A Study of Combination Product (Sumatriptan Succinate and Naproxen Sodium) in Migraine Subjects Who Report Poor Response or Intolerance to Short Acting Triptans (Study 1 of 2)

This is a randomized, double-blind, placebo-controlled, crossover, two-attack, out-patient, early-intervention evaluation of subjects who have migraine with or without aura and who discontinued use of short acting triptan(s) within the past year due to non-response or intolerance. Subjects will treat 2 separate migraine attacks during the mild phase of each attack; one attack will be treated with one tablet of the Combination Product (sumatriptan succinate and naproxen sodium) and the other attack with one tablet of placebo (crossover design); however, the order of these treatments will be randomized. A minimum 1-week washout period is required between study medication treatment of the first and second migraine attacks. Each subject will have two visits: (1) a Screening visit at study entry and (2) a Final visit 4-10 days after the second (or last) attack. A telephone contact will also be required 1-3 days after the first attack, and then once per month until the Final visit. The primary study objective is to assess efficacy as measured by sustained pain-free (SPF) relief of Combination Product compared to placebo in treating migraine subjects who have previously discontinued treatment with short acting triptans (rizatriptan, sumatriptan, almotriptan, zolmitriptan, and eletriptan).
