Negative in Ames, human lymphocyte chromosomal aberration and rat bone marrow micronucleus assays
“Gedatolisib was not mutagenic in an in vitro bacterial reverse mutation (Ames) assay and not clastogenic in a human lymphocyte chromosomal aberration assay. Gedatolisib was not genotoxic in the in vivo rat bone marrow micronucleus assay.”

Reproductive & developmental
Not conducted: no fertility or EFD studies (advanced cancer; given with drugs known to cause EFD toxicity)
“Fertility and early embryonic development studies are not required as gedatolisib is indicated for the treatment of patients with advanced cancer. In addition, embryo-fetal development studies were not conducted as gedatolisib will be administered in combination with palbociclib and fulvestrant, both of which are known to cause embryo-fetal developmental toxicities.”

Safety pharmacology
Dog CV study: 5 mg/kg raised heart rate (24%) and blood pressure (6%); no QTc or other ECG effects
“In a single dose safety pharmacology study, a 5 mg/kg IV dose of gedatolisib administered to dogs increased heart rate (24%) and arterial blood pressure (6%) compared to control 12- to 33-hours post-dose, without an effect on QTc prolongation or other ECG parameters.”

Not genotoxic overall: Ames negative; in vitro chromosome aberration positive without (not with) metabolic activation; rat micronucleus and comet negative
