The primary objective of the study is to assess the effect of dapagliflozin on the amount of glucose in the blood and urine when dapagliflozin is administered once a day (10 mg) versus twice a day (5 mg every 12 hours) after five days of dosing.

Condition Intervention Phase
Healthy Volunteers
Drug: Dapagliflozin
Phase 1

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Crossover Assignment
Masking: Open Label
Primary Purpose: Basic Science
Official Title: An Open-label, Randomised, Two-period Crossover Study to Assess the Effect of Dapagliflozin on Percent Inhibition of Glucose Re-absorption When Administered Once a Day (10 mg OD) Versus Twice a Day (5 mg BID) in Healthy Male and Female Volunteers

Further study details as provided by AstraZeneca:

Primary Outcome Measures:
  • Calculation of derivation of pharmacokinetic variables [ Time Frame: Up to 14 blood samples will be obtained on day 1 (with the closest interval between samples being 15 minutes), one sample on days 3 and 4, and up to 21 samples on day 5 ]

Secondary Outcome Measures:
  • Calculation of derivation of pharmacodynamic variables (inhibition of plasma glucose re-absorption, 24 hour urine glucose excretion, inhibition of rate of gut glucose absorption by measuring plasma glucose, insulin and GIP). [ Time Frame: plasma glucose will be drawn on Day 5, creatinine will be drawn at pre-dose of Day 4 and of Day 5, glucose and insulin will be drawn on Day 5 , Day 5 for GIP, urine will be collected on Day 5 in 4-hour intervals ]
  • To examine the safety and tolerability of the combination of dapagliflozin and metformin [ Time Frame: Adverse events and laboratory variables assessed throughout both 5-day treatment periods, and a follow-up visit 5-10 days later ]
