Efficiency And Tolerance Of Hazelnut Oral Immunotherapy Protocol In Hazelnut Allergic Children (ENOIME)

September 10, 2021 updated by: Hospices Civils de Lyon

Clinic And Biologic Efficiency And Tolerance Of Oral Immunotherapy Protocol In Hazelnut Allergic Children

Prevalence of food allergy in the world has been inscreasing in recent years. Among nut allergy, hazelnut allergy is the most widespread in Europe and particularly in France. The current treatment for hazelnut allergy is based on eviction and wearing of an emergency kit with adrenaline auto-injector pens, to be used in the event of severe anaphylactic reaction. Oral immunotherapy (OIT) is a treatment that is now increasingly being offered as an alternatice to eviction. There are few published data concerning hazelnut OIT in Europe, where its consumption is nevertheless very high.

The main objective of our study is to evaluate the clinical efficacy of the hazelnut OIT protocol, implemented since 2015 in the pneumology and allergology-paediatric department of the Mother and Child Hospital in Bron, in hazelnut allergic children under 18 years old.

The secondary objectives will be to evaluate the biological efficacy and clinical tolerance of the protocol.

The study is retrospective and observational, and is based on the collection of medical data from patient records.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
the proportion of patients in maintenance phase at the one-year consultation
Time Frame: at the one-year consultation
Patients are in maintenance phase at the end of the up-dosing phase and take regularly a quantity of hazelnut, usually superior to 800 mg, considered an acceptable protective dose
at the one-year consultation

Study Major Dates

Study Start (ACTUAL)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
March 1, 2021

Primary Completion (ACTUAL)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
