Study type
Interventional
Description of intervention(s) / exposure
Treatment: Drugs - RO7062931
Treatment: Drugs - Placebo
Treatment: Drugs - Immune Modulator

Experimental: Part 1: Single-Ascending Dose (SAD) - Healthy volunteers will be enrolled in up to 8 cohorts with doses starting from 0.1 mg/kg and escalating sequentially after review of safety and pharmacokinetic (PK) data.

Experimental: Part 2: Multiple Ascending Dose - Participants with Chronic Hepatitis B will enrolled in Part 2. In Part 2a, participants will receive two monthly injections of either 3 doses equivalent to a multiple of the saturation dose or placebo in a 1:1:1:1 ratio. In Part 2b, a dose selected from Part 2a will be administered to participants randomized into 4 cohorts where they will be dosed weekly (QW) or bi-weekly (Q2W). Each of the cohorts in Part 2b will include participants receiving active drug or placebo in a 3:1 ratio. In Part 2c, NUC-suppressed CHB participants will receive either RO7062931+NUC for up to 24 weeks, or RO7062931+NUC+an immune modulator for up to 48 weeks, at a dose determined from Part 2a and 2b. Part 2c may also enroll treatment-naive immune-active CHB participants.


Treatment: Drugs: 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.

Treatment: Drugs: 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.

Treatment: Drugs: Immune Modulator
Participants in Part 2c will receive an immune modulator subcutaneously QW for up to 48 weeks.

Summary
Brief 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.
