Depemokimab as an Extended treatmeNt Duration Biologic in Adults With Chronic Obstructive Pulmonary Disease (COPD) and Type 2 Inflammation (ENDURA-2)

Depemokimab is being developed as a treatment for individuals with moderate to severe COPD. The aim of this study is to assess the efficacy and safety of depemokimab compared as an add-on medicine in participants with uncontrolled moderate to severe COPD with type 2 inflammation.

Inclusion Criteria: * Participants must be greater than or equal to (\>=) 40 to less than or equal to (\<=) 80 years of age, at the time of signing the Informed consent * Elevated Blood Eosinophil Count (BEC) * Moderate to severe COPD with frequent exacerbations, defined as: * A clinically documented history of COPD as defined by the American Thoracic Society/European Respiratory Society for at least 1 year * A post-bronchodilator forced expiratory volume in one second (FEV1)/ forced vital capacity (FVC) ratio of \< 0.70 and a post-bronchodilator FEV1 \>30 percent (%) and \<= 80% predicted normal values * A well-documented history of at least 2 moderate or 1 severe exacerbation in the 12 months prior to screening * COPD assessment test (CAT) score \>=10 at Visit 1 * Smoking status: Current or former cigarette smokers with a history of cigarette smoking of \>=10 pack-years. * Participants should be on optimized inhaler therapy, defined as inhaled corticosteroid (ICS) plus Long-acting muscarinic receptor antagonist (LAMA) plus Long-acting beta2-adrenergic receptor agonist (LABA) either as multiple inhalers or a single combination inhaler for at least 6 months prior to Screening Visit 1 * Body mass index (BMI) \>=16 kilogram per square meter (kg/m\^2) * Male and eligible female participants Exclusion Criteria: The following subjects are excluded: * Participants with a current or prior physician diagnosis of asthma * Other clinically significant lung disease: The Investigator must judge that COPD is the primary diagnosis accounting for the clinical manifestations of the lung disease * Participants with pneumonia, COPD exacerbation, or lower respiratory tract infection within the 4 weeks prior to Screening Visit 1 * Lung resection: Participants with a history of or plan for lung volume reduction surgery / endobronchial valve procedure. * Pulmonary rehabilitation: Participants in the acute phase of a pulmonary rehabilitation program within 4 weeks prior to Screening Visit 1 * Continuous oxygen: Participants requiring oxygen supplementation for more than 12 hours per day * Cor pulmonale - resulting in right heart failure, severe pulmonary hypertension * Chronic hypercapnia requiring Non-invasive positive pressure ventilation (NIPPV) use (including Bi-Level Positive Airway Pressure \[BiPAP\] or Continuous Positive Airway Pressure \[CPAP\]) * Unstable cardiovascular disease or arrhythmia * Parasitic Infection: Participants with a known, pre-existing parasitic infection within 6 months of Screening (Visit 1)
