About this study

Official title: Optimizing Pediatric HIV-1 Treatment, Nairobi, Kenya (0-4.5 Month Randomized Controlled Trial)

Given the high mortality associated with infant HIV-1 and the fact that surrogate markers are poorly predictive of mortality risk,empiric highly active antiretroviral therapy (HAART) initiation is started in infants younger than 12 months. A problem with this approach is that it obligates infants to life-long therapy, which may be associated with cumulative drug toxicity, poor adherence, and treatment failure. Early HAART for prevention of mortality during the first 2 years of life has potential to salvage immune function and alter viral set-point, allowing withdrawal of therapy, perhaps for several years, until subsequent CD4% decline requires it. This untested approach is attractive because it combines the survival benefits of early pediatric HAART therapy with the benefits of antiretroviral deferral.

One hundred and fifty infants who initiated HAART at <13 months of age will be treated with HAART regimen for 24 months after which those who have immune reconstitution and adequate growth (~100) will be randomized to continued versus deferred therapy. Clinical outcomes, growth, and toxicity will be compared in these children to determine if interruption is a safe and beneficial strategy. Follow-up in this studies will be closely monitored by an external Data Safety and Monitoring Board (DSMB).

Read the detailed description

Hypothesis: Deferring antiretroviral therapy in infants who have immune reconstitution and adequate growth following early therapy of primary infection (initiated HAART during primary infection at less than 13 months of age) will not compromise clinical status or growth and may spare antiretroviral toxicity.

Specific Aim/Primary Objective: To compare growth and morbidity in infants (who initiated HAART during primary infection at less than or equal to 13 months of age with subsequently normalized CD4% and growth following 24 months of HAART) randomized to deferred versus continuous therapy and followed for an additional 18 months.

Secondary Aim/Secondary Objective: To determine predictors of non-progression of HIV among the infants, including: age, adherence, HIV-1 specific immune responses, baseline HIV-1 RNA, CD4 percent and immune activation.

Design: Randomized clinical trial involving HIV-1 treatment of infants (<13 months old) for 24 months, followed by randomization and 18 months follow-up of children randomized to continued versus deferred treatment. This trial is unblinded.

Population: HIV-1 infected infants (<13 months) newly initiating HAART and HIV-1 infected infants already receiving HAART who initiated HAART at age <13 months will be enrolled. After 24 months of treatment follow-up, children with CD4% > 25% and normalized growth will be retained in the study and randomized.

Sample size: 150 infants will be enrolled of which 100 are expected to be eligible for randomization (50 in each arm).

Treatment: All infants will be treated with HAART according to WHO and Kenyan national guidelines. The specific regimens that will be used as a part of this study are:

First line regimen

  • AZT/3TC/NVP (zidovudine/lamivudine/nevirapine)
  • d4T/3TC/NVP (stavudine/lamivudine/nevirapine)
  • AZT/3TC/ABC (zidovudine/lamivudine/abacavir)
  • d4T/3TC/ABC (stavudine/lamivudine/abacavir)
  • ABC/3TC/NVP (abacavir/lamivudine/nevirapine)

Second line regimen - ddI/ABC/LPV/r (didanosine/abacavir/lopinavir-ritonavir (Kaletra))

For infants with prior exposure to nevirapine as part of PMTCT:

First line regimen

  • AZT/3TC/LPV/r (zidovudine/lamivudine/lopinavir-ritonavir (kaletra))

What is being measured

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

  1. Growth at 18 Months Post-randomization

    Weight and height will be transformed to the weight-for-age Z-score (i.e., WAZ) and height-for-age Z-score (i.e., HAZ) using World Health Organization Child Growth Standards, taking into account the infant's age and gender.

    Measured: 18 months of post-randomization follow-up

Secondary outcomes (1)
  1. Morbidity

    severe adverse events including death, pneumonia, diarrhea, and other adverse events

    Measured: 18 months post-randomization

What does the primary outcome measure?

Growth at 18 Months Post-randomization (time frame: 18 months of post-randomization follow-up). 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 NCT00428116, which also lists 10 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.
