bioequivalence study of combination tablets of saxagliptin / dapagliflozin / metformin xr (extended-release) and dapagliflozin / metformin xr relative to individual components in healthy subjects

Conditions: Type 2 Diabetes Mellitus

Summary: in this integrated, phase i study, the safety, tolerability, food effect, and pharmacokinetic (pk) properties of fixed-dose combination tablets of saxagliptin / dapagliflozin / metformin xr and dapagliflozin / metformin xr relative to individual components in healthy subjects will be investigated.

this study will be an open-label, randomized, 3-period, 3-treatment, single-dose crossover study in healthy subjects (males and females), performed at a single study center, conducted in 3 cohorts. a total of 126 healthy male or female subjects (3 cohorts of 42 subjects each \[each cohort consisting of 3 treatments\]) will be randomized in this study to ensure that at least 108 subjects (36 in each cohort) are evaluable. each subject will receive 3 single-dose treatments, and each treatment will be administered within 1 of the 3 successive treatment periods. within each cohort, subjects will be randomized to 1 of 6 treatment sequences with 7 subjects prescribing the ordered sequence of 3 administered treatments in each treatment sequence, and will receive the imps in either a fasted or fed-state according to the assigned treatment. for fed-state cohorts, all doses of study drug will be administered to subjects after consuming a standard meal (light fat, low calorie) in the morning. subjects will start consuming the meal 30 minutes prior to the dose and will finish the meal within 25 minutes. dosing will then start after 30 minutes after the start of the meal. subjects in the fasted state cohort will be fasted overnight (at least 10 hours) before dosing the study will comprise: * a screening period of maximum 28 days; * three treatment periods during which subjects will be resident in the unit from the day before dosing with the imp (day -1) until at least 72 hours after dosing; discharged on the morning of day 4; and * a final follow-up visit within 5 to 7 days after the last administration of the imp. there will be a minimum washout period of 7 to 14 days between each dose administration

administration. * documentation of irreversible surgical sterilization by hysterectomy, bilateral oophorectomy or bilateral salpingectomy but not tubal ligation. 3.2. or, if of childbearing potential: * must have a negative serum pregnancy test (minimum sensitivity 25 iu/l or equivalent units of human chorionic gonadotropin) at screening and within 24 hours prior to first imp administration. * must

throughout the study and for up to 90 days after the last dose of imp. 4. sexually active fertile male subjects must use effective birth control for the entire study and 90 days after the last dose of imp if their partners are women of childbearing potential. 5. have a body mass index (bmi) between 18 and 32 kg/m2 inclusive and weigh at least 50 kg and no more than 100 kg inclusive. exclusion criteria: * subjects will not enter the study if any of the following exclusion criteria are fulfilled: 1. history of any clinically significant disease or disorder which, in the opinion of the pi,

first imp dosing) gastrointestinal disease that may impact drug absorption and affect the pk of the study drugs. additionally, any gastrointestinal surgery (e.g., partial gastrectomy, pyloroplasty)

or donation of plasma (except at the screening visit) within 4 weeks of first imp dosing. 5. blood transfusion within 4 weeks of first imp dosing. 6. inability to tolerate oral medication. 7. inability to tolerate venipuncture or inadequate venous access as determined by the investigator. 8. recent (within 6 months of first imp dosing) drug or alcohol abuse as defined in the diagnostic and statistical manual of mental disorders, fourth edition (dsm-iv), diagnostic criteria for drug and alcohol abuse. 9. subjects who drink more than 3 cups of coffee or other caffeinecontaining products a day, or 5 cups of tea a day. 10. use of tobacco-containing or nicotine-containing products (including but not limited to cigarettes, pipes, cigars, chewing tobacco, nicotine patches, nicotine lozenges, or nicotine gum) within 6 months prior to first check-in (day -1, treatment period 1), or a positive nicotine test (i.e., cotinine) at screening and/or check-in. 11. history of diabetes
