Study Description
Brief Summary:
To assess the efficacy and safety of Nidadd (extended-release niacin) in patients with hyperlipidemia.

Condition or disease Intervention/treatment Phase
Hyperlipidemia Drug: Nidadd Phase 3

Detailed Description:

This is a randomized, double-blind, placebo-controlled, and multicenter study. A total of at least 50 patients will be recruited to achieve 40 evaluable patients required to assess the safety and efficacy of escalating doses of extended-release Nidadd in hyperlipidemic patients.

  1. The trial begins with measurement of baseline lipid levels. Fasting blood samples will be collected at screening and each treatment visit (except visit 3) for lipid analysis and safety monitoring. Chemistry laboratory tests and hematological testing are performed periodically. Patient’s diet education will be given by dieticians or appropriately trained counselors at visit 1 and 2.
  2. Patients who are taking any lipid-modifying drugs will be required to go through a 4-week washout / diet-controlled period prior to randomization (visit 2).
  3. Treatment duration is 16 weeks in total: Patients randomized to treatment with Nidadd will receive 500 mg for the first 8 weeks of the medication period. For another 8 weeks, the dose is then increased to 1000 mg and is maintained to the end of the study. The patients in control group will take placebo in a same fashion as that of Nidadd group throughout entire 16 weeks.
  4. The primary measure of efficacy is the change from baseline in serum HDL-c level. Secondary measures of efficacy are changes from baseline in serum total cholesterol, LDL-c, and triglycerides.
  5. Safety and tolerability will be evaluated from adverse events, number of patients who prematurely discontinue the trial because of adverse events, and laboratory measures.
