Reporting Groups
  Description
Saxagliptin 2.5 mg + Glyburide 7.5 mg The Saxagliptin 2.5 mg + Glyburide 7.5 mg group includes data from subjects randomized to receive coadministration of blinded saxagliptin 2.5 mg oral tablets and open-label glyburide 7.5 mg oral tables once daily. Open-label glyburide may have been down titrated by 2.5 mg once due to hypoglycemia as deemed necessary by the investigator.
Saxagliptin 5 mg + Glyburide 7.5 mg The Saxagliptin 5 mg + Glyburide 7.5 mg group includes data from subjects randomized to receive coadministration of blinded saxagliptin 5 mg oral tablets and open-label glyburide 7.5 mg oral tables once daily. Open-label glyburide may have been down titrated by 2.5 mg once due to hypoglycemia as deemed necessary by the investigator.
Placebo + Glyburide 7.5 mg The Placebo + Glyburide 7.5 mg group includes data from subjects randomized to receive coadministration of blinded placebo oral tablets, blinded glyburide 2.5 mg, and open-label glyburide 7.5 mg once daily. Open-label glyburide may have been down titrated by 2.5 mg once due to hypoglycemia as deemed necessary by the investigator. Blinded glyburide may have been uptitrated by 5 mg according to glycemic criteria provided it had not been previously down-titrated.
