Background and study aims
Chronic obstructive pulmonary disease (COPD) is the name for a group of lung conditions that cause breathing difficulties.
Patients with COPD commonly experience flare-ups (“acute exacerbations”) and antibiotics are often prescribed. However, only one in three flare-ups are caused by bacterial infections and are helped by antibiotics. The remaining two out of three flare-ups are caused by viruses or environmental factors and in these cases, antibiotics will not help. If you take antibiotics, you are more likely to suffer from an infection from drug-resistant bacteria in the future, so it is important to find a safe and effective way to control the symptoms of COPD flare-ups without using antibiotics. There is evidence, based on studies conducted in China, that a herbal combination treatment called Shufeng Jiedu could help control symptoms of COPD flare-ups.
We would like to know whether the herbal combination, Shufeng Jiedu, could be an alternative to antibiotics. As this study is a feasibility study, it will not answer this question but this will help us to plan a large, full-scale trial.

Who can participate?
COPD patients aged 40 years or older who present at their GP Practice with an acute exacerbation of COPD will be invited to take part in the EXCALIBUR trial.

What does the study involve?
Eligible patients (participants) will be randomly allocated to Shufeng Jiedu (SFJD) capsules or matched placebo (dummy capsule), and will take 4 capsules, 3 times a day for 14 days. Participants will be asked to complete a participant diary for 28 days, recording their COPD flare-up symptoms in a symptom questionnaire and any medication they have taken for their flare-up (including the trial treatment). The participants will receive a final questionnaire mailed to them at 12 weeks post-randomisation. Research sites will perform a review of the participant's notes 12 weeks post-randomisation to record any further GP visits or hospital admissions. Participants will also be interviewed at 4 weeks to give their views on the trial documents, design, and herbal treatment.

What are the possible benefits and risks of participating?
It is not known whether you will have any additional benefit from taking part in this trial. However, your participation will give important information about how best to treat people with flare-ups of their COPD.
You may experience mild side effects from taking the trial medication.

Scientific titleTreating Acute EXacerbation of COPD with Chinese HerbAL MedIcine to aid AntiBiotic Use Reduction (EXCALIBUR) - Study of Shufeng Jiedu® (SFJD) capsules to aid antibiotic use reduction in acute exacerbations of chronic obstructive pulmonary disease: a mixed-methods, double blind, randomised placebo-controlled feasibility trial
Study acronymEXCALIBUR
Study objectivesWe hypothesise that SFJD will improve symptoms in people with AECOPD, and will therefore reduce the necessity for antibiotics, the risk and duration of admission to hospital, and the risk of relapse. This trial will be a feasibility study in patients treated for AECOPD in primary care in the UK, in preparation for a full trial to assess whether adding SFJD to standard treatment will enable patients to improve faster, thus reducing the necessity for antibiotics and reducing their risk of admission to hospital. If successful, this would pave the way for a full-scale clinical trial in the UK. The addition of SFJD to antibiotics has the potential to significantly reduce healthcare costs associated with COPD and to reduce the risk of development of antimicrobial resistance, by reducing the number of antibiotic prescriptions and reducing the risk and duration of hospital admission.

InterventionOVERVIEW
This is a multicentre, double blind placebo-controlled feasibility trial of Shufeng Jiedu® in treating symptoms of acute exacerbations of COPD (AECOPD). This trial will also contain nested qualitative interviews of patients who choose to take part and those who don't, in order to help aid the design of the large, full-scale trial.

POPULATION
We aim to recruit 80 adults, 40 years and over, presenting to their GP with an acute exacerbation of their COPD and with at least one of the Anthonisen criteria (increased pus in sputum; increased sputum volume; increased breathlessness), and the GP is considering use of antibiotics.

IDENTIFICATION
Potential participants will be made aware of the EXCALIBUR trial via mail-out from the 8 recruiting GP sites. The criteria for receiving a mail-out pack will be for patients to have experienced an acute exacerbation (flare-up) of their COPD (AECOPD) in the last two years. This mail out pack will inform the patient about the trial and to contact their GP next time they suffer an AECOPD, before taking any AECOPD treatment.

ELIGIBILITY
On presentation at a GP Practice with an AECOPD, the patient will be assessed for eligibility from the patient notes and by clinical assessment of their symptoms.

TREATMENT
Eligible participants will be randomised to active or placebo IMP in a 1:1 allocation, on top of usual care for AECOPD (such as antibiotics and oral corticosteroids). Participants will be asked to take the trial medication of 4 capsules, 3 times a day, preferably after meals, for 14 days. GPs will be given the option to prescribe immediate; delayed; or no antibiotics on the trial based on the clinical assessment of the patient and their symptoms.

PARTICIPANT DIARY
Participants will be asked to complete daily diary data for up to 28 days after presentation at their GP practice. This diary collects information on the patients' symptoms as well as any treatment taken for the AECOPD. The diary may be completed early if the participant's exacerbation has ended for 7 days and the diary has been completed for at least 14 days.
Patients will receive follow up phone calls or text messages from the research team at the Southampton Clinical Trials Unit (SCTU) at 2-3; 14; and 28 days following randomisation to prompt diary completion and return.
A final COPD Assessment Test (CAT) questionnaire will be mailed to the participant at 12 weeks post-randomisation, after which their involvement in the trial will be complete.

NOTES REVIEW
A notes review will be undertaken 12 weeks after randomisation to document return visits to the GP for repeat COPD consultations, antibiotic prescriptions, other medications prescribed for treatment of AECOPD and hospital attendances (both inpatient and outpatient).

NESTED QUALITATIVE SUBSTUDY
As part of the EXCALIBUR trial, we would like to talk to both people who entered the trial and those who chose not to enter. We will ask patients about their views on herbal medicine and delayed prescriptions of antibiotics in the treatment of flare-ups of COPD. Additionally, we wish to learn about their experience of taking part in the EXCALIBUR trial or their reasons for not doing so.
These interviews will range from 15-60 minutes long and be conducted over the telephone.
