Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Main Objective: The primary objective is the efficacy of Neurexan® on tension and nervousness perception using visual analogue scales (VAS) when study participants undergo an emotional stressful condition as compared to Placebo. The test method for this study is the TSST protocol. ;Secondary Objective: Secondary objectives of the study are stress-sensitive psychological and physiological measures in response to acute stress: • stress-related biomarkers such as plasma and saliva cortisol, a-amylase, Adrenocorticotropic Hormone (ACTH), catecholamines, NK cells • parameters of Autonomous Nervous System (ANS) such as blood pressure (BP), heart rate and heart rate variability (HRV) • state anxiety and stress perception measured by State-Trait Anxiety Inventory (STAI) • physiological questionnaire (modified somatic SCL90);Primary end point(s): • Area under the curve (AUC) of VAS tension values from T1 until T15. • Area under the curve (AUC) of VAS nervousness values from T1 until T15. For each of the two AUCs an Analysis of Covariance (ANCOVA) model including gender and site as qualitative factors and the respective VAS value (i.e. tension or nervousness) at time point T1 (-210 min) as a covariate will be analysed to test for treatment differences ;Timepoint(s) of evaluation of this end point: -210 min -180 min -150 min -120 min -90 min -60 min -30 min -15 min +15 min +25 min +40 min +55 min +70 min +100 min | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary end point(s): • Changes in tension and nervousness VAS at all time points after time point T1 (-210 min) • Changes in plasma and saliva cortisol and a-amylase, ACTH, catecholamines norepinephrine (NE) and epinephrine (E) • Changes in NK cells (subgroup) • Changes in BP, heart rate and HRV • State anxiety and stress perception measured by STAI-X1 • Incidence of AEs All parameters will be descriptively summarised by treatment and assessment time. The AEs and vital signs will be summarised by treatment group. ;Timepoint(s) of evaluation of this end point: -60 min to +100 min, AEs from -180 min to +100 min | — |
