About this study

Official title: Peanut OIT & Anti-IgE: Peanut Oral Immunotherapy and Anti-IgE Treatment for Peanut Allergy {NIH R21 Combined Peanut Oral Immunotherapy and Anti-IgE: Mechanistic Studies}

The purpose of this study is to determine whether the addition of anti-IgE treatment will make peanut oral immunotherapy safer, more tolerable, and more effective in treating peanut allergy.

Read the detailed description

The goal of this proposal is to produce a new treatment that would benefit subjects who have peanut allergy by lowering the risk of anaphylactic reactions (desensitization), and changing the peanut-specific immune response in subjects who have peanut allergy (tolerance). This project is designed to study if peanut oral immunotherapy (OIT) will desensitize subjects with peanut hypersensitivity by regulating their oral and systemic immune reactivity and cause long-term tolerance. This study will augment other ongoing studies by looking at whether anti-IgE therapy can reduce side effects and allow for an accelerated build up phase. Peanut allergic patients greater than 12 years old will undergo omalizumab (anti-IgE) treatment for 4 months prior to peanut OIT, and they will continue omalizumab until one month after maintenance therapy. Each subject will have an initial desensitization phase over 2 days to a goal of 950 mg of peanut powder followed by a build up phase over 4 months to goal maintenance dose of 8000 mg peanut powder. They will be randomized to continue maintenance for 12 or 24 months. They will then have an oral food challenge (OFC) immediately after stopping peanut OIT to test for desensitization. Four weeks later, off OIT, another food challenge will be done to assess tolerance. Outcome variables of interest include results of the OFCs, pre and post skin tests, CAP-FEIA values and basophil studies. These results will be compared between the starting point and the patient at the end of the study using appropriate statistical analysis.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Peanut Oral ImmunotherapyDrug

    Also called PnOIT

    Peanut flour taken by mouth, given every day. Dose ranges from 0.2mg of peanut flour to 8000mg of peanut flour during the maintenance phase.

  • OmalizumabDrug

    Also called Xolair

    Omalizumab (anti-IgE) will be given for 4 months prior to starting oral immunotherapy. The medication is given as a subcutaneous injection with dose based on total IgE levels and weight at the beginning of the study. This medication is given for a total of 10 months.

Study groups in NCT00932282
Study groupRoleWhat they receive
12 month maintenance of PnOITActive comparatorRandomized subjects who will stay on the maintenance dose of oral peanut immunotherapy (PnOIT) for 12 months. The study has 4 phases: anti-IgE therapy before immunotherapy (Omalizumab), an initial desensitization day(s), a buildup period, and a daily home maintenance phase with a final dose of 8000mg peanut flour (~50% peanut protein). Then all subjects will be randomized to an additional 1 or 2 years (12 or 24 months) of maintenance OIT. An OFC will be performed at the end of the long-term maintenance in all groups.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. The Percentage of Subjects Who Pass the 20gm Peanut Flour (~50% Peanut Protein) Oral Food Challenge 2-4 Weeks After Discontinuing Peanut OIT Therapy

    The primary efficacy outcome of the study is to evaluate whether the addition of anti-IgE therapy using Xolair to peanut oral immunotherapy is able to induce clinical tolerance as measured by passing an oral food challenge to 20 grams of peanut flour, 2-4 weeks after discontinuing peanut OIT therapy

    Measured: approximately 24 or 36 months

Secondary outcomes (4)
  1. The Percentage of Subjects Who Tolerate the Initial Desensitization Day(s) to 950mg of Peanut Flour.

    A secondary efficacy outcome of the study is to evaluate whether the addition of anti-IgE therapy using Xolair to a peanut oral immunotherapy protocol allows for a higher amount of peanut tolerated after the rush desensitization phase, thereby reducing the duration of buildup phase and achieving maintenance dosing more rapidly

    Measured: 4 months

  2. The Percentage of Subjects Who Pass the 20gm Peanut Flour (~50% Peanut Protein) Oral Food Challenge Following the Desensitization Phase of the Study

    A secondary efficacy outcome of the study is to evaluate whether the addition of anti-IgE therapy using Xolair to peanut oral immunotherapy is able to induce clinical desensitization as measured by passing an oral food challenge to 20 grams of peanut flour on the final day of peanut OIT dosing.

    Measured: approximately 24 or 36 months

  3. Incidence of All Serious Adverse Events During the Study

    A secondary safety outcome of the study is to determine the frequency of SAEs during oral immunotherapy in order to assess whether the addition of anti-IgE therapy using Xolair to peanut oral immunotherapy can reduce the number of SAEs that occur during oral immunotherapy when compared to previously published results

    Measured: approximately 24 or 36 months

  4. Incidence of Side Effects During Initial Escalation and Build up Phase of Peanut Oral Immunotherapy

    The primary safety outcome of the study is to determine the frequency of side effects during oral immunotherapy in order to assess whether the addition of anti-IgE therapy using Xolair to peanut oral immunotherapy can reduce the number of allergic symptoms that occur during oral immunotherapy when compared to previously published results

    Measured: approximately 24 or 36 months

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing Peanut Oral Immunotherapy and Omalizumab 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 5 inclusion and 10 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 1 Mar 2018. 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 combined phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 26 Sep 2017). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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 Subjects Who Pass the 20gm Peanut Flour (~50% Peanut Protein) Oral Food Challenge 2-4 Weeks After Discontinuing Peanut OIT Therapy (time frame: approximately 24 or 36 months). 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 1 Mar 2018; AzTrials last refreshed its copy on 7 Nov 2026.
