Cabergoline for Episodic Migraine

Recruiting now · Phase 2 · Has a placebo group

Conditions studied: Migraine

In brief

The goal of this randomized, placebo-controlled, double-blind clinical trial is to evaluate the efficacy, safety, and tolerability of cabergoline for the prevention of episodic migraine in adults with 4-14 monthly migraine days (MMD). The main questions it aims to answer are: 1. Does once-weekly cabergoline (0.5 mg or 1.0 mg) reduce MMD compared to placebo? 2. What are the effects of cabergoline on headache severity, acute medication use, and patient-reported outcomes? 3. Is cabergoline safe to use in individuals with migraine? Participants will: Complete a 4-week baseline period to document migraine frequency and classify headache days. Be randomly assigned to one of three treatment arms: 1. Cabergoline 0.5 mg/week 2. Cabergoline 1.0 mg/week 3. Placebo Participate in a 12-week double-blind treatment phase, followed by a 12-week open-label treatment phase where all participants receive cabergoline (0.5 mg or 1.0 mg once weekly). Record daily headache activity, acute medication use, and severity using an electronic diary. Complete validated headache questionnaires and provide blood samples for biomarker analysis at baseline, week 12, and week 24. The study also includes exploratory analyses of genetic predictors of treatment response and metabolic markers to assess the broader effects of cabergoline.
