Effects of Traditional Chinese Medicine on Bronchiectasis Patients: A Multi-center, Randomized, Double-blind, Controlled Trial

The aim of this study is to evaluate the effectiveness of Traditional Chinese Medicine (TCM) on patients with clinically stable bronchiectasis by a multi-center, randomized, double-blind, controlled trial: one, TCM treatments based on syndrome differentiation; the other, a placebo of TCM treatment.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Bronchiectasis is a common and frequently occurring respiratory disease, with more hospitalization rate and mortality, poor quality of life and heavy financial burden. The main clinical manifestations are persistent or recurrent cough, expectoration, sometimes accompanied by hemoptysis, which can cause respiratory dysfunction and chronic pulmonary heart disease. There are some randomized controlled trials of TCM for bronchiectasis, and have the effect in the treatment of bronchiectasis, reducing the number of acute aggravation and alleviating dyspnea. However, some TCM interventions lack comprehensive syndrome differentiation and the placebo control.

This is a multi-center, randomized, double-blind, controlled trial to compare the efficacy to evaluate the effectiveness of TCM on patients with clinically stable bronchiectasis. 216 subjects will be randomly assigned to one therapies (TCM treatments based on syndrome differentiation) and the other therapy (placebo of TCM treatment) for 24 weeks. After the treatment period, the subjects will be followed up for 24 weeks. The primary outcomes include the frequency of bronchiectasis exacerbation, and the secondary outcomes include quality of life (SGRQ, LCQ, QOL-B), pulmonary function, safety observation index.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
The frequency of bronchiectasis exacerbation
Time Frame: Changes in the frequency of exacerbation at the week 12 and week 24 of the treatment phase, and at the week 24 of the follow-up phase compared with baseline.
The bronchiectasis exacerbations often result in reduced quality of life, increased rate of lung function decline, increased hospitalization. It is important to assess the changes of bronchiectasis exacerbations over time.
Changes in the frequency of exacerbation at the week 12 and week 24 of the treatment phase, and at the week 24 of the follow-up phase compared with baseline.

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
The time to the first bronchiectasis exacerbation
Time Frame: Week 24 of the treatment phase.
Week 24 of the treatment phase.
Changes in Forced expiratory volume in one second
Time Frame: Changes in FEV1 at the week 24 of the treatment phase and the week 24 of the follow-up phase compared with baseline.
Forced expiratory volume in one second (FEV1)is the amount of air that can be exhaled in one second. A positive change from baseline in FEV1 indicates improvement in lung function.
Changes in FEV1 at the week 24 of the treatment phase and the week 24 of the follow-up phase compared with baseline.

Other Outcome Measures

Other Outcome Measures

For clinical trials, a planned measurement described in the protocol that is used to determine the effect of an intervention/treatment on participants. For observational studies, a measurement or observation that is used to describe patterns of diseases or traits, or associations with exposures, risk factors, or treatment. Types of outcome measures include primary outcome measure and secondary outcome measure.
