Ociperlimab With Tislelizumab and Chemotherapy in Patients With Untreated Metastatic Non-Small Cell Lung Cancer

Key Inclusion Criteria:

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.
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.
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.

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

.

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

Key Exclusion Criteria:

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
Prior treatment with EGFR inhibitors, ALK inhibitors, or targeted therapy for other driver mutations.
Any prior therapy targeting T-cell costimulation or checkpoint pathways in metastatic NSCLC.
Any condition that required systemic treatment with either corticosteroids (> 10 mg daily of prednisone or equivalent) or other immunosuppressive medication ≤ 14 days before randomization.
Infection (including tuberculosis infection, etc.) requiring systemic antibacterial, antifungal, or antiviral therapy within 14 days before randomization.
