NCT ID: NCT01414166 Terminated - Dyslipidemia Clinical Trials

Niacin/Laropiprant Tablet for South and Southeast Asians With Low High-Density Lipoprotein Cholesterol (LDL-C) at Risk for Cardiovascular Disease (MK-0524A-108)

Start date: September 2011
Phase: Phase 3
Study type: Interventional

The study will evaluate the use of extended release niacin/laropiprant (ERN/LRPT) combination tablets in a primary prevention population currently not taking or eligible for lipid-modifying therapy (LMT); the population will comprise participants with low to moderate risk for coronary heart disease (CHD), low high density lipoprotein cholesterol (HDL-C), low density lipoprotein cholesterol (LDL-C) at or below goal level, and normal or mildly elevated triglyceride (TG) levels.

NCT ID: NCT01335997 Terminated - Clinical trials for Primary Hypercholesterolemia

Efficacy and Safety of Extended-Release Niacin/ Laropiprant/Simvastatin Tablets in Participants With Hypercholesterolemia or Mixed Dyslipidemia (MK-0524B-143)

Start date: May 1, 2011
Phase: Phase 3
Study type: Interventional

This study is being done to find out if tablets containing extended release (ER) niacin, laropiprant, and simvastatin (ERN/LRPT/SIM) are as effective as tablets containing ER niacin and laropiprant taken with simvastatin tablets (ERN/LRPT + SIM) for lowering high cholesterol and high lipid levels in the blood. The primary hypothesis is that ERN/LRPT/SIM 2 g /20 mg is equivalent to ERN/LRPT 2 g coadministered with simvastatin 20 mg in reducing low-density lipoprotein cholestrol (LDL-C).

NCT ID: NCT01308203 Terminated - Clinical trials for Coronary Artery Disease

Lipid Efficacy of the Extended Release Niacin/Laropiprant Combination in Patients With Cardiovascular Disease

Start date: October 2011
Phase: Phase 4
Study type: Interventional

- Clinical studies with statins have shown that patients that suffered a cardiovascular event have a high residual risk. Residual risk decreases with the attaining of progressive lower LDL-C levels. - In patients treated with statins, HDL-C level is an independent inverse predictor of subsequent CV and coronary plaque progression, even when LDL-C levels are less than 70 mg/dL. - Therefore the purpose on this study is to assess the lipid efficacy on lipid profile and effects on HDL-C metabolism and function of the extended release niacin/laropiprant combination added to usual therapy in very high risk patients with cardiovascular disease and low HDL-C that did not achieve the optional very low LDL-C or non-HDL-C goals

NCT ID: NCT01294683 Terminated - Dyslipidemia Clinical Trials

A Study to Evaluate Efficacy and Safety of Extended-Release Niacin + Laropiprant + Simvastatin in Participants With Primary Hypercholesterolemia or Mixed Dyslipidemia (MK-0524B-118)

Start date: February 4, 2011
Phase: Phase 3
Study type: Interventional

This study is being done to find out if tablets containing extended release (ER) niacin, laropiprant, and simvastatin (ERN/LRPT/SIM) are as effective as tablets containing ER niacin and laropiprant taken with simvastatin tablets (ERN/LRPT + SIM) for lowering high cholesterol and high lipid levels in the blood. The primary hypothesis is that ERN/LRPT/SIM 2 g/40 mg is equivalent to ERN/LRPT 2 g co-administered with simvastatin 40 mg in reducing low-density lipoprotein cholesterol (LDL-C).

NCT ID: NCT01274559 Terminated - Clinical trials for Primary Hypercholesterolemia

Efficacy and Safety of Extended Release (ER) Niacin/Laropiprant When Added to Ongoing Lipid-Modifying Therapy in Patients With High Cholesterol or Abnormal Lipid Levels (MK-0524A-133)

Start date: March 1, 2011
Phase: Phase 3
Study type: Interventional

This is a multicenter, randomized, double-blind, placebo-controlled study in participants with primary hypercholesterolemia or mixed dyslipidemia, and elevated low density lipoprotein-cholesterol (LDL-C) to assess the efficacy and safety of extended release (ER) niacin/laropiprant [ERN/LRPT (MK-0524A)] when added to the following ongoing lipid-modifying therapy (LMT): simvastatin, atorvastatin, rosuvastatin monotherapy, ezetimibe/simvastatin fixed dose combination (FDC), or any statin co-administered with ezetimibe. The study is based on the hypothesis that ERN/LRPT 2 g daily will be superior to placebo at lowering LDL-C at Week 12 of treatment.

NCT ID: NCT01228019 Terminated - Clinical trials for Hypercholesterolemia

Niacin (+) Laropiprant (TREDAPTIVE) Re-examination Study (MK-0524A-119)

Start date: December 2010
Phase: N/A
Study type: Observational

This survey is being conducted to assess the safety and efficacy of niacin (+) laropiprant (TREDAPTIVE) in usual practice in Korea according to the new product re-examination regulations of the Korean Food and Drug Administration.

NCT ID: NCT01052311 Terminated - Clinical trials for Coronary Artery Disease

The Impact of Tredaptive on Flow-Mediated Dilation in Cardiac Patients

Start date: July 2010
Phase: Phase 4
Study type: Interventional

Laropiprant (LRP; Merck & Co., Inc, Whitehouse Station, NJ, USA) is a potent, once-daily, highly selective PGD2-receptor (DP1) antagonist. A combination tablet containing 1 g of extended-release niacin and 20 mg of laropiprant (ERN/LRPT) offers improved tolerability, supporting a simplified 1-2 g dosing paradigm and improved adherence. Statins and niacin improve endothelial function in cardiac patients, however, there is no data yet regarding the additive effects of raising HDL-C by ERN/LRPT and statins on endothelial function in cardiac patients. Thus the aim of the present study is to evaluate the impact of 3 months' administration of ERN/LRPT compared to placebo added to statins on endothelial function, assessed by brachial artery vasoreactivity in stable cardiac patients.

NCT ID: NCT01025492 Terminated - Dyslipidemia Clinical Trials

Study of Trilipix Effects on Lipids and Arteries

Start date: November 2009
Phase: Phase 4
Study type: Interventional

The investigators will study the effects of the addition of Trilipix (fenofibric acid) versus placebo to ongoing statin treatment on high density lipoprotein (HDL) composition and arterial function.
