Detailed Description
Patients with severe or very severe COPD are more likely to suffer repeated exacerbations and more rapidly declining lung function generating increased risk of death and time to a COPD related hospitalization. Although many therapies exist and are being developed to relieve symptoms and reduce mortality in COPD, most have only been studied in moderate to very severe COPD. There are few clinical trials to compare therapeutic alternatives in severe and very sever COPD. Furthermore, some randomized controlled trials on comprehensive Traditional Chinese medicine (TCM) interventions, especially based on the TCM patterns, have been the certain evidence for showing definite effect for COPD patients. In addition, a study about the effect of TCM on outcomes in mild and moderate COPD patients has been in progress and will be carried out in December 2014 (NCT01486186). Hence, corresponding to the mild to moderate COPD patients, The this study aims to evaluate the effectiveness of TCM on severe / very severe COPD patients.
This is a multi-center, randomized, double-blind, controlled study to evaluate the effectiveness of TCM on severe / very Severe COPD patients. Following a 14 day run-in period, approximately 564 subjects will be randomly assigned to conventional medicine treatment group, TCM and conventional medicine treatment group for 52 weeks. After the 52 weeks treatment period, subjects in two treatments arms will follow-up 52 weeks. The primary outcome measure is the frequency of exacerbations. The secondary efficacy measures include all-cause mortality, FEV1, dyspnea (MMRC), exercise capacity( 6MWD), quality of life ( CAT, SF-36 and COPD-PRO), and effectiveness satisfaction with treatment(ESQ-COPD) . Safety will be assessed through the collection of adverse events. There will be a total of 9 study visits (baseline, the 13, 26, 39 and 52 weeks of the treatment, the 13, 26, 39 and 52 weeks of follow-up).

Intervention / Treatment |
---|---|
Experimental: Conventional medicine+ placebo TCM
Patients in this group will be given conventional medicine, Salmeterol / fluticasone based on the classes of medications recommended by 2011 GOLD and Chinese Treatment Guidelines for COPD, and three placebo TCM treatment, which are which are placebo Bufeijianpi granule, placebo Bufeiyishen granule and placebo Yiqizishen granule corresponding to the three traditional Chinese syndromes in sequence, which are syndrome of deficiency of pulmono-splenic qi, syndrome of insufficiency of qi of the lung and kidney, syndrome of insufficiency of qi and yin of the lung and kidney.
|
According to the revised 2013 GOLD, Salmeterol / fluticasone was used to severe and very severe COPD patients for 52weeks: Salmeterol / fluticasone (Seretide®, GlaxoSmithKline), 50/500 μg / dose, 60 inhalations.
50/500 μg each time, twice daily.
According to traditional Chinese syndrome differentiation and treatment, patients with syndrome of deficiency of pulmono-splenic qi will be given placebo Bufeijianpi granule, twice daily for 52 weeks for lower dosage.
According to traditional Chinese syndrome differentiation and treatment, patients with syndrome of insufficiency of qi of the lung and kidney will be given placebo Bufeiyishen granule, twice daily for 52 weeks for lower dosage.
According to traditional Chinese syndrome differentiation and treatment, patients with syndrome of insufficiency of qi and yin of the lung and kidney will be given placebo Yiqizishen granule granule, twice daily for 52 weeks for lower dosage.

Experimental: conventional medicine+ TCM
Patients in this group will receive Salmeterol / fluticasone based on the classes of medications recommended by 2011 GOLD and Chinese Treatment Guidelines for COPD, and three types of TCM treatment, which are Bufeijianpi granule, Bufeiyishen granule and Yiqizishen granule.
A herbal extract twice daily for 52 weeks for lower dosage.
The three granules are corresponding to the three traditional Chinese syndromes in sequence, which are syndrome of deficiency of pulmono-splenic qi, syndrome of insufficiency of qi of the lung and kidney, syndrome of insufficiency of qi and yin of the lung and kidney.
