Condition atherosclerosis
Treatment niaspan
Sponsor University of Oxford

Start date September 2004
End date February 2009
Trial size 70 participants
Trial identifier NCT00232531, 04.OXA.020


AIM 1 will test the hypothesis that elevation of high-density lipoprotein (HDL) through treatment with Niaspan will accelerate the regression of atherosclerotic plaque in patients with established atherosclerosis. The investigators will therefore study patients with atherosclerosis in the aorta and carotid artery. Plaque quantification will be with magnetic resonance imaging (MRI).

AIM 2 will assess the ability of Niaspan to improve endothelial function in patients with coronary artery disease and type II diabetes mellitus, who typically have low high-density lipoprotein cholesterol (HDL-C), and high risk of cardiovascular events.

Eligibility Criteria

Male or female participants at least 18 years old.

Inclusion Criteria: - Aim 1: Carotid or peripheral arterial disease and HDL <1mmol/L - Aim 2: Coronary artery disease, type II diabetes and HDL <1mmol/L Exclusion Criteria: The following will constitute exclusion criteria: - Inability to provide informed consent, - Known intolerance of a study drug, - Use of niacin or a fibrate at time of screening, - AST or ALT elevated above normal range at time of screening - Use of oral nitrates or nicorandil - Uncontrolled or newly diagnosed diabetes mellitus - Symptomatic heart failure or heart failure requiring treatment with diuretics - Fasting triglycerides > 500mg/dL [5.65mmol/L] - Patients with acute coronary syndromes, active peptic ulcer disease, - Active gout, - Standard exclusions for MRI will apply, i.e. pacemakers, implantable defibrillators, metal implants or embedded metallic fragments of any kind.

Principal investigator Robin P Choudhury, DM, MRCP
Description Patients will be randomised to receive either Niaspan 2000mg each night or placebo. Niaspan will be commenced at 375mg daily and increased to 500mg then to 750, and 1000mg daily at weekly intervals. After 4 weeks the dose will be increased to 1500mg daily and, after a further one month, the study dose of 2000mg daily2 will be instigated. Immediately before randomization (to exclude patients unable to tolerate MRI because of claustrophobia), and 6 and 12 months after commencing treatment participants will undergo MR examination.
