Study Overview
=================
Brief Summary
-----------------
Primary Objective: To study the effect of mild, moderate and severe renal impairment on the pharmacokinetics (PK) of Venglustat following a single dose. Secondary Objective: To assess the tolerability of Venglustat given as a single dose in subjects with mild, moderate and severe renal impairment in comparison with matched subjects with normal renal function.

Detailed Description
-----------------
Approximately 41 days, including a 21-day screening period, a 1-day treatment period, followed by a 9-day period of plasma sampling for assessment of primary endpoints.
