Peanut Epicutaneous Phase II Immunotherapy Clinical Trial
Peanut Epicutaneous Phase II Immunotherapy Clinical Trial
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.
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.
Inclusion Criteria:

 -  Physician-diagnosed peanut allergy OR convincing history of peanut allergy

 -  A skin prick test positive to peanut (wheal diameter ≥3mm greater than the saline
 control) OR detectable peanut specific Immunoglobulin E (IgE) (ImmunoCAP >0.35 kUA/L)

 -  Positive reaction to a cumulative dose of ≤1044 mg peanut protein in the initial
 qualifying Oral Food Challenge (OFC)

 -  Use of an effective method of contraception by females of childbearing potential to
 prevent pregnancy and agree to continue to practice an acceptable method of
 contraception for the duration of their participation in the study

 -  Ability to perform spirometry maneuvers in accordance with the American Thoracic
 Society (ATS) guidelines (1994). Children ages 4-11 years who have documented
 inability to adequately perform spirometry may be enrolled if Peak Expiratory Flow
 (PEF) is >80% of predicted

 -  Provide signed informed consent or assent where indicated

 Exclusion Criteria:

 -  History of anaphylaxis to peanut resulting in hypotension, neurological compromise or
 requiring mechanical ventilation

 -  Participation in a study using an investigational new drug in the last 30 days

 -  Participation in any interventional study for the treatment of food allergy in the
 past 6 months

 -  Pregnancy or lactation

 -  Current or known allergy to the Viaskin Peanut/Placebo patch device or excipients

 -  Current or known allergy to the placebo allergen (oat flour) in oral food challenge
 (OFC)

 -  Currently in a build-up phase of any allergen immunotherapy

 -  Severe or poorly controlled atopic dermatitis or greater than a mild flare of active
 disease at enrollment

 -  Forced Expiratory Volume in 1 Second (FEV1) value <80% predicted or any clinical
 features of moderate or severe persistent asthma baseline severity (as defined by the
 2007 NHLBI Guidelines) and greater than high daily doses of inhaled corticosteroids
 (>500mcg of Fluticasone or equivalent)

 -  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

 -  Asthma requiring >1 hospitalization in the past year for asthma or >1 Emergency
 Department (ED) visit in the past 6 months for asthma

 -  Any previous intubation/mechanical ventilation due to allergies or asthma

 -  Use of omalizumab or other non-traditional forms of allergen immunotherapy or
 immunomodulatory or biologic therapy in the past year

 -  Use of beta-adrenergic blockers, angiotensin-converting enzyme inhibitors,
 angiotensin-receptor blockers, or calcium channel blockers in the past 30 days

 -  Inability to discontinue antihistamines for skin testing and OFC

 -  History of alcohol or drug abuse

 -  History of cardiovascular disease, uncontrolled hypertension, arrhythmias, chronic
 lung disease, active eosinophilic gastrointestinal disease, or other medical
 conditions including immunologic disorders or HIV infection which, in the opinion of
 the investigator, make the subject unsuitable for treatment or at increased risk of
 anaphylaxis or poor outcome
