About this study

Official title: Efficacy of Allergy Immunotherapy in Preventing Asthma Morbidity in Atopic, Wheezing Children (Age 18 Months - 3 Years)

In this clinical study we aim to determine the effect of allergy immunotherapy in decreasing asthma and allergy related disease in children who had multiple episodes of wheezing and who are at high risk for developing persisting asthma. These risks include a history of asthma in the parents, allergies to environmental allergens (such as dust mite, cockroach or mouse) and other allergic diseases such as eczema or food allergies. Allergy Immunotherapy is not new and has been practiced for many years to treat asthma and environmental allergies in older children and adults, but has not yet been systematically studied in young children.

Wheezing, Asthma, Allergy
Being tested
Allergen extracts (subcutaneous injections), Standard of care

What participants receive

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

  • Allergen extracts (subcutaneous injections)Biological

    Allergy immunotherapy consists of regular subcutaneous injections of an individualized mixture of allergen extracts according to the allergy sensitization profile of each child. Increasing doses of allergen extract are given in 1-2 injections until a predetermined maintenance dose is reached. This maintenance dose varies by extract and accords to the general practice guidelines of immunotherapy. To increase safety, the cumulative monthly maintenance doses are divided into biweekly visits during the maintenance phase (year 2-3)

  • Standard of careOther

    standard of care asthma and allergy treatment

What is being measured

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

  1. Asthma Severity as Measured by the Asthma Severity Score (Averaged up to 36 Months)

    The Asthma Severity Score is a customized score created for this study due to the lack of standardized instruments for this age group. It takes into account asthma symptom severity and frequency, as well as asthma medication dosing and potency. Data was collected at baseline and every 2 weeks through interviews conducted over the phone. If the caregiver could not be reached by the phone, the interview was conducted at the next face-to face opportunity (study or injection visit). The minimum score on this scale is 0 (no asthma symptoms and no asthma medicines used during the 14 day interview period). The maximum score is 224 (uncontrolled severe asthma with severe cough, shortness of breath and wheezing on 14 of 14 days, using Albuterol 2 puffs 4x/day, budesonide/formoterol 160ug/4.5ug 2 puffs twice daily and Montelukast 4mg daily on 14 of 14 days). Scores calculated from the collected data were averaged to produce one reported value at baseline and year 1, 2 and 3.

    Measured: baseline and every two weeks up to end of study (up to 36 months)

Secondary outcomes (3)
  1. Number of Newly Gained Allergic Sensitizations as Assessed by Serum Specific Immunoglobulin E (IgE) Testing

    Young children with allergies tend to develop additional environmental allergies over time. This study investigated if allergy immunotherapy could be used to prevent the development of new allergic sensitizations. Participants were tested for sensitivity to a panel of 8 common environmental allergens. Testing was conducted via serum specific immunoglobulin E (IgE) testing. A test was considered negative (non-allergic) if the specific IgE level was <0.35 kIU/L (Kilo International Units/Liter) and positive (allergic) if the levels was >0.35 kIU/L. A "test pair" is the result of a serum IgE test, for a specific allergen, done at two different times. Test pairs can be negative-negative, negative-positive (newly gained allergic sensitization), positive-negative (lost sensitization) or positive-positive. Reported values indicate the total number of newly gained allergic sensitization (negative-positive) for the group.

    Measured: Baseline and end of treatment (36 months)

  2. Peripheral Blood T Regulatory Cells as a Percentage of CD4+ (Cluster of Differentiation 4) Cells

    T regulatory cells are thought to play a role in mediating the effects of immunotherapy in increasing allergen tolerance and dampen the clinical expression of allergy. However, existing studies have not found clear relationship between numbers of T regulatory cells in blood and effect of immunotherapy. The aim of this analysis was to observe potential changes in T regulatory cell numbers in response to immunotherapy in this age group. Peripheral blood cells were acquired and analyzed for T regulatory (Treg) cell markers. In molecular biology, CD4+ (cluster of differentiation 4), a particular cell marker, is a glycoprotein found on the surface of immune cells such as T helper cells and certain groups of T regulatory cells. Testing was done at baseline and then every 12 months. Reported values represents the percentage of CD4+ that are Treg cells.

    Measured: Baseline and every 12 months until end of treatment (36 months)

  3. Incidence Rate of Systemic Corticosteroid Bursts (CSB) Per Child

    Any reported use of consequent systemic corticosteroid use due to asthma exacerbation counted as one "corticosteroid burst" (CSB). For example, if a child used 5 days of prednisolone due to asthma exacerbation, this counted as one corticosteroid burst (CSB). An interval of at least 7 days was determined to be necessary to count 2 courses of systemic corticosteroids as separated bursts.

    The presented data reflect the intention-to-treat analysis. The time between baseline and each participant's study end time was counted towards the "years in study". The incidence rate describes the number of CSB per child per "year in study".

    Measured: From baseline through end of study (maximum 36 months)

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing Allergen extracts (subcutaneous injections) in people with Wheezing and Asthma, run by Albert Einstein College of Medicine 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 5 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: finished, as of the sponsor's last update on 28 May 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.

What does this combined phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

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?

Yes. Results are posted in the registry (first posted 28 May 2019). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Asthma Severity as Measured by the Asthma Severity Score (Averaged up to 36 Months) (time frame: baseline and every two weeks up to end of study (up to 36 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 NCT01028560, which also lists 6 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 28 May 2019.
