The potential to treat HBV
RG6346, formerly referred to as DCR-HBVS, is in development with Roche for the treatment of chronic hepatitis B virus (HBV) infection. Hepatitis B is a serious liver infection. Chronic hepatitis B increases the risk of developing liver failure, liver cancer or cirrhosis — a condition that permanently scars the liver. Current therapies typically provide long-term suppression of the virus, but RG6346 has the potential to provide a functional cure for patients with chronic HBV.
RG6346 leverages the power of RNAi to target the messenger RNA (mRNA) of HBV. We measure the ability for a drug to provide a long-term functional cure of HBV through the clearance of HBV surface antigen (HBsAg) and sustained HBV deoxyribonucleic acid (DNA) suppression in patient plasma or blood.

With its long-acting mechanism, RG6346 may help harness the body’s own immune system to help individuals with chronic HBV infection achieve a functional cure.
RG6346 phase 1 clinical trial
In October 2019, we entered into a research and licensing agreement with Roche to develop RG6346 for the treatment of patients with non-cirrhotic chronic HBV. We are evaluating RG6346 in a Phase 1 clinical trial. This Phase 1 clinical trial is a randomized, placebo-controlled study designed to evaluate the safety and tolerability of RG6346 in healthy volunteers and in patients with non-cirrhotic chronic HBV.
