Outcome Measures
Primary Outcomes (4)
Parts 1, 2, and 3: 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
Parts 1, 2, and 3: Change From Baseline in Suicide Risk as Assessed Using the Columbia-Suicide Severity Rating Scale (C-SSRS)
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.
Day 1 to Day 169 for Part 1 and Part 2; Day 1 to Day 197 for Part 3
Parts 2 and 3: Percentage of Participants With Local Pain at the Site of Injection Assessed Using the Visual Analog Scale (VAS)
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.
Day 1, 2, 5, 8 for Part 2; Day 1, 2, 5, 8, 15, 22, 29, 36 for Part 3
Parts 2 and 3: Percentage of Participants With Local Injection-site Reaction Using Local Injection-site Symptom Assessment (LISSA)
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.
