Peanut Oral Induction Tolerance in Peanut's Allergic Teenagers (PITA 3)

July 31, 2026 updated by: University Hospital, Clermont-Ferrand
The primary purpose of the protocol is to evaluate the efficacy of a protocol for induction of tolerance to peanut ingestion increasing doses. The secondary purpose is to determine the interest of a prolonged maintenance therapy
