Efficacy and safety of Jia Wei Bushen Yiqi formulas as an adjunct therapy to systemic glucocorticoids on acute exacerbation of COPD: study protocol for a randomized, double-blinded, multi-center, placebo-controlled clinical trial.


ABSTRACT:

Background

Systemic glucocorticoids are effective for the management of chronic obstructive pulmonary disease (COPD) exacerbation but have serious adverse effects. Traditional Chinese medicine (TCM) can bring additional benefits to these patients but has few adverse effects. The present study aims to evaluate the efficacy and safety of Jia Wei Bushen Yiqi (JWBY) formulas in patients who suffer from COPD exacerbations and to investigate whether the short-term (5-days) systemic glucocorticoid therapy is non-inferior to the long-term (9-day) regime.

Methods

In this multi-center, randomized, double-blinded trial, eligible inpatients with COPD exacerbation are randomly assigned to four groups (A, B, C, and D). Group A will receive placebo plus 5-day prednisone, group B will receive placebo plus 9-day prednisone, group C will receive JWBY formulas plus 5-day prednisone, and group D will receive JWBY formulas plus 9-day prednisone. The primary outcomes are the time interval to the patient's next exacerbation during a 180-day following up and the COPD assessment test (CAT) during treatment. Secondary outcomes include lung function, TCM syndrome assessment, laboratory tests, and safety. The changes of the hypothalamic pituitary adrenaline axis (HPA axis) and inflammatory cytokine will be measured as well.

Discussion

By demonstrating the advantages of utilizing TCM and an appropriate duration of systemic glucocorticoids, this effectiveness comparison trial will provide new references to physicians on how to improve the management of COPD exacerbation. The results of HPA axis and inflammation cytokine measurements will shed light on the molecular mechanisms and entail further mechanism studies.
