Description of intervention(s) / exposure
Treatment: Drugs - Alogliptin
Treatment: Drugs - Metformin
Treatment: Drugs - Glipizide

Experimental: Metformin + Alogliptin 12.5 mg - Alogliptin 12.5 mg, tablets, orally, once daily and the maximum tolerated dose of metformin (1500 mg to 3300 mg daily) for up to 104 weeks.

Experimental: Metformin + Alogliptin 25 mg - Alogliptin 25 mg, tablets, orally, once daily and the maximum tolerated dose of metformin (1500 mg to 3300 mg daily) for up to 104 weeks.

Active Comparator: Metformin + Glipizide - Glipizide 5 mg, tablets, orally, once daily and the maximum tolerated dose of metformin (1500 mg to 3300 mg daily) for up to 104 weeks. After at least 2 weeks of treatment but prior to Week 20, participants with persistent hyperglycemia (fasting plasma glucose =250 mg/dL) underwent a dose titration of glipizide up to 20 mg in 5-mg increments in 4-week intervals.
