February 6, 2024 updated by: Hoffmann-La Roche

A Phase I, Sponsor-Open, Investigator-Blinded, Subject-Blinded, Multi-Center, Placebo-Controlled Study to Evaluate Safety, Tolerability, Pharmacokinetics and Pharmacodynamics of Oral Administration of RO7020531: (1). Single and Multiple Ascending Doses in Healthy Male and Female Subjects; (2). 6-week Treatment of Patients With Chronic Hepatitis B Virus Infection

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.

Part 2: Plasma Concentrations of Tenofovir, Tenofovir Alafenamide, Entecavir, Adefovir and Telbivudine
Time Frame: Pre-dose and 2-4 hours post-dose on Day 1, Day 21 and Day 41
Adefovir was not administered to any participants in the study. Hence, no data could be collected for plasma concentration of adefovir. As participants in each cohort received different NUCs the data for Cohorts 1, 2 and 3 have been reported separately.
