Clinical Study on Guben Kechuan Granules Promoting Disease Recovery by Regulating Immune-Inflammatory Dysregulation in Patients With Acute Exacerbation of Chronic Obstructive Pulmonary Disease During the Peri-Discharge Period
Source: ClinicalTrials.gov · Last updated 6 Mar 2026
Brief summary (registry, in English)
Chronic Obstructive Pulmonary Disease (COPD) is one of the most common chronic airway diseases in China. Western medicine treatments have good clinical efficacy, but their effectiveness is limited in patients with Acute Exacerbation of COPD (AECOPD) during the peri-discharge period. Recurrent acute exacerbations remain an urgent clinical challenge to address. Traditional Chinese Medicine (TCM) has certain advantages in treating chronic airway diseases. Among them, Guben Kechuan Granules are widely used in respiratory diseases such as emphysema and COPD. However, high-level evidence for the use of Guben Kechuan Granules in patients with AECOPD during the peri-discharge period is currently lacking, and its mechanism of action has not been fully clarified.This study enrolled 126 patients with AECOPD during the peri-discharge period, who were randomly divided into the experimental group and the control group using a central randomization system. Both groups received treatment under the guidance of clinical guidelines, and the experimental group was additionally administered Guben Kechuan Granules. Follow-up assessments were conducted at 4 weeks, 8 weeks, and 12 weeks after treatment initiation, with efficacy indicators evaluated at 12 weeks. The primary efficacy endpoint was the improvement in Forced Expiratory Volume in 1 second (FEV1), while the secondary endpoints included the St. George's Respiratory Questionnaire (SGRQ), Modified Medical Research Council (mMRC) Dyspnea Scale, COPD Assessment Test (CAT), and 6-Minute Walk Test (6MWT). This study aims to scientifically evaluate the clinical efficacy of Guben Kechuan Granules in treating AECOPD during the peri-discharge period and generate high-quality clinical evidence.By detecting COPD-related inflammatory indicators, T-cell subsets, transcriptomics, serum metabolomics, and lipidomics, the mechanism of action of Guben Kechuan Granules in this patient population will be clarified. The study intends to elucidate its molecular mechanism of inhibiting inflammatory cascades through metabolic regulation, and screen metabolite marker clusters that can predict the response to integrated TCM and Western medicine treatment, thereby providing objective evidence for individualized precision intervention strategies.
