CLINICAL TRIALS PROFILE FOR NIASPAN

All Clinical Trials for NIASPAN

Trial ID	Title	Status	Sponsor	Phase	Start Date	Summary
NCT00046267 ↗	Niacin for Treatment of Elevated Cholesterol and Triglycerides in HIV-Infected Patients	Completed	National Institute of Allergy and Infectious Diseases (NIAID)	N/A	1969-12-31	The purpose of this study is to evaluate the safety, efficacy, and tolerability of extended-release niacin (Niaspan) in improving the level of fats in the blood of HIV-infected patients.
NCT00062556 ↗	Effect of Niacin ER/Lovastatin on Peak Walking Time & Claudication Onset Time in Patients With Intermittent Claudication	Completed	Kos Pharmaceuticals	Phase 3	2003-01-01	The purpose of this study is to evaluate if Niacin ER/Lovastatin, at two different doses, compared to diet control (this group will receive a tablet containing 50 mg. of immediate-release niacin) is a safe and effective medicine in subjects with leg pain caused by a narrowing of their leg arteries, a condition called intermittent claudication. At least 366 subjects with leg pain caused by a narrowing of their leg arteries will participate in this study. Niacin ER/Lovastatin is a combination of two FDA (United States Food and Drug Administration) approved cholesterol modifying medications: Niaspan® (extended-release niacin) and lovastatin, a statin (the same medicine found in Mevacor®). Niacin ER/Lovastatin was approved by the FDA under the name of Advicor® for use in the treatment of elevated cholesterol. The use of Niacin ER/Lovastatin in the treatment of peripheral arterial disease and symptomatic relief of intermittent claudication is considered investigational. An investigational use is one that is not approved by the FDA.
NCT00071266 ↗	The Dose Response of Niacin ER/Lovastatin on Peak Walking Time (PWT) in Patients With Intermittent Claudication - TROPIC	Completed	Kos Pharmaceuticals	Phase 3	2003-10-01	The purpose of this study is to compare the dose response and safety of Niacin ER/Lovastatin, Niaspan® and Lovastatin with each other, in subjects with leg pain caused by a narrowing of their leg arteries. At least 870 subjects, with leg pain caused by a narrowing of their leg arteries will take part in this study. Both Niaspan and lovastatin (Mevacor®) are approved by the United States Food and Drug Administration (FDA) to treat high cholesterol. Niacin ER/Lovastatin (Advicor®), a combination of these two drugs, is also approved by the FDA to treat high cholesterol. The use of Niacin ER/Lovastatin to treat narrowing of leg arteries and relieve "intermittent claudication" (leg pain caused by narrowing of the arteries in the leg) is considered investigational. An investigational use is one that is not approved by the FDA.
NCT00079638 ↗	Comparative Efficacy Evaluation of Lipids When Treated With Niaspan & Statin or Other Lipid-Modifying Therapies-COMPELL	Completed	Kos Pharmaceuticals	Phase 4	2004-04-01	The purpose of this study is to evaluate the effectiveness of first-line treatment using Niaspan (an extended release version of niacin) and statins versus other drugs that lower lipid levels, in subjects with elevated fat levels in their blood (dyslipidemia). Statins are a class of medication that is often prescribed to patients who need to lower their cholesterol levels.
NCT00108485 ↗	Study of the Use of Niaspan for Treatment of Dyslipidemia in Diabetic Nephropathy	Terminated	University of Miami	Phase 3	2005-04-01	The primary purpose of this study is to test the effectiveness and tolerability of Niaspan® to improve the levels of blood fats ("good" and "bad" cholesterol and triglyceride levels) in people who have kidney damage due to diabetes. A secondary goal is to test whether Niaspan® slows down further development of kidney damage.

Clinical Trials Update on NIASPAN

Recent Clinical Trials and Research Developments

Trial Name	Phase	Purpose	Status	Key Findings	Reference
AIM-HIGH (2011)	Phase III	Assess efficacy of niacin + statin in reducing cardiovascular events	Completed	No significant reduction in cardiovascular outcomes; high dropout rate due to flushing	[1]
HPS2-THRIVE (2014)	Phase III	Evaluate long-term safety and efficacy of extended-release niacin	Completed	Mixed results; no significant benefit; increased risk of adverse events	[2]
Niacin in PAF Trial (2020)	Phase II	Investigate niacin's potential in reducing post-acute coronary syndrome risk	Ongoing/Results pending	Preliminary data suggest reduction in triglycerides; cardiovascular outcomes under review	[3]
N.B.	—	Ongoing trials focus on combination therapies, safety, and lipid-lowering efficacy with novel formulations	Various, ongoing	Emphasis on combination with PCSK9 inhibitors and safety profile optimization	—

Regulatory Status and Label Updates

• FDA approval: NIASPAN remains FDA-approved for the reduction of elevated total cholesterol, LDL-C, apolipoprotein B, and triglycerides in adults with coronary heart disease or at risk.
• Label updates (2022): No major changes were made; warnings about flushing, hepatotoxicity, and glucose intolerance remain emphasized.
• Recent regulatory reviews: EMA and other agencies currently reassess data regarding cardiovascular benefit claims; no significant label modifications announced.

Clinical Efficacy and Safety Profile

• Efficacy: Effective in lowering triglycerides and LDL-C; less effective in raising HDL-C compared to other agents.
• Safety concerns: Flushing (most common), hepatotoxicity, insulin resistance, and gastrointestinal discomfort.
• Patient tolerability: Use of aspirin prior to dosing reduces flushing; monitoring liver enzymes is advised.
