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

A Randomized Phase 3 Study of Tislelizumab in Combination With Sitravatinib in Patients With Locally Advanced or Metastatic Non-Small Cell Lung Cancer That Progressed on or After Platinum-Based Chemotherapy and Anti-PD-(L)1 Antibody

The purpose of this study was to evaluate the efficacy and safety of tislelizumab in combination with sitravatinib compared to docetaxel in participants with locally advanced or metastatic non-small cell lung cancer (NSCLC) who experienced disease progression following platinum-based chemotherapy and anti-programmed cell death protein-1 (PD-1)/programmed cell death ligand-1 (PD-L1) antibody treatment, with the anti-PD-(L)1 antibody administered either in combination with or sequentially before or after the platinum-based chemotherapy.

Key Inclusion Criteria:

1. Metastatic or unresectable locally advanced histologically or cytologically confirmed Non-Small Cell Lung Cancer (NCSLC), not amenable to treatment with curative intent
2. Able to provide archival/fresh tumor tissues for biomarker analysis to assess PD-L1 expression and other biomarkers.
3. No known Epidermal Growth Factor Receptor (EGFR) or B-Raf proto-oncogene (BRAF) sensitizing mutation, or anaplastic lymphoma kinase (ALK) rearrangement or ROS proto oncogene 1 (ROS1) rearrangement
4. Radiographic progression per Response Evaluation Criteria in Solid Tumours (RECIST) v1.1 on or after anti-PD-(L)1 containing therapy for locally advanced and unresectable or metastatic NSCLC.
5. No prior anticancer therapy having the same mechanism of action as sitravatinib (eg, tyrosine kinase inhibitor with a similar target profile or vascular endothelial growth factor (VEGF)- or VEGFR inhibitor)
6. At least 1 measurable lesion as defined based on RECIST v1.1 by investigator

Key Exclusion Criteria:

1. Has received docetaxel as monotherapy or in combination with other therapies.
2. Squamous NSCLC with central cavitation, or NSCLC with hemoptysis (> 50 mL/day)
3. Participants with tumor shown by imaging to be located around important vascular structures or if the investigator determines that the tumor is likely to invade important blood vessels and may cause fatal bleeding.
4. Active leptomeningeal disease for metastatic NSCLC, or uncontrolled or untreated brain metastasis.
5. Active autoimmune diseases or history of autoimmune diseases that may relapse.

NOTE: Other protocol defined Inclusion/Exclusion criteria may apply.
