Could a shot help people with multiple food allergies eat peanuts safely?

NCT ID NCT03881696

First seen Jun 26, 2026 · Last updated Jun 26, 2026

Summary

This study tested whether omalizumab (Xolair), an allergy drug, helps people with peanut and at least two other food allergies eat those foods without severe reactions. Over 470 participants aged 1 to 55 received omalizumab or a placebo, and some also got oral immunotherapy. The goal was to see if they could tolerate a dose of peanut protein without symptoms.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance

omalizumab (Xolair) and multi-allergen oral immunotherapy

What this could lead to

If successful, this could provide a new treatment option to help people with multiple food allergies tolerate small amounts of allergenic foods without severe reactions.

What could go wrong

This is a completed phase 3 trial, but results may not apply to all food allergies or ages. Omalizumab is not a cure and requires ongoing injections; risks include allergic reactions and side effects from the drug.
