A Study to Assess the Effect of Ceftobiprole on the PK of Pitavastatin and on Plasma Levels of Coproporphyrin
brief summary
The goal of this clinical study was to determine the effect of the test drug ceftobiprole (a drug approved for the treatment of bacterial infections) on the elimination of pitavastatin (a drug approved for the treatment of increased levels of cholesterol in blood) from the body. This interaction was investigated by pharmacokinetic (PK) assessments. The clinical study also investigated the safety of ceftobiprole and how well ceftobiprole was tolerated by healthy subjects when it was administered in combination with pitavastatin.
detailed description
This study assessed whether there was an inhibitory effect of ceftobiprole on hepatic organic anion-transporting polypeptide 1B (OATP1B) activity. Pitavastatin was used as an OATP1B substrate in this study. The pharmacokinetics of oral pitavastatin were assessed when administered alone and when administered together with IV ceftobiprole in a study design including 2 treatment periods. In addition, the pharmacodynamic effect of repeated doses of IV ceftobiprole on the diurnal plasma levels of coproporphyrin I (CP-I) was assessed in this study as CP-I is an endogenous biomarker for hepatic OATPB1 activity.
The study duration was up to 38 days.
