• •5. The patient had not received systemic antitumor therapy.
• •6. Patients who had received one prior chemotherapy regimen were allowed, regardless of whether chemotherapy was administered before, after, or concurrently with targeted therapy.
• •7. Patients receiving adjuvant or neoadjuvant therapy were allowed if adjuvant/neoadjuvant therapy had been completed at least 12 months before diagnosis of advanced or postoperative recurrent NSCLC.

• •9. have at least one measurable target lesion as assessed by the investigator according to iRECIST requirements within 4 weeks before enrollment.
• •10. If available, patients can provide eligible tumor tissue for PD-L1 expression level measurement.
• •11. an ECOG PS score of 0 or 1 within 7 days before the first dose of study medication.
• •12. predicted survival time ≥12 weeks (3 months).
• •13. had good major organ function, defined as meeting the following criteria, and had not received blood transfusions, albumin, recombinant human thrombopoietin, or colony-stimulating factor (CSF) within 14 days before the first dose of study medication.
• •14. Female patients must meet one of the following conditions:
• •(1)menopause, defined as absence of menses for at least 1 year and no confirmed cause other than menopause, or (2) having undergone sterilization (removal of ovaries and/or uterus) 3) be fertile, provided that: Patients had to have a negative serum pregnancy test within 7 days before randomization and agree to use contraception with an annual failure rate of \<1% or to abstain from heterosexual intercourse for at least 120 days from the date of written informed consent until the last dose of trial drug was administered. At least 150 days after the last dose of chemotherapy) (contraceptive methods with an annual failure rate of \<1% include bilateral tubal ligation, male sterilization, proper use of ovulation-suppressing hormonal contraceptives, hormone-releasing intrauterine devices, and copper intrauterine devices or condoms), and Do not breastfeed.
• •15.Male patients had to agree to either abstain from sex (avoid heterosexual intercourse) or to use contraception, as specified by either abstinence or use of condoms to prevent exposure of the drug to the embryo during chemotherapy (paclitaxel/pemetrexed/carboplatin) for the duration of treatment with a woman of reproductive age or a pregnant partner and for at least 150 days after the last dose of chemotherapy. Regular abstinence (e.g., calendar day, ovulation, basal body temperature, or postovulatory methods of contraception) and in vitro ejaculation are ineligible methods of contraception.

• •8\. received definitive thoracic radiotherapy within 28 days before enrollment; Subjects who received palliative radiotherapy to a bone lesion outside the chest within 2 weeks before receiving the first dose of study drug.
• •9\. severe unhealed wound ulcers or fractures, or major surgery within 28 days before randomization or expected to undergo major surgery during the study period.
• •10.Any unstable systemic disease: These included, but were not limited to, active pulmonary tuberculosis, active infection, unstable angina, cerebrovascular accident or transient ischemic attack (within 6 months before screening), myocardial infarction (within 6 months before screening), and congestive heart failure (New York Heart Association \[NYHA\] class ≥ 2 Grade II), severe cardiac arrhythmias requiring medical therapy, and hepatic, renal, or metabolic disorders 11. poorly controlled hypertension (defined as systolic blood pressure (BP) ≥160 mmHg and/or diastolic blood pressure ≥100 mmHg) with a history of hypertensive crisis or hypertensive encephalopathy.
