Outcome results
Change in Gastric Emptying Rate From Baseline as Determined by the Area Under the Curve (AUC) of the Gastric Emptying Rate
Change from baseline in gastric emptying rate was determined by the AUC by Gastric Emptying Breath Test (GEBT) at Day 28 after administration of PCS12852 or placebo.
Time frame: ~28 days
Population: The change from baseline to Day 28 in AUC was analyzed using an analysis of covariance (ANCOVA) model with fixed effects for treatment group and gastroparesis type (idiopathic gastroparesis \[IG\] or diabetic gastroparesis \[DG\]) and the baseline value as a continuous covariate. Only patients with a baseline and Day 28 value were included in the analysis. The parameters listed are the best comparison of the breath test as opposed to individual timepoints.
