What is being measured

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

  1. Breast milk immune regulators

    immune regulators in breast milk e.g. B-cell activating factor (BAFF); IL-7; Lactoferrin; sCD14, sIgA and TGF-beta levels at three time points-

    1. < 3-day postpartum (before 1st dose of supplementation)
    2. 7 wk postpartum (1wk after 2nd dose of supplementation)
    3. 15 wk postpartum

    Measured: Four months

Secondary outcomes (4)
  1. Infant T helper cell immune responses

    Mitogen stimulated whole blood IL-10, IL-13, IFN-gamma, IL-21 and IL-17 responses at two time points-

    1. 7 wk of age (1wk after 2nd dose of maternal supplementation , as well as, 1wk after first doses of pentavalent vaccination)
    2. 15 wk of age (1wk after three doses of pentavalent vaccination)

    Measured: Four months

  2. Infant innate immune responses

    Tall like receptor (TLR)-4 and TLR9 agonist stimulated whole blood TNF-alpha and IL-10 and IFN-alpha responses at two time points-

    1. 7 wk of age (1wk after 2nd dose of maternal supplementation , as well as, 1wk after first doses of pentavalent vaccination)
    2. 15 wk of age (1wk after three doses of pentavalent vaccination)

    Measured: Four months

  3. Infant vaccines (Hepatitis B, Tetanus and Oral polio) specific antibody responses

    Hepatitis B and Tetanus Toxoid specific plasma cell IgG responses at 15 wk of age (1wk after three doses of pentavalent vaccination) And Hepatitis B and Tetanus Toxoid specific IgG in plasma and Polio (3 serotypes) specific secretory IgA (sIgA) in stool at two time points-

    1. 7 wk of age (1wk after 2nd dose of maternal supplementation , as well as, 1wk after first doses of pentavalent vaccination)
    2. 15 wk of age (1wk after three doses of pentavalent vaccination)

    Measured: Four months

  4. Relative abundance of infant gut microbial community and gut inflammatory markers

    Next generation sequencing (NGS) of bacterial 16s rDNA (+qPCR) in extracted stool samples and assessment of infant gut inflammatory markers e.g. human β-defensin-2 (HBD2); Neopterin; α-1-antitrypsin (AAT); neutrophil gelatinase-associated lipocalin (NGAL)-2 and S100A at two time points-

    1. 7 wk of age (1wk after 2nd dose of maternal supplementation , as well as, 1wk after first doses of pentavalent vaccination)
    2. 15 wk of age (1wk after three doses of pentavalent vaccination)

    Measured: Four months

Questions about this trial

What is this clinical trial studying?

A Phase 2/3 study testing Vitamin A (<3-day postpartum), Vitamin A (6 wk postpartum) and Vitamin A (<3-day and 6 wk postpartum) in people with Vitamin A Deficiency, run by International Centre for Diarrhoeal Disease Research, Bangladesh at 1 site in Bangladesh.

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 1 inclusion and 4 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 21 Sep 2016. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Bangladesh. 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

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?

Breast milk immune regulators (time frame: Four months). 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 NCT02043223, 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 21 Sep 2016.
