| E.2.1 | Main objective of the trial |
1.To compare the effect of the addition of ertugliflozin with the addition of placebo, on the change in average blood sugar (haemoglobin A1C) from the study start (baseline) to 24 weeks.

|
|
| E.2.2 | Secondary objectives of the trial |
1. To compare the addition of ertugliflozin, with dosing optimized according to A1C response, to the addition of placebo on the change from baseline in A1C at 24 weeks.
2. To compare the addition of ertugliflozin 5 mg with the addition of placebo on the change from baseline in A1C at 24 weeks.
3. To compare the effect of the addition of ertugliflozin to the addition of placebo on the change from baseline in fasting plasma glucose (FPG) at 24 weeks.
4. To assess the within-group (ertugliflozin and placebo) changes from baseline at 54 weeks for A1C and FPG. |

| E.2.3.1 | Full title, date and version of each sub-study and their related objectives |
| Merck will conduct Future Biomedical Research on DNA (Blood) specimens collected during this clinical trial. Such research is for biomarker testing to address emergent questions not described elsewhere in the protocol (as part of the main trial) and will only be conducted on specimens from appropriately consented subjects. The objective of collecting specimens for Future Biomedical Research is to explore and identify biomarkers that inform the scientific understanding of diseases and/or their therapeutic treatments. The overarching goal is to use such information to develop safer, more effective drugs, and/or to ensure that subjects receive the correct dose of the correct drug at the correct time |
