Basic Information

• Recruitment Status: COMPLETED

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.

Conditions

Chronic Hepatitis B

Study Design

• Allocation Method: RANDOMIZED
• Intervention Model: PARALLEL
• Primary Study Purpose: BASIC_SCIENCE
• Blinding Strategy: DOUBLE

Study Groups

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.

Group Type: EXPERIMENTAL

RO7062931

Intervention Type: DRUG

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.

Placebo

Intervention Type: DRUG

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.

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.

Group Type: EXPERIMENTAL

RO7062931

Intervention Type: DRUG

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.
