Official Title:	A 52-Week International, Multi-Centre, Randomised, Parallel-Group, Double-Blind, Active-Controlled, Phase III Study With a 52-Week Extension Period to Evaluate the Efficacy and Safety of Dapagliflozin in Combination With Metformin Compared With Sulphonylurea in Adult Patients With Type 2 Diabetes

Further study details as provided by AstraZeneca:

Primary Outcome Measures:

To examine whether the absolute change from baseline in HbA1c level with dapagliflozin plus metformin is non-inferior to glipizide plus metformin in patients with type 2 diabetes who have inadequate glycaemic control on metformin therapy alone [ Time Frame: 52 weeks ] [ Designated as safety issue: No ]

Secondary Outcome Measures:

To show that dapagliflozin plus metformin reduces body weight compared to glipizide plus metformin [ Time Frame: after 52 weeks treatment ] [ Designated as safety issue: Yes ]
To show that dapagliflozin plus metformin treatment leads to fewer patients with hypoglycaemic events compared to glipizide plus metformin [ Time Frame: after 52 weeks of treatment ] [ Designated as safety issue: Yes ]

Estimated Enrollment:	746
