Atazavanir/Ritonavir-based HAART in Children

August 25, 2014 updated by: The HIV Netherlands Australia Thailand Research Collaboration

The Study of Atazavanir/Ritonavir-based HAART in Thai HIV-infected Children

There are no data on efficacy, safety and pharmacokinetics of ATV/r-based HAART in HIV-infected Asian children. Therefore, the investigators aim to evaluate the pharmacokinetics, efficacy and safety of ATV/r-based HAART in Thai HIV-infected children.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Non-nucleoside reverse transcriptase inhibitor (NNRTI)-based HAART have been commonly prescribed as the first-line HAART for HIV-infected children in resource-limited settings. Protease inhibitor (PI)-based HAART are the recommended second-line regimen after failing NNRTI-based HAART. The most commonly used PI in Thailand is lopinavir/ritonavir (LPV/r). However, the metabolic complications of lopinavir/ritonaive (LPV/r) such as hyperlipidemia and lipodyrtrophy are common and a concern for HIV-infected children as it may contribute to the development of cardiovascular disease in the longer term. There are data on efficacy, safety and pharmacokinetics of ATV/r-based HAART in HIV-infected adults but none in children. Furthermore, many studies in both adults and children have shown that different ethnicities can result in different pharmacokinetic response to antiretroviral drugs. As a result of this, this study investigated the efficacy, safety and pharmacokinetics of ATV/r-based HAART in HIV-infected Asian children.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

6 years to 18 years (Child, Adult)

Accepts Healthy Volunteers

No

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
