Brief summary
This study is being conducted to evaluate the hypothesis that use of Treximet in patients with chronic migraine, when used on a short term daily basis and as rescue for break through attacks, will reduce migraine frequency and impact.
Detailed description
One investigative center will enroll 40 subjects in the US. At Visit 1, following informed consent, a medical, migraine, and medication history will be collected and a physical and neurological exam with vital signs will be performed. A 12-lead ECG will be completed. Eligible subjects will complete a 1-month Baseline Period and treat migraine with their current preferred treatment of choice. Throughout the study, subjects will complete daily Headache Diaries reporting headache severity and associated symptoms with use of study medication in each 30-day period. At Visit 2, subjects continuing to meet eligibility criteria will be randomized 1:1 to Treximet or naproxen and provided with medication to treat daily for 30 days. At Visits 3 and 4 subjects will be provided with study medication to treat on 14 or fewer days per month. Subjects will be encouraged to treat their migraine attacks within 1 hour of onset of headache pain and while the pain is still mild. Adverse events will be collected beginning from the first dose of study medication. Subjects exit the study at Visit 5 after a 3-month Treatment Period. The study provides opportunity to evaluate the usefulness of patient education with a 15-minute digital versatile disc (DVD) concerning the processes of headache evolution and lifestyle changes for better headache management. At Visit 2, subjects will view the DVD in-clinic with a copy provided for at-home viewing. Subjects will complete a Lifestyle Choices for Better Migraine Management Questionnaire at each visit and receive 3 copies to be completed weekly and returned at the following visit. The Migraine Disability Assessment questionnaire (MIDAS) will be completed at Visits 2 and 5 to determine the level of pain and disability caused by headache.

Study medication is to be administered 1 tablet per day x 30 days in Treatment Period Month 1. Study medication may be administered on up to 14 days per month in Treatment Period Months 2 and 3.
DRUGNaproxen Sodium
Each tablet of Naproxen Sodium for oral administration is provided in 500mg tablet. Study medication is to be administered 1 tablet per day x 30 days in Treatment Period Month 1. Study medication may be administered on up to 14 days per month in Treatment Period Months 2 and 3.

Recruitment details
Recruitment period was from date of Institutional Review Board (IRB) approval (8-3-10) until date last patient enrolled (1-30-12). Subjects were recruited from general population at two clinical research centers.
Pre-assignment details
Subjects completed a 30 day Baseline period between Visit 1 and Visit 2 before Randomization. Subjects must have had 15 or more headache days during the 30 day Baseline period in order to be randomized into the study Treatment periods. Fifty-six subjects were screened for study, however only 28 subjects randomized for treatment due to screen fail.
