About this study
Official title: Pilot Study: Oral Peanut Immunotherapy for Peanut Allergic Patients
This is a study to determine if peanut oral immunotherapy (OIT) would desensitize or tolerize peanut allergic patients to peanuts in order prevent peanut allergic reactions.
Read the detailed description
The goal of this proposal is to develop peanut OIT for patients with peanut allergic reactions. This approach is designed to utilize our extensive knowledge of the allergens involved in peanut hypersensitivity to devise an immunotherapeutic approach that would lower the risk of anaphylactic reactions and would down regulate peanut-specific T cells in peanut-allergic patients. Previous attempts to utilize peanut-specific immunotherapy (IT) have been unsuccessful primarily because of the side effects of therapy.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Peanut proteinDrug
Also called Peanut OIT
Subjects will receive increasing amounts of peanut protein over the modified rush phase and the build-up phase of the protocol. Once the subject reaches the maintenance phase of the study, they will remain on that dose until they reach the oral food challenges at the end of the study.
| Study group | Role | What they receive |
|---|---|---|
| Peanut protein | Experimental | Subjects to receive varying amounts of peanut protein as peanut oral immunotherapy. Receives: Drug: Peanut protein |
What is being measured
The primary outcome is the main question the study is designed to answer.
The percentage of peanut-allergic patients achieving clinical desensitization to peanut, assessed after up to five years of OIT.
Clinical desensitization will be measured with an oral food challenge (OFC) to peanut conducted while on OIT therapy.
Measured: 2 to 5 years
Clinical desensitization will be measured with an oral peanut challenge conducted while on OIT therapy.
Clinical tolerance will be measured with an oral peanut challenge conducted four weeks after discontinuing OIT.
Measured: 2 to 5 years
Secondary outcomes (2)
Changes in number of antigen-specific lymphocytes.
The investigators will examine the role of OIT on peanut-specific T cell responses by enumerating specific T cell subsets, including T regulatory cells, pre- and post-treatment.
Measured: 2 to 5 years
Changes in function of antigen-specific lymphocytes.
The investigators will examine the role of OIT on peanut-specific T cell responses by analyzing cell signaling, gene expression, and cytokine production, pre- and post-treatment.
Measured: 2-5 years

Questions about this trial
What is this clinical trial studying?
A Early Phase 1 study testing Peanut protein in people with Peanut Hypersensitivity, run by University of North Carolina, Chapel Hill at 1 site in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 3 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 25 Jun 2015. Status can change between updates, so confirm with the study contact before making plans.
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.
What does this phase mean?
Early Phase 1 (sometimes called Phase 0) studies give a very small amount of a treatment to a few people, mainly to see how the body handles it.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
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?
The percentage of peanut-allergic patients achieving clinical desensitization to peanut, assessed after up to five years of OIT. (time frame: 2 to 5 years). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
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 25 Jun 2015; AzTrials last refreshed its copy on 6 Nov 2026.
