E.5 End points |
E.5.1 | Primary end point(s) |
The primary efficacy variable is the sum score of the Bronchitis Severity Scale (BSS) taking into account the change/course of the sum score from start of treatment (Study Day 1) until Study Day 5 and Study Day 8. The BSS comprises the following criteria: cough, sputum production (expectoration), rales/rhonchi, chest pain when coughing and dyspnoea. Each of these 5 criteria is to be assessed by the investigator on a 5-step rating scale with the following steps: 0 = symptom not present, 1 = mild, 2 = moderate, 3 = severe, 4 = very severe. The BSS sum score is the sum of the scores for each of the 5 criteria.
|
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
|
E.5.2 | Secondary end point(s) |
Secondary efficacy variables are:
- The course of the scores for each of the individual criteria of the BSS (which are cough, sputum production (expectoration), rales/rhonchi, chest pain when coughing and dyspnoea) from start of treatment (Study Day 1) until Study Day 5 and Study Day 8. The criterion rales/rhonchi can be assessed only based on auscultation. Therefore this criterion is assessed by investigator, but not by the subject. Hence, the individual criteria of the BSS assessed by the subject include cough, sputum production (expectoration), chest pain when coughing and dyspnoea.
- Complete remission: a BSS sum score of ≤ 2: A sum score of the BSS ≤ 2 assessed by the investigator indicates complete remission.
- Severity of cough measured on a 100 mm Visual Analogue Scale (VAS) (ranging from 0 mm = no cough to 100 mm = worst cough ever) every day from inclusion (Study Day 1) to Study Day 8
- Body temperature (measured with ear thermometer) assessed by the investigator at inclusion (Study Day 1) and Study Day 8 and assessed by the subject every day from Study Day 2 to Study Day 7, inclusively
- Treatment failure: hospitalisation due to worsening of bronchitis and / or prescription and subsequent use of any available product for bronchitis/sinusitis/common cold
- Use of antibiotics
- Assessment of the efficacy of the study medication by investigator and by subject on a verbal rating scale: 3 = very good, 2 = good, 1 = satisfactory, 0 = bad
- Use of rescue medication
Safety Assessment:
- Adverse events
- General physical examination at inclusion and at Study Day 8
- Laboratory parameters: Haematology including erythrocyte count, platelet count, white blood cell count with differential white blood cell count (WBC), liver panel with gamma-glutamyl transferase (GGT), alanine aminotransferase (ALAT), aspartate aminotransferase (ASAT), alkaline phosphatase (ALP), creatinine, C-reactive protein (CRP), vitamin D (25OH).
- Assessment of the tolerability of the study medication by investigator and by subject on a verbal rating scale; 3 = very good; 2 = good; 1 = satisfactory; 0 = bad. |
