Active clinical trials for "Peanut Hypersensitivity"

The purpose of this trial is to study the safety of rescue peanut oral immunotherapy followed by the introduction of dietary peanut for patients with peanut allergy who have lost desensitization during a peanut immunotherapy trial.

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.

Many children who are allergic to peanuts do not outgrow their allergy and have very severe allergic reactions called anaphylaxis. Symptoms of anaphylaxis include difficulty breathing, decreased blood pressure, hives, and lip or throat swelling after exposure to an allergen. A severe allergic reaction can lead to death if not treated appropriately. The purpose of this study is to find out if there is a way to treat children with peanut allergy to help lower the risk of severe allergic reactions and also cause them to lose their allergy to peanuts. The approach that will used for this study is a process called "desensitization". Oral immunotherapy involves eating gradually increasing amounts of a food over several months. This is a research study because at this time peanut oral immunotherapy (OIT) is investigational. Peanut OIT (study drug) is investigational because it is not currently approved for clinical use by the Food and Drug Administration. There are no alternative safe and effective treatments for peanut induced allergic reactions other than peanut avoidance and treatment with medications.

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.

Peanut allergy is increasingly common, especially in countries such as UK and Australia. There is currently no accepted routine clinical therapy to cure peanut allergy. Recently studies have looked at desensitising people with peanut allergy by giving them small daily doses of roasted peanut. Although this therapy works for some people, its effects are not generally long lasting and it is associated with many side effects during protocol, resulting in a significant rate of drop-outs. Pilot data suggests that boiled peanut is less immunogenic than roasted peanut, and may therefore provide a safer way of inducing desensitisation in patients who are allergic to roasted peanut, by first inducing tolerance to boiled peanut. Study hypothesis: Increasing doses of boiled peanut can induce desensitisation to roasted peanut, in peanut-allergic individuals.

Open pilot study of peanut oral immunotherapy in 22 children with peanut allergy

The purpose of this study is to determine if mucosal peanut immunotherapy will make subjects who have peanut allergy less allergic and induce changes in their immune system.

The purpose of this study is to find out if there is a way to treat children with peanut allergy to help lower the risk of severe allergic reactions and also cause them to lose their allergy to peanuts and to understand what happens to their immune systems when they have viral infections while on therapy. The approach we will use to treat peanut allergy in this study is a process called desensitization. We think that children with a peanut allergy receiving peanut oral immunotherapy will be able to eat more peanuts without having a reaction by the end of the study than they could eat at the beginning. We also think that we will be able to measure changes in their immune system and their immune system's response to viruses while they are on therapy.

This is a Phase IIb, multicenter, open-label study available to active (Xolair) and control (placebo) subjects who have completed their final visit (or early termination visit, if applicable) for Study Q2788g, who meet the eligibility criteria of this study, and who provide consent to participate in this study.

This is a phase 1, multi-center, randomized, double-blind, placebo-controlled study in adult participants with peanut allergy. Participants will be randomized in a 3:1 ratio to receive either an escalating dose of INT301 or placebo. The treatment group will be blinded to the investigator, participants, and the Intrommune study team.
