Outcome Measures

Primary Outcomes (1)

  • Time From Randomisation to Next Hospital Readmission or Death (All Cause)

    To evaluate the efficacy of mepolizumab initiated following hospitalisation on future hospital readmission or death (all cause) compared with placebo and standard medical therapy in severe exacerbations of eosinophilic COPD.

    Patients were followed up for up to 48 weeks (an absolute maximum of 49 weeks as the 48 week visit had a visit window of +- 1 week).

Secondary Outcomes (29)

  • Total Number of Hospital Readmissions All Cause Over 48 Weeks

    0-48 weeks

  • Total Number of Moderate Exacerbations Over 48 Weeks

    48 weeks

  • Total Number of Severe Exacerbations Over 48 Weeks

    48 weeks

  • Total Number of Exacerbations Over 48 Weeks

    48 weeks

  • Time From Randomisation to Next Hospital Readmission or Death Due to a Respiratory Cause

    Patients were followed up for up to 48 weeks (an absolute maximum of 49 weeks as the 48 week visit had a visit window of +- 1 week).

  • +24 more secondary outcomes

Eligibility Criteria

Age40 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Symptoms typical of COPD when stable (baseline eMRC dyspnoea grade 2 or more).
  • A clinician defined exacerbation of COPD requiring admission to hospital.
  • Serum eosinophil count of ≥ 300 cells/μL either at time of admission or at any one time in the preceding 12 months.
  • Smoking pack years ≥10 years.
  • Age ≥ 40 years.
  • Established on inhaled corticosteroids (ICS) prior to this admission.
  • Willing and able to consent to participate in trial.
  • Able to understand written and spoken English.

You may not qualify if:

  • COPD patients without eosinophilia (defined as persistently \< 300 cells/μL within the last 12 months).
  • Other conditions that may be the cause of eosinophilia (such as hypereosinophilic syndrome, eosinophilic granulomatosis, eosinophilic oesophagitis or parasitic infection).
  • Patients whose treatment is considered palliative (life expectancy \< 6 months).
  • Other respiratory conditions including active lung cancer, interstitial lung disease, primary pulmonary hypertension or any other conditions that in the view of the investigator will affect the trial.
  • Known history of anaphylaxis or hypersensitivity to mepolizumab or any of the excipients (sucrose, sodium phosphate dibasic heptahydrate, polysorbate 80).
  • Unstable or life-threatening cardiac disease including myocardial infarction or unstable angina in the last 6 months, unstable or life-threatening cardiac arrhythmia requiring intervention in the last 3 months and New York Heart Association (NYHA) Class IV heart failure.
  • Decompensated liver disease or cirrhosis.
  • Pregnant, breastfeeding, or lactating women. Women of child-bearing potential must agree to use appropriate methods of birth control and have a negative blood serum pregnancy test performed after randomisation but prior to first dosing with randomised treatment.\*
  • Participation in an interventional clinical trial within 3 months of visit 1 or receipt of any investigational medicinal product within 3 months or 5 half-lives.
  • Known blood born infection (e.g. HIV, hepatitis B or C).
  • Women of child bearing potential (WOCBP) - A woman is defined as being of childbearing potential (WOCBP), i.e. fertile, following menarche and until becoming post-menopausal, unless permanently sterile. Permanent sterilisation methods include hysterectomy, bilateral salpingectomy and bilateral oophorectomy. A postmenopausal state is defined as no menses for 12 months without an alternative medical cause.
