Study Endpoints

Primary Endpoints

Parts 1, 2, 3, and 4: Percentage of Participants With Adverse Events (AEs) and Serious Adverse Events (SAEs) With Severity of AEs Measured According to National Cancer Institute Common Terminology Criteria for Adverse Events Version 5 (NCI CTCAE V5)
Day 1 to Day 169 for Part 1 and Part 2; Day 1 to Day 197 for Part 3; Day 1 to Day 253 for Part 4
Parts 1, 2, 3, and 4: Change From Baseline in Suicide Risk as Assessed Using the Columbia-Suicide Severity Rating Scale (C-SSRS)
Day 1 to Day 169 for Part 1 and Part 2; Day 1 to Day 197 for Part 3; Day 1 to Day 253 for Part 4

The C-SSRS is an interview-based instrument used to assess baseline incidence of suicidal ideation (SI) and behavior. The assessment includes "yes" or "no" responses for 5 questions, each related to SI (wish to be dead, non-specific active suicidal thoughts, active SI with any methods, active SI with some intent, active SI with specific plan) and suicidal behavior (preparatory acts or behavior, aborted attempt, interrupted attempt, actual attempt, suicide). Numeric ratings are provided for severity of ideation (if present), from 0 to 5. A score of 0 is assigned if no suicide risk is present. A score of 1 or higher indicates SI or behavior, with 5 being the most severe.

Parts 2 and 3: Percentage of Participants With Local Pain at the Site of Injection Assessed Using the Visual Analog Scale (VAS)
Day 1, 2, 5, 8 for Part 2; Day 1, 2, 5, 8, 15, 22, 29, 36 for Part 3

VAS is a 100 millimetre (mm) horizontal visual analog scale with values 0 to 100 mm to indicate pain. The following cutpoints on the VAS will be considered in the interpretation of the pain data: no pain (0-4 mm), mild pain (5-44 mm), moderate pain (45-74 mm), and severe pain (75-100 mm). A higher score indicates greater pain intensity.

Parts 2 and 3: Percentage of Participants With Local Injection-site Reaction Using Local Injection-site Symptom Assessment (LISSA)
Day 1,2, 5, 8 for Part 2; Day 1, 2, 5, 8, 15, 22, 29, 36 for Part 3

LISSA form will be used to assess the participant's injection site for the following categories of reactions: Burning, Itching, Bruising, Erythema (redness), Hive formation, Induration, Swelling, Ecchymosis, Sensitivity, Papules, Stinging, Blister, Cold sensation, and Other. These reactions will be described using the following scale: Unable to assess, less than a dime (\<18 mm/\<0.7 inches), a dime (18 mm/0.7 inches), a nickel (21 mm/0.8 inches), a quarter (24 mm/1 inch), a half dollar (31 mm/1.2 inches), larger than a half dollar (\>31 mm/\>1.2 inches). A higher score indicates high injection site reactions.

Part 4: Percentage of Participants With Local Injection-site Reactions
Day 1 to Day 253

Secondary Endpoints

Parts 1, 2 and 3 (Week 1 and Week 4): Time to Maximum Observed Concentration (Tmax) of RO7121932
Day 1 to Day 169 for Part 1 and Part 2; Days 1, 2, 5 and, 22 for Part 3
Parts 1, 2 and 3 (Week 1 and Week 4): Maximum Observed Serum Concentration (Cmax) of RO7121932
Day 1 to Day 169 for Part 1 and Part 2; Days 1, 2, 5 and, 22 for Part 3
Parts 1, 2 and 3 (Week 1 and Week 4): Area Under the Serum Concentration-time Curve From Time 0 to 168 Hours (h) (AUC0-168h) Postdose
Day 1 (predose) to Day 8 (168 hours post-dose) for Parts 1, 2, and 3 (Week 1) and Day 22 (predose) to Day 29 (168 hours post-dose) for Part 3 (Week 4)

Treatment Arms

ArmTypeDescription
Part 1: Single Ascending Dose (SAD) IV: RO7121932- Dose Escalation Cohorts 1 to 7EXPERIMENTALParticipants will receive a single IV dose of RO7121932 on treatment Day 1. The planned starting dose of RO7121932 is 7 milligrams (mg) and will be escalated up to 2000 mg. The maximum dose will not exceed 4000 mg. Doses may be repeated, adjusted downwards, or intermediate doses may be investigated based on emerging data.
Part 2: SAD SC: RO7121932- Dose Escalation Cohorts 1 to 2EXPERIMENTALParticipants will receive a single SC dose of RO7121932 on treatment Day 1. The planned starting dose of RO7121932 is 70 mg and will be escalated up to 200 mg. Doses may be repeated, adjusted downwards, or intermediate doses may be investigated based on emerging data.
Part 3: Multiple Ascending Dose (MAD) SC: RO7121932- Dose Escalation Cohorts 1 to 3EXPERIMENTALParticipants will receive multiple SC doses of RO7121932, once weekly on treatment Day 1 through Day 22. The planned starting dose of RO7121932 is 70 mg and will be escalated up to 700 mg. Doses may be repeated, adjusted downwards, or intermediate doses may be investigated based on emerging data.
Part 4: Long-term Safety: RO7121932- Dose Escalation Cohorts 1 to 2EXPERIMENTALParticipants will receive a single IV dose of RO7121932 on treatment Day 1 followed by multiple SC maintenance doses of RO7121932. Doses may be repeated, adjusted downwards, or intermediate doses may be investigated based on emerging data.
