Omalizumab for Peanut Allergy
(OUtMATCH Trial)
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial aims to help individuals with a peanut allergy and allergies to at least two other foods, such as milk or eggs, safely consume these foods without severe reactions. It tests the medication omalizumab, administered as an injection, to determine if it can reduce allergic responses when combined with oral immunotherapy. Participants are divided into groups to receive either omalizumab alone, omalizumab with oral immunotherapy, or a placebo. Those allergic to peanuts and at least two other foods, who frequently experience significant allergic reactions, might be suitable candidates for this trial. As a Phase 3 trial, this study represents the final step before FDA approval, offering participants a chance to contribute to potentially groundbreaking treatment advancements.
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.
Is there any evidence suggesting that this trial's treatments are likely to be safe?
Previous studies have shown that omalizumab is generally safe for treating food allergies. Research indicates no new side effects when using omalizumab for multiple food allergies, and it functions similarly to its use in other conditions, with no severe allergic reactions (anaphylaxis) reported in these studies.
In contrast, multi-allergen oral immunotherapy (OIT) can cause allergic reactions. Some studies have shown a high rate of reactions, although they are often mild. However, OIT is considered relatively safe when administered in a hospital, where assistance is readily available if needed.
In summary, omalizumab is well-tolerated with no new safety concerns, while multi-allergen OIT can lead to allergic reactions, but these are usually manageable in a medical setting.12345Why are researchers excited about this trial's treatments?
Most treatments for peanut allergies involve strict avoidance of peanuts and, in some cases, carrying emergency epinephrine. However, Omalizumab offers a novel approach by targeting and neutralizing IgE, the antibody responsible for allergic reactions, thus potentially reducing the severity of allergic responses. Researchers are excited because Omalizumab is administered through subcutaneous injections, which could be more convenient and less invasive than oral immunotherapy. Additionally, the combination of Omalizumab with multi-allergen oral immunotherapy could enhance tolerance to peanuts and other allergens, offering hope for long-term relief from severe allergic reactions.
What evidence suggests that this trial's treatments could be effective for peanut allergy?
Research has shown that omalizumab can help treat multiple food allergies, including peanut allergies. In this trial, some participants will receive omalizumab as monotherapy, while others will receive a placebo. One study demonstrated that omalizumab allowed patients to tolerate more peanut protein without severe allergic reactions. Specifically, 68% of patients who received omalizumab were protected from moderate to severe allergic symptoms, compared to only 5% of those who received a placebo. Additionally, omalizumab increased the amount of peanut protein many patients could handle by six times. These findings suggest that omalizumab could help people with peanut and other food allergies safely consume more of these foods.46789

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.
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.
