The Efficacy and Tolerability of NP101 Patch in the Treatment of Acute Migraine

Subjects stayed in the study until they had treated one migraine headache with a study patch
or two months after randomization, whichever occurred first. During a migraine headache,
subjects rated their baseline headache pain severity in a Migraine Study Diary using a
4-point scale (0 = none, 1 = mild, 2 = moderate, 3 = severe) and applied the study patch
only if their score was 2 or 3 (i.e., qualifying migraine headache). In addition to headache
pain severity, subjects also recorded the presence or absence of aura, nausea, phonophobia,
and photophobia, as well as the location of their headache (unilateral or bilateral) and
whether their headache increased with movement.
