A Study to Assess the Safety, Tolerability, and Effects of MK-0974 (Telcagepant) on Exercise Tolerance in Patients With Stable Angina (MK-0974-014)

- Coronary Heart DiseaseCalcitonin Gene-related Peptide ReceptorAngina Pectoris
- Interventions
- Registration Number
- NCT01294709
- Lead Sponsor
- Merck Sharp & Dohme LLC
- 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.
- Detailed Description
Amendment 3 of the protocol reduced the dose of telcagepant to be administered from a single dose of 900 mg to a single dose of 600 mg. Pooled data from both the 600-mg and the 900-mg group wiil be utilized in the analyses. Also due to supply issues regarding the 300 mg telcagepant capsules, 280 mg telcagepant tablets with demonstrated bioequivalence to the 300 mg telcagepant capsules, could be administered to participants enrolled after the implementation of Amendment 3.

Group Intervention Description Telcagepant/ Placebo telcagepant 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. Placebo/Telcagepant telcagepant Participants receive single oral dose of two capsules or tablets of placebo for telcagepant (or three capsules of placebo for telcagepant) in Period 1 and a 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 2 of the crossover. Each treatment period is separated by a washout of 96-240 hours. Telcagepant/ Placebo Placebo to telcagepant 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. Placebo/Telcagepant Placebo to telcagepant Participants receive single oral dose of two capsules or tablets of placebo for telcagepant (or three capsules of placebo for telcagepant) in Period 1 and a 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 2 of the crossover. Each treatment period is separated by a washout of 96-240 hours.
- Primary Outcome Measures
Name Time Method Number of Participants With Laboratory Adverse Events Up to 10 days post dose in Period 1 and up to 14 days post dose in Period 2 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.
Number of Participants With Clinical Adverse Events (AEs) Up to 10 days post dose in Period 1 and up to 14 days post dose in Period 2 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.
Total Exercise Duration on the Treadmill Test 2.5 to approximately 2.75 hours post dose of each treatment period 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
- Secondary Outcome Measures
Name Time Method ST Segment Depression at Peak Exercise 2.5 to approximately 2.75 hours post dose of each treatment period 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 ECG, symptoms, and arm blood pressure were continuously monitored. The time of peak exercise was considered the time at which the participant reached at least one of the criteria for stopping the treadmill test (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). The ECG for that timepoint (time of peak exercise) was evaluated and the amount of ST segment depression was determined.
Time to 1 mm ST Segment Depression 2.5 to approximately 2.75 hours post dose of each treatment period 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 ECG, symptoms, and arm blood pressure were continuously monitored. The ECG was reviewed and the time to the first ST segment depression of 1 mm was recorded.
