Filter by:This study evaluates the safety of Viaskin Peanut 250 mcg in the treatment of peanut allergy in children from 4 to 11 years of age. Subjects will receive either Viaskin Peanut 250 mcg or a placebo for a period of 6 months, after which all subjects will be receiving the active treatment up to a period of 3 years under active treatment.
The purpose of this study is to evaluate the safety and tolerability of ASP0892 after intradermal or intramuscular injection in adults with peanut allergy.
This project intends the analysis and profiling of specific antibodies against major peanut allergens in peanut allergic individuals and molecular cloning of human antibodies against major peanut allergens.
This protocol is designed to better characterize a sub-population of peanut sensitized individuals who may be non-allergic, despite significant sensitization, or who may be allergic, but at high threshold doses. By specifically targeting participants who met the initial screening criteria of the active adult PN OIT study, Protocol 2012p002153 / AADCRC MGH-004 (MGH-004), but failed to react during the pre-treatment 443 mg challenge to peanut, the investigators anticipate that the investigators will identify individuals who have become spontaneously tolerant, despite persistent sensitization. The investigators might also find that clinical sensitivity persists but only with higher thresholds, or that sensitivity has increased (or is variable) since the previous allergen exposure. By repeating DBPCFCs through to a full serving dose (7.4 gram), the investigators will distinguish participants who react only at higher doses from those who were not truly peanut allergic, address whether their sensitivity has changed, and have the opportunity to further investigate their immune response to peanut allergen.
The PEPITES study evaluates the efficacy and safety of Viaskin Peanut 250 µg peanut protein to induce desensitization to peanut in peanut-allergic children 4 through 11 years of age after a 12-month treatment by epicutaneous immunotherapy (EPIT).
The purpose of this study is to demonstrate the efficacy and safety of AR101 through reduction in clinical reactivity to peanut allergen in peanut-allergic children and adults.
Severe peanut allergy is different from other allergic reactions because it can lead to fatal reactions and is an invisible disability. There is no cure today. The purpose of this study is to treat children and adolescents with severe peanut allergy with oral immunotherapy with peanuts under the protection of anti-IgE (immunoglobulin E) antibodies (omalizumab), and thereby inducing tolerance to peanuts. The treatment will be monitored by basophil cell stimulation (CD-sens).
Primary Objective: To determine if 36 months of peanut SLIT as an early intervention in subjects ages 1 to 4 years induces clinical desensitization. The primary outcome of this objective will be a statistically significant difference in challenge scores between the treatment group versus the placebo group during DBPCFC (Double blind placebo controlled food challenge) performed after 36 months of peanut SLIT (desensitization). Challenge scores are measured by the amount of peanut protein participants are able to ingest successfully without symptoms of an allergic reaction. [Time Frame: Baseline, 36 months] Secondary Objectives: A secondary outcome of this objective will be a statistically significant difference in the challenge score of the treatment group versus the placebo group during the DBPCFC performed 3 months after discontinuing therapy (tolerance). To examine the change in immune parameters associated with peanut SLIT and the development of clinical tolerance. Through this objective, the investigators will seek to understand the molecular processes by which SLIT affects the immune system through evaluation of immune mechanisms in relationship to clinical findings of desensitization and tolerance. The investigators will delineate the impact of peanut SLIT on the subsequent cellular and humoral responses to peanut protein. [Time Frame: Baseline, 39 months]
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.
