BMS - Safety, Pharmacokinetics (PK) and Pharmacodynamics (PD) of Dapagliflozin in Type 1 Diabetes

7-PGM was measured as milligrams per deciliter (mg/dL) by a central laboratory. Baseline was defined as the assessment on Day -1, prior to the start date and time of the first dose of the double-blind study medication. 7-PGM included the average of all available glucose values before and 2-hour (hr) after each meal (breakfast, lunch, dinner) as well as bedtime. Measurements were on Day -1, and Day 7 in the double-blind period.

Serial blood samples were collected predose 0 hr, and hr 0.5, 1, 2, 3, 4, 6, 8, 12, and 24 in the double-blind period. Individual subject PK parameter values were derived by non-compartmental methods by a validated PK analysis program, Kinetica®. Actual sampling times were used for PK calculations and nominal times were used for generation of mean plasma concentration-time plots and summaries. Pre-dose sample collection times were changed from negative numbers (based on elapsed time to dose) to zero for the purpose of calculating PK parameters. The Cmax was recorded directly from experimental observations.

Pre-dose sample collection times were changed from negative numbers (based on elapsed time to dose) to zero for the purpose of calculating PK parameters. The concentrations below the lower limit of quantitation (<LLOQ) were set as "missing" for the calculation of PK parameters as well as summary statistics. AUC[TAU], was calculated by a mixture of logand linear-trapezoidal summations.

MR was calculated as the ratio of metabolite to parent AUC(TAU), corrected for molecular weights of dapagliflozin and dapagliflozin 3-O-glucuronide (408.82 and 584.99, respectively).
