      Trial 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.

      Inclusion Criteria

      Part 1- Healthy Volunteers only:

      • Absence of evidence of any active or chronic disease following a detailed medical and surgical history, a complete physical examination including vital signs, 12-lead Electrocardiogram (ECG), hematology, blood chemistry, serology and urinalysis
      • A Body Mass Index (BMI) between 18 to 30 kilograms per square meter (kg/m^2) inclusive
      • Female participants must be either surgically sterile or post-menopausal for at least one year
      • For men: agreement to remain abstinent or use contraceptive measures, and agreement to refrain from donating sperm

      Part 2- Chronic HBV-infected participants only:

      • A BMI between 18 to 30 kg/m^2 inclusive
      • Chronic Hepatitis B infection, defined as positive test for Hepatitis B surface antigen (HBsAg) for more than 6 months prior to randomization
      • HBV DNA at screening greater than or equal to (>/=) 2 × 10^4 international units per milliliter (IU/mL) for Hepatitis B e antigen (HBeAg) positive participants, or >/=2 × 10^3 IU/mL for HBeAg-negative participants
      • Liver biopsy, fibroscan or equivalent test obtained within the past 6 months demonstrating liver disease consistent with chronic HBV infection with absence of extensive bridging fibrosis and absence of cirrhosis
      • For men: agreement to remain abstinent or use contraceptive measures, and agreement to refrain from donating sperm
      • For women of childbearing potential: agreement to remain abstinent or use non-hormonal contraceptive methods that result in a failure rate of less than (<)1 percent (%) per year during the treatment period and for at least 3 months after the last dose of study drug

      Part 3- Chronic HBV Participants Only:

      • A BMI between 18 to 32 kg/m^2 inclusive
      • Chronic hepatitis B infection, defined as positive test for HBsAg or HBV DNA, or positive HBeAg, for more than 6 months prior to screening
      • For Cohorts only enrolling NUC-suppressed CHB participants (e.g. POM Cohort A), participants must have been treated with a single NUC (entecavir, tenofovir alafenamide, or tenofovir disoproxil fumarate) for at least 12 months. Participants must be on the same NUC therapy for at least 3 months prior to screening
      • For Cohorts only enrolling anti-HBV treatment-naive and immune-active participants (e.g. POM Cohort B and Cohort C), previous anti-HBV treatments <30 days in total, and did not receive any anti-HBV treatments within 3 months prior to the first study dose
      • Liver biopsy, fibroscan, or equivalent test obtained within the past 6 months demonstrating liver disease consistent with chronic HBV infection with absence of extensive bridging fibrosis and absence of cirrhosis
      • For men: agreement to remain abstinent or use contraceptive measures, and agree to refrain from donating sperm
      • For women of childbearing potential: agreement to remain abstinent or to use two approved contraceptive methods during the study and for at least 6 months after the last dose of study drug
