Telcagepant for Prevention of Menstrually Related Migraine in Female Participants With Episodic Migraine (MK-0974-065)

Merck Sharp & Dohme LLC4,548 enrolled

Overview

This is a multicenter study to test the hypothesis that telcagepant is superior to placebo in preventing perimenstrual migraines as measured by mean monthly headaches during the entire treatment period. This study will also evaluate the safety and tolerability of telcagepant for female migraine participants.

Outcomes

Primary Outcomes

Number of Participants With Clinical Adverse Events (AEs)

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 drug, whether or not considered related to the use of the study drug. 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 drug, is also an AE. A clinical AE is an AE reported as a result of a clinical examination or reported by the participant.

Time frame: Up to 14 days after the last dose of study drug (Up to 6.5 months)

Number of Participants Who Discontinued Study Due to a Clinical AE

Time frame: Up to 6 months

Number of Participants With Laboratory AEs

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 drug, whether or not considered related to the use of the study drug. 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 drug, is also an AE. A laboratory AE is an AE reported as a result of a laboratory assessment or test.

Time frame: Up to 6 months

Number of Participants Who Discontinued Study Due to a Laboratory AE

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 drug, whether or not considered related to the use of the study drug. 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 drug, is also an AE. A laboratory AE is an AE reported as a result of a laboratory assessment or test.

Mean Monthly Headache Days During Entire Study Period Among Participants With Menstrually-related Migraine (MRM) or Pure Menstrual Migraine (PMM) Who Have an Average of 5 or More Moderate or Severe Migraine Headaches Per Month at Baseline

Participants completed a headache diary each evening at bedtime, including recording headache duration and acute headache medication use. Mean monthly headache days was calculated from diary data. A headache day was defined as a day in which a headache (defined as headache pain ≥30 minute duration or requiring acute treatment) started, ended, or recurred. Headache pain persisting for more than 1 calendar day after initial onset was considered an occurrence of additional headache days. Mean monthly rate was adjusted to 28 days. Participant subgroups (based on symptoms over the 3 menstrual cycles prior to study): PMM - In ≥2 out of 3 cycles attacks occur exclusively on Day 1 ± 2 of menstruation and at no other times of the cycle; MRM - In ≥2 out of 3 cycles attacks occur on Day 1 ± 2 of menstruation and additionally at other times of the cycle.

Time frame: Up to 6 months

Mean Monthly On-drug Headache Days During the Entire Study Period Among Participants With MRM or PMM Who Have an Average of 5 or More Moderate or Severe Migraine Headaches Per Month at Baseline

Participants completed a headache diary each evening at bedtime, including recording headache duration and acute headache medication use. Mean monthly on-drug headache days was calculated from diary data. "On-drug" headache day was a day, which had a valid diary entry and which followed a study drug dosing day, in which a headache (defined as headache pain ≥30 minute duration or requiring acute treatment) started, ended, or recurred. Headache pain persisting for more than 1 calendar day after initial onset into additional qualifying days (i.e., day following dosing day) was considered an occurrence of additional headache days. Mean monthly rate was adjusted to 7 days. Participant subgroups (based on symptoms over the 3 menstrual cycles prior to study): PMM - In ≥2 out of 3 cycles attacks occur exclusively on Day 1 ± 2 of menstruation and at no other times of the cycle; MRM - In ≥2 out of 3 cycles attacks occur on Day 1 ± 2 of menstruation and additionally at other times of the cycle.
