Enrollment: 173
Healthy volunteers: no

Brief summary:
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). \[Study 1 of 2\]

Detailed description:
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).

Arms:
arm 1: Combination product (sumatriptan and naproxen sodium) \[Attack 1\] followed by placebo \[Attack 2\] arm 2: Placebo \[Attack 1\] followed by Combination Product (sumatriptan and naproxen sodium) \[Attack 2\]

Interventions: intervention 1: Combination Product (sumatriptan succinate / naproxen sodium) intervention 2: Placebo
Intervention descriptions: intervention 1: Bilayer tablet containing 85mg sumatriptan (as 119mg sumatriptan succinate; fast disintegrating/rapid release formulation) active ingredient in one layer, and 500mg naproxen sodium active ingredient in the second layer. intervention 2: Matching placebo tablet.
