Chronic Renal Insufficiency Clinical Trial
— STP237Official title:
Open Label, Phase I Study to Assess and Compare the Pharmacokinetic Parameters After Multiple Oral Administration of Stiripentol 1000 mg in Renal Impaired Patients and Matching Controls With Normal Renal Function
The purpose of this study is to determine whether the pharmacokinetics (PK) of stiripentol and of its relevant metabolites would be altered in subjects with renal impairment compared with normal controls in order to assess the need of dose adjustment in the renal impaired population. This study will include subjects with mild, moderate and severe renal impairment.
