About this study

Official title: An Open-Label Study to Evaluate the Safety, Tolerance, Antiviral Activity, and Pharmacokinetics of Emtricitabine in Combination With Efavirenz and Didanosine in a Once-Daily Regimen in HIV Infected, Antiretroviral Therapy Naive or Very Limited Antiretroviral Exposed Pediatric Subjects

Treatment of HIV-infected patients involves combining drugs from different classes of anti-HIV drugs. One preferred regimen for adults is 2 nucleoside reverse transcriptase inhibitors (NRTIs) and 1 protease inhibitor (PI). For children, this regimen may be too complicated or the drugs may be too difficult to take by mouth. The purpose of this study was to determine the long-term safety and effectiveness of daily didanosine (ddI), efavirenz (EFV), and emtricitabine (FTC) in pediatric patients who had taken few or no anti-HIV drugs.

Read the detailed description

Anti-HIV treatment options are limited for pediatric patients because combination therapies recommended for adults may not be appropriate for children or adolescents. Few PIs are available in formulations appropriate for pediatric patients, and complex dosing schedules and food requirements may be detrimental to treatment adherence. A once-daily regimen of the NRTIs ddI and FTC and the nonnucleoside reverse transcriptase inhibitor (NNRTI) EFV has been shown safe and well tolerated in adults.

This Phase I/II open label study evaluated the long-term safety and efficacy of a ddI, FTC, and EFV regimen in pediatric patients. All study patients were either absolutely naive to antiretroviral therapy or had received less than or equal to 56 days perinatal prophylaxis or less than 7 days of cumulative antiretroviral therapy prior to study entry, and had a plasma screening plasma HIV-1 RNA levels >= 5000 copies/mL. This study was written to characterize the disposition of FTC, determine the PK data for ddI-EC QD, comparing the bio-availability of the enteric coated formulation with ddI pediatric powder for oral solution, and to provide insight into the age related pharmacokinetics differences observed in this and other studies.

HIV infected pediatric patients were stratified into three age Groups: Group 1: 90 days to <3 years of age; Group 2: 3 years to 12 years of age (inclusive); and Group 3: 13 to 21 years of age (inclusive). The initial study doses for the triple drug regimen was FTC, 6 mk/kg up to a maximum of 200 mg once daily, for EFV, the dose for age Group 1 was determined in PACTG 382 and dose adjusted for body size, and the doses for age Groups 2 and 3 were defined in the dosing table of the protocol of up to a maximum of 600 mg once daily as a capsule or 720 mg as an oral solution; for ddI, 240 mg/m2 up to a maximum of 400 mg once daily. Comparison of age groups was not required as per the protocol.

Patients were followed for a maximum of 192 weeks; all patients were to receive ddI, EFV, and FTC together once daily. Study visits occurred at study entry, Weeks 2,and 4, and every 4 weeks thereafter. Blood collection, medical history assessment, and a physical exam occurred at all visits; urine collection occurred at selected visits. Intensive pharmacokinetic (PK) studies was done at Weeks 2 and 12 to determine if dose adjustments were required for any of the drugs. If virologic failure was determined, PK studies was repeated 4 weeks after adjustments in therapy. Parents or guardians were asked to complete treatment adherence questionnaires at some visits. Some patients were also asked to participate in an additional PK study after Week 16 or week 96.

What is being measured

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

  1. Proportion of Participants Who Developed Grade 3 or 4 Adverse Events Attributed to the Study Treatment.

    Adverse events were graded using the Division of AIDS (DAIDS) Table for Grading the Severity of Adult and Pediatric Adverse Events (DAIDS AE Grading Table), Version 1.0, December 2004, Clarification August 2009, which is available on the RCC website at (http://rcc.tech-res.com/). Adverse Events of Grade 3 or 4 laboratory abnormalities or signs and symptoms that were judged by the study team to be possibly or probably related to the study treatment.

    Comparisons between age groups were not required as per protocol.

    Measured: At study entry, weeks 2 and 4, every 4 weeks up to week 96 and every 6 weeks thereafter for Group 1 participants and at study entry, weeks 2 and 4, every 4 weeks up to week 144 and every 12 weeks thereafter for Groups 2 and 3

  2. Proportion of Participants With Suppression of HIV Viral Load to Less Than 400 Copies/ml at Week 16

    Proportion was calculated as number of participants with HIV-1 RNA <= 400 copies/ml relative to the number of participants with HIV-1 RNA measured at that time point.

    Measured: At week 16

  3. Proportion of Participants With Suppression of HIV Viral Load to Less Than 50 Copies/ml at Week 16

    Proportion was calculated as number of participants with HIV-1 RNA <= 50 copies/ml relative to the number of participants with HIV-1 RNA measured at that time point.

    Measured: At week 16

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing Didanosine (ddI), Efavirenz (EFV) and Emtricitabine (FTC) in people with HIV Infections, run by National Institute of Allergy and Infectious Diseases (NIAID) at 18 sites in 2 countries.

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 8 inclusion and 23 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 5 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 18 sites in United States, Puerto Rico. 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 combined phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

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?

Yes. Results are posted in the registry (first posted 17 Oct 2017). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Proportion of Participants Who Developed Grade 3 or 4 Adverse Events Attributed to the Study Treatment. (time frame: At study entry, weeks 2 and 4, every 4 weeks up to week 96 and every 6 weeks thereafter for Group 1 participants and at study entry, weeks 2 and 4, every 4 weeks up to week 144 and every 12 weeks thereafter for Groups 2 and 3). 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 NCT00016718, which also lists 2 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 5 Nov 2021.
