About this study

Official title: A Randomised Controlled Trial of Mepolizumab Initiated Following Admission to Hospital for a Severe Exacerbation of Eosinophilic COPD

This is a single-centre, double-blinded, randomised, placebo controlled trial comparing mepolizumab 100mg versus placebo in patients with eosinophilic COPD, started following their index admission to hospital.

Read the detailed description

Patients admitted to hospital with an exacerbation of COPD are at high risk of readmission, of which a proportion are driven by eosinophilic inflammation. Whilst oral corticosteroids are beneficial in exacerbations, a considerable proportion of patients experience treatment failure, with 50% of patients readmitted within 3 months (www.RCPLondon.ac.uk).

Therapy, such as mepolizumab, reduces eosinophil count and has been shown to reduce exacerbation frequency when given in the stable state in both eosinophilic asthma (Papi et al. 2018) and COPD (Yousef, in press).

The investigators hypothesise that starting mepolizumab at the time of a hospitalisation for an exacerbation of COPD in patients with significant eosinophilia will result in a reduction in readmission to hospital in a high risk population.

Therefore, 238 participants will be recruited over an 18-month period and will be randomised into a 48-week treatment period in which they will receive monthly subcutaneous injections of either 100 mg mepolizumab or placebo. Secondary outcomes will be measured at baseline (week 0), 4 weeks, 8 weeks, 12 weeks, 24 weeks, 36 weeks and 48 weeks.

What is being measured

The primary outcome is the main question the study is designed to answer.

  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.

    Measured: 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)
  1. Total Number of Hospital Readmissions All Cause Over 48 Weeks

    The number of hospital readmissions (all cause) in total during the 48 (truncated follow-up minimum 24) weeks corresponding to each participant were calculated. Where no hospital admission have occurred a value of zero was derived.

    Measured: 0-48 weeks

  2. Total Number of Moderate Exacerbations Over 48 Weeks

    The severity of a COPD exacerbation was deemed as "Moderate" if the participant required treatment with steroids or antibiotics and was not hospitalised .

    The number of moderate exacerbations each participant had over the course of 48 (truncated follow-up minimum 24) weeks were calculated.

    Measured: 48 weeks

  3. Total Number of Severe Exacerbations Over 48 Weeks

    The severity of a COPD exacerbation was deemed as "Severe" if the participant required hospitalisation.

    The number of severe exacerbations each participant had over the course of 48 (truncated follow-up minimum 24) weeks were calculated.

    Measured: 48 weeks

  4. Total Number of Exacerbations Over 48 Weeks

    The number of exacerbations each participant had over the course of 48 (truncated follow-up minimum 24) weeks were calculated.

    Measured: 48 weeks

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

    The time from randomisation to next hospital readmission or death (due to a respiratory cause) is defined as a time to event outcome measured in days. The date of randomisation as well as the date of readmission or death due to respiratory causes (whichever occurs first) were used to calculate time to event. For participants not experiencing an event the time was calculated from randomisation until last known follow-up assessment event-free.

    Measured: 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).

  6. Time From Randomisation to Treatment Failure

    Treatment failure is defined as the composite of three endpoints: 1. treatment intensification with systemic corticosteroids and/or antibiotics for respiratory reasons; 2. step-up in hospital care for respiratory reasons including transfer to the intensive care unit or readmission; or 3. all-cause mortality)

    Measured: 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).

  7. Hospital Readmission (Respiratory Cause)

    Hospital readmission (respiratory cause). Number of individuals that readmitted during follow up is reported. Hospital readmission due to respiratory cause was analysed as a time to event outcome.

    Measured: Patients were followed up for up to 48 weeks (48 week visit had a window of +/- 1 week).

  8. Time From Randomisation to Next Hospital Readmission (All Cause)

    The time from randomisation to next hospital readmission (all cause) is defined as a time to event outcome measured in days. The date of randomisation and the date of next hospital readmission following randomisation was used to calculate time to event. Where hospital readmission doesn't occur during follow-up, time was measured until the participant's last known follow-up assessment.

    Measured: 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).

  9. Death (All Cause)

    All cause death. Number of individuals that died during follow up is reported. Death was analysed as a time to event outcome.

    Measured: Patients were followed up for up to 48 weeks (48 week visit had a window of +/- 1 week).

  10. Death (Respiratory Cause)

    Respiratory cause death. Number of individuals that died during follow up is reported. Death due to respiratory cause was analysed as a time to event outcome.

    Measured: Patients were followed up for up to 48 weeks (48 week visit had a window of +/- 1 week).

  11. Extended Medical Research Council Dyspnoea Score (eMRC)

    This scale measures perceived respiratory disability. Participants rate their grades of breathlessness on a scale of 1 (least) to 5 (worst). The extension divides the grade 5 rating into 'a' (independent) and 'b' (dependent) to establish dependence on others for washing and dressing.

    Measured: Weeks 0, 4, 8, 12, 24, 36, 48

  12. St George's Respiratory Questionnaire (SGRQ)

    This 50-item questionnaire measures health status (quality of life) in patients with diseases of airway obstruction. Scores are broken down into three components 'symptoms', 'activity', 'impacts', and the total score is calculated by summing the weights to all the positive responses in each component. For each subscale and the total score, values range from 0 (no impairment) to 100 (maximum impairment). Higher values represent a worse outcome.

    Measured: Weeks 0, 4, 8, 12, 24, 36, 48

  13. COPD Assessment Tool (CAT)

    The COPD Assessment Test (CAT) is a questionnaire for people with Chronic Obstructive Pulmonary Disease (COPD). It is designed to measure the impact of COPD on a person's life, and how this changes over time. Scores range from 0-40, with higher scores indicating greater impact of COPD on a patient's life.

    Measured: Weeks 0, 4, 8, 12, 24, 36, 48

  14. Warwick-Edinburgh Mental Wellbeing Scale (WEMWBS)

    This scale measures mental wellbeing using a 14-item scale. The scoring range for each item is from 1 - 5 and the total score is from 14-70, with higher scores indicating better mental wellbeing.

    Measured: Weeks 0, 4, 8, 12, 24, 36, 48

  15. London Chest Activities of Daily Living Questionnaire (LCADL)

    This 15-item questionnaire measures dyspnoea during routine daily activities in patients with COPD. It consists of four components: 'Self-care', 'household activities', 'Physical activity' and 'Leisure activities'. The questions in each of the four domains are scored as follows: 0 ("I wouldn't do it anyway"), 1 ("I do not get breathless"), 2 ("I get moderately breathless"), 3 ("I get very breathless"), 4 ("I have given this up") and 5 ("Someone else does this for me"). The LCADL total score sums all individual questions to give values in the range 0 to 75 (inclusive), with the highest score representing maximal disability.

    Measured: Weeks 0, 4, 8, 12, 24, 36, 48

  16. Short Physical Performance Battery (SPPB)

    SPPB ranges from 0 (worst performance) to 12 (best performance). This outcome measures lower extremity function using tasks that are similar to daily activities and it examines 3 areas: static balance, gait speed and getting in and out of a chair. The limitations based on the SPPB cut-off scores are defined as follows: "Severe limitations" if score is between 0-3, "Moderate limitations" if score is between 4-6, "Mild limitations" if score is between 7-9 and "Minimal limitations" if score is between 10-12. Lower scores indicate greater impairment.

    Measured: Weeks 0, 4, 8, 12, 24, 36, 48

  17. Handgrip Strength

    Handgrip strength is defined as a continuous outcome that measures the amount of static force that the hand can squeeze around a dynamometer. This outcome is measured in Kilograms.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this combined phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 24 Apr 2026). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Time From Randomisation to Next Hospital Readmission or Death (All Cause) (time frame: 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).). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT04075331, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?
