Brief Summary

This sponsor-open, investigator- and participant-blinded, multi-center study will assess the safety, tolerability, pharmacokinetics and pharmacodynamics of RO7020531 in healthy participants and in participants with chronic hepatitis B. Part I will be conducted in two portions: Single Ascending Dose (SAD) and Multiple Ascending Dose (MAD) which will include only healthy volunteers. Part II will commence after completion of the MAD portion of Part I and will include only Chronic Hepatitis B (CHB) participants.

Conditions

Hepatitis B, Chronic

Outcome Measures

Primary Outcomes (12)

• Part 1: Percentage of SAD Participants With Adverse Events (AEs)

  An AE is any untoward medical occurrence in a clinical investigation healthy volunteer (HV)/participant administered a pharmaceutical product, regardless of causal attribution. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product, any new disease or exacerbation of an existing disease (a worsening in the character, frequency, or severity of a known condition and recurrence of an intermittent medical condition (e.g., headache) not present at baseline.

  From randomization up to Day 29

• Part 1: Percentage of MAD Participants With AEs

  An AE is any untoward medical occurrence in a clinical investigation healthy volunteer (HV)/participant administered a pharmaceutical product, regardless of causal attribution. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product, any new disease or exacerbation of an existing disease (a worsening in the character, frequency, or severity of a known condition and recurrence of an intermittent medical condition (e.g., headache) not present at baseline.

  From randomization up to Day 41

• Part 2: Percentage of Chronic Hepatitis B Participants With AEs

  An AE is any untoward medical occurrence in a clinical investigation participant administered a pharmaceutical product, regardless of causal attribution. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product, any new disease or exacerbation of an existing disease (a worsening in the character, frequency, or severity of a known condition and recurrence of an intermittent medical condition (e.g., headache) not present at baseline.
