Study to Evaluate the Safety, Tolerability, and Blood Pressure Effect of an Oral Dose of Sumatriptan Alone and in Combination With MK-0974 (Telcagepant) in Migraine Patients (0974-026)

Time-weighted Mean Arterial Pressure (Telcagepant Versus Placebo)

In each treatment period (1 through 4), duplicate readings of semi-recumbent blood pressure (BP) were completed using an automated blood pressure machine at predose, 30, 60, 90, 120, 150, 180, and 360 minutes postdose. Mean arterial pressure (MAP) was calculated as follows: MAP = Diastolic Blood Pressure (DBP) + (0.33 \* Pulse Pressure \[PP\]) where PP = Systolic Blood Pressure \[SBP\] minus DBP. Only mean arterial pressure measurements up to and including 150 minutes postdose (including the predose measurement) were used to calculate the time-weighted averages. Time-weighted averages for each participant were obtained by calculating the area under the measurement-time curve of mean arterial pressure divided by the time period over which measurements were made (i.e. 150 minutes).

Time frame: Predose up to 150 minutes postdose of each treatment period (up to 10 weeks)

Number of Participants Who Experienced an Adverse Event During the Study

Participants were assessed throughout the study for adverse events. An adverse event was defined as any unfavorable and unintended change in the structure, function, or chemistry of the body temporally associated with the use of the 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 was temporally associated with the use of the product, was also an adverse event.

Time frame: up to 14 days after last dose of study drug (up to 10 weeks)

Number of Participants Who Were Discontinued From Any Study Period Due to an Adverse Event

Participants were assessed throughout the study for adverse events. An adverse event was defined as any unfavorable and unintended change in the structure, function, or chemistry of the body temporally associated with the use of the 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 was temporally associated with the use of the product, was also an adverse event. The number of participants who were discontinued from the study due to adverse event was summarized.

Time frame: up to 10 weeks
