About this study

Official title: ANRS EP59 CLEAC : Physiopathological Study of Immunovirological Evolution of Perinatally HIV-1 Infected Children Depending on Early (Before 6 Months) or Late (After 2 Years) Antiretroviral Therapy Introduction.

The study aims to define and compare the immunological characteristics (lymphocyte subpopulations, specific immunity against HIV, lymphocyte activation, inflammatory parameters) and the virological characteristics (study of viral reservoir) between 2 groups of vertically-HIV-1-infected children, between 5 and 17-year-of-age, who started cART before 6 months-of-age ("early treatment" group) or after 24 months-of-age ("late treatment" group) with an initial virologic success (HIV-1 RNA <400 copies / mL reached no later than 24 months after the start of cART), whatever the later evolution of the viremia.

Moreover, the viral reservoir will be deeply characterized in 10 children (5 patients in each group) with sustained control of the HIV-1 viremia under cART (≥ 90% of HIV-1 RNA measures <400 copies /mL): quantification of the reservoir in the lymphocyte subpopulations and study of the inductibility of the viral reservoir.

Read the detailed description

This is a cross-sectional study, multicenter, without direct benefit, among vertically HIV-1 infected children, aged 5 to 17 years, followed in centers participating in the ANRS CO10 EPF cohort located in Ile-de-France. Eligible children are not necessarily included in the cohort. The sample will consist of two age groups of equal size (5-12 years and 13-17 years).

Patient recruitment will be conducted in the centers of the ANRS CO10 EPF cohort located in Ile de France (Paris area). 80 children will be included, previously included or not in the ANRS CO10 EPF cohort. Our investigations will involve two blood samples, taken during two successive visits of the children in the hospitals where they are usually followed. Finally, a third blood sample will be taken during a third visit only for the 10 children participating in the substudy of the viral reservoir. All medical data since birth will be prospectively collected for children included in the ANRS CO10 EPF cohort, and retrospectively collected in the other cases.

What is being measured

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

  1. Immune status

    The immune status will be defined by T lymphocyte subpopulations

    Measured: Baseline

  2. Virological status

    Peripheral blood HIV DNA levels

    Measured: Baseline

  3. Immune status

    The immune status will be defined by inflammatory parameters : cytokines and chemokines

    Measured: 6 months after baseline

  4. Immune status

    The immune status will be defined by HIV-specific T cell response

    Measured: Baseline

  5. Immune status

    The immune status will be defined by lymphocyte activation (HLA-DR)

    Measured: Baseline

Secondary outcomes (3)
  1. Comparison of immune and virological statuses of early and late treatment groups

    Two groups of vertically-HIV-1-infected children, between 5 and 18-year-of-age, will be compared: the "early treatment" group that comprises children who started HAART before 6 months-of-age, and the late treatment" group those who started HAART after 24 months-of-age.

    Measured: Baseline

  2. Viral reservoir : lymphocyte subpopulation

    Total HIV- DNA will be quantified by ultrasensitive PCR in CD4 T cell subsets sorted according their differenciation status for 10 children (5 patients in each group) with sustained control of the HIV-1 viremia under HAART ( ≥ 90% of HIV-1 RNA measures <400 copies / ml).

    Measured: One year after baseline

  3. Viral reservoir : inductibility

    Inductibility of the viral reservoir will be quantified by ultrasensitive HIV-RNA RT- PCR in supernatants after coculture of CD4 T cells.

    Measured: One year after baseline

Questions about this trial

What is this clinical trial studying?

A study testing Blood draw in people with HIV Infection, run by ANRS, Emerging Infectious Diseases at 11 sites in France.

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 10 inclusion and 9 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: status not confirmed, as of the sponsor's last update on 18 Jan 2019. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 11 sites in France. 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.

Are results available for this study?

Results are not available in the source record.

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?

Immune status (time frame: Baseline). The study lists 5 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 NCT02674867, which also lists 1 linked publication.

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 18 Jan 2019.
