Effect of Niaspan on Cholesterol in Men
Effect of Niaspan on Parameters of Reverse Cholesterol Transport and HDL-C Subclasses in Male Subjects With Low HDL-C Levels

To determine whether 8 weeks of Niaspan treatment increases cholesterol efflux in male subjects with low HDL-C cholesterol when compared to no treatment.

To determine whether 8 weeks of Niaspan treatment increases fecal cholesterol excretion when compared to no treatment.

To determine whether 8 weeks of Niaspan treatment increases the rate of global reverse cholesterol transport when compared to no treatment.

This will be a single center, open-label, randomized, mechanism of action study consisting of 8 weeks of active treatment preceded by a screening phase from one to 8 weeks and a baseline measurement of parameters of reverse cholesterol transport for 10 days. The population for this trial is 15 non-diabetic men aged 18-70 years. Ten subjects will be low HDL-C male volunteers who will receive aspirin and Niaspan and five subjects will be low HDL-C male volunteers who will receive only aspirin.

  • BMI 18.5-40 kg/m2
  • HDL-C values <40 mg/dL
  • Triglyceride value 150-500 mg/dL.
  • Good health based on medical history, physical examination and laboratory safety tests performed at the screening visit or prior to initial dose of study medication.

  • Avoidance of extreme change of physical activity from screening through the follow-up period.

Exclusion Criteria:

Subjects are excluded from participation in the study if any of the following criteria apply:

  • History of intolerance to Niacin or Niaspan.

  • Significant emotional problems or a history of clinically significant psychiatric disorder.
  • Bleeding diathesis or intolerance to aspirin.
  • Anemia as defined as a hematocrit < 25%.
  • History of gastritis, bleeding gastric or duodenal ulcers.
  • History Type 1 or Type 2 diabetes, or fasting plasma glucose >125 mg/dL at screening or 75 gm OGTT with 2 hour glucose >140mg/dL.
  • History of illness that, in the opinion of the investigator, might confound the results of the study or pose an additional risk through participation.
  • History of ileal bypass, gastric bypass, or other condition associated with malabsorption.
  • Abnormal thyroid function tests.
  • AST or ALT > 1.5x the upper limit of normal.

  • Regular user of illicit drugs or history of drug abuse (including alcohol) within the previous 2 years.
  • Use of anabolic agents.
