Multiple approved therapeutic options exist for
patients with ATTR‑CM and hATTR‑PN
TTR silencers3,4
- Antisense oligonucleotides (ASOs) are short, chemically modified oligonucleotides that reduce the production of TTR protein
- RNA interference (RNAi) therapeutics are double-stranded small interfering RNAs (siRNAs) that reduce the production of TTR protein
TTR stabilizers2,3
- TTR tetramer stabilizers are drug molecules that bind to the TTR protein, preventing the dissociation into monomers

ATTR=transthyretin-mediated amyloidosis; ATTR‑CM=cardiomyopathy of transthyretin-mediated amyloidosis; hATTR=hereditary transthyretin-mediated amyloidosis; hATTR-CM=cardiomyopathy of transthyretin-mediated amyloidosis; hATTR-PN=polyneuropathy of transthyretin-mediated amyloidosis; TTR=transthyretin; wtATTR=wild-type transthyretin-mediated amyloidosis.
