Tislelizumab in Combination With Sitravatinib in Participants With Locally Advanced or Metastatic Non-Small Cell Lung Cancer

Progression Free Survival (PFS) as Assessed by the Investigator

Defined as the time from randomization until first documentation of disease progression as determined by the investigator based on RECIST v1.1, or death from any cause, whichever occured first. Kaplan-Meier methodology was used to estimate the median PFS.

Time frame: Until the study completion data cut-off date of December 20, 2023, or the last available date confirming participants were alive (a median follow-up of approximately 8 months).

Overall Response Rate (ORR)

Defined as the percentage of participants with a confirmed complete response (CR) or partial response (PR) as assessed by the IRC per RECIST v1.1.

Time frame: Until the study completion data cut-off date of December 20, 2023, or the last available date confirming participants were alive (a median follow-up of approximately 8 months).

Duration of Response (DOR)

Defined as the time from the first occurrence of a documented objective response to the time of the first occurrence of disease progression, as determined by the IRC based on RECIST v1.1, or death from any cause, whichever occurs first.

Time frame: Until the study completion data cut-off date of December 20, 2023, or the last available date confirming participants were alive (a median follow-up of approximately 8 months).

Disease Control Rate (DCR)

Defined as the percentage of participants whose best overall response (BOR) is complete response, partial response, or stable disease per RECIST v1.1.

Time frame: Until the study completion data cut-off date of December 20, 2023, or the last available date confirming participants were alive (a median follow-up of approximately 8 months).

Change From Baseline in European Organization for the Research and Treatment of Cancer Quality of Life Questionnaire Core 30 (EORTC QLQ-C30) Global Health Status (GHS) and Physical Functioning Scores

The EORTC QLQ-30 contains 30 questions that incorporate 5 functional scales (physical functioning, role functioning, emotional functioning, cognitive functioning, and social functioning), 1 global health status scale, 3 symptom scales (fatigue, nausea and vomiting, and pain), and 6 single items (dyspnea, insomnia, appetite loss, constipation, diarrhea, and financial difficulties). The participant answers questions about their health during the past week. There are 28 questions answered on a 4-point scale where 1 = Not at all (best) and 4 = Very Much (worst) and 2 global health quality of life (QOL) questions answered on a 7-point scale where 1 = Very poor and 7 = Excellent. Raw scores are transformed into a 0 to 100 scale via linear transformation. Higher scores in GHS and functional scales indicate better quality of life.

Time frame: Baseline and Cycle 5 Day 1 (Week 12) and Cycle 7 Day 1 (Week 18)

Change From Baseline in EORTC Quality of Life Questionnaire-Lung Cancer 13 (QLQ-LC13) Coughing, Dyspnoea, and Chest Pain Scales

The EORTC QLQ-LC13 is the lung cancer module of the QLQ-C30 and measures lung cancer-specific disease and treatment symptoms. It includes 13 questions about specific symptoms in which participants respond based on a 4-point scale, where 1 is "not at all" and 4 is "very much". Raw scores are transformed into a 0 to 100 scale via linear transformation. Lower scores indicate an improvement in symptoms.

Time frame: Baseline and Cycle 5 Day 1 (Week 12) and Cycle 7 Day 1 (Week 18)

Change From Baseline in European Quality of Life-5 Dimensions (EQ-5D-5L) Visual Analogue Scale (VAS)

The EQ-5D-5L comprises a descriptive module that includes five dimensions: mobility, self-care, usual activities, pain/discomfort and anxiety/depression and a Visual Analogue Scale. Each dimension has 5 levels: no problems, slight problems, moderate problems, severe problems and extreme problems. The VAS records a participant's self-rated health on a vertical scale from 0 to 100, where 0 is 'the worst health you can imagine and 100 is 'the best health you can imagine'. A higher score indicates better health outcomes.

Time frame: Baseline and Cycle 5 Day 1 (Week 12) and Cycle 7 Day 1 (Week 18)

Number of Participants With Adverse Events

Number of participants with treatment-emergent adverse events (TEAEs) and serious adverse events (SAEs), according to National Cancer Institute-Common Terminology Criteria for Adverse Events (NCI-CTCAE) v5.0

Time frame: From the first dose through 30 days after the final dose or until new anticancer therapy, whichever came first, (a median treatment duration of approximately 4 months in Arm 1 and 2 months in Arm 2).
