Official title
A Phase I, Open-Label, Parallel-Group, Single Dose, Non-Randomized Study To Compare The Pharmacokinetics Of Each Individual Component (Topiramate And Phentermine) Of The Combination Product VI-0521 In Subjects With Mild, Moderate And Severe Renal Impairment To Subjects With Normal Renal Function
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
VI-0521, a fixed dose combination of immediate-release (IR) phentermine and controlled-release (CR) topiramate, is in Phase III clinical development as a potential therapy for obesity. In human, both phentermine and topiramate are primarily cleared by renal excretion. The contribution of hepatic metabolism to elimination of phentermine and topiramate is not significant. Obese patients, the proposed indicated population for future treatment with VI-0521, are likely to have renal impairment. Therefore, this study is important in understanding the effect of renal impairment on the pharmacokinetics of topiramate and phentermine in subjects with renal impairment compared to subjects with normal renal function.
