Brief summary
This study aims to establish the treatment scheme of Yiqi Huoxue Huatan granule for chronic obstructive pulmonary disease (COPD) with chronic respiratory failure (CRF), reducing mortality, improving quality of life and forming high quality evidence.
Detailed description
COPD is a highly prevalent disease, with a prevalence among people 40 years of age or older of 10.1% worldwide and 13.7% in China. COPD has become the third leading cause of death worldwide. COPD complicated by CRF is serious and has a high mortality rate. At present, ideal and effective treatment is inadequate. Traditional Chinese medicine (TCM) has some potential in improving outcomes in COPD with CRF. This is a multicenter, randomized, double-blind, placebo controlled trial to evaluate the effect of Yiqi Huoxue Huatan granule on reducing mortality and improving quality of life in COPD with CRF. After a 14-day run-in period, 372 subjects will be randomly assigned to treatment group or control group for 52-week treatment, followed by 52-week follow-up. The primary outcomes are all-cause mortality and frequency of acute exacerbation of COPD. The secondary outcomes include clinical symptoms, COPD assessment test (CAT), arterial blood gas analysis, pulmonary function and duration of mechanical ventilation. Safety will also be assessed.
Interventions
Yiqi Huoxue Huatan granule will be administered twice daily for five days a week for 52 weeks,Tiotropium Bromide Powder for Inhalation will be used once daily (18 μg each time) for 52 weeks, Salmeterol / Fluticasone Powder for Inhalation will be used twice daily (50ug/250ug each time) for 52 weeks, Budesonide / Formoterol Powder for Inhalation will be used twice daily (320ug/4.5ug each time) for 52 weeks.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| All-cause mortality | Up to week 52 of the follow-up phase. | All-cause mortality will be calculated in this study. |
| Frequency of acute exacerbation of COPD | Up to week 52 of the follow-up phase. | Frequency of acute exacerbation of COPD will be recorded. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Arterial partial pressure of oxygen (PaO2) | Change from baseline PaO2 at week 13, 26, 39 and 52 of the treatment phase, and week 13, 26, 39 and 52 of the follow-up phase. | PaO2 will be evaluated by arterial blood gas analysis. |
| Arterial partial pressure of carbon dioxide (PaCO2) | Change from baseline PaCO2 at week 13, 26, 39 and 52 of the treatment phase, and week 13, 26, 39 and 52 of the follow-up phase. | PaCO2 will be evaluated by arterial blood gas analysis. |
| Clinical symptom assessment questionnaire | Change from baseline clinical symptom assessment questionnaire scores at week 13, 26, 39 and 52 of the treatment phase, and week 13, 26, 39 and 52 of the follow-up phase. | Clinical symptom assessment questionnaire of COPD will be used to assess symptoms. |
| Duration of mechanical ventilation | Change from baseline duration of mechanical ventilation at week 13, 26, 39 and 52 of the treatment phase, and week 13, 26, 39 and 52 of the follow-up phase. | The duration of mechanical ventilation will be recorded. |
| Health economics | Up to week 52 of the follow-up phase. | Cost of the treatment phase and follow-up phase will be recorded |
| FEV1 | Change from baseline FEV1 at week 52 of the treatment phase, and week 52 of the follow-up phase. | Forced expiratory volume in one second ( FEV1) will be used to assess pulmonary function. |
| CAT | Change from baseline CAT scores at week 13, 26, 39 and 52 of the treatment phase, and week 13, 26, 39 and 52 of the follow-up phase. | COPD assessment test (CAT) will be used to assess quality of life. |
