Least Squares Means (LS Means) of the HbA1c change from baseline to primary endpoint was adjusted by fixed effects of treatment, country, visit, treatment-by-visit interaction, participant as random effect and baseline HbA1c as covariate, via a Mixed-effects model for repeated measures (MMRM) analysis using restricted maximum likelihood (REML).

Participants who were randomized and received at least one dose of study drug with evaluable HbA1c data at both baseline and post-baseline.

The percentage of participants who achieved the target HbA1c values at endpoint will be analyzed with a repeated logistic regression model (the generalized estimation equation [GEE] model). The model includes country, treatment, visit and treatment interaction and baseline HbA1c as a continuous covariate.

Participants who were randomized and received at least one dose of study drug with evaluable HbA1c data.

LS Means of the FSG from baseline to primary endpoint was adjusted by fixed effects of treatment, country, baseline HbA1c strata, and baseline FSG as covariate, via Analysis of Covariance Model (ANCOVA) with Last Observation Carried Forward (LOCF).

Participants who received at least one dose of study drug and had evaluable FSG data at both baseline and post-baseline. LOCF was used to impute missing post-baseline values. If no data after date of randomization, the endpoint was considered missing.

LS Means of the body weight change from baseline to primary endpoint was adjusted by fixed effects of treatment, country, visit, treatment-by-visit interaction, participant as random effect and baseline body weight as covariate, via a MMRM analysis using REML.

Participants who received at least one dose of study drug and had evaluable body weight data at both baseline and post-baseline.

LS Means of the BMI change from baseline to primary endpoint was adjusted by fixed effects of treatment, country, visit, treatment-by-visit interaction, participant as random effect and baseline BMI as covariate, via a MMRM analysis using REML.

Participants who received at least one dose of study drug and evaluable BMI data at both baseline and post-baseline.

LS Means of the SMPG change from baseline to primary endpoint at week 24 was adjusted by fixed effects of treatment, country, visit, treatment-by-visit interaction, participant as random effect and baseline SMPG value as covariate, via a MMRM analysis using REML.

Participants who received at least one dose of study drug and had evaluable SMPG data at both baseline and post-baseline.

Information on cardiovascular (CV) risk factors was collected at baseline. Deaths and nonfatal cardiovascular adverse events (AEs) were adjudicated by an external committee of physicians with cardiology expertise. Nonfatal cardiovascular AEs to be adjudicated included myocardial infarction, hospitalization for unstable angina, hospitalization for heart failure, coronary interventions, and cerebrovascular events, including cerebrovascular accident (stroke) and transient ischemic attack. The number of participants with CV events confirmed by adjudication is summarized cumulatively at 24 weeks plus 30-day follow up. Serious and all other non-serious adverse events regardless of causality are summarized in the Reported Adverse Events module.

ITT population: All randomized participants who received at least one dose of study drug.

The number of participants with pancreatitis confirmed by adjudication is summarized cumulatively at 24 weeks plus 30-day follow up. A summary of serious and other non-serious adverse events regardless of causality is located in the Reported Adverse Events module.

ITT population: all randomized participants who received at least one dose of study drug.

Participants who received at least one dose of study drug and evaluable calcitonin data at baseline and post-baseline.

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.

ITT Population: all randomized participants who received at least one dose of study drug.

The hypoglycemia rate per 30 days during defined period is calculated by the number of hypoglycemia events within the period/number of days participant at risk within the period*30 days.

ITT population: all randomized participants who received at least one dose of study drug.

Additional Intervention: any additional therapeutic intervention in participants who developed persistent, severe hyperglycemia despite full compliance with the assigned therapeutic regimen, or initiation of an alternative antihyperglycemic medication following study drug discontinuation.

ITT population: all randomized participants who received at least one dose of study drug.

An additional intervention (rescue therapy) was defined as any additional therapeutic intervention in participants who developed persistent, severe hyperglycemia despite full compliance with the assigned therapeutic regimen, or initiation of an alternative antihyperglycemic medication following study drug discontinuation. Participants who had no rescue therapy within specified study period were considered as censored observations at the last available contact date up to specified study period.

ITT population: All randomized participants who received at least one dose of study drug.

Number of participants with treatment emergent (TE) dulaglutide anti-drug antibodies from postbaseline to follow up were summarized. A participant is considered to have TE dulaglutide ADA if the participant has at least one titer that is treatment-emergent relative to baseline, defined as a 4-fold or greater increase in titer from baseline measurement.

ITT population: all randomized participants who received at least one dose of study drug.

A summary of changes in lipase evaluation from baseline to endpoint.

All participants who received at least one dose of study drug and had evaluable lipase data at both baseline and post-baseline. LOCF was used to impute missing postbaseline values. If no data after date of randomization, the endpoint was considered missing.

A summary of changes in amylase evaluation from baseline to endpoint.

Participants who received at least one dose of study drug and had evaluable amylase data at both baseline and post-baseline. LOCF was used to impute missing postbaseline values. If no data after date of randomization, the endpoint was considered missing.
