NCT03310385

Brief Summary

This study is a phase 2, multicentre, dose-finding, double-blind, randomized placebo-controlled trial to evaluate the efficacy and safety of two different doses of GHX02, compared with placebo, for acute bronchitis. One-hundred and fifty patients will be included in this trial and randomly assigned to either a high-dose GHX02 group(1920mg/day), standard-dose GHX02 group(960mg/day), or control group(placebo) in a 1:1:1 allocation ratio. Patients will take one of the medications three times a day for 7 days, with 3 visiting days(screening, day0, day7). On the screening day, the Korean Standard Tool of Pattern Identification of Cough and Sputum, a diagnostic system that determines therapy in Traditional Korean Medicine, will be used to allocate patients into three groups of wind-heat, wind-cold or others.

Outcome Measures

Primary Outcomes (1)

  • Change in BSS(Bronchitis Severity Score)

    BSS comprises the sum of five major symptom scores for acute bronchitis: cough, sputum, dyspnea, chest pain during coughing, and rales on auscultation. Each symptom is scored on a 4-point-scale (0=absent, 1=mild, 2=moderate, 3=severe, 4=very severe), with a maximum total score of 20 points. The investigator assesses symptom scores on the basis of the patient's subjective symptoms.

    Day0, Day7

Secondary Outcomes (5)

  • Change in Questionnaire of Clinical Symptoms of Cough and Sputum

    Day0, Day7

  • Change in Leicester Cough Questionnaire-acute(LCQ-acute)

    Day0, Day7

  • Change in frequency of coughing fits

    Day0, Day1, Day2, Day3, Day4, Day5, Day6, Day7

  • Integrative Medicine Outcome Scale(IMOS)

  • Integrative Medicine Patient Satisfaction Scale(IMPSS)
