General information about the trial
|
|||
Main objective of the trial |
The primary objective of the trial was to establish bioequivalence with respect to area under concentration versus time curve from zero to infinity after single dose administration (AUC), AUC from time zero to the last data point (AUC[0-tlast]) and maximum observed drug concentration (Cmax) of 20 milligrams (mg) granules for oral suspension versus 20 mg tablets rivaroxaban (BAY59-7939, Xarelto) when administered as single oral dose under fed conditions.
|
||
Protection of trial subjects |
The conduct of this clinical study met all local legal and regulatory requirements. The study was conducted in accordance with ethical principles that have their origin in the Declaration of Helsinki and the International Council for Harmonization guideline E6: Good Clinical Practice. Before entering the study, the informed consent was read by and explained to all the subjects. Participating subjects signed informed consent form and could withdraw from the study at any time without any disadvantage and without having to provide a reason for this decision. Only investigators qualified by training and experience were selected as appropriate experts to investigate the study drug.

Statistical analysis description |
Logarithms of AUC were analyzed using analysis of variance (ANOVA) including sequence, subject (sequence), period, and treatment effects. Based on these analyses point estimates (Least squares [LS] mean) and 90% confidence intervals (CIs) for the treatment ratio: 20 mg granules for oral suspension/tablet were calculated by re- transformation of the logarithmic results given by the ANOVA. Database auto-calculates total number of subjects erroneously, analyzed number of subjects was 28.
