NCT01294709

Brief Summary

This study will assess the safety of telcagepant in coronary artery disease (CAD) participants with stable angina during exercise treadmill testing and evaluate whether calcitonin gene-related peptide (CGRP) receptor antagonism by telcagepant reduces exercise tolerance in these participants. Primary hypothesis is that telcagepant does not significantly decrease exercise duration compared to placebo, as measured by a treadmill exercise test; that is, the true treatment difference in exercise duration (MK-0974 - Placebo) \>= -60 seconds.

Outcome Measures

Primary Outcomes (3)

  • Number of Participants With Clinical Adverse Events (AEs)

    An AE 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 AE. A clinical AE was an AE reported as a result of a clinical examination or reported by the participant.

    Up to 10 days post dose in Period 1 and up to 14 days post dose in Period 2

  • Number of Participants With Laboratory Adverse Events

    An AE 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 AE. A laboratory AE was an AE reported as a result of a laboratory assessment or test.

    Up to 10 days post dose in Period 1 and up to 14 days post dose in Period 2

  • Total Exercise Duration on the Treadmill Test

    Bruce (and Modified Bruce) Protocol was used to assess the exercise duration on a treadmill. This protocol consists of a standardized gradual incremental increase in external workload every 3 minutes while the participant's electrocardiogram (ECG), symptoms, and arm blood pressure were continuously monitored. Regardless of whether the participant believed he or she could continue, the test was discontinued upon evidence of chest discomfort, severe shortness of breath, dizziness, fatigue, ST-segment depression of greater than 2 mm, a fall in systolic blood pressure exceeding 10 mmHg, or the development of a ventricular tachyarrhythmia

    2.5 to approximately 2.75 hours post dose of each treatment period

Secondary Outcomes (2)

  • ST Segment Depression at Peak Exercise

    2.5 to approximately 2.75 hours post dose of each treatment period

  • Time to 1 mm ST Segment Depression

    2.5 to approximately 2.75 hours post dose of each treatment period

Study Arms (2)

Telcagepant/ Placebo

EXPERIMENTAL

Participants receive single oral dose of 600 mg (two 300 mg capsules or two bioequivalent 280 mg tablets) or 900 mg telcagepant (three 300 mg capsules) in Period 1 and single oral dose of two capsules or tablets of placebo for telcagepant (or three capsules of placebo for telcagepant) in Period 2 of the crossover. Each treatment period is separated by a washout of 96-240 hours.

EXPERIMENTAL

Eligibility Criteria

Age18 Years - 85 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Participant has clinically documented stable coronary artery disease as demonstrated by coronary angiography, echocardiogram, or stress test, etc., or participant is on stable doses of current medication for the treatment of coronary artery disease for a minimum of 30 days.
  • Participant has a history of stable angina (chronic stable angina pectoris that is triggered by physical effort and relieved by rest and/or sublingual nitroglycerin) for at least 3 months prior to study start, with no intervening symptoms of unstable angina.
  • Participant is able to demonstrate reproducibly positive exercise tests by completing treadmill tests on 2 separate days, within 1-8 days.
  • Participant agrees to refrain from drinking alcohol from 24 hours prior to study drug administration, on study procedure days, and until release from the study facility.
  • Participants agrees to refrain from smoking from midnight before study procedures until study procedures are complete for the day.
  • Participant has no clinically significant abnormality on screening laboratory safety assessment.
  • Participant agrees to refrain from unaccustomed strenuous physical activity from the prestudy (screening) visit, throughout the study, and until the post-study visit.

You may not qualify if:

  • Participant is pregnant (positive serum beta-human chorionic gonadotropin \[β-hCG\] test at prestudy), breast-feeding, or is a female expecting to conceive within the projected duration of the study.
