Part B will investigate the effects of 14d of co-dosing of GSK1292263 BID, 50mg BID of sitagliptin or placebo to 48 T2DM subjects taking metformin.

    An AE is defined as any untoward medical occurrence in a participant or clinical investigation 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. An SAE is defined as any untoward medical occurrence that, at any dose, results in death, is life threatening, requires hospitalization or prolongation of existing hospitalization, results in disability/incapacity, is a congenital anomaly/birth defect, may jeopardize the participant or require medical or surgical intervention to prevent one of the other outcomes listed in the definition above, or is an event of possible drug-induced liver injury.

    Blood samples were collected on Days -1 and 14, post-breakfast at 0.5, 1, 1.5, 2 and 3 hours post dose. For lunch (approximately 4 hours post morning dose) samples were collected at the following times after starting each meal: 0.5, 1, 1.5, 2 and 3 hours. For the evening meal (approximately 10 hours post morning dose), samples were taken at 0.5, 1, 1.5, 2 and 3 hours post dinner.

  36. Mean Post Meal Insulin Value (Part B)

    Time frame: At pre-breakfast on Days -1 and 14, and then at 0.5, 1, 1.5, 2 and 3 hours post dose.

  37. Change From Baseline in Weighted Mean for Glucose Value (Part B)

    Time frame: Baseline and at pre-breakfast on Days -1 and 14, and then at 0.5, 1, 1.5, 2 and 3 hours post dose.

    Baseline was considered to be Day -1 pre-breakfast value. The change from Baseline was calculated by subtracting the Baseline values from the individual post-randomization values. If either the Baseline or post-randomization value was missing, the change from Baseline is set to missing as well. If measurements were taken in triplicate, then the mean of the triplicate measurements was used as the Baseline. Weighted mean were assessed for (0-12) and (0-24). AUC with respect to that time interval was calculated using the linear trapezoidal rule. The weighted mean was determined by dividing the AUC by the observed length of the collection interval (time of last assessment - time of first assessment in hours). In order for the AUC to be calculated, the first and last time points and at least one additional assessment falling between the two must be non-missing.

  38. Change From Baseline in Weighted Mean for Insulin Value (Part B)

  39. Number of Participants With Relationship Between GSK1292263 Drug Exposures and Pharmacodynamic Parameters (Part B)

    Time frame: At pre-breakfast on Days -1 and 14, and then at 0.5, 1, 1.5, 2 and 3 hours post dose
