AI summary

From the trial's eligibility criteria. Machine-read from the registry text on this page, so it can be wrong. The registry text below and the trial team decide who can take part.

The trial is looking for adults aged 40 to 80 with moderate to severe COPD and frequent flare-ups, who have a raised blood eosinophil count and are already on regular inhaler treatment.

Age
40 to 80 years
Sex
Men and women can join.
Disease stage
Moderate to severe COPD, diagnosed for at least 1 year, with at least 2 moderate or 1 severe flare-up in the 12 months before screening. FEV1/FVC ratio below 0.70 and FEV1 above 30% and up to 80% of predicted. CAT score of 10 or more.
Earlier treatment
Must have been on inhaled corticosteroid plus LAMA plus LABA (in multiple inhalers or one combination inhaler) for at least 6 months before screening.
Biomarker or test result
Elevated blood eosinophil count (BEC).

Main reasons for not taking part

  • Current or past doctor diagnosis of asthma
  • Other significant lung disease, where COPD is not the main diagnosis
  • Pneumonia, COPD flare-up or lower respiratory tract infection in the 4 weeks before screening
  • Needing oxygen for more than 16 hours a day
  • Unstable heart disease or irregular heart rhythm

  • Unstable cardiovascular disease or arrhythmia
  • Parasitic Infection: Participants with a known, pre-existing parasitic infection within 6 months of Screening (Visit 1)
  • The following subjects are excluded:
  • Continuous oxygen: Participants requiring oxygen supplementation for more than 16 hours per day to maintain resting oxygen saturation greater than 88%
  • Chronic hypercapnia requiring Non-invasive positive pressure ventilation (NIPPV) use (including Bi-Level Positive Airway Pressure [BiPAP] or Continuous Positive Airway Pressure [CPAP])

About the trial

What the trial wants to find out

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.

The 2 groups in the trial

  • DepemokimabTreatment being tested

    Participants will be administered subcutaneous (SC) injection of Depemokimab along with standard of care (SoC).

  • PlaceboPlacebo, for comparison

    Participants will be administered placebo along with SoC.
