Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Main Objective: 1. To assess the effect of up-titration of metformin plus the addition of sitagliptin compared with the up-titration of metformin alone on reduction from baseline in A1C. 2. To assess the overall safety and tolerability of up-titration of metformin plus the addition of sitagliptin compared to up-titration of metformin alone. ; Secondary Objective: 1. To assess the overall safety and tolerability of up-titration of metformin plus the addition of sitagliptin compared to up-titration of metformin alone. 2. To assess the effect of up-titration of metformin plus the addition of sitagliptin compared to up-titration of metformin alone on reduction from baseline in fasting plasma glucose. 3. To assess the proportion of subjects with baseline A1C = 8.5% that are at the A1C goal of <7% (<53 mmol/mol) with up-titration of metformin plus the addition of sitagliptin compared with the up-titration of metformin alone. 4. To assess the proportion of subjects receiving glycemic rescue therapy with up-titration of metformin plus the addition of sitagliptin compared with the up -titration of metformin alone. ;Primary end point(s): A1C – change from baseline at Week 20;Timepoint(s) of evaluation of this end point: Week 20 | — |
