Trial summary

In Finland, the estimated prevalence of physician-diagnosed food allergy in 1-4 year old children is 9%, and the most common allergen is milk. The overall food allergy has been reported to be 3.7%. Hen's egg allergy is among the most common food allergies in childhood. Read more about this study

About this study

Official title: The Effect of Per Oral Immunotherapy in Severe IgE Mediated Egg, Milk and Nut Allergy in Adults

In Finland, the estimated prevalence of physician-diagnosed food allergy in 1-4 year old children is 9%, and the most common allergen is milk. The overall food allergy has been reported to be 3.7%. Hen's egg allergy is among the most common food allergies in childhood. In addition, it predicts later development of allergic disease such as asthma. Most of the egg and milk allergy is transient and disappears in childhood. Currently, the standard of care for food allergy includes strict allergen avoidance. However, oral immunotherapy has been under investigation in children milk, egg, and wheat allergy. Previously, induction of clinical egg tolerance has been reported with egg oral immunotherapy in children aged from 3 to 13 years. In adults, strict avoidance is still the standard care but there is also growing interest in treatment of severe food allergy with oral immunotherapy or anti-IgE.

The investigators aim to analyse the results of per oral immunotherapy treatment in severe IgE-mediated egg, milk, and nut allergy in adults.

Could severe egg, milk and nut allergy be treated with oral immunotherapy treatment in stead of total allergen avoidance and could desensitization thus be achieved?

Read the detailed description

Up to 100 subjects are studied. All subjects are adults having no other severe chronic diseases. The subjects belong to four different groups:

  1. 30 18-50 year olds who start per oral immunotherapy treatment in severe egg allergy.
  2. 30 18-50 year olds who start per oral immunotherapy treatment in severe milk allergy.
  3. 30 18-50 year olds who start per oral immunotherapy treatment in severe nut allergy.
  4. 10 milk allergic 18-50 year olds that have been treated as pilot patients with milk hyposensitisation treatment.

The diagnosis of milk or egg allergy is verified with positive history, skin prick test, egg, milk and nut allergen specific IgE antibodies. In addition, food allergy is verified with an allergen specific challenge test.

Atopic subjects may have simultaneously other allergies. Intermittent mild asthma, and mild and moderate persistent asthma are tolerated and treatment with inhaled steroids and other asthma medication is allowed. Atopic subjects may have additional skin symptoms. Quality of life, anxiety and patient history data is collected by questionnaires. All patients undergo a spirometry with a bronchodilatation test, fractional exhaled nitric oxide and a methacholine challenge before and a year after oral immunotherapy. Those with test results diagnostic for asthma are treated with asthma medication before hyposensitisation treatment is started.

Exclusion criteria: adults with instable cerebrovascular or heart disease, active autoimmune disease or cancer, or use of betablocker agents. In addition, poorly controlled asthma or FEV1 < 70% are not tolerated.

In oral immunotherapy, increasing doses are given first observed, and then daily at home. If the subject does not tolerate a given dose and symptoms are mild, then that dose or the previously tolerated one is repeated, and the protocol proceeds as outlined. If the subject experiences significant symptoms, then the protocol is stopped, and the highest tolerated dose is used as the starting daily one.

What is being measured

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

  1. Number of the Patients That Achieve Higher Tolerance of Allergen With Immunotherapy

    Number of the patients that achieve higher tolerance of allergen with immunotherapy in one year than the measured baseline allergen challenge shows.

    Measured: One year

Secondary outcomes (3)
  1. Effect of Therapy on Lung Function.

    Does hyposensitisation change lung function (do spirometry tests show difference from the baseline values (= before immunotherapy) after the immunotherapy) ?

    Measured: One year

  2. Does Oral Immunotherapy Change Bronchial Hyperreactivity?

    Does bronchial hyperreactivity (measured with methacholine bronchial challenge test) show change from the baseline level after the immunotherapy?

    Measured: One year

  3. Does the Oral Immunotherapy Have en Effect on Airway Inflammation?

    Does the oral immunotherapy change exhaled nitric oxide levels (measured before and after immunotherapy)

    Measured: One year

Questions about this trial

What is this clinical trial studying?

A study testing Dietary supplement in people with Food Allergy, run by Helsinki University Central Hospital at 1 site in Finland.

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 5 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 11 Feb 2021. 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 Finland. 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?

Yes. Results are posted in the registry (first posted 9 Aug 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?

Number of the Patients That Achieve Higher Tolerance of Allergen With Immunotherapy (time frame: One year). 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 11 Feb 2021.
