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.
Food allergy affects about 15 million people in the United States. This includes 6 million children. The current treatment for food allergy is to avoid eating the foods that may cause an allergic reaction and have medications such as epinephrine (adrenaline) in case of a reaction. However, accidental exposures can be extremely difficult to avoid, particularly if you are allergic to multiple foods. The risks of accidental exposures and life-threatening reactions can place a large burden on patients and their families.
Investigators in this study would like to learn if omalizumab injections alone or in combination with multi-allergen oral immunotherapy (OIT) will help people with multiple food allergies eat foods to which they are allergic. Oral means that you will take the food allergen (peanut and 2 other foods to which you are allergic) by mouth. If you are allergic to more than 3 foods, this study will only provide OIT for peanut and 2 other foods.
There are 3 stages to the study:
In Stage 1, investigators would like to learn:
• If omalizumab stops or decreases allergic reactions to peanut and other common food allergens after taking it for a length of time.
Stage 1 will also have an extra part so that 60 participants will receive omalizumab and everyone (the investigators conducting the research and study participants) will know it. This is why it is called the open label extension. This part of the study will assist investigators in learning if receiving omalizumab for a longer time may work better at decreasing allergic reactions.
In Stage 2, investigators would like to learn:
• How a short course of omalizumab combined with Multi-allergen OIT compares with a longer course of omalizumab in decreasing allergic reactions.
In Stage 3, investigators would like to learn:
• If, after participants stop both treatments, will they be able to eat the peanut and the 2 other foods in the form that is normally eaten.
In all stages, investigators would like to learn:
Participation will last up to 56 months (4 years and 8 months).

|---|---|---|---|
| Stage 1:Omalizumab as Monotherapy | Experimental | Eligible participants are randomized to receive omalizumab by subcutaneous injection either every 2 weeks or every 4 weeks for 16 to 20 weeks. The dose administered and the dosing interval are determined by serum total IgE level and body weight (measured before the start of treatment) per the study drug dosing table. After 16 weeks of treatment, each participant will complete double-blind placebo-controlled food challenge (DBPCFCs) to each of their three specific foods to a cumulative dose of 6044 mg protein of each food. Throughout Stage 1, each participant will be instructed to strictly avoid all foods to which they are allergic. The first 60 participants who complete all four DBPCFCs at the end of Stage 1 will participate in the Stage 1 Open Label Extension (OLE).All other participants who complete all four DBPCFCs will move Stage 2 of the study. |
|
| Stage 1: Omalizumab OLE | Experimental | OLE: Open Label Extension, Long-Term Treatment with Omalizumab. Participants will receive 24 weeks of open label omalizumab in accordance with the omalizumab dosing table defined in the study protocol. Omalizumab is administered by subcutaneous injection either every 2 weeks or every 4 weeks for 24 weeks. The dose administered and the dosing interval are determined by serum total IgE level and body weight (measured before the start of treatment) per the study drug dosing table. After 24 weeks of treatment, each participant will complete DBPCFCs to each of their three specific foods to a cumulative dose of 8044 mg protein of each food. Each participant who completes all four DBPCFCs at the end of the Stage 1 OLE will move on to Stage 3 of the study. Throughout Stage 1 OLE, each participant will be instructed to strictly avoid all foods to which they are allergic. |

471 Participants were enrolled during the recruitment period. 289 of the participants that enrolled did not meet the required eligibility criteria and therefore were considered trial screen failures. 180 participants went on to randomize in Stage 1. 2 participants met eligibility criteria after Stage 1 was completed and randomized directly into Stage 2.
Enrollment was open from July 2019 through March 2023.

Eligible participants are randomized to receive placebo for omalizumab by subcutaneous injection either every 2 weeks or every 4 weeks for 16 to 20 weeks. The dose administered and the dosing interval are determined by serum total IgE level and body weight (measured before the start of treatment) per the study drug dosing table.
After 16 weeks of treatment, each participant will complete DBPCFCs to each of their three specific foods to a cumulative dose of 6044 mg protein of each food.
Throughout Stage 1, each participant will be instructed to strictly avoid all foods to which they are allergic.
The first 60 participants who complete all four DBPCFCs at the end of Stage 1 will participate in the Stage 1 OLE. All other participants who complete all four DBPCFCs will move Stage 2 of the study.

| Stage 2: Omalizumab | Experimental | Participants will receive eight weeks of treatment with open label omalizumab in accordance with the omalizumab dosing table specified in the study protocol, administered by subcutaneous injection. The dose administered and the dosing interval are determined by serum total IgE level and body weight (measured before the start of treatment) per the study drug dosing table. After completion of eight weeks of open label omalizumab, participants will be randomized 1:1 to either:
Throughout Stage 2, each participant will be instructed to strictly avoid all foods to which they are allergic. |
|
| Stage 2: Omalizumab-Facilitated OIT | Experimental | 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. |
|
| Stage 2: Omalizumab + Placebo OIT | Experimental | OIT: oral immunotherapy Participants randomized to open label omalizumab + placebo for Multi-allergen OIT for eight weeks, followed by omalizumab + placebo for Multi-allergen OIT for 44 weeks. Throughout Stage 2, each participant will be instructed to strictly avoid all foods to which they are allergic. |

| Stage 3: DBPCFC Based Treatment | Other | 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:
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. |

|
| Placebo for Omalizumab | Drug | Placebo contains the same ingredients as the omalizumab formulation, excluding omalizumab. Placebo will be supplied in pre-filled syringes (PFS). PFS of placebo will be provided to the clinical research units as 75 mg and 150 mg dosage forms. |
|
|
| Multi-Allergen Oral Immunotherapy | Drug | Multi-allergen OIT will be any of the following drug products: peanut, milk, egg, wheat, cashew, hazelnut, and walnut (all food protein flours). A prescription for each participant for the appropriate dose of each of the allergens will be prepared. The pharmacist will compound the appropriate allergens and dispense the Multi-allergen OIT dose in a blinded (masked) fashion. The Clinical Research Unit (CRU) staff will administer food flour to the participant orally in an age-appropriate food vehicle (e.g., applesauce, pudding, etc.). Dosage will be administered according to the study protocol. |
