Oral Immunotherapy for Young Children With Peanut Allergy - Small Children OIT

Study Purpose

Open label study with peanut oral immunotherapy (OIT). Peanut allergic children aged 1-3 years of age will be randomized 2:1 to: 1. Peanut OIT with slow up-dosing (40-60 weeks) up to a maintenance dose of 285 mg daily oral peanut protein or. 2. Control group with peanut allergic children who do not undergo OIT. 3. In addition, a group of healthy children without allergic diseases will be included in the study. The primary outcome is tolerance to at least 750 mg peanut protein at a challenge after 3 years and sustained unresponsiveness (i.e. tolerance) to 750 mg peanut protein after 3 years of OIT followed by 4 weeks of avoidance. Efficacy and safety will be compared between group 1 and 2. Group 3 is a control group for analyses of immunological markers.

Recruitment Criteria

Accepts Healthy Volunteers

Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms

Study Type

An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.

An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.

Searching Both is inclusive of interventional and observational studies.

Eligible Ages 1 Year - 3 Years
Gender All

Trial Details

Trial ID:

This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.


Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.

Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.

Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.

Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.

Peanut Allergy
Additional Details

Problem: Today there is no clinically available treatment for peanut allergy. Oral Immunotherapy (OIT) studies have shown promising results, particularly in younger children (<4 years). Intervention: Peanut OIT in children aged 1-3 years with peanut allergy (clinical symptoms at peanut challenge and IgE >0.1 kU /l to peanut and/or Ara h 2). Comparison: Three groups are compared. Peanut allergic children are randomized 2:1 to group 1 (active OIT) or group 2 (control). Group 3 consists of age-matched healthy controls: Group 1; Children with peanut allergy receiving peanut OIT, slow up-dosing, 40-60 weeks, until the maintenance dose 285 mg peanut protein. Three years' treatment. (n=50 patients) Group 2; Age-matched children with peanut allergy who do not undergo OIT peanut. Peanut challenge one and three years after inclusion. (n=25 patients) Group 3; Healthy, non-allergic, age-matched children. No challenges are performed in this group. (n=30 patients) Group 4; Children not reacting at the baseline peanut challenge (n=X patients) Inclusion of study subjects: A review of samples sent to the Karolinska University Laboratory for IgE-ab responses to peanut/Ara h 2 for children in the Stockholm area aged 1-3 years is used for identification of potential participants to whom a letter is sent with information about the study. The families are randomized 2:1 to OIT or control group, group 1 or group 2. Children without allergies, healthy Controls (group 3), will be identified through the day surgery at Astrid Lindgren's Children's Hospital. If children are included in the study but they do not not react at the baseline peanutchallenge, they will not have any intervention (are not eligible to randomisation) and will have a follow-up after 1+3 years (without peanut challenges), group 4. Outcomes: The primary outcome is defined as sustained unresponsiveness to 750 mg peanut protein (cumulative dose) at an open oral peanut challenge after 3 years of OIT+4 weeks of avoidance (group 1 and 2). Secondary outcomes are adverse events among peanut allergic children with/without OIT treatment (group 1 and 2), and changes in quality of life parameters and immunological markers (group, 1, 2, 3).

Arms & Interventions


Active Comparator: OIT peanut

Children with peanut allergy receiving peanut OIT. Peanut challenge are done before randomization and one and three years after inclusion. n=50 patients

No Intervention: Peanut avoidance

Children with peanut allergy not undergoing OIT peanut. Peanut challenge are done Before randomization and one and three years after inclusion. n=25 patients

No Intervention: Healthy controls

Control Group with non-allergic, age-matched children. No challenges are performed in this group. n=30 patients

No Intervention: Children not reacting at the baseline peanut challenge

Peanut-allergic children not reacting at the baseline peanut challenge, will not be eligible for randomisation. They will have a clinical visit after 1+3 years. No more challenges in this group. n=X patients


Dietary Supplement: - Peanut (bamba)
