Depemokimab as an Extended treatmeNt Duration Biologic in Adults With Chronic Obstructive Pulmonary Disease (COPD) and Type 2 Inflammation (ENDURA -1)

A Randomized, Double-Blind, Placebo- Controlled, Parallel-Group, Multicenter Study of the Efficacy and Safety of Depemokimab In Adult Participants With COPD With Type 2 Inflammation


Sponsor

GlaxoSmithKline

Enrollment

981 participants

Start Date

Jun 20, 2025

Study Type

INTERVENTIONAL

Conditions

Summary

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 as an add-on medicine in participants with uncontrolled moderate to severe COPD with type 2 inflammation.


Eligibility

Min Age: 40 YearsMax Age: 80 Years

Inclusion Criteria11

  • 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.

  • 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 less than (\<) 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 or eligible female participants.

Exclusion Criteria11

  • 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).
