Renal Impairment Study With ASP1941

Inclusion criteria

• Patient with stable type 2 diabetes mellitus or healthy subject
• Subject must have pre-dose estimated Glomerular filtration rate (GFR) values (Modification of diet in renal disease (MDRD) method) at screening of:

• >90 (normal renal function)
• 60-90 (mild renal impairment)
• 30-60 (moderate renal impairment)
• 15-30 (severe renal impairment)
• BMI between 25.0-40.0 kg/m2, inclusive
• Fasted plasma glucose (FPG) <11.5 mmol/l (type 2 DM patients) or >5.6 mmol/l (Healthy volunteers)

Exclusion criteria

• Patients with Type 1 diabetes
• Pulse <40 or >90; SBP >160 mmHg; DBP > 100 mmHg
• T2DM patients who are not on a stable regimen for their current medication (1 month or 5 half lives, whichever is longer) to control their disease
• Healthy Volunteers: Any of the liver function tests above the upper limit of normal
• T2DM: The liver function tests should be within the following ranges:

• AST/ALT: <2 x ULN
• Bilirubin: <1.5 x ULN
• Alk Phos: < 1.5 x ULN
• Patients with renal impairment who have a history of a clinically significant illness (other than renal diseases and T2DM and associated clinical symptoms), medical condition, or laboratory abnormality within 3 months prior to screening
• Patients with renal impairment who have not been on a stable dose of concomitant medications for at least 2 weeks for at least 2 weeks (or 5 halflives, whichever is longer) and/or for whom dose changes are likely to occur during the study
• Patients with T2DM treated with a diet only
• T2DM patients with recent evidence (e.g within the last 6 months) of severe hypoglycemia, for example plasma glucose < 3mmol/l (<55 mg/dl), help from others to resolve the hypo or requiring hospitalization
• T2DM patients with a Hemoglobin value < 9 g/dl (5.6 mmol/l)
