Last verified: January 2014
  Purpose

The primary aim is to assess the effects of raising HDL cholesterol (the good type) with extended release niacin/laropiprant 2g (previously known as MK−0524A) versus matching placebo on the risk of heart attack or coronary death, stroke, or the need for arterial bypass procedures (revascularisation) in people with a history of circulatory problems. The secondary aim is to assess the effects of extended release niacin/laropiprant 2g daily on heart attack, coronary death, stroke, and revascularisation separately and to assess the effects on mortality both overall and in various categories of causes of death, and of the effects on major cardiovascular events in people with a history of different diseases at the beginning of the study.

Detailed Description:

Cardiovascular disease is one of the leading causes of morbidity and mortality in the United Kingdom (UK), as well as in the developed and the developing world. Finding new and safe treatments to reduce the burden of heart disease and strokes is therefore an important contribution to public health and in the wider public interest. HPS2-THRIVE aims to find out whether by combining niacin (a drug that has been available for 50 years) with a new drug laropiprant(which reduces the side-effects of niacin) is beneficial. All participants in HPS2-THRIVE will have established cardiovascular disease and therefore be at very high risk of recurrent vascular events (myocardial infarction, stroke or the need for arterial revascularisation). Two of the most important risk factors for recurrent events in such patients are the blood levels of LDL cholesterol with a positive association, and HDL cholesterol levels with a negative association.

HDL cholesterol has long been known to have a strong inverse correlation with coronary heart disease (CHD) risk. But, randomized trial evidence for beneficial effects from raising HDL cholesterol is limited. One of the most effective HDL-raising agents is niacin but the tolerability of niacin has been severely limited by flushing and cutaneous side-effects, which appear to be mediated largely by prostaglandin D. Laropiprant is a selective prostaglandin D receptor antagonist that substantially reduces the frequency and intensity of niacin-induced flushing. Daily oral doses of extended release (ER) niacin plus Laropiprant 2g(formerly MK-0524A) have been well tolerated in early studies and increase HDL cholesterol by 20-25%. The trial will assess whether this increase in HDL cholesterol translates into clinical benefit as is expected from the observational evidence. In addition, all participants will also be provided with effective LDL-lowering therapy, as either simvastatin 40mg daily alone or with ezetimibe 10mg daily in a combination tablet.

The complementary effects on the HDL (good) and LDL (bad) cholesterol produced by extended release niacin/laropiprant 2 g daily and simvastatin 40 mg with or without ezetimibe 10 mg should provide an excellent treatment option for patients with vascular disease. However, no trials so far have demonstrated clearly that raising HDL cholesterol produces the expected reduction in cardiovascular risk. If HPS2-THRIVE is able to demonstrate reliably that raising HDL cholesterol reduces the risk of further cardiovascular events then this will be relevant to hundreds of millions of people worldwide.

  • Previous significant adverse reaction to a statin, ezetimibe, niacin or laropiprant;
  • Active peptic ulcer disease;

  • verapamil
  • danazol (Note: Patients who are temporarily taking such drugs may be re-screened when they discontinue them, if considered appropriate.);
  • Known to be poorly compliant with clinic visits or prescribed medication;
