This study tests a new treatment called RPT904 for people with food allergies. Food allergies happen when your body reacts strongly to certain foods. This study will test RPT904, a monoclonal antibody, which is a type of medicine made to help the immune system fight allergies. Participants aged between 12 and 55, who are allergic to peanuts, milk, eggs, cashews, or walnuts, may join. The study lasts about 68 to 74 weeks, which is over a year. Participants will either receive RPT904 or a placebo, which is a harmless pill with no medicine, every 8 to 12 weeks. They’ll have regular visits every 2-6 weeks to see how the treatment is working and monitor any side effects.
