Group Intervention Description Rademikibart Rademikibart in prefilled syringe - Placebo Matching placebo in prefilled syringe -
- Primary Outcome Measures
Name Time Method Treatment failure rate 28 days Treatment failure is defined as death due to any cause, (re)admission to a hospital for COPD, ED (re)visit or unscheduled medical visit for worsening of COPD symptoms, or the necessity to intensify pharmacologic treatment (including second course of systemic steroids for COPD exacerbation) within 28 days after randomization.
- Secondary Outcome Measures
Name Time Method Absolute CFB in post-BD FEV1 at Day 3, Week 1, and Week 4 Day 3, Week 1, and Week 4 Absolute change from baseline in post-bronchodilator forced expiratory volume (FEV1) at Day 3, Week 1, and Week 4
Incidence of adverse events (AEs), including serious adverse events (SAEs), adverse event of special interest (AESIs), and drug-induced liver injury (DILI) reported 56 days Incidence of unanticipated adverse device effects (UADEs) 56 days Incidence of injection site reactions 56 days Rate of new moderate and severe COPD exacerbations over the 28 days after randomization 28 days Time to the first new moderate or severe COPD exacerbation in the 28 days after randomization 28 days Mean change from baseline (CFB) in EXACT-PRO score Week 1, Week 2, and Week 4 Mean CFB in clinical respiratory symptoms of COPD using the E-RS: COPD (Evaluating Respiratory Symptoms in COPD) comprised in the EXACT-PRO through Week 1, Week 2, and Week 4. The Exacerbations of Chronic Pulmonary Disease Tool - Patient-Reported Outcome (EXACT-PRO) is a PRO instrument designed to capture information on the occurrence, frequency, severity, and duration of exacerbations of disease in patients with COPD.
