the United States.

Migraine and fibromyalgia have significant co-morbidity. Of 100 patients with fibromyalgia, 76% had chronic headaches, of whom 63% had migraine. Interestingly, general measures of pain, disability, sleep quality, and psychological distress were similar in individuals with fibromyalgia with and without headache. Conversely, the prevalence of fibromyalgia in women with migraine was reported as 22%, and at a headache referral center, 36% of headache patients had fibromyalgia.

Because of significant co-morbidity, as well as the likelihood of shared pathophysiologic mechanisms, there is reason to believe that a medication effective for fibromyalgia might reduce migraine pain, especially where the pain has taken on the nature of a chronic pain disorder, as in chronic migraine. The current study evaluated the benefits of milnacipran in individuals with chronic migraine.

Patients with chronic migraine were randomized to either Milnacipran or Placebo. Patients completed 30 days of baseline followed by 90 days of headache diaries while taking assigned medication. Primary outcomes were reduction in pain severity and improvement in migraine specific quality of life (MSQ) while secondary outcomes included reduction in migraine and non-migraine headache days and symptomatic use of medication for migraine. Independent sample t-tests were used to evaluate the changes in primary and secondary measures between the two groups.

Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • Individuals between the age of 18 and 65
  • Headache fulfills ICHD-2 criteria for: chronic migraine, or probable medication overuse headache where individual headaches meet criteria for migraine
  • At least 15 headache days/month and at least 8 migraine or probable migraine days/month for the past 3 months, by patient report (including days of headache relieved with a triptan or related compound).
  • Age at onset of chronic migraine < 60 years old

Exclusion criteria

  • Pregnancy or attempting conception
  • Unable to read or write English
  • Use of Opiates >/= 10 days per month
  • Subject has failed >/= 4 adequate preventive trials of antidepressant medications due to lack of efficacy; at least one trial included another SNRI.(An adequate preventive trial defined as at least 6 weeks on therapeutic dose [150mg of amitriptyline or nortriptyline or other tricyclic, 150mg of venlafaxine, 60mg of duloxetine])
  • Subjects on antidepressant medications, including SNRIs who cannot safely withdraw from those medications, in the assessment of the PI. Subjects on other headache preventives (beta blockers, antiepileptic drugs), at stable dose for at least three months, will be allowed to participate.

A. Subjects on other headache preventives may be included in the study if the medication has been at a stable dose for 3 months.

  • Presence of fibromyalgia or another pain or medical disorder that would make it difficult for patient to distinguish headache-related quality of life from overall health related quality of life.
  • Uncontrolled or unstable psychiatric disorder (PHQ-9 score or GAD-7 score >15 with sentinel questions >/=4, or in opinion of examiner), or anticipated need for change in psychotropic medications during duration of study period; or suicidality.
  • Chronic kidney disease, liver disease, or any poorly controlled medical condition

Primary outcomes

  1. Change in VAS Pain Severity

    Time frame: Baseline and 90 days

    On headache days, patients were instructed to complete a Visual Analog Scale (VAS) to rate their pain intensity. Their response (the scale was 100 cm long) was measured and assigned a score (0-100) with higher numbers indicating more severity. Scores were averaged over a 30 day period to create the score for a time period (baseline and 90 days). Change in Pain score = Score[Baseline] - Score[90 days]. Higher scores indicate greater pain reduction.

  2. Change in Migraine Specific Quality of Life - Restrictive

    Time frame: Baseline and 90 days

    The Migraine Specific Quality of Life measures the impact Migraine has on the patient's Quality of Life. The Restrictive subscale assesses the extent to which migraine restricts the patient's function. The subscale is measured on a standard scale from 0-100, where higher scores indicate better quality of life. For the outcome assessing change, higher positive scores indicate better outcomes.

  3. Change in Migraine Specific Quality of Life - Preventive

    Time frame: Baseline and 90 days

    The Migraine Specific Quality of Life measures the impact Migraine has on the patient's Quality of Life. The Preventive subscale assesses the extent to which migraine prevents the patient's function. The subscale is measured on a standard scale from 0-100, where higher scores indicate better quality of life. For the outcome assessing change, higher positive scores indicate better outcomes.

  4. Change in Migraine Specific Quality of Life - Emotional

    Time frame: Baseline and 90 days

    The Migraine Specific Quality of Life measures the impact Migraine has on the patient's Quality of Life. The Emotional subscale assesses the extent to which migraine influences the patient's emotional function. The subscale is measured on a standard scale from 0-100, where higher scores indicate better quality of life. For the outcome assessing change, higher positive scores indicate better outcomes.

Secondary outcomes

  1. Change in Days With Migraine Per Month From Baseline to 90 Days

    Time frame: Baseline and 90 days

    On days where the patient indicated they had a headache, patients were instructed to complete the diary questions regarding headache characteristics using International Headache Classification Diagnostics. This information was used to calculate migraine days per month. Days with migraine over a 30 day period were summed to generate a number for each time frame (baseline and 90 days). For the outcome measure, higher positive numbers indicate higher reduction of days with migraine.

    Change in days with migraine = Score[Baseline] - Score[90days]

  2. Change in Days With Non-Migraine Headache Per Month From Baseline to 90 Days

    Time frame: Baseline and 90 days

    On days where the patient indicated they had a headache, patients were instructed to complete the diary questions regarding headache characteristics using International Headache Classification Diagnostics. This was information was used to calculate non-migraine headache days days per month. Days with migraine over a 30 day period were summed to generate a number for each time frame (baseline and 90 days). For the outcome measure, higher positive numbers indicate higher reduction of days with non-migraine headache.

    Change in days with non-migraine headache = Score[Baseline] - Score[90 days]

  3. Change in Days Using Headache Medication Per Month From Baseline to 90 Days

    Time frame: Baseline and 90 days

    On days where the patient indicated they had a headache (i.e., migraine or non-migraine headache), patients were instructed to complete the diary questions regarding whether they used medication to treat headache pain and related symptoms. This was used to calculate days using headache medication days per month. Days with migraine over a 30 day period were summed to generate a number for each time frame (baseline and 90 days). For the outcome measure, higher positive numbers indicate higher reduction of days using headache medication per month.

    Change in days using headache medication = Score[Baseline] - Score[90 days]
