“The non-clinical toxicology program supporting belimumab development has been performed exclusively in the cynomolgus monkey (Macaca fascicularis) based on the following reasons:”
Monkey and human BLyS share 96.4% (full-length) and 98% (soluble) identity
“The cynomolgus monkey was considered as the most relevant species in nonclinical studies since the monkey and human BLyS share 96.4% amino acid identity across the full length protein and 98% amino acid identity in the cleaved soluble portion of BLyS”
No surrogate; the clinical antibody was tested in cynomolgus monkeys
