Study of Safety and Tolerability of DCR HBVS

Phase 1
Completed
Conditions
Hepatitis B, Chronic
Interventions
Drug: Placebo for DCR-HBVS
Registration Number
NCT03772249
Lead Sponsor
Dicerna Pharmaceuticals, Inc., a Novo Nordisk company
Brief Summary

DCR-HBVS will be evaluated for safety and efficacy in healthy volunteers and chronic hepatitis B patients.

Detailed Description

DCR HBVS is being developed for the treatment of chronic hepatitis B (CHB) in adults. The study will be conducted in 3 parts, a single ascending-dose (SAD) phase in normal healthy volunteers (Group A), a single-dose (SD) phase in patients with CHB (Group B), and a multiple ascending-dose (MAD) phase in patients with CHB (Group 1c-3c). Cohort 4c is a single ascending dose with a possible duration of up to 48 weeks. Cohort 5c is a multiple dose cohort with a possible duration of up to 72 weeks.
