Overview
Brief Summary
Food allergy occurs when the immune system reacts against foods. The immune system is the part of the body that protects us from illness and germs, but it can also cause allergies. Peanut allergy occurs in 1 - 2% of people in the United States and other Western countries. There is proof that allergy to peanut is increasing. Allergic reactions to peanut can be severe and life threatening. The only way that you can prevent an allergic reaction is to avoid exposure to peanuts. However, peanut proteins are found in a variety of foods and people can be accidently exposed to peanut proteins. Treatment for accidental exposure include antihistamines (medications like Benadryl), and injectable epinephrine (adrenalin) which must be carried at all times. DBV Technologies has developed an epicutaneous delivery system, a patch that puts the peanut protein on the skin.
Detailed Description
This study will evaluate whether peanut epicutaneous immunotherapy can protect individuals who are allergic to peanuts from having severe allergic reactions, when accidentally exposed to peanuts. The study also looks at the safety of the treatment and the effects it has on the immune system.

- •Use of steroid medications in the following manners: history of daily oral steroid dosing for \>1 month during the past year, or burst or steroid course in the past 3 months, or \>1 burst oral steroid course in the past year or use of oral or parenteral steroids for a non-asthma indication within the past 30 days
Outcomes
Primary Outcomes
Percentage of Subjects With a Successful Treatment Response
Time Frame: Week 52
Treatment response is defined as a subject who can either (a) successfully consume a cumulative dose of peanut protein equal to or greater than 5044 mg or (b) successfully consume at least a 10-fold increase in peanut protein at the Week 52 oral food challenge (OFC), when compared to the cumulative successfully consumed dose at the baseline OFC.
Secondary Outcomes
- Percentage of Subjects Desensitized to Peanut Protein(Week 130 (Month 30))
- Percentage of Subjects Who Can Successfully Consume 1044 mg or 5044 mg Peanut Protein(Week 130 (Month 30))
- Percentage of Desensitized Subjects in the Active Treatment Arms as Measured by 5044 mg Peanut Protein Oral Food Challenge (OFC)(Week 52)
- Average Successfully Consumed Dose as Measured by 5044 mg Peanut Protein Oral Food Challenge (OFC)(Week 52)
- Percentage of Subjects Who Successfully Complete the Dosing Regimen With no More Than Mild Symptoms Related to Peanut Patch Dosing After 30 Months of Therapy(Month 30 (Week 130))
- Percentage of Subjects Who Pass an OFC to 5044 mg of Peanut Protein Followed by an Open Feeding of Peanut Butter After 8 Weeks or 20 Weeks of Discontinuation of Dosing Subsequent to Passing the Week 130 Oral Food Challenge (OFC)(8 and 20 weeks after the Week 130 (Month 30) OFC)
- Percentage of Subjects With Adverse Events Related to Therapy Through Week 52 and Through 30 Months(Week 52 and Month 30 (Week 130))
