Why that species
Comparison of in vivo metabolites supported cynomolgus monkey as the non-rodent species
“From the comparison of metabolites formed in vivo in Cynomolgus monkeys and in humans, the applicant did conclude that Cynomolgus monkeys could be used as the non-rodent species for toxicity studies.”
“A two-year carcinogenicity study of pitolisant was conducted in rats and a 6-month carcinogenicity study was conducted in tgRasH2 mice. The executive carcinogenicity assessment committee concluded that these studies were adequate and that there were no drug-related neoplasms in either study.”
