Leqvio: which tox species, and why?
inclisiran · PCSK9 (siRNA)
Species
Rat and cynomolgus monkey (both pharmacologically active); rabbit for EFD
“The drug was pharmacologically active in both rats and NHPs, and therefore these assessments represent characterization of both on-target and off-target effects.”
Why that species
Complete homology to human/cynomolgus PCSK9; partial homology (seed region match) gives partial activity in rodents and rabbit
“The applicant states that the nucleotide sequence of inclisiran exhibits complete homology to the analogous sequences in the human and Cynomolgus monkey PCSK9 genes and partial homology to the rat and mouse PCSK9 gene sequences.”
Surrogate molecule
No surrogate; clinical siRNA used (human PCSK9 transgenic mice for pharmacology only)
“Sequence homology was sufficient to result in pharmacologic activity (LDL-C decreases) of inclisiran in all three species.”
