Medication adherence to obeticholic acid: a real-world experience using medication event monitoring systems.

Objective: We designed a clinical study to analyze patterns of adherence to  obeticholic acid, factors influencing the adherence and potential correlation with  treatment efficacy by using MEMS® cap in practice daily. Method: A multicenter prospective observational study of patients with primary  biliary cholangitis. Adherence will be measured by MEMS® cap, pill count, and  patient-reported outcomes during 3 months.
