Conditions
Hepatitis B, Chronic
Interventions
Drug: RO7049389
Drug: Midazolam
Other: Placebo
Registration Number
NCT02952924
Lead Sponsor
Hoffmann-La Roche
Brief Summary

This study is a multicenter, three-part study. Parts 1 and 2 are randomized, investigator- and participant-blinded, placebo-control, single-ascending dose (SAD) and multiple-ascending dose (MAD) study to evaluate the safety, tolerability, pharmacokinetics (PK) and pharmacodynamics (PD) of RO7049389 following oral administration in healthy volunteers and chronic HBV infected participants. Part 3 is a non-randomized, non-controlled, open-label part to assess the efficacy and safety of RO7049389 when administered in combination with standard-of-care therapies for up to 48 weeks in nucleos(t)ide (NUC)-suppressed and treatment-naive chronic hepatitis B (CHB) participants.
