What is being measured

The primary outcome is the main question the study is designed to answer.

  1. The rate of subjects whose symptoms improved based on the wheezing score at 3 days

    The rating was: 0=No wheezing (None); 1=mild (End expiration with stethoscope); 2=moderate (Inspiration and expiration with stethoscope) and 3=severe (Audible without stethoscope).

    Measured: 3 days treatment period

Secondary outcomes (5)
  1. The rate of subjects whose symptoms improved based on the wheezing score at 7 days

    Measured: 7 days treatment period

  2. The rate of subjects whose wheezing score improved by two or more grades at 3 and 7 days

    Measured: 3 and 7 days treatment period

  3. The change in bronchitis severity score excluding the sputum (BSSEs) at 3 and 7 days

    • The BSSEs comprises the following four symptoms typical for Acute Bronchitis: cough, chest pain on coughing, crackle and dyspnea. These symptoms are each assessed according to a 5-point Likert scale: 0 = absent, 1 = mild, 2 = moderate, 3 = severe and 4 = very severe

    Measured: 3 and 7 days treatment period

  4. The change in patient satisfaction scores for wheezing (VAS, Visual Analogue Scale) at 3 and 7 days

    VAS consists of a horizontal line, usually 100 in length and select a point on the scale indicating the level of satisfaction for wheezing in the 3 and 7 days. The number 0 indicates not satisfaction and 100 indicates very satisfaction.

    Measured: 3 and 7 days treatment period

  5. The change in patient satisfaction scores for cough (COAT, COugh Assessment Test) at 3 and 7 days

    All items can be scored as a single scale (0-4 scaling of each item, 0-20 total score range). Higher scores represent more severe cough.

    Measured: 3 and 7 days treatment period

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 5 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: looking for participants now, as of the sponsor's last update on 23 Sep 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

How can a doctor refer a patient or contact the research team?

Contact Hyeon Jong Yang, MD (+82-2-709-9390, ilove902@hanmail.net), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

The rate of subjects whose symptoms improved based on the wheezing score at 3 days (time frame: 3 days treatment period). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?
