157This 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.
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.

Comparison of the mean change from baseline in the frequency of migraine headache days per 28-day period ending with the cessation of treatment period month 3 in subjects treated with MLD10 versus placebo. A migraine headache day will be defined as a calendar day (00:00 to 23:59) with 4 or more hours of migraine headache, fulfilling International Classification of Headache Disorders-3beta criteria, and/or any headache of any duration with the use of migraine-specific acute medications(s) (i.e. ergot alkaloids, ergot combinations, opioids, triptans, combination analgesics [simple analgesics combined with opioids or barbiturate with or without caffeine]).
Comparison of the change from baseline of subjects treated with MLD10 versus placebo in the frequency of headache days during the 3 month treatment period. A headache day will be defined as any day not classified as a migraine day, but recorded headache of any severity and/or duration.
Change from baseline (28 day period) in the total cumulative minutes of headache during each 28-day treatment period month 1, 2, & 3 in subjects treated with MLD10 versus placebo. All headaches and/or migraines will be including in this outcome analysis.
Change from baseline (28 day period) in the average pain severity at time of onset compared to each 28-day treatment period month 1, 2, & 3 in subjects treated with MLD10 versus placebo. Headache pain severity was measured on a scale 1 = Mild, 2 = Moderate, 3 = Severe.
Change from baseline (28 day period) in the total number of acute headache pain medications used during each 28 day treatment period month 1, 2, & 3 in subjects treated with MLD10 versus placebo.
Change from Visit 2 to Visit 5 in the total MIDAS score in subjects treated with MLD10 versus placebo. The MIDAS test determines how severely migraines affect daily functioning. The responses of a variety of questions will be scored according to the questionnaire's scoring guide. A total score will be calculated ranging from 0-93. A score of 0-5 indicates little or no disability, 6-10 mild disability, 11-20, moderate disability, 21+ severe disability.
Comparison of SGIC at Visit 5 in subjects treated with MLD10 versus placebo. Global impression of change rated by the subject will be assessed using a 7-point Likert scale ranging from -3 to 3 with -3 = very much worse, -2 = much worse, -1 = minimally worse, 0 = no change, 1 = minimally improved, 2 = much improved, 3 = very much improved.
Comparison of PGIC at Visit 5 in subjects treated with MLD10 versus placebo. The PGIC will be an impression of change rated by the investigator using a 7-point Likert scale ranging from -3 to 3 with -3 = very much worse, -2 = much worse, -1 = minimally worse, 0 = no change, 1 = minimally improved, 2 = much improved, 3 = very much improved.
