Filter by:This is a multi-center, open-label, follow-on study to gather additional information on the safety and tolerability of oral desensitization with CPNA in the subjects who participated in ARC001.
This pilot study is will examine the pathways involved in allergic response, primarily in food allergy; specifically peanut allergy. We will also study non-allergic donors as well as patients with atopic disorders, primarily as control subjects. We believe that this study will lead to discovery of significant pathways involved in the allergic pathway that can be explored in more detail during follow-up studies in order to address mechanistic questions that cannot be answered in a pilot trial. We believe that such a pilot study represents the ideal approach to identify effective therapeutic interventions and to simultaneously better understand the underlying mechanistic properties involved in the allergy cascade. We think that this study forms the basis for a novel avenue of research into the pathogenesis of allergic pathways, a disease that is still associated with significant morbidity and mortality.
Currently, there is no effective causal treatment for peanut allergy. A chemically modified, aluminium hydroxide adsorbed peanut extract (HAL-MPE1) for subcutaneous administration has been developed. Results from in vitro and in vivo preclinical studies demonstrate the immunotherapeutic potential of HAL-MPE1. Therefore, a phase I, single-centre clinical trial has been designed to assess the safety and tolerability of HAL-MPE1 in peanut allergic patients.
Determine whether peanut oral immunotherapy (OIT) induces clinical tolerance as assessed after the initial 3 month avoidance period Secondary Objectives: - Identify the basic immune mechanisms which can explain the differences in the effects of OIT in desensitized vs. tolerant individuals. - Determine whether immune monitoring measurements reflecting underlying mechanisms during OIT can be used to predict responses to OIT in individual subjects and, ultimately, to improve the safety and efficacy outcomes in peanut OIT protocols.
This is a multi-center, randomized, double-blind placebo controlled study of efficacy and safety of characterized peanut oral immunotherapy in peanut allergic individuals.
The objectives of this open-label follow-up study for subjects who previously were randomized and have completed the VIPES study for the treatment of peanut allergy, are: - To assess the efficacy of Viaskin Peanut after up to 36 months of treatment. - To evaluate the safety of long-term treatment with Viaskin Peanut. - To evaluate sustained unresponsiveness to peanut after a period of 2 months without treatment in subjects showing desensitization to peanut after treatment with Viaskin Peanut.
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.
The investigators will perform a double blind, placebo controlled clinical trial with Xolair (omalizumab) at four centers to safely and rapidly desensitize patients with severe peanut allergy. The investigators will determine if pretreatment with anti-IgE mAb (Xolair/omalizumab) can greatly reduce allergic reactions and allow for faster and safer desensitization.
The unifying objective of this project is to determine whether peanut oral immunotherapy (PN OIT) induced clinical tolerance in the context of food allergy is significantly associated with the expansion of a specific regulatory T cell subset (CD45RA- CD25++ FoxP3++) that is thought to be inducible in the gut-associated lymphoid compartment and associated with immunological tolerance. The hypothesis of the study is that the induction of Treg cells will be associated with clinical tolerance. The investigators will measure the change from baseline of induced Treg cells as a frequency of total CD4 T cells during active treatment and compare that between participants who achieve significant clinical tolerance (Tolerance and Partial Tolerance Groups as defined below) and those who do not (Treatment Failure Group).
The objectives of this dose-finding study for the treatment of peanut allergy are: - To determine the efficacy of 3 doses of Viaskin Peanut (50 mcg ,100 mcg and 250 mcg peanut protein per patch) to significantly desensitize peanut-allergic subjects to peanut after 12 months of treatment. - To evaluate the safety of a long-term treatment with Viaskin Peanut.
