Brief summary: This is a double-blind, placebo-controlled, randomized, multi-center study. Subjects agreeing to participate in the study and meet the entry criteria assessed at the screening visit, will begin a 28 day baseline period to confirm their diagnosis, as well as establish baseline migraine characteristics. During this baseline period, subjects will continue treating their migraines as usual, simply recording the information in a daily headache diary. Subjects who, after completing the baseline, continue to meet entrance criteria will be eligible to enter into the treatment phase and be randomized according to the Clinvest generated randomization schedule. Approximately 142 subjects (71 subjects per arm) will be randomized and enter the treatment phase receiving MLD10 or placebo in a 1:1 design at 6 United States sites. Diary assessments will collect study medication adherence, pain severity, headache symptoms, acute medication usage, and unusual symptoms. Serum samples will be collected and analyzed for ionized magnesium, electrolytes, and creatinine.

Detailed description: This is a multi-center, double-blind, randomized, placebo-controlled, parallel study of MLD10 for the prevention of migraine headache. The study population will consist of approximately 142 male and female subjects between 18 and 65 years of age with frequent episodic migraine as defined by International Classification of Headache Disorders-3beta criteria. Two MLD10 (243 mg (milligrams) of elemental magnesium) or placebo caplets will be taken twice daily for a total daily dose of 486 mg.
