Study 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.

PrimaryPart 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.

PrimaryPart 1: Percentage of SAD Participants With Abnormalities in Vital Signs

Vital signs include blood pressure, pulse rate, respiratory rate and body temperature. Blood pressure, respiratory rate and pulse rate were obtained after the participant had been in a supine or sitting position for at least 5 minutes. Blood pressure measurement were performed in triplicate (can be as short as 20 second to 1 minute interval between measurements).
