Participants were randomized 1:1 to placebo or riociguat in individualized doses (maximum of 2.5?mg three times daily) during an 8-week titration period, followed by an 8-week stable dosing period. This was followed by an optional 16-week open-label extension phase for participants with active DU/reoccurrence of DUs within 1?month of the end of the main treatment phase. The primary endpoint was the change from baseline to week 16 in online ulcer burden (NUB), analyzed using ANCOVA. Additional endpoints included plasma biomarkers and proportion of participants with treatment-emergent adverse events (AEs). Results Seventeen participants (eight placebo, nine riociguat) were randomized at five centers. Six participants in each group transitioned to the open-label extension. Baseline characteristics were comparable between the treatment groups, except PMSF participants randomized to placebo were older and experienced longer disease duration (test. If a statistically significant would be observed in our small study, it might need to be replicated in a larger confirmatory study. Statistical analysis Continuous variables were summarized using means, standard deviations (SD), median, interquartile range (IQR), and range, and PMSF qualitative variables were summarized using counts and percentages. Mean (SD) is definitely reported, unless otherwise noted. The primary and secondary effectiveness endpoints were analyzed using the revised intention-to-treat human population (MITT), defined as all participants randomized, receiving at least one dose of treatment, and having at least one post-baseline effectiveness assessment. Like a level of sensitivity analysis, the primary endpoint was also analyzed using the per-protocol arranged, defined as the MITT human population who did not have a major protocol violation. For the primary analysis, changes in NUB were compared in the two treatment organizations using an ANCOVA model, with terms for treatment group and baseline NUB value. Distributional assumptions were assessed. Analysis for secondary end result actions that are continuous was performed using a related approach as that for the primary endpoint. For analyses of discrete secondary results measures, we used Fishers exact checks. Poisson regression was utilized for end result measures that were counts (e.g., quantity of AEs) and log-rank checks, and Kaplan-Meier plots were utilized for time-to-event results. Plasma biomarker changes from baseline (week 0) to week 16 were analyzed using the ANCOVA model. Security analyses were performed within the security analysis set which included all participants who have been randomized and received at least one dose of the study drug. Statistical checks were conducted in the 0.05 significance level (with no adjustments for multiplicity) using two-tailed tests. Statistical analyses were performed using SAS version 9 or higher.
