About this study

Official title: A Phase II, Randomized, Open-Label Study to Evaluate the Safety and Effectiveness of Two Antiretroviral Therapeutic Strategies: A Dual PI-Based HAART Regimen Versus a Multi-NRTI ART Regimen, in ART-Experienced Children and Youth Who Have Experienced Virologic Failure

HIV infected children and adolescents who have taken many anti-HIV drugs may have limited treatment options and are at high risk for progressing to AIDS. The purpose of this study is to determine whether an anti-HIV treatment regimen of 2 protease inhibitors (PIs) and 2 nucleoside reverse transcriptase inhibitors (NRTIs) is more effective than a regimen of 4 NRTIs in treatment-experienced children and adolescents who have failed previous anti-HIV treatment.

Read the detailed description

HIV infected children and adolescents on anti-HIV treatment regimens have traditionally had more difficulty with non-adherence and drug resistance than adults, often resulting in virologic failure. Additionally, HIV infected children with extensive exposure to antiretrovirals (ARVs) are likely to have fewer therapeutic options for salvage therapy, and their physicians find it difficult to choose regimens that will keep the HIV infection under control. This study will compare the efficacy of three 4-drug ARV salvage regimens in treatment-experienced, HIV infected children and adolescents who have experienced virologic failure.

This study will last at least 96 weeks. Participants will be randomly assigned to one of three groups. Group 1A will receive a dual-PI based regimen of lopinavir/ritonavir (LPV/r), saquinavir (SQV), and the NRTIs emtricitabine (FTC) and abacavir sulfate (ABC). Group 1B will receive a dual-PI based regimen of LPV/r, SQV, FTC, and tenofovir disoproxil fumarate (TDF). Group 2 will receive an NRTI-only regimen of ABC, lamivudine, zidovudine, and TDF.

There will be 11 study visits during Step I of this study. Medical history, a physical exam, and blood collection will occur at all visits. Dual-energy x-ray absorptiometry (DEXA) scans will occur at study entry and at Weeks 24, 48, 72, and 96. Urine collection will occur at most visits; participants will also take part in adherence modules at most visits. Participants will be asked to complete a pill count form at Weeks 4 and 24. Additionally, some study participants will be asked to participate in an intensive pharmacokinetics study at Week 4.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Tolerability of dual PI-based HAART versus multi-NRTI HAART salvage regimens (time to first intolerant event)

  2. 95% confidence interval (CI) for change in CD4% computed for PI-containing groups versus PI-sparing group

  3. 95% CI for change in BMD (both percent change in BMD and change in z-score from baseline) for each treatment group

Secondary outcomes (6)

  1. HIV-1 RNA

  2. growth and development markers

  3. toxicity

  4. adherence

  5. pharmacokinetics

  6. special virologic and immunologic parameters

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Abacavir sulfate, Emtricitabine and Lamivudine in people with HIV Infections, run by National Institute of Allergy and Infectious Diseases (NIAID) at 4 sites in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 9 inclusion and 10 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 1 Nov 2021. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 4 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Tolerability of dual PI-based HAART versus multi-NRTI HAART salvage regimens (time to first intolerant event). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00102206, which also lists 5 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 1 Nov 2021; AzTrials last refreshed its copy on 8 Nov 2026.
