In patients receiving coadministered Linagliptin 2.5 mg/ Metformin 1000 mg twice daily as initial therapy 1*†
Secondary endpoint:
percent of patients who achieved A1C <7%‡

* Study Design: A randomized, double-blind, placebo-controlled, parallel-group study of drug-naïve or previously treated (4 weeks washout and 2 weeks placebo run-in) patients with type 2 diabetes with insufficient glycemic control (aged 18 to 80 years) who were randomized to placebo (n=72), linagliptin 5 mg once daily (n=142), metformin 500 mg twice daily (n=144), linagliptin 2.5 mg twice daily + metformin 500 mg twice daily (n=143), metformin 1000 mg twice daily (n=147), or linagliptin 2.5 mg twice daily + metformin 1000 mg twice daily (n=143). Primary endpoint was change from baseline A1C after 24 weeks of treatment. Secondary endpoints included change from baseline in FPG 2hPPG after 24 weeks of treatment. 29.2% of patients in the placebo group required use of rescue therapy vs 11.1% of patients receiving linagliptin 5 mg once daily, 13.5% of patients receiving metformin 500 mg twice daily, 8.0% of patients receiving metformin 1000 mg twice daily, 7.3% of patients receiving linagliptin 2.5 mg twice daily + metformin 500 mg twice daily, and 4.3% of patients receiving linagliptin 2.5 mg twice daily + metformin 1000 mg twice daily. Full analysis population using last observation on study.1
† Superiority of both free combination therapies, consisting of the twice-daily administration of linagliptin 2.5 mg and metformin (500 mg or 1000 mg), was shown over the individual metformin components (500 mg and 1000 mg, both twice daily) and over linagliptin 5 mg once daily for the change in A1C from baseline at week 24. Linagliptin 2.5 mg twice daily + metformin 1000 mg twice daily was superior to metformin 1000 mg twice daily (P<0.0001); linagliptin 2.5 mg twice daily + metformin 1000 mg twice daily was superior to linagliptin 5 mg once daily (P<0.0001); linagliptin 2.5 mg twice daily + metformin 500 mg twice daily was superior to metformin 500 mg twice daily (P<0.0001); linagliptin 2.5 mg twice daily + metformin 500 mg twice daily was superior to linagliptin 5 mg once daily (P<0.0001).
