What this study is about
Depemokimab is being developed as a treatment for individuals with moderate to severe Chronic Obstructive Pulmonary Disorder (COPD). The aim of this study is to assess the effectiveness and safety of early initiation of depemokimab as an add-on medicine in participants with moderate to severe COPD with type 2 inflammation.

Depemokimab is being developed as a treatment for individuals with moderate to severe Chronic Obstructive Pulmonary Disorder (COPD). The aim of this study is to assess the efficacy and safety of early initiation of depemokimab as an add-on medicine in participants with moderate to severe COPD with type 2 inflammation.
Interventions
DRUG
Depemokimab
Depemokimab will be administered.
DRUG
Placebo
Matching placebo will be administered.
Primary outcome measures
Annualized Rate of Moderate/Severe Exacerbations
Time frame: From Baseline Up to Week 156
Moderate exacerbations are defined as clinically significant exacerbations that require treatment with oral/systemic corticosteroids and/or antibiotics. Severe exacerbations are defined as clinically significant exacerbations that require in-patient hospitalization (that is greater than or equal to \[\>=\] 24 hours) or result in death. The frequency of moderate/ severe exacerbations expressed as an annualized rate of moderate or severe exacerbations will be reported.
Who can participate
This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.
Inclusion criteria
- Male or eligible female participants
- Eosinophilic phenotype measured using Blood Eosinophil Count (BEC)
- Moderate to severe COPD, defined as
- A clinically documented history of COPD for at least 1 year
- A post-salbutamol Forced expiratory volume in one second (FEV1)/Forced vital capacity (FVC) ratio of less than (\<)0.70 and a post-salbutamol FEV1 greater than (\>)30 percent (%) and \<80% predicted normal values
- Elevated risk for exacerbations, defined as
- A well-documented history of only 1 moderate COPD exacerbation in the prior 12 months and
- The presence of risk factors for future exacerbations/deterioration such as:
- Modified Medical Research Council (mMRC) dyspnea score \>= 2
- COPD Assessment Test (CAT) \>= 15
- Post-bronchodilator FEV1 \< 50% predicted
- Chronic bronchitis
- Smoking status: Current or former cigarette smokers with a history of cigarette smoking of \>=10 pack-years at Screening.
- Dual (Inhaled corticosteroid (ICS)+ Long-acting beta2-adrenergic receptor agonist \[LABA\] or LABA+ Long-acting muscarinic receptor antagonist \[LAMA\]) or triple (ICS+LABA+LAMA) inhaler therapy as assessed by the investigator for at least 3 months
- Body mass index (BMI) \>=16 kilograms per square meter (kg/m\^2)
Exclusion criteria
- The Investigator must judge that COPD is the primary diagnosis accounting for the clinical manifestations of lung disease, and clinical manifestations of lung disease where primary diagnosis is not COPD are excluded
- Participants with a current or prior physician diagnosis of asthma
- Participants with childhood asthma are permitted, provided that childhood asthma has resolved before 18 years of age and has not recurred
- Other clinically significant lung disease: The Investigator must judge that COPD is the primary diagnosis accounting for the clinical manifestations of the lung disease.
- COPD severity: Participants with more than one moderate exacerbation or severe exacerbation in the past 12 months prior to Visit 1
- COPD stability: Participants with pneumonia, COPD exacerbation, or lower respiratory tract infection within the 4 weeks prior to 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 Visit 1
- Chronic hypercapnia requiring non-invasive positive pressure ventilation (NIPPV) use including Bi-Level Positive Airway Pressure (BiPAP) or Continuous Positive Airway Pressure (CPAP) are excluded
- Continuous oxygen: Participants requiring oxygen supplementation for COPD

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
