Filter by:This is a Phase I trial to evaluate the safety and efficacy of oral encapsulated fecal microbiota transplantation (FMT) in the treatment of peanut allergy. In this research the investigators would like to learn more about ways to treat peanut allergies. There is currently no known cure for peanut allergy. The primary aim is to assess safety and tolerability of oral FMT in patients with peanut allergy aged 18-40 years.
The purpose of this study is to determine etokimab safety, tolerability and activity in adult participants with peanut allergy.
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.
Caucasian male and female participants age 18 years of age and older will be enrolled in this study if they have known birch or peanut allergies or known to be non-atopic. Participants will undergo skin testing to confirm their allergies if not completed in the last 12 months. Medications and medical history will be captured with a focus on atopic disorders. Participants will undergo birch and peanut patch testing to assess penetration and if potential correlation exists with filaggrin genotyping and phenotyping. Blood samples will be drawn from participants and DNA isolated for genotyping of null mutations in filaggrin.
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.
Food allergy affects up to 10% of the population. The mainstay of management involves dietary avoidance and provision of rescue medication in the event of an accidental reaction. The Integrated approaches to food allergen and allergy management (iFAAM) collaboration is an EU-funded academic/clinical/industry consortium with the aim to improve allergen risk management including food labelling. Much of this work requires the validation of the minimum 'eliciting dose' for the food-allergic population and how this can be translated into risk management. A number of studies (including iFAAM and the TRACE study - NCT01429896) have assessed the eliciting dose for peanut allergic patients, using food challenges where peanut-allergic individuals are eat incremental doses of peanut under strict medical supervision. In this extension study, peanut-allergic subjects will have undergone (in a cross-over manner) three double-blind, placebo-controlled food challenges to peanut: 1. incremental doses of peanut in a water-continuous matrix; 2. incremental doses of peanut baked into a cookie biscuit; 3. a single dose of peanut in a water-continuous matrix. The differences in eliciting dose, symptom pattern and underlying physiological mechanisms will provide essential data on how the presentation and consumption of peanut affects the amount needed to trigger an allergic reaction, to inform industry and food regulators as to how to best protect the food-allergic population.
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.
