MedicalResearch.com: What is the background for this study?
Response: The PEOPLE study is an open-label extension of the Phase III PEPITES trial designed to evaluate the long-term safety, tolerability and efficacy of Viaskin Peanut 250 μg (NCT03013517) in peanut-allergic children ages 4 to 11 years . Participants who completed the 12-month study period of PEPITES were eligible to enroll in PEOPLE. Patients who were randomized to active treatment in PEPITES are eligible to receive up to four additional years of treatment, and those previously receiving placebo are eligible to receive up to five years of treatment.
The current study reports on the 3 year outcomes of children who were initially randomized to receive active treatment in the PEPITES study and completed an additional 2 years of treatment during the PEOPLE study. The study evaluated the eliciting dose (ED) after three years (Month 36) of active treatment using a double-blind, placebo-controlled food challenge (DBPCFC). The starting dose of each challenge was 1 mg of peanut protein and escalated to the highest dose of 2,000 mg peanut protein; possibly repeated once to reach a maximum total cumulative dose of 5,444 mg peanut protein. All participants who reached an ED ≥ 1,000 mg at Month 36 were eligible to continue the study for two additional months without treatment while maintaining a peanut-free diet. A further double-blind placebo-controlled food challenge to determine ED was administered at the end of this period (Month 38).
Additional analyses include exploratory assessments of safety parameters, immune biomarkers such as immunoglobulin G4 (IgG4) and immunoglobulin E (IgE). (more…)
