Trial Summary

What is the purpose of this trial?

This study is a multi-center, randomized, double-blind, placebo-controlled study in participants 1 to less than 56 years of age who are allergic to peanut and at least two other foods (including milk, egg, wheat, cashew, hazelnut, or walnut). While each participant may be allergic to more than two other foods, the primary endpoint/outcome in this study will only be assessed in peanut and two other foods for each participant. The primary objective of the study is to compare the ability to consume foods without dose-limiting symptoms during a double-blind placebo-controlled food challenge (DBPCFC), after treatment with either omalizumab or placebo for omalizumab.

Will I have to stop taking my current medications?

The trial requires that you stop taking certain medications, such as oral, intramuscular, or intravenous corticosteroids, tricyclic antidepressants, beta-blockers, and monoclonal antibody therapies like omalizumab, within specific timeframes before screening. Additionally, you must be able to discontinue antihistamines for the required washout periods for skin prick tests or oral food challenges.

What data supports the effectiveness of the treatment Omalizumab for Peanut Allergy?

Research shows that using omalizumab (a medication that reduces allergic reactions) alongside peanut oral immunotherapy (a treatment to build tolerance to peanuts) can help children with peanut allergies become desensitized more quickly and safely. Studies have demonstrated that this combination can lead to successful desensitization to multiple food allergens over a period of weeks. ^{1 2 3 4 5}

Is omalizumab safe for use in humans?

Omalizumab is generally considered safe and is FDA-approved for allergic asthma. It has been used in clinical trials for food allergies, allowing higher doses of immunotherapy with fewer adverse reactions. However, large multi-center trials are needed to confirm its safety and effectiveness for food allergies. ^{1 6 7 8 9}

How does the drug omalizumab differ from other treatments for peanut allergy?

Omalizumab is unique because it is an anti-IgE medication that helps reduce allergic reactions by binding to IgE antibodies, allowing for faster and higher dosing of peanut oral immunotherapy, which can increase tolerance to peanuts in allergic individuals. ^{1 4 5 7 10}

Participant Groups

Group I: Stage 3: DBPCFC Based Treatment Experimental Treatment 1 Intervention

DBPCFC Based Treatment-Long-term Follow-up Treatment Plan for Peanut and Each of the Two Other Participant-Specific Foods. Upon completion of the DBPCFCs at the end of Stage 1 OLE or Stage 2, each participant will receive a separate treatment plan for peanut and each of the two other participant-specific foods based on the results of the DBPCFCs. A treatment plan will include instructions for one of the following: * Long-term follow-up with dietary consumption of a food; * Long-term follow-up with avoidance of a food; or * Rescue OIT for a food. The treatment plan for each food may change throughout Stage 3 depending on a participant's response to treatment. Once a participant enters Stage 3, the participant will have a minimum of 12 months follow-up until at least December 2022. Note: Participants will be instructed to strictly avoid a food if they receive rescue OIT for the food during Stage 3.

Group II: Stage 2: Omalizumab-Facilitated OIT Experimental Treatment 2 Interventions

OIT: oral immunotherapy-Omalizumab as Adjunct Therapy to Multi-Allergen Oral Immunotherapy Participants randomized to open label omalizumab + Multi-allergen OIT for eight weeks, followed by placebo for omalizumab + Multi-allergen OIT for 44 weeks. Throughout Stage 2, each participant will be instructed to strictly avoid all foods to which they are allergic.

Group III: Stage 2: Omalizumab + Placebo OIT Experimental Treatment 2 Interventions

Findings from Research

Omalizumab, when used alongside food allergen oral immunotherapy (OIT) for allergies like milk and peanuts, can help patients reach maintenance dosing faster and reduce adverse events, although serious side effects can still occur.

There is a risk of increased allergic reactivity after stopping omalizumab, and many patients have discontinued treatment, highlighting the need for more research to improve safety and identify the best candidates for this therapy.

Omalizumab as an adjuvant in food allergen immunotherapy. Dantzer, JA., Wood, RA.[2021]

In a phase 1 trial involving 15 participants (5 healthy adults and 10 peanut-allergic adults), the rectal administration of the modified peanut protein vaccine EMP-123 showed no significant adverse effects in healthy volunteers, but 50% of peanut-allergic subjects experienced adverse reactions, including severe allergic reactions in 20%.

Despite the adverse reactions, the treatment led to significant reductions in peanut skin test responses and basophil activation, indicating some immunologic effects, although no significant changes were observed in total IgE or peanut-specific IgE levels.

Omalizumab, an FDA-approved monoclonal antibody for allergic asthma, works by binding to IgE, which may also help patients with food allergies by allowing them to tolerate higher amounts of allergens during treatment.

In clinical trials, omalizumab has shown promise as an adjunct therapy in food allergy immunotherapy, enabling patients to receive higher doses more quickly, but further large-scale studies are needed to confirm its efficacy and identify the best candidates for treatment.

Use of omalizumab in the treatment of food allergy and anaphylaxis. Lieberman, JA., Chehade, M.[2021]

In a study of 15 children with severe asthma, treatment with omalizumab significantly increased food allergen thresholds, allowing 70.4% of subjects to tolerate previously problematic foods without oral immunotherapy.

The quality of life for patients improved markedly, as indicated by a significant increase in Pediatric Quality of Life Inventory scores, alongside a dramatic reduction in allergic reactions from 47 to just 2 over the treatment period.
