Why that species
Not stated in public reviews
The reviews list the species but not why. For small molecules, ICH M3(R2) expects one rodent and one non-rodent species, chosen with in vitro metabolism, protein binding and exposure data compared with human.
“In vitro metabolic and plasma protein binding data for animals and humans and systemic exposure data (ICH S3A, Ref. 7) in the species used for repeated-dose toxicity studies generally should be evaluated before initiating human clinical trials.”

“The general toxicity of orally administered ubrogepant was assessed in CD-1 mouse (3-month), Wistar rat (7- and 14-day, 1-, 3-, and 6-month), and rhesus monkey (3- and 9-month) GLP-compliant studies.”

Species: DART
Wistar rat (fertility, EFD, pre/postnatal) and New Zealand White rabbit (EFD)
“A standard battery of reproductive and development toxicology studies was conducted for ubrogepant: fertility and early embryonic development (0, 20, 80, and 160 mg/kg), embryofetal development (0, 1.5, 5. 25, and 125 mg/kg), and pre- and postnatal development (0, 25, 60, and 160 mg/kg) in Wistar rat, and an embryofetal development in New Zealand White rabbit”

Species: carcinogenicity
CD-1 mouse and Wistar rat (104-week oral)
“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.”

Surrogate used in
No surrogate used; ubrogepant tested directly in mouse, rat and rhesus monkey
“The general toxicity of orally administered ubrogepant was assessed in CD-1 mouse (3-month), Wistar rat (7- and 14-day, 1-, 3-, and 6-month), and rhesus monkey (3- and 9-month) GLP-compliant studies.”
