| E.2 Objective of the trial | 
| E.2.1 | Main objective of the trial  | 
| To show superiority of the 3 dulaglutide doses, including the two higher doses (4.5 mg and 3.0 mg) and the approved 1.5 mg dose to placebo in change in HbA1c. | 
 
 
 | 
| E.2.2 | Secondary objectives of the trial  | 
To determine if the two higher doses of Trulicity are effective and safe.
 Efficacy:  To compare each dulaglutide arm (4.5 mg, 3.0 mg, 1.5 mg) to the placebo arm at 18 weeks for secondary efficacy parameters.
 Safety:  To compare each dulaglutide arm (4.5 mg, 3.0 mg, 1.5 mg) to the placebo arm for selected safety parameters at 18 weeks.
 PK/PD:  To characterize the pharmacokinetics (PK) of  dulaglutide and establish the relationships between dose/exposure and key safety and efficacy measures. |
