- The safety of ALN-PCSSC evaluated by the proportion of subjects experiencing adverse events (AEs), serious adverse events (SAEs), and AEs leading to study drug discontinuation [ Time Frame: Part 1 (SAD phase): up to 180 days post dose; Part 2 (MD) phase: up to 180 days post final dose ]
- The pharmacokinetics (PK) of ALN-PCSSC (Cmax, tmax, AUC, t1/2) [ Time Frame: Part 1 (SAD) phase: predose, 0.5,1,2,4,6,8,12,24,48,72,96 hours; 7, 14, 21, 28, 42, 56 days post-dose; Part 2 (MD) phase: predose, 0.5,1,2,4,6,8,12,24,48,72,96 hours; 7, 14, 21, 28, 29, 35, 42, 56, 84 days post-dose ]
- The effect of ALN-PCSSC on serum levels of LDL-C [ Time Frame: Through the sooner of final follow up visit or 180 days post final dose ]
- The effect of ALN-PCSSC on plasma levels of PCSK9 [ Time Frame: Through the sooner of final follow up visit or 180 days post final dose ]
