      Trial Summary

      This randomized study will be conducted in two parts to evaluate the safety, tolerability, pharmacodynamics, and pharmacokinetics of subcutaneous administration of RO7062931. Part 1 will include only healthy participants and Part 2 will include only participants with chronic hepatitis B (CHB). Part 1 is an adaptive, single-ascending dose study with an adaptive dose-escalating schedule to determine the best dose to be evaluated in participants with CHB. Part 2 is an adaptive, parallel multiple-dose study comprised of three sub-parts which will be used to further refine the dose and dosing regimen, and to evaluate the safety and efficacy of RO7062931 when administered with standard-of-care (SoC) therapy.

      A Randomized, Sponsor-Open, Placebo-Controlled Study to Evaluate Safety, Tolerability and Pharmacokinetics and Pharmacodynamics of Subcutaneous Administration of RO7062931 With Single Ascending Doses in Healthy Volunteers and Multiple Doses and Modified Regimens in Virologically Suppressed Patients With Chronic Hepatitis B Virus Infection

      • Women should be of non-childbearing potential. A woman is considered to be of childbearing potential if she is post-menarcheal but has not reached a post-menopausal state and has not undergone surgical sterilization (removal of ovaries and/or uterus).
      • Men must agree to remain abstinent (refrain from heterosexual intercourse) or use contraceptive measures during treatment and up to 105 days after the last dose, and agree to refrain from donating sperm.
      • Non-smoker (nor tobacco containing products) for at least 90 days prior to dosing on Day 1 and agree to remain as non-smoker during the study.

      FOR CHB PARTICIPANTS ONLY - PARTS 2a and 2b:

      • A BMI between 18 to 32 kg/m2 inclusive.

      • On entecavir, tenofovir, adefovir or telbivudine treatment for at least 6 months prior to randomization and will remain on stable treatment during the study.
      • HBV deoxyribonucleic acid (DNA) ≤ 90 IU/mL for at least the preceding 6 months.
      • Screening laboratory values (hematology, chemistry, urinalysis) obtained up to 56 days prior to first study treatment within normal ranges.
      • Liver biopsy, fibroscan® or equivalent test obtained within the past 6 months demonstrating liver disease consistent with chronic HBV infection without evidence of bridging fibrosis or cirrhosis
      • Women should be of non-childbearing potential. A woman is considered to be of childbearing potential if she is post-menarcheal but has not reached a post-menopausal state and has not undergone surgical sterilization (removal of ovaries and/or uterus).
      • Men must agree to remain abstinent (refrain from heterosexual intercourse) or use contraceptive measures during treatment and up to 105 days after the last dose, and agree to refrain from donating sperm.

      FOR CHB PARTICIPANTS ONLY - PART 2c

      • BMI between 18 to 32 kg/m2 inclusive

      • For NUC-suppressed CHB participants: Must have been treated with a single NUC for at least 12 months, and have been on the same NUC therapy for at least 3 months prior to screening; HBV DNA 30 days prior to screening); alanine aminotransferase (ALT) </=2x upper limit of normal (ULN) for >6 months prior to screening and confirmed at screening; total bilirubin within normal range at screening, except for patients with Gilbert's syndrome
      • For treatment-naive and immune-active participants: HBV DNA at screening >/=2x10^4 IU/mL for HBeAg positive participants, or >/=2x10^3 IU/mL for HBeAg negative participants; elevated serum ALT>2 ULN to </=5, 2 values within 6 months, at least one of which is at screening and that are at least 14 days apart; total bilirubin within normal range except for participants with Gilbert's syndrome
      • Screening laboratory values (hematology, chemistry, urinalysis) obtained up to 28 days prior to first study treatment within normal ranges
      • Liver biopsy, fibroscan, or equivalent test obtained within the last 6 months demonstrating liver disease consistent with chronic HBV infection without evidence of bridging fibrosis or cirrhosis
      • Women should be of non-childbearing potential
