Timeframe: Baseline to Week 12

Population: Mean change from baseline in Enhanced Liver Fibrosis Score was assessed in the Full Analysis Set.

Enhanced Liver Fibrosis (ELF) score is a non-invasive blood test derived from the measurement of hyaluronic acid (HA), amino terminal propeptide of type III procollagen (PIIINP), and tissue inhibitor of metalloprotease 1 (TIMP1) using a proprietary algorithm (Siemens). ELF score is a laboratory test, is unitless, and is used as a continuous variable. The minimal ELF score is zero, the maximal ELF score is unknown. The higher the ELF score, the worse the disease outcome. ELF is a score on a scale of severity assessment against biopsy-proven fibrosis. A score of \<7.7 is none to mild, \> 7.7-9.8 is moderate, \> 9.8 is severe.

SECONDARY outcome

Timeframe: Baseline to Week 12

Population: Severity of inflammatory bowel disease-associated intestinal symptoms were assessed in the Full Analysis Set.

Severity of inflammatory bowel disease (IBD)-associated symptoms and acute cholangitis are summarized with number and percentage. The partial Mayo IBD scale assesses stool frequency, rectal bleeding, and there is a Physician's global assessment. Each section is summed and remission is defined as a total score of 0-1, mild disease 2-4, moderate disease 5-6, and severe disease 7-9. Higher total scores indicate more severe disease. The number of participants are being presented based on the severity of their IBD symptoms.
