Rivfloza: which tox species, and why?
nedosiran · LDHA (siRNA)
Species
Cynomolgus monkey (relevant) plus mouse (nedosiran inactive; off-target assessment)
“Nedosiran is inactive in the mouse because the LDHA mRNA sequence is different from humans, and hence, the toxicology of nedosiran was studied in the mouse to assess off-target hybridization effects.”
Why that species
LDHA mRNA target sequence 100% homologous in monkey; not conserved in mouse
“The monkey is considered a pharmacologically relevant model because the LDHA mRNA target sequence has 100% homology with humans.”
Surrogate molecule
Yes: mouse-active analog DCR-m355 used in pharmacology and mouse reproductive studies
“The effects of knockdown of LDHA mRNA were also assessed in genetically or chemically induced mouse models of PH using the pharmacologically active mouse-specific analog DCR-m355.”
