Summary

This was a 52-week, Phase 3 multi-center, randomized, double-blind and placebo-controlled study to assess the safety and clinical efficacy of two dosing regimens of ligelizumab (240 mg and 120 mg) SC q4w (subcutaneous injection every 4 weeks) in participants with a medically confirmed diagnosis of Immunoglobulin E (IgE) mediated peanut allergy.

Detailed description

Participants were randomized to ligelizumab 240 mg, ligelizumab 120 mg, or placebo (5 treatment arms, randomization ratio of 2:2:2:2:1) for the double-blind placebo-controlled treatment period (up to Week 12). Participants initially assigned to the 8-week placebo arms received the first dose of blinded ligelizumab treatment at the Week 8 visit. Participants initially assigned to the 16-week placebo arm received the last dose of placebo before the Double Blind Placebo Controlled Food Challenge (DBPCFC) at Week 12 and the first dose of blinded ligelizumab treatment at the Week 16 visit. At the start of the study, recruitment was restricted to 12-55-year-old participants. After approximately 60 adolescent participants (defined as 12-17 yrs of age) had completed all Week 12 assessments, an interim analysis (IA1) on Pharmacokinetics (PK) and selected Pharmacodynamics (PD) data (total IgE and basophil bound High affinity immunoglobulin E receptor 1 (FcƐRI)) was performed (safety was reviewed by a Data Monitoring Committee - DMC). Independent sponsor members who were responsible for PK/ PD data analysis and Modeling \& Simulation were unblinded to the results of this interim analysis. The planned intent of this analysis was to confirm the dosing strategy for the youngest age group, 6-11 yrs and once the dose was to be confirmed, recruitment was supposed to be open for this age group. However, Novartis made a strategic decision to close recruitment in the study CQGE031G12301 and to terminate the study early, once all eligible participants in the study had completed week 12 assessments and the 16-week safety follow-up period. This decision was based on a blinded data review, which showed evidence of efficacy without the detection of any safety signal and that efficacy may be optimized with a different dosing regimen. Due to this decision, the final population size was 211, with only adolescent and adult participants (12 - 17yrs, and 18 - 55yrs) recruited.
