Stratified TreAtment to Reduce Risk in COPD
Stratified TreAtment to Reduce Risk in COPD
To evaluate the efficacy of blood-eosinophil directed corticosteroid therapy using
 near-patient testing, compared to current standard practice during an exacerbation of COPD in
 a multi-centre randomised placebo controlled trial.
Study design: Double-blind placebo controlled randomised clinical trial Study setting:
 Primary care GP practices Participants: Adults ≥40 years with COPD Sample size: 228 Study
 duration: 12 months data collection Primary objective: To evaluate the efficacy of
 blood-eosinophil directed corticosteroid therapy using near-patient testing, compared to
 current standard practice during an exacerbation of COPD.

 Secondary objective: To evaluate quality of life, symptoms, lung function and healthcare
 utilisation in a blood-eosinophil directed corticosteroid therapy arm.

 Exploratory objective: To evaluate stability of eosinophil counts and mediator levels

 Chronic obstructive pulmonary disease (COPD) affects adults and is largely caused by
 cigarette smoke in the developed world. It is predicted to be the 3rd leading cause of death
 by 2020 affecting over 250 million people worldwide. COPD is characterised by progressive
 airflow obstruction punctuated by frequent periods of worsening in respiratory symptoms and
 function associated with a significant impact on quality of life. These episodes are termed
 exacerbations and current treatment strategies rely on oral corticosteroids (prednisolone)
 and antibiotics but this is in a "one size fits all" approach. However there is little
 evidence supporting this strategy and both treatments can potentially cause harm. In addition
 to this, previous findings have shown that eosinophil counts within blood samples from COPD
 patients can be used as a biomarker to determine treatment with oral steroids.

 The use of near-patient testing in primary care will characterise patients with COPD and
 inform to guide effective and personalised treatment with reductions in treatment failure
 rates, improvements in health and reductions in adverse events associated with inappropriate
 and excessive corticosteroid and antibiotic therapy. Currently available systems include the
 HemoCue ® 5-point differential cell count system which accurately and rapidly (within 2
 minutes) determine the eosinophil count finger-prick sampling. This diagnostic is currently
 used in neonatology, Emergency Departments (ED) and at Mount Everest Base Camp 28-30. It is
 thus conceivable that this could be used in primary care to deliver a randomised control
 trial to demonstrate that stratified medicine approaches in the management of COPD
 exacerbations are superior to standard therapy.

 It is believed that personalising this treatment approach during an exacerbation of COPD, to
 direct whether corticosteroids is necessary for all patients, depending on the results of the
 eosinophil count from near-patient testing, is superior to current standard treatment
 strategies in the primary care setting.

 Recruitment target for STARR 2 is 228 participants with COPD from GP surgeries within the
 Thames Valley and South Midlands. A participant's involvement is 12 months and involves up to
 5 visits. These visits consist of CRF completion, questionnaires, breathing tests, urine
 testing, blood samples and spirometry. The trial drugs are only taken for 14 days during an
 exacerbation but participants can be re-randomised for up to 4 times in the study when they
 exacerbate.

 Intervention: At exacerbation randomised to 'standard therapy' or 'blood eosinophil directed
 therapy'. Standard therapy will be prednisolone and antibiotic therapy. Blood eosinophil
 directed therapy will be prednisolone and/or antibiotic therapy.

 Investigational medicinal product: Prednisolone or placebo equivalent. The IMP is part of
 current clinical practice. Prednisolone is an anti-inflammatory and given in short durations
 (≤2 weeks duration) orally for its systemic action at the onset of an exacerbation in COPD.

 Participation duration: Study entry at stable state or during an exacerbation. Randomisation
 at exacerbation. IMP treatment period 14 days. Post treatment follow-up visits at days 14, 30
 and 90. Stable state and randomisation visit duration maximum 60 minutes. Follow-up visits at
 days 14, 30, and 90 maximum duration 30 minutes. Participants may be re-randomised and
 followed up if they have further exacerbations after the 30 day visit.

 Data collection: Demographic and exacerbation clinical data including duration of symptoms,
 past medical history, medication history and exacerbation history is collected. Blood
 eosinophil tests is collected by pin-prick testing using the HemoCue ®; lung function using
 spirometry and FeNO; and symptoms and quality of life using questionnaires. Serum is
 collected at visits.

 Study schedule:

 Study assessments will be performed within primary care by the research study team. The
 following assessments may occur at the study visits:

 Eligibility check: Inclusion and exclusion criteria will be checked against the participant's
 medical notes and with the participant during the visit. This responsibility will be
 delegated by the PI to a member of the research team.

 Demographic history: Participant demographics including age, smoking history and past COPD
 medical history will be collected.

 Medication history: Full medication history will be collected, including the use of as
 required and over the counter medication. Any drug allergy will be documented and dates of
 flu vaccination, S. pneumoniae and H. influenzae B vaccinations will be recorded from medical
 records.

 Past medical history: Full medical history will be collected from the participant and from
 the medical notes. COPD diagnosis history: The age of onset and age of diagnosis of COPD
 symptoms will be recorded from the participant and from the medical records.

 Past exacerbation history: The frequency of exacerbations, including those requiring
 hospitalisation in the previous 12 months will be captured from participant recollection and
 from the medical records. Medication prescribed at each exacerbation event (if available)
 from medical records will be captured.

 Exacerbation history: The current history of the exacerbation, including duration of symptoms
 and treatment history will collected by questioning. The severity of the exacerbation will be
 recorded according to Anthonisen criteria14 with increased symptoms of breathlessness, sputum
 production and sputum purulence will be used as per GOLD31 definition. The Anthonisen
 criteria for exacerbation as follows: Type 1 - Three major symptoms; Type 2 - two major
 symptoms; Type 3 - One major and one minor symptom. The major symptoms are i) Increased
 breathlessness; ii) increased sputum production; or iii) increased sputum purulence. The
 minor symptoms are iv) Upper respiratory tract infection in the previous 5 days; v) fever
 without apparent cause; vi) increased wheeze; vii) increased cough; viii) increase in
 respiratory or heart rate 20% above baseline. Questionnaires: Patient reported outcome
 measures (PRO's) will be sought to specifically test symptoms, health status, quality of life
 and any associated depression and anxiety. This will include the Medical Research Council
 dyspnoea scale (MRC); Visual analogue score (VAS) 32; COPD Assessment Tool (CAT) 33; the
 Hospital Anxiety and Depression Scale (HADS)34 and the EuroQol 5D35. Participants will be
 asked to complete a daily diary (using the VAS tool, for the duration of 30 days) for
 assessment of symptoms and recovery following treatment. Instructions to use these
 questionnaires will be given to all participants. Each of these questionnaires are validated
 to be self-completed for ease of use. All research staff undertaking any assessments and
 procedures will be trained to use the equipment and perform the questionnaires to determine
 patient reported outcomes. Near-patient point of care testing procedures:

 Approximately 5 drops of blood (up to a maximum of 10 drops) will be taken for measurement of
 peripheral blood eosinophil counts, glucose and CRP levels.

 A urine sample for testing of glycosuria will be performed immediately. All samples will be
 discarded.

 Lung Function: Spirometry will be performed to determine the forced expiratory volume in 1
 second (FEV1) and the forced vital capacity (FVC) according to standard ATS/ERS criteria36.

 Venous blood sampling: Using a fully sterile technique, a blood test will be performed to
 measure inflammation. All participants consenting to trial sample collection will have a
 maximum of 20mLs of blood taken at each visit. Collected blood will be centrifuged
 immediately and serum/plasma will be aliquoted into fully anonymised barcoded tubes.
 Anonymised samples will be then be securely transported to the John Radcliffe Hospital and
 stored at the Respiratory Medicine Laboratory (John Radcliffe Hospital), under the HTA
 licence, at -80˚c for exploratory outcome analysis and for future use subject to ethical
 approval. There will be separate instructions detailing the sample handling process for this
 study.
