What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Percentage of Participants Who Experience 1 or More Adverse Event (AE)	An AE was defined as any untoward medical occurrence in a subject which does not necessarily have a causal relationship with the treatment. An AE was any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with use of a medicinal product, whether or not considered related to the medicinal product. The percentage of participants that reported at least 1 AE was summarized.	up to 54 Weeks
Percentage of Participants Who Experience 1 or More Gastrointestinal-related AEs	Gastrointestinal-related AEs included all preferred terms within system organ class of Gastrointestinal Disorders except Chapped Lips and Toothache.	up to 54 weeks
Percentage of Participants Who Experience 1 or More Gallbladder-related AEs	Gallbladder-related AEs included Bile Duct Obstruction, Bile Duct Stone, Bile Duct Stenosis, Biliary Colic, Cholangitis, Cholecystectomy, Cholecystitis, Cholelithiasis, Gallbladder Disorder, Gallbladder Perforation, Hepatic Pain, and Hydrocholecystis.	up to 54 weeks
