Overview
11 DESCRIPTION REDEMPLO contains plozasiran (present as plozasiran sodium), a small interfering RNA (siRNA) that degrades apolipoprotein C-III ( apoC-III ) mRNA by RNA interference. Plozasiran contains a covalently linked ligand containing three N-acetylgalactosamine (GalNAc) residues to facilitate delivery to hepatocytes.
Mechanism of Action
12 CLINICAL PHARMACOLOGY 12.1 Mechanism of Action Plozasiran is a siRNA conjugated with GalNAc that degrades the apoC-III mRNA through the RNA interference mechanism resulting in reduced levels of hepatic and serum apoC-III protein. Reduction of apoC- III protein leads to increased clearance of serum triglycerides. 12.2 Pharmacodynamics In Trial 1 [see Clinical Studies ( 14 )] , following the recommended dose of 25 mg administered every 3 months in patients with FCS, REDEMPLO reduced median fasting serum apoC-III protein. The placebo-corrected median percent change in fasting serum apoC-III protein from baseline was -90% at 1 month, -93% at 3 months, -82% at 6 months, -91% at 10 months, and -87% at 12 months.
Indications
- 1 INDICATIONS AND USAGE REDEMPLO is indicated as an adjunct to diet to reduce triglycerides in adults with familial chylomicronemia syndrome (FCS). REDEMPLO is an apolipoprotein C-III ( apoC-III )-directed small interfering ribonucleic acid (siRNA) indicated as an adjunct to diet to reduce triglycerides in adults with familial chylomicronemia syndrome (FCS).
