Peanut allergy is a growing public health problem in developed countries with more and more hospitalizations for anaphylaxis. It has been determined that sensitization to certain peanut proteins such as rAra h 2, is predictive of allergy and could predict the severity of reaction (anaphylaxis) during Oral food challenges (OFC). So far, consensual threshold for cutaneous test and IgE as predictor in the positivity of OFC have not been determined. Identification of reactive doses for OFC and phenotype of patients would help to personalize management of patients subgroups, with an optimal security.
The HYPONUT product was previously validated in a laboratory setting ("Procédé de préparation d'aliment hypoallergénique", n° FR1250977) on 2012. A international patent was then obtained on 2013. Through the present study, the investigators would like to prove that the hypoallergenicity of the product is sustained in a clinical setting. Patients allergic to peanuts currently undergo in vivo tests to confirm their allergy: skin prick tests, and oral food challenges. In vitro tests are also performed (i.e. IgE levels for peanut and peanut components). The follow-up of patients consists in regular yearly or semestral evaluations. During one of these evaluation, the investigators will skin tests patients with the hyponut product to verify if they are sensitized to this last one as well. When skin tests will be negative, the investigators will propose to patients to take some of the product to verify its tolerability as well.
The primary objective of the study is to assess the tolerability of peanut protein in pediatric patients (6-17 years old) treated with dupilumab monotherapy, in which tolerability is defined as the proportion of patients who safely pass a double-blind placebo-controlled food challenge (DBPCFC) at week 24. The secondary objectives are: - To determine whether dupilumab treatment improves peanut tolerability, defined as a change in the cumulative tolerated dose (log transformed) of peanut protein during a DBPCFC - To evaluate the safety and tolerability of dupilumab treatment in peanut allergic patients - To evaluate the effects of dupilumab treatment on the levels of peanut-specific Immunoglobulin E (IgE) - To evaluate the treatment effect of dupilumab on the average wheal size after a titrated skin prick test (SPT), as measured by area under curve (AUC) of the average wheal size induced by peanut extract at different concentrations - To assess the incidence of treatment-emergent anti-drug antibodies (ADA) to dupilumab in patients over time
The purpose of this study is to evaluate the safety and tolerability of ASP0892 after intradermal (ID) injection in adolescent participants with peanut allergy.
The purpose of this study is to determine the efficacy and safety of AR101 in peanut-allergic children aged 1 to < 4 years.
To compare the HRQOL of AR101 characterized oral desensitization immunotherapy (CODIT™) in combination with standard of care (peanut avoidance, education) versus standard of care alone in peanut-allergic subjects aged 4 to 17 years.
Primary objective is to assess whether dupilumab as adjunct to AR101 compared to placebo improves desensitization at the completion of up-dosing, defined as an increase in the proportion of participants who pass a post up-dosing double-blind placebo-controlled food challenge (DBPCFC) at visit 16. Secondary objectives are: - To assess whether dupilumab as adjunct to AR101 compared to placebo improves desensitization at the completion of up-dosing, defined as an increase in the cumulative tolerated dose (log transformed) of peanut protein during a post up-dosing DBPCFC at visit 16 - To assess whether dupilumab as (indefinite [continuously]) adjunct to AR101 compared to placebo maintains desensitization, defined as an increase in the proportion of participants who pass a post maintenance DBPCFC at visit 22 - To assess whether dupilumab as (limited [previously]) adjunct to AR101 compared to placebo maintains desensitization, defined as an increase in the proportion of participants who pass a post maintenance DBPCFC at visit 22 - To evaluate the safety and tolerability of dupilumab as adjunct to AR101 compared to placebo - To assess the effect of dupilumab (compared to placebo) as adjunct to AR101 on the change in peanut-specific Immunoglobulin E (sIgE), Immunoglobulin G (IgG), Immunoglobulin G4 (IgG4), and peanut-specific IgG4/IgE ratio - To assess if dupilumab increases the tolerability of AR101 as measured by the daily symptoms (electronic diary [e-diary]) during the up-dosing phase
This protocol will help better define whether patients with peanut and/or tree nut food allergy can tolerate traces in products with precautionary allergen labelling.
Food allergy (FA) is a serious public health concern that causes potentially-life threatening reactions in affected patients. The prevalence of food allergy in the United States (U.S.) has increased substantially and now affects 15 million patients:4-8% of children (6 million children, 30% with multiple food allergies) and about 9% of adults. This is a prospective Phase 2, single-center, multi-allergen OIT study in participants with proven allergies to 2 or 3 different foods in which one must be a peanut. The total of participants in the clinical study will be 110, ages 4 to 55 years with a history of multiple food allergies of 2 to 3 different foods including peanut. Allergy will be confirmed by FA-specific IgE levels and positive skin prick test (SPT). Enrolled participants must be positive during the Double-blind Placebo-controlled Food challenge (DBPCFC) at or before the 300 mg (444 mg cumulative) dosing level of FA proteins.
