This study is testing a new treatment called Peanut Sublingual Immunotherapy (SLIT) for people allergic to peanuts. **Sublingual** means the tablet is placed under the tongue to help reduce allergy symptoms. The study will take place at several locations and is split into three parts. First, doctors will find the right starting dose for teens and adults. Next, they'll see how people handle increasing doses, and finally, they'll look at how well the treatment works, especially in kids and teens. Participants will take a small peanut dose daily for weeks, which will gradually increase. This treatment includes two different doses and a placebo (a fake pill) for comparison.
- The study lasts several weeks with daily doses and some visits to the clinic.
- Participants will be split into different groups to test the effectiveness of the treatment.
- There's a risk of allergic reactions, so participants need to be monitored closely.
