Negative in Ames, mouse lymphoma and in vivo mouse micronucleus assays
“Genetic toxicology studies showed that seladelpar was negative in the in vitro bacterial reverse mutation (Ames) assay, the in vitro mouse lymphoma assay, and the in vivo mouse micronucleus test.”
2-year mouse: hepatocellular adenoma or carcinoma at 6x (males) and 140x (females) human AUC
“In a 2-year study in mice, oral administration of seladelpar produced hepatocellular adenoma or carcinoma at 6 times the human exposure (AUC at the recommended dose) in males and at 140 times the human exposure in females.”
No effects on male or female rat fertility (up to 271x and 115x human AUC)
“Seladelpar had no effects on fertility or reproductive function in male rats at up to 271 times the human exposure (AUC) at the recommended dose or in female rats at up to 115 times the human exposure.”
No significant cardiovascular, respiratory or CNS concerns
“Overall, the safety pharmacology data indicates that there are no safety issues of significant concern for cardiovascular function, respiratory function, or the central nervous system.”
Not genotoxic overall: Ames negative; in vitro chromosome aberration positive without (not with) metabolic activation; rat micronucleus and comet negative
