Screening details |
All randomized participants, except for 1, in the dulaglutide group, were treated with at least 1 dose of study drug and comprised the ITT population.

Percentage of Participants with Self-Reported Events of Hypoglycemia | |||||||||||||||||||||||||||

Hypoglycemic events (HE) were classified as severe (defined as episodes requiring the assistance of another person to actively administer resuscitative actions), documented symptomatic (defined as any time a participant feels that he/she is experiencing symptoms and/or signs associated with hypoglycemia, and has a plasma glucose level of =<3.9 mmol/L), asymptomatic (defined as events not accompanied by typical symptoms of hypoglycemia but with a measured plasma glucose of =<3.9 mmol/L), nocturnal (defined as any hypoglycemic event that occurred between bedtime and waking), or probable symptomatic (defined as events during which symptoms of hypoglycemia were not accompanied by a plasma glucose determination). Percentage is calculated as the number of participants reporting HE each visit/ the total number of participants reporting HE during the entire study treatment period.

Justification: The study was double-blinded and samples were collected from all participants. Those participants in the dulaglutide treatment group were tested for anti-drug antibody positive samples; placebo participants were not tested for ADA’s. |
