Active clinical trials for "Peanut Hypersensitivity"

Multicenter, double-blind, randomized, placebo-controlled phase I/II study to determine the safety, tolerability, potential efficacy and dose finding of INP20, an oral immunotherapy in peanut-allergic patients. The overall study design consists of two sequential periods of Part A and Part B. Part A is a dose escalation study in patients from 12 to 65 years old with a history of immediate hypersensitive reaction to peanut protein. Six diferent oral-dose of INP20 will be administered to 6 cohorts of patients once daily for 2 weeks. Part B is a 6-month double-blind, placebo-controlled, randomized and parallel groups study. Patients will be randomized in a 1:1:1 ratio into three (3) different treatment groups, including placebo and the two doses of peanut protein selected from Part A. They will recieve INP20 once daily for 6 months.

The study aims to assess the safety and efficacy of Viaskin Peanut to induce desensitization to peanut in peanut-allergic children 1 to 3 years of age after a 12-month treatment by EPicutaneous ImmunoTherapy (EPIT).

The primary purpose of the protocol is to evaluate the efficacy of a protocol for induction of tolerance to peanut ingestion increasing doses. The secondary purpose is to determine the interest of a prolonged maintenance therapy

Child food allergy represent 6 to 8% of child in industrialised country. Within this allergy, peanuts and egg allergy are one of the most common. Actually when there is a suspicion of food allergy, the OPT is the gold standard for the diagnosis. During the OPT we give increasing doses of the allergen to the patient and evaluate threshold causing a clinical reaction. This test is associated with a risk of strong allergic reaction and need a medical supervision. Standard allergy test, like skin test or specific IgE test, can't be use for the diagnosis of these allergy. Some publications demonstrate that these tests lack sensibility and specificity for child food allergy diagnosis. New tests have to be develop to diagnosis child food allergy without risks. The BAT is a cellular test able to evaluate the basophiles activation by specific allergen in vitro. This test allow us to evaluate more physiologically the sensitization of patients to an allergen. It is already used in drug allergy and it has been evaluated in infant milk allergy in an other clinical trial. In this study we want to evaluate the sensitivity of BAT to the diagnosis of child food allergy compare to the gold standard test OPT. We will evaluate the BAT on 140 children with food allergy and compare this results with the OPT at the same time. If the BAT results can predict the sensitivity of children to food allergen, it could limit the use of the OPT and reduce the risk of this test.

Peanut allergy can be life-threatening. Current diagnostic techniques for peanut allergy have high sensitivity, but not high specificity. This clinical trial will test the validity of a novel blood biomarker (compared with current testing) as a diagnostic predictor of anaphylaxis to peanut.

This is an open-label, follow-up study for subjects who completed the PEPITES study. Subjects will be offered enrollment in this follow-up study to receive Viaskin Peanut 250 μg for 2 additional years if previously on active treatment in the PEPITES study, or for 3 years if previously on placebo in the PEPITES study.

The purpose of this study is to observe the natural course of food allergy, including both the development of peanut allergy in infants at high risk for developing this allergy, and the resolution of both egg and cow's milk allergy.

Open label, cross-over, local pharmacokinetics study of a sublingual film with peanut extract in healthy adults and children

Food allergy is on the rise within the pediatric population. Having food allergy can cause medical, nutritional and psychological issues in those who suffer with it. Although making the appropriate diagnosis of food allergy is very important, properly diagnosing food allergy has been a challenge. Skin prick testing and food-specific IgE testing of the blood can give positive results that are false. Currently, Oral Food Challenges are the best way to diagnose a food allergy. Unfortunately, Oral Food Challenges are time consuming and may not be readily available to suspected food allergy sufferers. This study is designed to examine the effectiveness of an allergy-detecting blood test called IMMULITE 2000 manufactured by the study sponsor, Siemens.

This is a proof of concept study to determine the safety and allergenicity of hypoallergenic peanut product extract as compared to standard peanut extract in an adult population with known peanut allergy. This will be assessed by epicutaneous skin prick testing. The hypothesis is that subjects with previously diagnosed peanut allergy will have less epicutaneous reactions to the hypoallergenic peanut product extract.
