About this study

Official title: A Multi-center, Randomized, Double-blind, Active Control, Parallel, Phase 4 Clinical Trial to Evaluate the Efficacy and Safety of CANIUM Tab. in Acute Bronchitis Patients.

This study compared two oral medicines containing Pelargonium sidoides extract in patients aged 12 to 75 years with acute bronchitis. Participants were randomly assigned to DSP2505 (Ckanium tablets) or Umckamin tablets for 7 days. The main question was whether DSP2505 was no worse than Umckamin by more than a defined margin in improving bronchitis symptoms. Symptoms, cough-related quality of life, overall improvement, satisfaction, and safety were assessed.

Read the detailed description

This phase 4, multicenter, randomized, double-blind, double-dummy, active-controlled, parallel-group non-inferiority trial was conducted at 12 hospitals in the Republic of Korea. Eligible patients had acute bronchitis with onset within 48 hours before randomization and a Bronchitis Severity Score (BSS) of at least 5 at screening and baseline. Following a screening period of up to 2 days, participants were randomized 1:1 to DSP2505 or Umckamin for 7 days. Randomization was stratified by baseline BSS (<8 or >=8). Matching placebos maintained blinding. Assessments were performed at baseline and the Day 7 end-of-treatment visit.

The primary endpoint was change in BSS total score from baseline to Day 7. The clinical study report describes an analysis of covariance with treatment as a fixed effect and baseline BSS as a covariate. Non-inferiority was assessed by comparing the upper bound of the two-sided 95% confidence interval for the adjusted difference (DSP2505 minus Umckamin) with a margin of 1.10 points. The per-protocol set was the primary efficacy analysis population, with a supporting full-analysis-set analysis. Safety was assessed in participants who received at least one dose.

This registration was prepared after study completion and analysis of the results.

What is being measured

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

  1. Change From Baseline in Bronchitis Severity Score (BSS) Total Score at Day 7

    BSS is the sum of five symptom scores: cough, sputum, rales/rhonchi, chest pain during coughing, and dyspnea. Each is rated from 0 (absent) to 4 (very severe), giving a total of 0 to 20. Higher scores indicate greater symptom severity. Change is Day 7 minus baseline; a negative change indicates improvement.

    Measured: Baseline and Day 7

Secondary outcomes (18)
  1. Change From Baseline in BSS Cough Score at Day 7

    The cough component of BSS is rated from 0 (absent) to 4 (very severe). Change is Day 7 minus baseline; a negative change indicates improvement.

    Measured: Baseline and Day 7

  2. Change From Baseline in BSS Sputum Score at Day 7

    The sputum component of BSS is rated from 0 (absent) to 4 (very severe). Change is Day 7 minus baseline; a negative change indicates improvement.

    Measured: Baseline and Day 7

  3. Change From Baseline in BSS Rales/Rhonchi Score at Day 7

    The rales/rhonchi component of BSS is rated from 0 (absent) to 4 (very severe). Change is Day 7 minus baseline; a negative change indicates improvement.

    Measured: Baseline and Day 7

  4. Change From Baseline in BSS Chest Pain During Coughing Score at Day 7

    The chest pain during coughing component of BSS is rated from 0 (absent) to 4 (very severe). Change is Day 7 minus baseline; a negative change indicates improvement.

    Measured: Baseline and Day 7

  5. Change From Baseline in BSS Dyspnea Score at Day 7

    The dyspnea component of BSS is rated from 0 (absent) to 4 (very severe). Change is Day 7 minus baseline; a negative change indicates improvement.

    Measured: Baseline and Day 7

  6. Percentage of Participants With BSS Total Score Below 3 at Day 7

    Response defined as BSS total score <3 at Day 7.

    Measured: Baseline and Day 7

  7. Percentage of Participants With a BSS Total Score Reduction of at Least 7 Points

    Response defined as a reduction in BSS total score of at least 7 points from baseline to Day 7.

    Measured: Baseline and Day 7

  8. Percentage of Participants Meeting Both BSS Response Criteria

    Response defined as both a BSS total score <3 at Day 7 and a reduction of at least 7 points from baseline.

    Measured: Baseline and Day 7

  9. Change From Baseline in Cough Assessment Test (COAT) Total Score at Day 7

    COAT assesses cough frequency, interference with daily activities, sleep disturbance, fatigue, and airway hypersensitivity. Each of five items is scored from 0 to 4, giving a total of 0 to 20. Higher scores indicate greater cough-related impairment. Change is Day 7 minus baseline; a negative change indicates improvement.

    Measured: Baseline and Day 7

  10. Investigator-rated Global Improvement at Day 7

    The Integrative Medicine Outcome Scale (IMOS) rates change relative to baseline: 1=complete recovery, 2=major improvement, 3=slight to moderate improvement, 4=no change, and 5=deterioration. Lower scores indicate greater improvement. The distribution across the five categories is assessed.

    Measured: Day 7

  11. Percentage of Participants With Investigator-rated Global Improvement at Day 7

    The Integrative Medicine Outcome Scale (IMOS) rates change relative to baseline: 1=complete recovery, 2=major improvement, 3=slight to moderate improvement, 4=no change, and 5=deterioration. Lower scores indicate greater improvement. Improvement is defined as an IMOS rating of 1 or 2 by the investigator.

    Measured: Day 7

  12. Percentage of Participants With Participant-rated Global Improvement at Day 7

    The Integrative Medicine Outcome Scale (IMOS) rates change relative to baseline: 1=complete recovery, 2=major improvement, 3=slight to moderate improvement, 4=no change, and 5=deterioration.

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.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Change From Baseline in Bronchitis Severity Score (BSS) Total Score at Day 7 (time frame: Baseline and Day 7). 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?
