Yeah OIT will slowly “train” your immune system to not react to increasing amounts of an allergen. This is literally a monoclonal antibody that binds to free IgE antibodies so that there will be fewer of them around if you’re exposed to an allergen.
It seems much more well suited for its originally approved uses of allergic asthma and nasal polyps (which are caused by recurrent allergic inflammatory processes involved in sinusitis/rhinitis) than it would be for food allergies.
