Phase IIb Study of AZD0292 IV to Prevent Exacerbations in Patients 12 Years and Older with Bronchiectasis and Chronic Pseudomonas Aeruginosa Infection

What this Trial Is About

Researchers are evaluating AZD0292, a bispecific IgG1k monoclonal antibody, for preventing exacerbations in bronchiectasis patients who are chronically colonized with Pseudomonas aeruginosa PsA. This Phase IIb study compares two dosage regimens of AZD0292 administered intravenously with placebo in participants aged 12 years and older. The study mainly focuses on non-cystic fibrosis bronchiectasis patients with frequent pulmonary exacerbations due to chronic PsA colonization, which negatively affects lung function, quality of life, and survival. Additionally, patients with cystic fibrosis bronchiectasis colonized with PsA are included as an exploratory group. Participants will receive either high-dose or low-dose AZD0292 starting on Day 1 via IV infusion, or placebo administered similarly. Subsequent doses will follow a schedule of assessments. This randomized, double-blind, placebo-controlled, parallel study aims to assess the efficacy, safety, and pharmacokinetics of AZD0292 over a variable follow-up period ranging from a minimum of 28 weeks up to 52 weeks. The trial also includes monitoring for adverse events and immune responses to the treatment. During the study, participants will undergo evaluations including lung function tests, quality of life questionnaires, and monitoring of exacerbation rates. Blood samples will be collected to measure drug concentration and antibody development. Safety assessments will continue through the treatment period and for up to 24 weeks after the last dose. The primary outcome is the annualized rate of exacerbations over the follow-up time, and secondary measures include severe exacerbation rates, time to first exacerbation, and changes in quality of life scores. Total participation spans from screening through the treatment and follow-up phases.
