| E.2.1 | Main objective of the trial | 
| To evaluate the dose-response relationship for LIK066 in terms of changes from baseline in HbA1c after 12 weeks of treatment across 7 oral doses (2.5 mg, 5 mg, 10 mg, 25 mg, 50 mg, 100 mg, or 150 mg q.d.) of LIK066 or placebo. |  | 
| E.2.2 | Secondary objectives of the trial | 
| 1.	To evaluate the effect of LIK066 on: •	fasting plasma glucose (FPG)
 •	urinary glucose-to-creatinine ratio (UGCR)
 •	renal threshold for glucose excretion (RTg)
 •	body weight
 •	systolic and diastolic blood pressure
 •	postprandial glucose, beta cell function, insulin secretion relative to glucose (ISR/G), oral glucose insulin sensitivity (OGIS), GLP-1 and PYY response during a meal test
 
 2.	To evaluate the safety and tolerability of LIK066
