Clinical Trial 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.

Description:

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
