Negative in Ames, in vitro chromosomal aberration and in vivo rat bone marrow micronucleus assays
“In genetic toxicology assessments, ubrogepant was negative in OECD-compliant Ames, in vitro chromosomal aberration, and in vivo rat bone marrow micronucleus assays.”

Carcinogenicity
104-week CD-1 mouse and Wistar rat oral studies: no drug-related neoplasms
“In adequately designed and conducted 104-week oral carcinogenicity studies in CD-1 mouse (0, 5, 15, and 50 mg/kg/day) and Wistar rat (males: 0, 10, 30, and 100 mg/kg/day; females: 0, 10, 30, and 150 mg/kg/day), ubrogepant was negative for drug-related neoplasms.”

Reproductive & developmental
Rabbit EFD: embryofetal mortality; rat PPND: lower offspring body weight; both at maternally toxic doses
“In animal studies, adverse effects on embryofetal development were observed following administration of ubrogepant during pregnancy (increased embryofetal mortality in rabbits) or during pregnancy and lactation (decreased body weight in offspring in rats) at doses greater than those used clinically and which were associated with maternal toxicity”
hERG negative; no respiratory (75 mg/kg) or cardiovascular (300 mg/kg) effects in telemetered rhesus monkeys
“Ubrogepant was negative in an in vitro hERG assay. There were no effects on respiratory or cardiovascular parameters at oral doses up to 75 mg/kg or 300 mg/kg, respectively, in telemetered Rhesus monkeys.”

Genotox: Ames
Negative
“In genetic toxicology assessments, ubrogepant was negative in OECD-compliant Ames, in vitro chromosomal aberration, and in vivo rat bone marrow micronucleus assays.”

Genotox: in vitro mammalian
Chromosomal aberration in Chinese hamster ovary cells: negative
“Ubrogepant was negative in in vitro (Ames, chromosomal aberration test in Chinese Hamster Ovary cells) and in vivo (rat bone marrow micronucleus) assays.”
“Ubrogepant was negative in in vitro (Ames, chromosomal aberration test in Chinese Hamster Ovary cells) and in vivo (rat bone marrow micronucleus) assays.”
104-week oral CD-1 mouse and Wistar rat; mouse study judged inadequate (AUC margin <25-fold MRHD)
“Ubrogepant was negative in 104-week mouse (up to 50 mg/kg) and rat (up to 100(M) and 150(F)) carcinogenicity studies, according to the FDA statistical analysis. However, the mouse study was not adequate because the safety margin based on AUC at the highest dose tested was less than 25-fold the MRHD.”

Carcinogenicity timing
104-week CD-1 mouse and Wistar rat studies completed before the marketing application
“In adequately designed and conducted 104-week oral carcinogenicity studies in CD-1 mouse (0, 5, 15, and 50 mg/kg/day) and Wistar rat (males: 0, 10, 30, and 100 mg/kg/day; females: 0, 10, 30, and 150 mg/kg/day), ubrogepant was negative for drug-related neoplasms.”

hERG / QT
Negative in hERG assay; no cardiovascular effects up to 300 mg/kg in telemetered rhesus monkeys
“Ubrogepant was negative in an in vitro hERG assay. There were no effects on respiratory or cardiovascular parameters at oral doses up to 75 mg/kg or 300 mg/kg, respectively, in telemetered Rhesus monkeys.”

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