The purpose of this study is to determine the effectiveness of fish oil supplements combined with the drug fenofibrate in treating elevated triglyceride levels in people taking anti-HIV drugs. The participants in this study will have shown no response to fish oil supplements or fenofibrate alone. Although highly active antiretroviral therapy (HAART) has decreased the morbidity and mortality caused by HIV infection, its use has been associated with lipid abnormalities, particularly elevations in serum triglycerides. Hypertriglyceridemia is a risk factor in the development of cardiovascular and cerebrovascular disease as well as pancreatitis. Lipid-lowering drugs called fibrates have been part of the recommended treatment for elevated triglycerides, but the response to fibrates is incomplete in a large proportion of people. Fish oil capsules containing large amounts of omega-3 fatty acids have been shown to decrease serum triglycerides. However, fish oil supplements or fibrates alone are often inadequate for treating hypertriglyceridemia in people taking HAART. This study will determine whether the combination of the two therapies will lower serum triglycerides in people on HAART more effectively than either therapy alone. This study comprises two steps. In Step I, participants will be randomly assigned to receive either fish oil supplements or fenofibrate. Participants will be evaluated for treatment response at Week 8. Those who have responded to their treatment will remain on their original single agent therapy through Week 18. Those who have not responded to treatment at Week 10 will move on to Step 2 and begin combination therapy with both fenofibrate and fish oil until Week 18. All participants will return at Week 22 for a follow-up visit. Except at the Week 10 visit, participants will be expected to fast prior to all study visits. Participants will remain on their individual HAART regimens for the duration of the study.

Protocol

This section provides details of the study plan, including how the study is designed and what the study is measuring.
Design Details
100 patients to be enrolledTotal number of participants that the clinical trial aims to recruit.
Treatment Study
These studies test new ways to treat a disease, condition, or health issue. The goal is to see if a new drug, therapy, or approach works better or has fewer side effects than existing options.

How participants are assigned to different groups/arms
In this clinical study, participants are placed into groups randomly, like flipping a coin. This ensures that the study is fair and unbiased, making the results more reliable. By assigning participants by chance, researchers can better compare treatments without external influences.

Other Ways to Assign Participants
Non-randomized allocation: Participants are assigned based on specific factors, such as their medical condition or a doctor's decision.
None (Single-arm trial): If the study has only one group, all participants receive the same treatment, and no allocation is needed.

How treatments are given to participants
Participants are divided into different groups, each receiving a specific treatment at the same time. This helps researchers compare how well different treatments work against each other.

Other Ways to Assign Treatments
Single-group assignment: Everyone gets the same treatment.
Cross-over assignment: Participants switch between treatments during the study.
Factorial assignment: Participants receive different combinations of treatments.
Sequential assignment: Participants receive treatments one after another in a specific order, possibly based on individual responses.
Other assignment: Treatment assignment does not follow a standard or predefined design.

How the interventions assigned to participants is kept confidential
Everyone involved in the study knows which treatment is being given. This is typically used when it's not possible or necessary to hide the treatment details from participants or researchers.

Other Ways to Mask Information
Single-blind: Participants do not know which treatment they are receiving, but researchers do.
Double-blind: Neither participants nor researchers know which treatment is given.
Triple-blind: Participants, researchers, and outcome assessors do not know which treatment is given.
Quadruple-blind: Participants, researchers, outcome assessors, and care providers all do not know which treatment is given.
