AdvanTIG-205: A Phase 2, Randomized, Study of Ociperlimab (BGB-A1217) and Tislelizumab With Chemotherapy in Patients With Previously Untreated Locally Advanced, Unresectable, or Metastatic Non-Small Cell Lung Cancer (NSCLC)

Key Inclusion Criteria:

1. Histologically or cytologically documented locally advanced or recurrent NSCLC that is not eligible for curative surgery and/or definitive radiotherapy, with or without chemotherapy, or metastatic non-squamous or squamous NSCLC.
2. No prior systemic therapy for locally advanced or metastatic squamous or non-squamous NSCLC, including but not limited to chemotherapy or targeted therapy. Patients who have received prior neoadjuvant, adjuvant chemotherapy, or chemoradiotherapy with curative intent for nonmetastatic disease must have experienced a disease-free interval of ≥ 6 months from the last dose of chemotherapy and/or concurrent radiotherapy prior to randomization.
3. Archival tumor tissue or fresh biopsy (if archival tissue is not available) for the determination of PD-L1 levels and retrospective analyses of other biomarkers. Only patients who have evaluable PD-L1 results are eligible.

4. At least one measurable lesion by the investigator per RECIST v1.1.

   .

5. Eastern Cooperative Oncology Group (ECOG) Performance Status ≤ 1.

Key Exclusion Criteria:

1. Known mutations in:

   • EGFR gene Note: For non-squamous NSCLC, patients with unknown EGFR mutation status will be required to have a tissue-based EGFR test either locally or at the central laboratory before enrollment, or endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA)-based EGFR test locally. Patients found to have EGFR-sensitizing mutations will be excluded.
   • ALK fusion oncogene.
   • BRAF V600E
   • ROS1
2. Prior treatment with EGFR inhibitors, ALK inhibitors, or targeted therapy for other driver mutations.
3. Any prior therapy targeting T-cell costimulation or checkpoint pathways in metastatic NSCLC.
4. Any condition that required systemic treatment with either corticosteroids (> 10 mg daily of prednisone or equivalent) or other immunosuppressive medication ≤ 14 days before randomization.
5. Infection (including tuberculosis infection, etc.) requiring systemic antibacterial, antifungal, or antiviral therapy within 14 days before randomization.

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