Understanding How the Immune System Responds to Viruses in Peanut Allergic Children Undergoing Peanut Oral Immunotherapy
A study testing Peanut flour in people with Peanut Allergy, run by University of Texas Southwestern Medical Center at 1 site in United States.
Trial summary
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.

About this study
Official title: Dendritic Cell Responses to Viral Stimulation in Peanut Allergic Subjects Undergoing Peanut Oral Immunotherapy
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.
Read the detailed description
Peanut allergy is known to cause severe anaphylactic reactions. Compared with other food allergies it tends to be more persistent and also its prevalence seems to be rising. Currently there is no proven treatment other than strict avoidance. We are attempting to decrease the risk of anaphylaxis on accidental ingestion by desensitizing subjects to peanut using peanut oral immunotherapy (OIT). We are also studying the effect of viral infections on the immune system in children receiving peanut OIT.
Children ages three to sixteen years of age with peanut allergy will be given peanut OIT. Twenty-five subjects will also be recruited as controls. These subjects will not receive any peanut or placebo but only have skin prick testing and lab work in addition to a history and physical exam. Active subjects will undergo a double-blind food challenge at entry to verify that they are allergic to peanuts. If allergic, they will then have modified rush immunotherapy on the first day and then increase the doses at least every two weeks up to a maintenance dose of 4 grams (equivalent to about 13 peanuts). Doses will be taken daily at home except for dose increases which will be done at Children's Medical Center. Outcome variables of interest include response to double-blind placebo controlled food challenge, skin prick testing, peanut specific IgE, and adverse events. These results will be compared between the start and end of peanut OIT using appropriate statistical analysis.

Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
We will measure changes in the immune system on a molecular level affected by viral infections in peanut allergic children undergoing peanut OIT. (time frame: 5 years). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT01074840, which also lists 2 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 3 Dec 2014.
