A Phase 2 interventional study of GHX02 and Placebo in Acute Bronchitis, sponsored by Daejeon University. Status unknown at 1 site in Korea, Republic of. Open to participants aged 19 Years to 75 Years. Per ClinicalTrials.gov, last updated 2019-03-05.

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.
156 studies on the registry are indexed under Bronchitis; 21 are open to participants now.
This study's planned enrollment of 150 is below the median of 185 across 105 interventional studies indexed under Bronchitis.

Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.
Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.
Chronic obstructive pulmonary disease: long-term lung disease that makes it hard to breathe out, including emphysema and chronic bronchitis.
Two enzymes measured in a routine blood test of the liver. Higher levels can mean the liver is under strain or damaged. SGPT and SGOT are older names for ALT and AST.
Criteria usually give a limit as a multiple of the upper limit of normal (ULN), often higher when cancer has spread to the liver.
Judged by the study doctor to matter for your health or for the study. It is a doctor’s decision, so ask the study team if you are unsure whether something counts.

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.
Time frame: Day0, Day7
Change in Questionnaire of Clinical Symptoms of Cough and Sputum
Questionnaire items are as follows: (1) cough -frequency, intensity, sensitivity; (2) sputum -frequency, volume, difficulty to cough-up, appearance, color; (3) activities of daily living; (4) night-time sleeping. Each item is scored on a 4-point-scale, with a total maximum score of 40 points.
Time frame: Day0, Day7
Change in Leicester Cough Questionnaire-acute(LCQ-acute)
It consists of 19 items divided into three parts, physical, psychological, and social, each scored from 1 to 7. The total score is the sum of the average scores(1-7 points) for each part. The higher the score, the better the quality of life.
Time frame: Day0, Day7
Change in frequency of coughing fits
participants will be classified into one of the following scales: 0 = 0 time/day, 1 = 1 time/day, 2 = 2-3 times/day, 3 = 4-5 times/day(sometimes), 4 = 6-10 times/day(frequent), 5 = over 15 times/day(consistently).
Time frame: Day0, Day1, Day2, Day3, Day4, Day5, Day6, Day7
Integrative Medicine Outcome Scale(IMOS)
It's a 5-point-scale for evaluating improvement after treatment (where, 1=complete recovery, 2=major improvement, 3=slight-to-moderate improvement, 4=no change, 5=deterioration), either by the patient or investigator (the investigator in this trial).
Time frame: Day7
Integrative Medicine Patient Satisfaction Scale(IMPSS)
It's a 5-point-scale for evaluating patient satisfaction with the treatment (where, 1=very satisfied, 2=satisfied, 3=neutral, 4=dissatisfied, 5=very dissatisfied)
Time frame: Day7
