Trial summary

The purpose of this study is to assess the responses in the immune system of infants after they receive the vaccine against diphtheria, tetanus, and pertussis (DTaP). The investigators will do this by studying the immune cells and allergy responses in the blood prior to and after receipt of the third DTaP vaccine. Read more about this study

About this study

The purpose of this study is to assess the responses in the immune system of infants after they receive the vaccine against diphtheria, tetanus, and pertussis (DTaP). The investigators will do this by studying the immune cells and allergy responses in the blood prior to and after receipt of the third DTaP vaccine.

Read the detailed description

This is a single-site study of infants who are scheduled to receive their third series (~6 month) vaccinations, as routine care, to investigate whether the diphtheria, tetanus, and pertussis (DTaP) vaccination has an effect on specific immunoglobulin E (IgE) levels to milk, egg, or peanut. Infants will be assigned to one of two groups depending on the infant's sensitization to milk, egg, and peanut.

Being tested
Skin prick allergen test, Blood draw
Keywords
Milk Allergy, Egg Allergy, Peanut Allergy, Infant Vaccination

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Skin prick allergen testProcedure or surgery

    To test for hypersensitivity to milk, egg, or peanut

  • Blood drawProcedure or surgery

    Also called venipuncture

Negative blood test to allergyA negative skin prick test to egg, milk, and peanut and a negative Immunoglobulin E (IgE) to egg, milk, and peanut.

What is being measured

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

  1. Allergen-specific IgE

    Magnitude of increase of allergen-specific IgE. For each child, the maximum allergen-specific IgE change to milk, egg, or peanut will be considered as the primary endpoint.

    Measured: baseline and day 28

Questions about this trial

What is this clinical trial studying?

An observational study of Food Hypersensitivity, run by National Institute of Allergy and Infectious Diseases (NIAID) at 1 site in United States.

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 17 inclusion and 8 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: stopped early, as of the sponsor's last update on 23 Jul 2019. 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 United States. 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?

The study was stopped early (reason given: Lack of enrollment.). 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?

Allergen-specific IgE (time frame: baseline and day 28). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 23 Jul 2019.
