Negative in Ames, mouse lymphoma and rat and mouse micronucleus assays
“Vericiguat was not genotoxic in the in vitro microbial mutagenicity (Ames) assay, the in vitro mouse lymphoma assay and the in vivo rat and mouse micronucleus assay.”
“Carcinogenicity was evaluated in 2-year studies conducted in CD1 mice and Wistar rats. Vericiguat did not show a carcinogenic effect in mice dosed up to 150 mg/kg/day (males) or up to 250 mg/kg/day (females).”
Rabbit EFD: cardiac ventricular septal defect and truncus arteriosus at ≥2.5 mg/kg/day (≥4x MRHD exposure)
“An increased incidence of cardiac ventricular septal defect along with truncus arteriosus communis was observed at ≥2.5 mg/kg/day, which is ≥4 times the human exposure at the MRHD.”
Dog telemetry: PR interval effect with heart-rate change, possible QRS effect, no QT/QTc effect
“The cardiovascular safety pharmacology in telemetered dogs indicated an effect on the PR interval concurrent with a change in heart rate, possibly an effect on the QRS complex but no effect on QT/QTc intervals.”
Not genotoxic overall: Ames negative; in vitro chromosome aberration positive without (not with) metabolic activation; rat micronucleus and comet negative
