Plain English Summary
Background and study aims
Chronic obstructive pulmonary disease (COPD) is a chronic inflammatory disease and currently a leading cause of chronic morbidity (long-term illness) and mortality (death). Inhaled corticosteroids (ICS) belong to the first line treatment for COPD patients; however, there are patients who do not get a significant clinical benefit from ICS. Additionally, ICS overuse results in considerable side effects and economic burden. The aim of this study is to investigate parameters that may help to identify COPD patients that respond better from patients that respond worse to treatment with ICS.
Who can participate?
COPD patients aged 40 and over
What does the study involve?
Participants undergo bronchoscopy, where an instrument called a bronchoscope is threaded through the nose and down the throat to examine the airways and take biopsies (tissue samples). Participants are then divided into two groups based on the area of airway smooth muscle cells (ASMCs). Group A includes patients with ASMC area over 20% and group B includes patients with ASMC area of 20% and lower. All patients are treated for 6 weeks with all three drugs: LAMA (aclidinium), LABA (formoterol) and ICS (budesonide). Patients from each group are then randomly allocated to receive either treatment with LAMA, LABA and ICS (groups A1 and B1) or treatment with LAMA, LABA and placebo (dummy drug) (groups A2 and B2) for 12 months. Participants are followed up at 3, 6, 9 and 12 months, undergo lung function and walking distance tests, and give blood samples and oropharyngeal (throat) swabs.
What are the possible benefits and risks of participating?
Participants receive all tests and treatments for free for the duration of the study (12 months). The risks of the study procedures are considered to be mild. The medication is licensed for use in COPD. Bronchoscopy is a routine test in patients with COPD and the risks of the procedure are minimal. Additional blood samples are taken at the start of the study, scheduled visits and COPD episodes. Oropharyngeal swabs are an established method to take samples and can cause mild discomfort. All other procedures, including lung function and walking distance tests, are standard tests in COPD treatment. The side effects of inhaled steroids are usually mild, such as oral candidiasis (fungal infection in the mouth) and hoarseness. Patients are instructed at each visit how to avoid side effects (e.g. washing the mouth). The study team examine patients for any side effects.

Scientific title
Histological, cellular and molecular investigation of steroid responsiveness in chronic obstructive pulmonary disease - the HISTORIC study
Acronym
HISTORIC
Study hypothesis
Chronic obstructive pulmonary disease (COPD) patients with increased airway smooth muscle cell (ASMC) area respond better to inhaled corticosteroids (ICS) and this type of histological analysis can predict steroid responsiveness in COPD patients.

Intervention
188 patients with COPD, GOLD groups B-D, are recruited within 18 months. Based on the histological analysis of endobronchial biopsies taken by flexible bronchoscopy, patients are divided into two groups. Group A includes patients with ASMC area >20% and group B includes patients with ASMC area ≤20%. All patients follow a run-in period of 6 weeks on open-label triple therapy with LAMA (aclidinium 400 mcg, bid), LABA (formoterol 12 mcg, bid) and ICS (budesonide 400 mcg, bid). Subsequently, patients from each group are randomized (1:1) to receive either:
1. Triple treatment with LAMA, LABA and ICS (groups A1 and B1) or
2. Combined bronchodilator therapy with LAMA and LABA and placebo for ICS (groups A2 and B2)
Randomization will be stratified by group (A vs B), follow a block size of 4. The duration of treatment will be 12 months, with follow-up at 3, 6, 9 and 12 months after randomization.

Primary outcome measures
To compare the differences in the mean decrease of post-bronchodilator FEV1 in milliliters measured using a spirometer at 12 months, between patients with low (≤20%) and high (>20%) ASMC area and according to whether they received ICS or not
Secondary outcome measures
Immediately after the run-in phase, at 3, 6, 9 and 12 months after randomization to compare changes in:
1. Modified Medical Research Council (MMRC) dyspnea scale
2. COPD assessment test (CAT)
3. Health-related quality of life, measured using SF-36, SGRQ
4. Pre and post bronchodilator body plethysmography/DLCO
5. Expiratory FeNO
6. Single and multiple-breath N2 wash-out
7. Forced impulse oscillometry
8. 6-minute walking distance (6MWD)
9. Movement patterns, measured using accelerometry
10. Therapy-related side effects (oral candidiasis, tachycardia, tremor, hoarseness, pneumonia)
11. Exacerbations rate
12. Serum biomarkers
between patients with low (≤20%) and high (>20%) ASMC area and according to whether they received ICS or not
