This study is testing an experimental drug called linvoseltamab combined with another drug named dupilumab. It is for adults with severe food allergies. A food allergy happens when the immune system overreacts to certain foods like peanuts or shellfish. This reaction involves special antibodies called IgE. The research aims to see if linvoseltamab is safe and works well with dupilumab. They will also study any side effects and how much of the drug stays in the blood over time.

• The study involves using dupilumab for at least 12 weeks and might require taking linvoseltamab.
• Participants must use an epinephrine injector for emergencies and may need vaccinations.
• Pregnant women and people with certain health conditions or on certain medications are not eligible.
