A Study to Evaluate the Pharmacokinetics, Pharmacodynamics and Safety of ASP8232 in Subjects With Renal Impairment and in Type 2 Diabetes Mellitus Subjects With Chronic Kidney Disease

• Status: Completed
• Trial end date: 2014-09-09
• Target enrollment: 0
• Participant gender: All

Summary

This study consists of two parts.

Part 1 evaluates the effect of renal impairment on the PK and PD of a single dose of ASP8232. In addition, the safety and tolerability will be assessed.

Part 2 evaluates the PK, PD, and safety and tolerability of multiple doses of ASP8232 compared with placebo in Type 2 Diabetes Mellitus (T2DM) subjects with Chronic Kidney Disease (CKD).
