Pelacarsen  (Synonyms: AKCEA-APO(a)-LRx; ISIS 681257; TQJ230)

Pelacarsen (AKCEA-APO(a)-LRx) is a liver-specific antisense oligonucleotide against apolipoprotein(a) that reduces lipoprotein(a) up to 80% with good tolerability^[1].

Apolipoprotein(a)^[1]

Mice dosed with Pelacarsen at dose levels of 0.3, 1, 3, and 10 mg/kg once weekly for 6 weeks had dose-dependent reductions in target mRNA expression. The model-estimated doses for Pelacarsen that produced 50% of maximum drug-induced inhibitory effect (ED50) for liver apo(a) mRNA and plasma apo(a) protein levels were 0.32 and 0.54 mg/kg/week, respectively.
