Trial Outcomes & Findings for Multiple Attacks Study to Compare the Efficacy and Safety of MK-0974 With Placebo for Acute Migraine (MK-0974-031) (NCT NCT00483704)
NCT ID: NCT00483704
Last Updated: 2018-10-18
Results Overview
Pain Freedom (PF) at 2 hours post-dose (first migraine attack), with pain freedom defined as a reduction in headache severity from Grade 3/2 at baseline to Grade 0 at 2 hours post-dose. Headache severity was subjectively rated by the participant at predefined time points on a scale of Grade 0 to Grade 3: Grade 0 - No pain; Grade 1 - Mild pain; Grade 2 - Moderate Pain; and Grade 3 - Severe Pain.

Telcagepant 140 mg
Telcagepant 140 mg, oral, across 4 migraine attacks. For migraine attack 1 only, if no headache relief is obtained after 2 hours post dose, or if the migraine recurs after 2 hours of the initial treatment, participants may receive an optional second dose of telcagepant 140 mg or placebo.

Telcagepant 280 mg
Telcagepant 280 mg, oral, across 4 migraine attacks. For migraine attack 1 only, if no headache relief is obtained after 2 hours post dose, or if the migraine recurs after 2 hours of the initial treatment, participants may receive an optional second dose of telcagepant 280 mg or placebo.

Placebo
The placebo group is comprised of Control Group 1 and Control Group 2. Control Group 1 receives placebo across 3 migraine attacks (1st, 2nd, and 4th) and telcagepant 140 mg for the 3rd migraine attack. Control Group 2 receives placebo across 3 migraine attacks (1st, 2nd, and 3rd) and telcagepant 140 mg for the 4th migraine attack. For both groups for migraine attacks 2, 3, and 4, no study medication will be provided as an optional second dose.

PRIMARY outcome
Timeframe: 2 hours post-dose for the first migraine attack (up to 6 months)Population: The full-analysis set (FAS) included participants treated that migraine attack, and had both a baseline value and at least 1 post-dose efficacy measurement for pain severity prior to, or including, the 2-hour time point. Participants were excluded from this analysis who did not have a baseline pain score or post-dose data through 2 hours.
Pain Freedom (PF) at 2 hours post-dose (first migraine attack), with pain freedom defined as a reduction in headache severity from Grade 3/2 at baseline to Grade 0 at 2 hours post-dose. Headache severity was subjectively rated by the participant at predefined time points on a scale of Grade 0 to Grade 3: Grade 0 - No pain; Grade 1 - Mild pain; Grade 2 - Moderate Pain; and Grade 3 - Severe Pain.

Note that for the control groups, a positive PF response arising from the administration of the 1 talcagepant treated migraine attack will count as one of the 3 positive PF responses needed to fulfill the criteria for PFC.
