About this study

Official title: A Randomized Study of Cotrimoxazole Prophylaxis and Longer Breastfeeding Duration to Improve Survival Among HIV-Exposed Infants in Botswana

The purpose of this study is to find ways to improve infant health and survival among infants whose mothers are HIV-infected but who do not themselves have HIV.

Read the detailed description

As improved MTCT prevention interventions reduce the number of HIV-infected infants in the antepartum and peripartum periods, interventions to improve HIV-free survival among HIV-uninfected infants are needed. Morbidity and mortality are increased among HIV-uninfected infants born to HIV-infected mothers, and reduced infant survival among HIV-exposed infants may lead to as many deaths as HIV infection itself. In Botswana, the use of formula feeding or shorter breastfeeding may worsen the problem of early infant mortality among HIV-exposed infants.

The study will enroll pregnant or postpartum HIV-1-infected women, and their HIV-uninfected infants in Botswana. At 2-4 weeks of age, live HIV-uninfected infants will be randomized to receive either double-blinded cotrimoxazole (CTX) or placebo from 2-4 weeks through 15 months. In addition, breastfeeding (BF) infants will be randomized to BF until either 6 or 12 months of age. Children will be followed prospectively until 18 months of age. The primary endpoint will be survival at 18 months comparing all infants in the CTX vs. placebo arms, and by randomized duration of BF among those BF at randomization. Secondary endpoints will evaluate survival and morbidity/mortality at 12 and 15 months; HIV-free survival to 18 months; and the safety of CTX prophylaxis. Secondary observational objectives include comparing MTCT and mortality by initial feeding method (formula feeding or any BF > 1 month), and an analysis of maternal characteristics as predictors for initial feeding choice and HIV-free survival. All women and infants will receive standard antenatal and peripartum prophylaxis from the Botswana government for MTCT prevention (PMTCT), and will choose a feeding method with counseling. Breastfeeding infants will receive infant nevirapine (NVP) prophylaxis or will be protected from MTCT by the use of maternal HAART.

What is being measured

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

  1. Survival

    The primary outcome measure is survival at 18 months comparing all infants in the CTX vs. placebo arms, and by randomized duration of breastfeeding among those breastfeeding at randomization.

    Measured: 18 months of age

Secondary outcomes (3)
  1. HIV-free Survival

    Secondary outcome measures will evaluate HIV-free survival between 4 weeks and 18 months among infants randomized to either 6 months or 12 months of breastfeeding.

    Measured: 18 months of age

  2. Safety of CTX prophylaxis

    Secondary outcome measures will evaluate the safety of CTX prophylaxis through 18 months

    Measured: 18 months

  3. Morbidity and mortality

    Secondary outcome measures will evaluate morbidity and mortality to 18 months.

    Measured: 18 months of age

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing cotrimoxazole prophylaxis, exclusive breastfeeding until 6 months of age and breastfeeding for 12 months in people with HIV Infections and Neutropenia, run by Harvard School of Public Health (HSPH) at 3 sites in Botswana.

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 4 inclusion and 2 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 9 Sep 2019. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 3 sites in Botswana. 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. Some participants in this study may receive a placebo. 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?

Survival (time frame: 18 months of age). 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 NCT01229761, which also lists 3 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 9 Sep 2019.
