A Study of ALN-HBV in Healthy Adult Volunteers and Non-cirrhotic Patients With Chronic Hepatitis B Virus (HBV) Infection

September 20, 2018 updated by: Alnylam Pharmaceuticals

A Phase 1/2, Randomized, Single-Blind, Placebo-Controlled, Single-Ascending and Multiple-Ascending Dose, Safety, Tolerability, Pharmacokinetics, and Antiviral Efficacy Study of Subcutaneously Administered ALN-HBV in Healthy Adult Subjects and Non-cirrhotic Patients With Chronic Hepatitis B Virus (HBV) Infection

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.

Study Overview

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.
