Trial Outcomes & Findings for A Study to Evaluate the Effects of Ezetimibe (MK-0653) on the Postprandial (Following a Meal) Lipoprotein Response in Participants With Primary Hypercholesterolemia (High Cholesterol) (MK-0653-072)(COMPLETED) (NCT NCT00101439)

NCT ID: NCT00101439

Last Updated: 2024-06-18

Results Overview

On each of 2 days prior to the last day of each treatment period, participants consumed 2 large eggs in the evening. On the morning of the final day of each treatment period, fasting participants were given a site-prepared, cholesterol-enriched milkshake that provided 1114 calories of total energy (\~44% of calories from fat, \~40% of calories from carbohydrate and \~17% of calories from protein) and 504 mg of cholesterol. The milkshake was consumed over a 15-minute period. Plasma samples were collected immediately prior to consumption of the test meal (baseline) and at 2, 3, 4, and 6 hours afterwards for isolation and analysis of lipoprotein fractions. The geometric mean concentration level was calculated using data obtained at all timepoints.

PRIMARY outcome

Timeframe: Immediately prior to consumption of the test meal (baseline) and at 2, 3, 4, and 6 hours after test meal on Day 28 of each treatment period.

Population: Participants who received at least one dose of study drug and did not have any protocol violations.

On each of 2 days prior to the last day of each treatment period, participants consumed 2 large eggs in the evening. On the morning of the final day of each treatment period, fasting participants were given a site-prepared, cholesterol-enriched milkshake that provided 1114 calories of total energy (\~44% of calories from fat, \~40% of calories from carbohydrate and \~17% of calories from protein) and 504 mg of cholesterol. The milkshake was consumed over a 15-minute period. Plasma samples were collected immediately prior to consumption of the test meal (baseline) and at 2, 3, 4, and 6 hours afterwards for isolation and analysis of lipoprotein fractions. The geometric mean concentration level was calculated using data obtained at all timepoints.

SECONDARY outcome

Timeframe: Immediately prior to consumption of the test meal (baseline) and at 2, 3, 4, and 6 hours after test meal on Day 28 of each treatment period.

Population: Participants who received at least one dose of study drug and did not have any protocol violations.

The milkshake was consumed over a 15-minute period. Plasma samples were collected immediately prior to consumption of the test meal (baseline) and at 2, 3, 4, and 6 hours afterwards for isolation and analysis of lipoprotein subfractions. The geometric mean concentration level was calculated using data obtained at all timepoints.
