Genotoxicity
Negative in Ames, in vitro chromosome aberration and rat bone marrow micronucleus assays
“BHV-3000 was negative in Ames, chromosomal aberration, and rat bone marrow micronucleus assays.”
Carcinogenicity
26-week Tg.rasH2 mouse and 2-year rat: no drug-induced tumors
“Based on a review by the CDER Division of Biometrics, BHV-3000 did not induce tumor formation in the 26-week and 2-year carcinogenicity studies in TgRasH2 mice (0, 30, 100 300 mg/kg) and SD rats (0, 5, 15, 45 mg/kg), respectively.”

Reproductive & developmental
Rat fertility: uterine atrophy >25 mg/kg, reduced conception at 150 mg/kg; no embryofetal toxicity in rat or rabbit
“Two fertility studies in SD rat indicated uterine atrophy at doses greater than 25 mg/kg, and decreased conception and increased pre-implantation loss at 150 mg/kg. There was no embryofetal toxicity in rat or rabbit.”
Safety pharmacology
No CNS, cardiovascular or respiratory effects; hERG and sodium channel IC50 >30 µM
“There were no effects of BHV-3000 on CNS, cardiovascular, or respiratory safety pharmacology endpoints, and the IC50 for hERG or sodium ion channels was estimated to be in excess of 30 uM.”
Genotox: Ames
Negative
“Rimegepant was negative in a standard battery of genetic toxicology (Ames, in vitro chromosomal aberration in Chinese hamster ovary cells, in vivo male Sprague-Dawley rat micronucleus) assays.”
Genotox: in vitro mammalian
Chromosomal aberration in CHO cells: negative
“Rimegepant was negative in a standard battery of genetic toxicology (Ames, in vitro chromosomal aberration in Chinese hamster ovary cells, in vivo male Sprague-Dawley rat micronucleus) assays.”
Genotox: in vivo
Rat micronucleus: negative
“Rimegepant was negative in a standard battery of genetic toxicology (Ames, in vitro chromosomal aberration in Chinese hamster ovary cells, in vivo male Sprague-Dawley rat micronucleus) assays.”
Carcinogenicity model
Short-term Tg.rasH2 mouse and 2-year SD rat: not carcinogenic
“Rimegepant was not carcinogenic in a short-term study in hemizygous Tg.rasH2 mice and a 2 year lifespan study in Crl:CD(SD) rats.”
Carcinogenicity timing
26-week Tg rasH2 mouse and 2-year rat completed before the marketing application
“Based on a review by the CDER Division of Biometrics, BHV-3000 did not induce tumor formation in the 26-week and 2-year carcinogenicity studies”
hERG / QT
hERG and sodium channel IC50 >30 µM; no cardiovascular safety pharmacology effects
“There were no effects of BHV-3000 on CNS, cardiovascular, or respiratory safety pharmacology endpoints, and the IC50 for hERG or sodium ion channels was estimated to be in excess of 30 uM.”
