Interventions

DCR-HBVS is a synthetic ribonucleic acid interference (RNAi) drug that consists of a double-stranded oligonucleotide conjugated to N-acetyl-D-galactosamine (GalNAc) ligands. DCR-HBVS is a sterile solution of the siRNA (DCR-S219) at a concentration of 195 mg/mL in water for injection (WFI).

Masking Details
This is a double-blind study in which the study site team, the Sponsor, and the participants will be blinded to treatment assignment. The unblinded pharmacist will cover each syringe, prior to transport to the bedside, to ensure blinding. The drug will be injected by an unblinded nurse or physician who is not part of the study team. Participants will be centrally assigned to randomized study intervention using an Interactive Voice/Web Response System (IVRS/IWRS). Cohorts 4c and 5c will be open label.
Purpose
TREATMENT
Intervention Model
SEQUENTIAL
Model Details: Progression from the SAD phase to the first cohort in the MAD phase is contingent upon the Safety Review Committee (SRC) review of a minimum of 14 days post-dose safety and tolerability data from all NHV in at least the first 2 SAD cohorts. The SRC will select one (or more) well-tolerated dose(s) from the SAD phase for administration in the SD and MAD phases. Group B at 3 mg/kg will start in parallel with Group C at the 3 mg/kg dose level. In all study phases, dosing will be staggered with the use of sentinel participants to allow time for the assessment of safety before additional subjects are exposed to study drug. The fixed dosing regimen for Cohorts 4c and 5c was determined following SRC review and assessment of all data up to Cohort 3c. No sentinel dosing will occur in Cohorts 4c and 5c.
