Recruitment details
591 participants were randomized in the study. However, due to good clinical practice (GCP) compliance issues identified at one of the investigative sites, all 5 participants from that site were excluded from the study analyses.
Participants by arm
| Arm | Count |
|---|---|
| Dulaglutide 1.5 mg Participants received 1.5 mg of dulaglutide given weekly SC during the 52-week treatment period. Dulaglutide will be given alone or in combination with 1 OAM. Participants on DPP-4i discontinued DPP-4i at randomization and was regarded as monotherapy of dulaglutide, other OAMs continued at same dose during study period and were regarded as combination therapy with dulaglutide. | 391 |
