Negative in Ames, in vitro chromosomal aberration and mouse bone marrow micronucleus assays
“Cipepofol was not genotoxic in a standard battery of genotoxicity assays, testing negative in an in vitro Ames assay, in the in vitro chromosomal aberration assay, and in the in vivo bone marrow micronucleus test in mice.”

Rat FEED: increased post-implantation loss from resorptions, likely related to maternal hypoxia secondary to anesthesia
“It appears that the significantly increased post-implantation loss was mainly driven by increased resorption. Similar, but not significant and not dose-dependent, effects were observed in the FEED study in rats with every other day IV dosing. The reproductive effects observed in the FEED studies are likely related to maternal hypoxia secondary to anesthesia.”

Dog CV study: transient hypotension and QTcF increase during anesthesia
“Temporary cardiovascular (CV) effects during anesthesia, including reduced blood pressure and ECG changes such as an increase in QTcF, were observed in the cardiovascular safety pharmacology study and a single-dose toxicology study in dogs.”
