Design outcomes

Primary

MeasureTime frame
Main Objective: To assess the efficacy of an 8-day treatment with carbabenzpyride in adult subjects with influenza A in three different dosages compared to placebo on the basis of the duration of illness in terms of alleviation of symptoms.;Secondary Objective: To assess the safety of three different doses of carbabenzpyride compared to placebo in subjects with influenza A. To determine the dose with the best benefit / risk ratio for the treatment of influenza A.;Primary end point(s): The primary endpoint is defined as: Time to alleviation [days] of influenza symptoms from Day 1 (Visit 1) to Day 22 comparing different dosages of carbabenzpyride with placebo in the Full Analysis Set (FAS) population. The time to alleviation [days] of symptoms (cough, sore throat, nasal symptoms, headache, fatigue, myalgia, sweat and / or chill) will be calculated for a (maximum) observation period of 21 days (Day 1 to Day 22). Alleviation is defined as the start of a 24 ± 3 hour period, in which a symptom is less or equal to mild intensity (i.e. score = 1) and does not increase during that period. The analysis of the primary endpoint will be based on the subjects’ daily diary assessments. ;Timepoint(s) of evaluation of this end point: Continuously up to Day 22.

Secondary

MeasureTime frame
Secondary end point(s): 1. The AUC of all symptoms (sum of scores of all influenza symptoms) will be calculated from Day 1 to Day 22 as assessed by the subject in the diary and analyzed by the ANOVA with the factors “treatment” and “geographical regions“, and baseline as covariate using Dunnett’s test approach and tested for each active treatment group vs. placebo. In addition with the nonparametric Wilcoxon-Mann-Whitney test adjusted for “geographical regions” (van Elteren’s test) will be calculated. In order to show a dose-response relationship, also the Jonkheere-Terpstra test will be performed. 2. The duration of each individual symptom of influenza from Day 1 to Day 22 as assessed by the subject in the diary will be analyzed analogously to the primary endpoint. 3. The AUC of each individual symptom of influenza from Day 1 to Day 22 as assessed by the subject in the diary will be analyzed by the Wilcoxon test adjusted for “geographical regions” (van Elteren’s test) for each treatment group vs. placebo. 4. The AUC of all symptoms (sum of scores of all influenza symptoms) calculated from Day 1 to Day 22 for two subgroups, either with or without intake of paracetamol / acetaminophen during the course of the study will be analyzed by the ANCOVA with the factors “treatment” and “geographical regions“, and baseline as covariate using Dunnett’s test approach will be tested pairwise for each active treatment group vs. placebo. In addition, the nonparametric Wilcoxon test adjusted for “geographical regions” (Van Elteren’s test) will be calculated. 5. The AUC of virus titer per dose group from Visit 1 to Visit 5 will be log-transferred and analyzed by the ANCOVA with the factors “treatment” and “geographical regions“, and baseline as covariate using Dunnett’s test approach for each active treatment group vs. placebo. 6. The AUC of antibody response (HAI) from Visit 1 to Visit 6 will be log-transferred and tested by the ANCOVA with the factors “treatment” and “geographical
