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. VISIT 1 - SCREENING The following will be completed at Visit 1: 1. Obtain written Informed Consent. The informed consent will be obtained in accordance with Good Clinical Practices (GCP) and all applicable regulatory requirements from each subject prior to participation in the study. 2. Verify Inclusion/Exclusion Criteria. Subjects will meet all the inclusion and none of the exclusion criteria. 3. Obtain demographics (race, ethnicity, sex, date of birth) 4. Obtain medical, medication, and headache history. Data collected will include medical history and diagnoses, age at onset of migraine and other pertinent migraine/headache history, history of acute and prophylactic headache medications within the past 30 days, and history of other recent/concomitant medications. 5. Obtain date of last menstrual cycle and perform urine pregnancy test, if appropriate. Results of the pregnancy test must be negative to continue in study. 6. Perform physical and neurological examinations. 7. Measure vital signs (height, weight, resting heart rate, and blood pressure). 8. Review Baseline Headache Diary. Subjects will be instructed to complete a daily online headache diary. Assessments to be captured are start/stop time, severity, associated symptoms, use of rescue medications, and unusual symptoms. 9. Administer Columbia-Suicide Severity Rating Scale (C-SSRS). 10. Schedule Visit 2. VISIT 2 - RANDOMIZATION 1. Verify Inclusion/Exclusion Criteria. Subjects must continue to meet all inclusion (including ≥ 3 days of migraine during baseline) and none of the exclusion criteria. 2. Perform urine pregnancy test, if appropriate. Results of the pregnancy test must be negative to continue in study. 3. Measure vital signs (weight, resting heart rate, and blood pressure). 4. Record any changes to concomitant medications. 5. Record any Serious Adverse Events (SAE) since signing the Informed Consent. 6. Review Baseline Headache Diary for completeness and continuing eligibility. 7. Randomize subject 8.
