Study Endpoints

Primary Endpoints

Percent Change from Baseline in Body Weight
Baseline, Week 24
Change From Baseline in Body Weight at Week 48
Baseline, Week 48

Least Square mean was determined by MMRM model for post-baseline measures: Variable is modelled by Gender (Male, Female), Country (Australia, New Zealand, United States of America), Visit, Treatment, and Visit-by-Treatment interaction as fixed effects, and Baseline as a covariate. Variance-Covariance structure= Unstructured. Only participants with non-missing baseline value were included in analysis. No imputation was performed for missing values.

Number of Participants with One or More Treatment Emergent Adverse Events (TEAEs) and Serious Adverse Event(s) (SAEs) Considered by the Investigator to be Related to Study Drug Administration
Baseline to Study Completion (Up to 19 Weeks)

A summary of TEAEs and SAEs regardless of causality, will be reported in the Reported Adverse Events module
