Efficacy evidence
NASH in db/db mice on MCD diet and chemically induced (CCl4) liver fibrosis in rats; no PBC model
“Due to the absence of an animal model that adequately mimics the pathophysiology of human primary biliary cholangitis (PBC), the pharmacological effects of elafibranor have been studied in rodent models of NASH (characterized by liver inflammation and fibrosis, relevant to PBC) and chemically induced liver fibrosis.”

Why that model
No animal model adequately mimics human PBC; NASH and fibrosis models used instead
“Due to the absence of an animal model that adequately mimics the pathophysiology of human primary biliary cholangitis (PBC), the pharmacological effects of elafibranor have been studied in rodent models of NASH (characterized by liver inflammation and fibrosis, relevant to PBC) and chemically induced liver fibrosis.”

Reviewer's view of the efficacy data
EMA: effective on steatosis in NASH and CCl4 models, but may not translate to PBC benefit given distinct pathophysiology
“Nevertheless, although elafibranor is effective in reducing steatosis in the NASH and CCL4 animal models, it may not necessarily translate to a therapeutic benefit in PBC in human, as the underlying mechanisms and pathophysiology of PBC are distinct from those of steatosis-related liver diseases.”
