This research aims to assess the effectiveness and safety of lebrikizumab in adults diagnosed with perennial allergic rhinitis, a condition characterized by year-round nasal allergy symptoms. The study is a Phase 3 trial involving adult participants who have confirmed allergic reactions to indoor allergens. Researchers are investigating how lebrikizumab compares with placebo, alongside standard intranasal corticosteroid therapy, to better understand treatment options for this condition. Participants will receive either the investigational drug lebrikizumab (LY3650150) administered by subcutaneous injection, a placebo injection, or standard intranasal corticosteroid spray. The study is randomized, double-blind, and placebo-controlled, ensuring that neither participants nor researchers know who receives which treatment during the trial. Treatment and observation periods will span up to 29.5 months. During the study, participants will be monitored for changes in their nasal symptoms, specifically measuring the total nasal symptom score from the start of the study to week 16. Researchers will conduct various assessments including clinical evaluations and allergy testing to track symptom changes and treatment effects. Safety will be closely observed throughout the study duration, and participants may be followed for nearly two and a half years in total.
