Inclusion Criteria:

Inclusion criteria - Type-2 Diabetes Patients

  • Male or female patients aged 30 to 75 years with Type-2 Diabetes Mellitus (T2DM) and who are in otherwise good health
  • Must have been diagnosed with T2DM at least 6 months prior to screening, and whose diabetes is controlled by diet and exercise alone or by stable dosage ( > 3 months) of metformin
  • HbA1c in the range of 6.5% to 9% at screening

Inclusion Criteria - Healthy Volunteers

  • Male or female subjects aged 30 to 75 years, determined to be in good health
  • Normal oral glucose tolerance test (OGTT) at screening
  • Age, gender and weight matched to subjects with T2DM

Exclusion Criteria:

Exclusion criteria - Type-2 Diabetes Patients

  • A history of:
  • Type 1 diabetes, diabetes that is a result of pancreatic injury, or secondary forms of diabetes, e.g., Cushing's syndrome and acromegaly
  • Acute metabolic diabetic complications (such as ketoacidosis or hyperosmolar state (coma)) within the past 6 months
  • Torsades de Pointes, ventricular tachycardia or ventricular fibrillation
  • Any severe hypoglycemic episode within 3 months of screening
  • Use of any of the following medications:
  • Antihypertensive or lipid-lowering agents unless on a stable dose for at least 3 months prior to screening
  • Chronic insulin treatment (> 4 weeks of treatment in the absence of an intercurrent illness) within the past 6 months
  • Chronic oral/intramuscular/intravenous corticosteroid treatment ( > 7 consecutive days of treatment) within 8 weeks prior to screening

Exclusion Criteria - Healthy Volunteers

  • First degree relative of an individual with T2DM
  • History of gestational diabetes
  • Use of any prescription medication within 1 month prior to dosing. Use of over-the-counter medications or vitamins within 14 days prior to dosing.

Other protocol-defined inclusion/exclusion criteria may apply.
