Brief summary
The purpose of this study is to determine the safety, tolerability and pharmacokinetics of ALN-HBV in healthy adult volunteers and patients with chronic hepatitis B virus (HBV) infection. In addition, the study will assess antiviral efficacy of ALN-HBV in patients with HBV.
Detailed description
The study has 3 parts. Part A is a single ascending dose (SAD) study in healthy volunteers. Part B is a single ascending dose study (SAD) in patients with HBV infection. Part C is a multiple ascending dose study (MAD) in patients with HBV infection.
Interventions
Ascending doses of ALN-HBV by subcutaneous (sc) injection
Calculated volume to match active comparator
