Primary Outcome Measures:
- The safety of ALN-AS1 evaluated by the proportion of subjects experiencing adverse events (AEs), serious adverse events (SAEs), and AEs leading to study drug discontinuation [ Time Frame: Part A (SAD phase): through day 42; Part B (MAD) phase: through Day 70; Part C (MD) phase: through Day 168 ]
Secondary Outcome Measures:
- Profile of Pharmacokinetics (PK) of ALN-AS1 [ Time Frame: Part A (SAD) phase: predose - 42 days post-dose; Part B (MAD) phase: predose - 70 days post-dose; Part C (MD) phase: predose - 168 days post-dose ]Cmax, tmax, AUC, t1/2
- The change in delta-aminolevulinic acid (ALA) from baseline [ Time Frame: Part A (SAD) phase: screening - 42 days post-dose; Part B (MAD) phase: screening - 70 days post-dose; Part C (MD) phase: screening - 168 days post-dose ]
- The change in Porphobilinogen (PBG) from baseline [ Time Frame: Part A (SAD) phase: screening - 42 days post-dose; Part B (MAD) phase: screening - 70 days post-dose; Part C (MD) phase: screening - 168 days post-dose ]
