You may qualify if…

Male or female patients, between 18 and 55 years of age, inclusive and adolescents between 12 and 17 years of age (after enrollment of 20 adult patients completed the 6 weeks dose escalation period and the safety and tolerability is deemed acceptable).
Physician-diagnosed peanut allergy OR convincing history of objective clinical symptoms consistent with immediate hypersensitivity within 4 hours following known ingestion of peanuts or peanut-containing food AND by the following combined criteria:

Skin Prick Test (SPT) to peanut allergen ≥5 mm compared to saline control.
High-sensitivity C reactive protein (hs-CRP), fibrinogen and neutrophil count within laboratory normal range unless the Investigator considers an abnormality to be clinically irrelevant.
Ability to perform spirometry based on the American Thoracic Society guidelines.
Patient must be trained on the proper use of an injectable epinephrine device and should be able to use it.

You may not qualify if…
