Measure
Telcagepant 280 mg/300 mg
Participants receive telcagepant 300 mg soft gel capsules or telcagepant 280 mg tablets, administered orally as a single dose at onset of migraine. If still experiencing a migraine 2 hours after the first dose of telcagepant, participants may take an optional second dose of study drug or non-study rescue medication. Participants may take up to 16 doses (for treatment of up to 8 migraines) of telcagepant per month for up to 18 months.
Rizatriptan 10 mg
Participants receive rizatriptan tablets, administered orally as a single dose at onset of migraine. If still experiencing a migraine 2 hours after the first dose of rizatriptan, participants may take an optional second dose of study drug or non-study rescue medication. Participants may take up to 16 doses (for treatment of up to 8 migraines) of rizatriptan per month for up to 18 months.

Population: The APAT population consisted of all participants who received at least one dose of study drug.

An AE is defined as any unfavorable and unintended change in the structure, function, or chemistry of the body temporally associated with the use of the study product, whether or not considered related to the use of the product. Any worsening (i.e., any clinically significant adverse change in frequency and/or intensity) of a preexisting condition which is temporally associated with the use of the study product, is also an AE. A clinical AE was an AE reported as a result of a clinical examination. Participants were monitored for clinical AEs for 14 days after any dose of study drug.

SECONDARY outcome

Timeframe: 2 hours post-dose (Up to 18 months)

Population: The Full Analysis Set (FAS) population consisted of all participants who were randomized and reported at least one treated migraine attack with at least one post-treatment efficacy evaluation.

Participants were asked to rate their migraine headache severity with ratings of 0=No pain, 1=Mild pain, 2=Moderate pain, and 3=Severe pain. PF at 2 hours post-dose is defined as a decrease from mild, moderate or severe migraine headache (Grade 1, 2, or 3) at baseline to no pain (Grade 0) 2 hours post-dose.
