A Study to Evaluate the Food Effect on Drug Availability, Pharmacokinetic (PK) Properties, Safety and Tolerability of Two Different Dose Combination Therapy of Saxagliptin/Dapagliflozin/Metformin Extended-release (XR) Against Individual Component Co-administration.

A Study to Assess the Fed-state Bioequivalence of a Triple Fixed-Combination Drug Product (FCDP) of 2.5 mg Saxagliptin / 5 mg Dapagliflozin / 1000 mg Metformin XR and 5 mg Saxagliptin /10 mg Dapagliflozin /1000 mg Metformin XR Relative to Individual Components (Onglyza and XIGDUO XR) Co-administration. A randomized, open-label, cross over design has been chosen to minimize the effects of between-subject variability and any period effects on the overall results.

This study will be randomized, 3-period, 3-treatment, single-dose, open-label, single-center, crossover to assess the fed-state bioequivalence of a two triple Fixed-combination Drug Product (FCDP) of saxagliptin/dapagliflozin/metformin extended-release (XR) relative to individual components co-administered in approximately 84 healthy adult subjects. Eligible subjects will be healthy male and female aged 18 to 55 years, with a body weight of 50 to 100 kg and body mass index (BMI) of 18 to 32 kg/m2. Of the 84 randomized subjects (2 cohorts of 42 subjects each \[3 treatments in each cohort\]), at least 72 subjects (36 in each cohort) should be evaluable. Each randomized 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 to 6 treatment sequences prescribing the ordered sequence of 3 administered treatments with 7 subjects in each treatment sequence. The investigational medicinal product (IMPs) will be administered orally at single-dose to subjects within 5 minutes after standard meal (light-fat, low-calorie) in the morning (fed condition) or following a 10 hour fast (fasted condition). In both cohorts, test product will be compared with treatments of fed and fasted conditions Subjects in Cohort 1 will be randomized to one of the treatment sequences (ABC), (ACB), (BAC), (BCA), (CAB) or (CBA).

Treatment A (Reference Product under fed conditions) - Single-dose of 2.5 mg saxagliptin (ONGLYZA) and 5 mg dapagliflozin / 1000 mg metformin XR (XIGDUO XR) tablets.

Treatment B (Test Product under fed conditions) - Single-dose of triple FCDP consisting of 2.5 mg saxagliptin / 5 mg dapagliflozin / 1000 mg metformin XR.

Treatment C (Test Product fasted conditions) - Single-dose of triple FCDP tablet consisting of 2.5 mg saxagliptin / 5 mg dapagliflozin / 1000 mg metformin XR.

Subjects in Cohort 2 will be randomized to one of the treatment sequences (DEF), (DFE), (EDF), (EFD), (FDE) or (FED).

Treatment D (Reference product under fed conditions) - Single-dose of 5 mg saxagliptin (ONGLYZA) and 10 mg dapagliflozin / 1000 mg metformin XR (XIGDUO XR) tablet.

Treatment E (Test Product under fed conditions) - Single-dose of triple FCDP consisting of 5 mg saxagliptin / 10 mg dapagliflozin / 1000 mg metformin XR.

Treatment F (Test Product under fasted conditions) - Single-dose of triple FCDP consisting of 5 mg saxagliptin / 10 mg dapagliflozin / 1000 mg metformin XR.

The study will comprise:

* A screening period of maximum 28 days;
* Three resident treatment periods - Day before dosing with the IMP (Day -1) until at least 72 hours after dosing; and will be discharged on the morning of Day 4; and
* A follow-up visit within 5 to 7 days after the last dose of IMP. Treatment periods will be separated by a minimum washout period of 7 to 14 days between each IMP dose. The duration of the study will be approximately 7 to 9 weeks.
