Study Endpoints
Primary Endpoints
Percentage of Evaluable Participants That Prefer SC Route of Administration Using the Patient Experience and Preference Questionnaire (PEPQ) (Question 7) After Cycle 4 Day 1 Dose
Cycle 4 Day 1 (each cycle consist of 4 weeks)

PEPQ included 7 items 1. Pain or Discomfort (rated on 1 to 10 scale), 2. Length of time related to administration 3. Length of time related to administration impact amount of time to speak to doctor or nurse about illness or concern 4. Length of time for administration impact time to interact or socialize with other individuals 5. Convenience 6. Satisfaction 7. Choice of which route of administration would be preferred. 95% CI exact confidence interval was reported.

Progression Free Survival (PFS)
From randomization to date of first documented tumor progression or death (up to approximately 33 months)

Progression Free Survival (PFS) is defined as the time between the date of randomization and the date of first documented tumor progression, assessed by a blinded independent central review (BICR) (per RECIST v1.1 criteria), or death due to any cause, whichever occurs first. Subjects who die without a reported progression will be considered to have progressed on the date of their death.

Secondary Endpoints
Number of Participants With Adverse Events and Deaths
First dose (Day 1) and 30 days after last dose of study therapy (up to approximately 16 months)
Number of Participants With Laboratory Abnormalities and Immune Mediate Adverse Event
From first dose (Day 1) and up to study completion (up to approximately 45 months)
Overall Survival (OS)
From randomization to the date of death (up to approximately 3 years)
