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.

Conditions

Interventions

DRUG

RO7062931

Administered subcutaneously in Parts 1 and 2. Part 1 will be administered in single-ascending doses after 0.1 mg/kg starting dose. Subsequent doses of 0.3, 1, 2 and 4 mg/kg may be administered based upon tolerability. In Part 2a, participants will receive two monthly doses of either 0.4, 0.8, 1.2 times the saturation dose or placebo. In Part 2b, a dose selected from Part 2a will be administered to participants randomized into 4 cohorts QW or Q2W. In Part 2c, participants will receive RO7062831 QW on top of another therapy for up to 24 or 48 weeks.

DRUG

Placebo

Part 1 cohorts: active drug vs placebo 4:1. Part 2a 4 parallel cohorts of 3 active drug doses and placebo in 1:1:1:1. Part 2b active drug vs placebo in 3:1 in 2 parallel cohorts.

DRUG

Immune Modulator

Participants in Part 2c will receive an immune modulator subcutaneously QW for up to 48 weeks.
