LAS VEGAS — Fremanezumab may be efficacious for the prophylaxis of chronic migraine in individuals with comorbid migraine and moderate/moderate to severe depression. The treatment may also improve symptoms of depression, according to a study presented during the 2018 PAINWeek conference, held September 4-8. This multicenter phase 3 double-blind randomized study included 1130 participants between the ages of 18 and 70 who had been diagnosed with chronic migraine. Researchers randomly assigned patients at a 1:1:1 ratio to receive quarterly fremanezumab (baseline dosage, 675 mg; weeks 4 and 8, placebo), monthly fremanezumab (baseline dosage, 675 mg; weeks 4 and 8, fremanezumab 225 mg), or placebo over a 12-week period.

Chronic migraine was defined as at least 15 monthly headache days and at least 8 monthly migraine days. Moderate to moderately severe depression was defined as a baseline score between 10 and 19 on the 9-item Patient Health Questionnaire.

Of all the participants, 219 had comorbid depression that ranged from moderate to moderately severe (n=74 in the quarterly group; n=88 in the monthly group; n=57 in the placebo group). Treatment with fremanezumab was found to reduce the number of mean monthly headache days in participants with comorbid chronic migraine and depression (quarterly fremanezumab, -5.4±0.79; monthly fremanezumab, -5.6±0.75) when compared with placebo (-2.2±0.84; P <.001 for both). 

The mean number of migraine days also showed improvement (P <.001), as did the mean 9-item Patient Health Questionnaire score, which was reduced at the 12-week time point from baseline (quarterly fremanezumab, –10.5±0.68, P <.05; monthly fremanezumab, –9.5±0.63; placebo, -8.7±0.71,).  “[Fremanezumab] demonstrated efficacy in preventive treatment of [chronic migraine] in patients with comorbid moderate to moderately severe depression, reducing migraine and headache frequency and improving depression,” concluded the study authors.
