Study Arms:
- Parts 1a and 1b: SAD in Healthy Volunteers (Placebo) (Type: PLACEBO_COMPARATOR): In Part 1a, participants will receive a single oral dose of placebo matching to RO7049389 film coated tablet on Day 1. In Part 1b, minimum 8 participants from Part 1a will be selected and 2 of whom will receive another single dose of placebo matching to RO7049389 on Day 16 after eating the standard United States - Food and Drug Administration (US FDA)-recommended high-fat and high-calorie breakfast.
- Parts 1a and 1b: SAD in Healthy Volunteers (RO7049389) (Type: EXPERIMENTAL): In Part 1a, participants will receive a single oral dose of RO7049389 film coated tablet on Day 1 in dose-escalation cohorts with a starting dose of 150 milligrams (mg). The doses for subsequent cohorts will be defined by an adaptive approach based on the safety and PK data in previously-dosed healthy volunteers. In Part 1b, minimum 8 participants from Part 1a will be selected and 6 of whom will receive another single dose of RO7049389 on Day 16 after eating the standard US FDA-recommended high-fat and high-calorie breakfast.

Participants will also receive a single dose of midazolam solution (100 micrograms \[mcg\]) on Day -1 and Day 14.
- Part 1c: MAD in Healthy Volunteers (RO7049389) (Type: EXPERIMENTAL): Participants will receive RO7049389 film coated tablet from Days 1 to 13 (either QD or BID; dose and regimen will be decided based on the available PK and safety data) and a single dose of RO7049389 film coated tablet in the morning of Day 14. Participants will also receive a single dose of midazolam solution (100 mcg) on Day -1 and Day 14.

- Part 2: POM in Chronic HBV Participants (RO7049389) (Type: EXPERIMENTAL): Participants will receive RO7049389 film coated tablet from Days 1 to 27 (either QD or BID; dose and regimen will be decided based on the available PK and safety data) and a single dose of RO7049389 film coated tablet in the morning of Day 28.
- Part 3: POM in NUC-Suppressed CHB Participants (Cohort A) (Type: EXPERIMENTAL): Participants will receive RO7049389 on top of a NUC for 48 weeks at a dose determined from Part 2. NUC therapy will be administered per local label or guidelines.
- Part 3: POM in Treatment-Naive CHB Participants (Cohort B) (Type: EXPERIMENTAL): Participants will receive RO7049389 for 4 weeks, followed by RO7049389 with an added NUC for 44 weeks. RO7049389 will be administered at a dose determined from Part 2. NUC therapy will be administered per local label or guidelines.
- Part 3: POM in Treatment-Naive CHB Participants (Cohort C) (Type: EXPERIMENTAL): Participants will receive RO7049389 + NUC + Pegylated-Interferon (Peg-IFN) for 48 weeks. RO7049389 will be administered at a dose determined from Part 2. NUC and Peg-IFN therapy will be administered per local label or guidelines.
