Trial summary

There is a growing body of data suggesting that vitamin D modulates the host's immune response to acute respiratory infection (ARI). The primary aim of this study is to determine whether maternal vitamin D3 supplementation versus placebo decreases the incidence rate of microbiologically confirmed viral-associated ARI… Read more about this study

About this study

Official title: Maternal Vitamin D for Acute Respiratory Infections in Infancy (MDARI): a Nested Sub-study in a Randomized Controlled Trial of Vitamin D Supplementation During Pregnancy and Lactation in Dhaka, Bangladesh

There is a growing body of data suggesting that vitamin D modulates the host's immune response to acute respiratory infection (ARI). The primary aim of this study is to determine whether maternal vitamin D3 supplementation versus placebo decreases the incidence rate of microbiologically confirmed viral-associated ARI among infants in Dhaka, Bangladesh. Secondary outcomes include: A) incidence of ARI associated with specific major pathogens, B) incidence of clinical ARI (without the need for positive microbiology), and C) quantitative density of pneumococcal carriage. Infants will be followed from birth until 6 months of life. Among infants who meet at least one of the specific case definitions for ARI (see 'Detailed Description' section), nasal swab specimens will be collected. Respiratory samples will be analyzed by real-time polymerase chain reaction (qPCR) to identify a 7-virus panel (influenza A and B, respiratory syncytial virus, human metapneumovirus, adenovirus, and parainfluenza types 1, 2, and 3) plus quantitative density of S. pneumonia.

Read the detailed description

In this study, an acute respiratory infection (URTI and/or LRTI) has been clinically defined as:

  1. Upper respiratory tract infection (URTI)

A new-onset illness consisting of at least two of the following clinical criteria at any time during a surveillance week:

  • Caregiver-reported cough;
  • Caregiver-reported rhinorrhea;
  • Caregiver-reported nasal congestion; and,
  • Measured axillary temperature greater than or equal to 37.5°C.
  1. Lower respiratory tract infection (LRTI)
  2. New onset clinically-diagnosed LRTI:
  • Caregiver-reported cough AND/OR difficulty breathing during a surveillance week; AND,
  • Observed lower chest wall indrawing AND/OR elevated respiratory rate (60 breaths per minute or greater for infant up to 59 days of age, or 50 breaths per minute or greater for infant 60 days of age or older)
  1. Hospitalized LRTI
  • Hospitalization with physician diagnosis of pneumonia or bronchiolitis

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Vitamin D3 in people with Upper Respiratory Tract Infections and Lower Respiratory Tract Infections, run by The Hospital for Sick Children 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 7 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 20 Apr 2017. 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. 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 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?

Microbiologically confirmed viral acute respiratory infection (URTI and/or LRTI) (time frame: 0 to 6 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 NCT02388516, 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 20 Apr 2017.
