Efficacy evidence
Human mutant TTR (I84S) transgenic mice: hepatic hTTR mRNA and plasma TTR reduction
“The pharmacological in vivo activity of eplontersen was investigated in comparison to inotersen in transgenic mice overexpressing a mutant human TTR variant known to cause familial amyloid polyneuropathy in humans (hTTR I84S; Benson et al., 2006).”
Why that model
Sequence fully complementary to human and monkey TTR mRNA; 8 mismatches in mice and rats preclude activity
“The target sequence of eplontersen and inotersen is 100 % complementary to human and Cynomolgus monkey TTR mRNA, whereas 8 mismatches in mice and rats preclude effective hybridisation and, hence, pharmacological activity in these animals.”
Reviewer's view of the efficacy data
EMA: transgenic mice lack disease symptoms, so only hTTR suppression could be evaluated
“As these transgenic mice do not develop the cardiac, neuronal or renal symptoms of the human disease, only the suppression of hTTR mRNA translation could be evaluated.”
