Not reported in the public reviews. Reviewers summarise selectively, so this usually means it wasn't discussed publicly, not that it wasn't studied.
Biodistribution & persistence
Highest concentrations in liver, kidney and lung; no retention in melanin-containing tissue
“The highest concentrations were found in liver, kidney and lung and contents of the GI tract. The liver is the main target organ of toxicity in rats (see section 4.2). There was no retention in melanin-containing tissue.”
Hypoglycemia and lactic acidosis deaths at high doses; synergistic toxicity with atorvastatin; rodent PPARα liver effects
“Safety issues identified in animals included unexpected mortalities secondary to hypoglycemia (in rats and monkeys) and lactic acidosis (in rats) as well as synergistic toxicologic interaction between bempedoic acid and atorvastatin in monkeys.”
