Experimental: Eligible patients
tislelizumab (200mg) in combination with pemetrexed (500mg/m2) and carboplatin (AUC=5) intravenously on day 1 of a 3-week cycle for 4 cycles. Afterwards, patients without disease progression were treated with maintenance treatment with tislelizumab (200mg) plus pemetrexed (500mg/m2) every 3 weeks up to 24 months or until disease progression, unacceptable toxicity, or death.

- Overall Survival (OS) [ Time Frame: 36 months ]OS is defined as the time from the starting date of study drug to the date of death due to any cause
- Progression-free survival (PFS) according to RANO-BM [ Time Frame: 36 months ]PFS2 is defined as the time from first intracranial disease progression to second/subsequent disease progression (intracranial or extracranial) after initiation of new anti-cancer therapy, or death from any cause, whichever occurs first
- Duration of Response (DoR) according to RECIST v1.1 [ Time Frame: 36 months ]DoR is defined as the time from the date for first documented response of complete response (CR) or partial response (PR) to the date of first documented of disease progression or death, whichever occurs first
- Incidence and severity of treatment-emergent AEs (TEAEs) [ Time Frame: 36 months ]TEAEs graded according to National Cancer Institute-Common Terminology Criteria for Adverse Events (NCI-CTCAE) v5.0
- Neurocognitive impairment [ Time Frame: 36 months ]Neurocognitive impairment according to Hopkins Verbal Learning Test-Revised（HVLT-R）
- PD-L1 expression, TMB, and other potential predictive biomarkers, correlated with response to treatment [ Time Frame: 36 months ]

|Ages Eligible for Study:||18 Years to 75 Years (Adult, Older Adult)|
|Sexes Eligible for Study:||All|
|Accepts Healthy Volunteers:||No|
Disease-related inclusion criteria:
- Histologically confirmed metastatic (Stage IV) not amenable to curative surgery or radiotherapy, non-squamous NSCLC according to American Joint Committee on Cancer (AJCC), 8th Edition.
- Radiographically confirmed brain metastases;
- No prior systemic treatment for stage IV NSCLC. (Bevacizumab administered for improving radiation-induced encephaledema during irradiating intracranial lesions is not considered as systemic therapy for stage IV NSCLC)
- Patients with asymptomatic BM or symptoms can be controlled by low dose corticosteroids (≤ 10 mg/day of prednisone or equivalent) or antiepileptics drugs;
- Patients with previous local treatment to BMs should be stable and suitable to receive the systemic treatment;
- ECOG PS: 0 ~ 1
- Extracranial measurable target lesions (per RECIST v1.1)
Life expectancy ≥ 3 months
Have adequate hematology, clinical chemistry, and organ function as indicated by the following laboratory values (confirmed within 7 days prior to the first dose):
- Absolute neutrophil count (ANC) ≥ 1.5 × 109/L, platelets ≥ 100 × 109/L, hemoglobin ≥ 90 g/L.
- International normalized ratio (INR) or prothrombin time (PT) ≤ 1.5 × upper limit of normal [ULN].
- Activated partial thromboplastin time (aPTT) ≤ 1.5 × ULN.
- Serum total bilirubin ≤ 1.5 × ULN (total bilirubin must be < 3 × ULN for patients with Gilbert's syndrome).

- Male or female, aged 18 ~ 75 years on the day of signing ICF. Female patients of childbearing potential and non-sterile male patients must be willing to use a highly effective method of birth control for the duration of the study and for at least 120 days after the last dose of tislelizumab.
Disease-related exclusion criteria:
- Received prior therapies targeting PD-1, PD-L1, CTLA-4 or other immune checkpoints inhibitors.
- Received prior systemic chemotherapy for advanced disease.
- Have EGFR mutation or ALK gene translocation.
- Patients iwith BMs that have received systemic treatment with corticosteroids (>10 mg/day of prednisone or equivalent) or other drugs to relieve or prevent symptoms of BMs.
- Patients with intracranial metastases that are locally amenable.
- Have received any approved systemic anticancer therapy or systemic immunomodulators (including but not limited to interferon, interleukin-2, and tumor necrosis factor) within 4 weeks prior to the first dose of study drug.
