- Primary Outcome Measures
Name Time Method Standard PK Parameter: Time at Which Cmax Was Observed (Tmax) Day 1 (at 0, 1, 1.5, 2, 3, 4, 6, 8, 12 hr), Day 2 (0 hr) and Day 7 (0, 0.5, 1, 1.5, 2, 4, 6, 8, 12 and 24 hr) PK parameters were calculated using data at the actual time of blood collection. Tmax was determined from plasma concentration-time data, using standard model independent methods.
Standard PK Parameter: Total Clearance (CL/F) Day 1 (at 0, 1, 1.5, 2, 3, 4, 6, 8, 12 hr), Day 2 (0 hr) and Day 7 (0, 0.5, 1, 1.5, 2, 4, 6, 8, 12 and 24 hr) PK parameters were calculated using data at the actual time of blood collection. CL/F was determined from plasma concentration-time data, using standard model independent methods.
Standard PK Parameter: Apparent Volume of Distribution (Vz/F) Day 1 (at 0, 1, 1.5, 2, 3, 4, 6, 8, 12 hr), Day 2 (0 hr) and Day 7 (0, 0.5, 1, 1.5, 2, 4, 6, 8, 12 and 24 hr) PK parameters were calculated using data at the actual time of blood collection. Vz/F was determined from plasma concentration-time data, using standard model independent methods.

R\[Cmax\], Ro and Rs were determined from plasma concentration-time data, using standard model independent methods. R\[Cmax\] = Cmax (Day 7)/Cmax (Day 1), Ro = AUC(0-tau) (Day 7)/ AUC(0-tau) (Day 1) and Rs = AUC(0-tau) (Day 7)/ AUC(0-inf) (Day 1).
DPP-IV Activity Weighted Mean AUCs at Baseline (Day -1) and Day 7 Baseline (Day -1) and Day 7 For analysis of DPP-IV activity, approximately 2 mL of whole blood was collected into a vacuum tube containing EDTA2K and centrifuged at approximately 4 degree Celsius, at approximately 2500 rpm for 15 minutes. Samples were stored in a freezer at -70 degree Celsius or lower. Double-delta represented active treatment within participant change from Baseline summarized across participants, subtracted from placebo within participant change from Baseline summarized across participants. AUC with respect to these time interval was calculated using linear trapezoidal rule by sum of the areas between each chronological pair of assessments (using observed times). Weighted mean was then determined by dividing AUC by observed length of collection interval (time of last assessment - time of first assessment in hr). Double-delta analysis has been presented in analysis. Unit of measure: Nano mole per minute per milliliter (nmol/min/mL).

Double-delta represented the active treatment within participant change from Baseline summarized across participants, subtracted from placebo within participant change from Baseline summarized across participants. AUC with respect to these time interval was calculated using linear trapezoidal rule by sum of the areas between each chronological pair of assessments (using observed times). Weighted mean was then determined by dividing AUC by observed length of collection interval (time of last assessment - time of first assessment in hr).

Samples were stored in a freezer at -70 degree Celsius or lower. Double-delta represented the active treatment within participant change from Baseline summarized across participants, subtracted from placebo within participant change from Baseline summarized across participants.

- Secondary Outcome Measures
Name Time Method Number of Participants With Adverse Events (AEs) and Serious Adverse Events (SAEs) Up to post-study screen (Follow-up [7 days after the last dose of study medication]) AE is defined as any untoward medical occurrence in a participant, temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease (new or exacerbated) temporally associated with the use of a medicinal product. SAE is any untoward medical occurrence that, at any dose results in death, is life-threatening, requires hospitalization or prolongation of existing hospitalization, results in persistent or significant disability/incapacity, is a congenital anomaly/birth defect, is serious corresponding to those listed in above definition.
