Trial design

CTIS Part I — objectives, methods, condition coding

Main objective

Scope: Therapy

Assessment of non-inferiority of Test vs. Reference 1 with regard to the change in Bronchitis Severity Score (BSS) in patients with acute bronchitis after 7 days of treatment
Assessment of non-inferiority of Test vs. Reference 2 with regard to the change in Bronchitis Severity Score (BSS) in patients with acute bronchitis after 7 days of treatment

Secondary objectives 7

  1. Assessment of superiority of Test vs. Reference 1 with regard to the change in Bronchitis Severity Score (BSS) in patients with acute bronchitis after 7 days of treatment
  2. Assessment of superiority of Test vs. Reference 2 with regard to the change in Bronchitis Severity Score (BSS) in patients with acute bronchitis after 7 days of treatment
  3. Descriptive evaluation of differences in the change of BSS, between the Test product and each of the Reference products over the entire observation period between baseline and post-baseline visits
  4. Descriptive evaluation of differences in cough severity (CS) determined using Visual Analogue Scale (VAS), between the Test product and each of the Reference products over the entire observation period between baseline and post-baseline visits
  5. Descriptive evaluation of differences in CS determined using Verbal Category Descriptive (VCD) score, between the Test product and each of the Reference products over the entire observation period between baseline and post-baseline visits
  6. Descriptive evaluation of global efficacy of all treatments assessed at post-baseline visits V6, V7 and V8 by patient and investigator
  7. Descriptive evaluation of safety of all treatments over the entire observation period including Adverse Events and descriptive evaluation of global tolerability of all treatments assessed at post-baseline visits V6, V7 and V8 by patient and investigator

Endpoints

Primary and secondary outcome measures (English text)

Primary endpoints 1

  1. Change of BSS between visit V1 (baseline) and visit V6 (7 days of treatment)

Secondary endpoints 6

  1. Change of BSS between visit V1 (baseline) and each post-baseline visit V2, V3, V4, V5, V7, and V8 as well as baseline adjusted AUC
  2. BSS at each post-baseline visits V2 to V8 and change of BSS between visit V1 (baseline) and post-baseline visits V2, V3, V4, V5, V7, and V8, and related AUCs
  3. CS assessed on VAS between visit V1 (baseline) and post-baseline visits (Area under the curve (AUC) generated with VAS values between visit V1 (baseline) and post-baseline visits V2, V3, V4, V5, V6, V7, and V8 as well as baseline adjusted AUC)
  4. CS assessed on VAS at each post-baseline visit and change of CS-VAS between visit V1 (baseline) and post-baseline visits, and related AUCs.
