vutrisiran · TTR (siRNA)
Efficacy evidence
hTTR V30M transgenic mice and cynomolgus monkeys: up to >=98% serum TTR reduction
“Subcutaneous (SC) administration of vutrisiran to hTTR V30M transgenic mice and cynomolgus monkeys resulted in maximal reductions of ≥98% in serum TTR protein.”
Why that model
TTR binding region identical in human and monkey but not conserved in mice, rats, rabbits; in vivo work limited to monkeys and V30M transgenic mice
“As the binding region of vutrisiran in the TTR mRNA is identical between humans and monkeys, but is not conserved in mice, rats and rabbits, non-clinical in vivo “proof-of-concept” investigations were restricted to monkeys and transgenic mice expressing the most prevalent human valine to methionine variant of TTR at amino acid 30 (V30M).”
Reviewer's view of the efficacy data
EMA: vutrisiran effectively silenced TTR in monkeys and human transgenic mice; profile consistent with GalNAc-siRNA class
“Vutrisiran effectively silenced TTR transcript levels in monkeys and human transgenic mice. The general pharmacokinetic and toxicological properties of vutrisiran coincide with earlier experience gained with other members of this class of GalNAc-conjugated siRNAs.”
