Niacin for Treatment of Elevated Cholesterol and Triglycerides in HIV-Infected Patients

February 28, 2011 updated by: National Institute of Allergy and Infectious Diseases (NIAID)

A Pilot Study of the Safety, Efficacy, and Tolerability of Extended-Release Niacin (Niaspan) for the Treatment of Elevated Non-HDL Cholesterol and Elevated Triglycerides in HIV-Infected Subjects

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.

Detailed Description

Lipid disorders are common among patients with HIV and tend to worsen with potent antiretroviral therapy. Lipid-lowering drugs are not always effective, and few data address interactions between antiretroviral drugs and lipid-lowering agents. Additional agents for the treatment of lipid metabolism disorders in HIV-infected patients are needed. Niacin, which is highly effective for similar lipid disorders in the general population, may be effective in treating lipid disorders in patients with HIV.

This 48-week study consists of two steps. In Step 1, patients will begin a lipid-lowering diet and exercise regimen that will continue throughout the study. After 4 weeks on the regimen, patients will enter Step 2 of the study and will begin extended-release niacin therapy. During Step 2, niacin will be dose-escalated every 4 to 6 weeks over a 16-week period. At Weeks 14 and 20, the niacin dose will be determined by blood fat levels. Patients will remain on the dose set at Week 20 for the remainder for the study. If blood tests taken at Week 24 show that blood fat levels have not improved significantly, patients have the option of adding another fat-lowering drug to their therapy.

Patients will visit the clinic at entry and at Weeks 4, 8, 12, 18, 24, 32, 40, and 48. Patients may be asked to come to the clinic at Weeks 14 and 20 to receive additional study drug. Patients must fast for 8 to 12 hours before the screening visit and before each study visit in which blood will be drawn. Blood will be drawn throughout the study for fat, sugar, and insulin tests and for CD4 and CD8 cell counts.

Description

Inclusion Criteria:

  • HIV-infected.
  • Stable antiretroviral therapy for 3 months to 1 month prior to study entry and planning to stay on current therapy. No changes in antiretroviral therapy will be allowed in the 1-month period prior to study entry.
  • Fasting non-HDL-C >= 180 mg/dl and serum triglycerides > 200 mg/dl within 30 days of study entry.
  • Willing to stay on the Lipid-Lowering Diet and Activity Guide for the length of the study.
  • Women of reproductive potential must have a negative serum or urine pregnancy test performed within 14 days prior to study entry.
  • Agrees to use acceptable methods of contraception while receiving protocol-specified medication and for 4 weeks after stopping the medication. Patients who are not of reproductive potential are eligible without requiring the use of contraception.
  • Men who have been on stable testosterone replacement for at least 3 months prior to entry and plan to continue a stable dose during the study may enroll.
  • Hormone replacement therapy for postmenopausal women and for transgendered patients will be allowed, but not required. Oral contraceptive therapy will be allowed. Patients must be on stable hormone replacement therapy for at least 30 days prior to study entry and plan to continue a stable dose during the study.

Exclusion Criteria:

  • LDL-C >= 200 mg/dl or non-HDL-C > 250 mg/dl (if the LDL-C cannot be calculated because the triglycerides are > 400 mg/dl).
