Eligibility Criteria
Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.
Inclusion Criteria
2. Male or female, aged 18 years or older at the time of signing the ICF.
3. Histologically confirmed with stage IIIB/IIIC or IV (AJCC 8th edition) squamous NSCLC ineligible for surgery or radical radiotherapy.
4. Patients must provide sufficient tumor tissues that meet the quality requirements for the determination of EGFR and PD-L1 expression levels.
Note: Formalin-fixed tumor samples (paraffin blocks or unstained sections, meeting the quality control criteria for testing) collected from lesions that have not received radiotherapy at or after the diagnosis of locally advanced/recurrent or distant metastatic squamous non-small cell lung cancer (sqNSCLC) (from the most recent surgery or biopsy, preferably within half a year prior to randomization) should be provided. Relevant pathology reports must also be provided for the above specimens. For detailed requirements for tissue samples, see the Laboratory Operation Manual.
5. Absence of prior systemic treatment for locally advanced/recurrent or distant metastatic sqNSCLC. Patients who have received prior adjuvant or neoadjuvant therapy are allowed to be enrolled if the adjuvant/neoadjuvant therapy has been completed at least 6 months before the diagnosis of locally advanced/recurrent or distant metastatic sqNSCLC.
6. Prior non-systemic anti-tumor therapy or Chinese herbal anti-tumor therapy must have ended for ≥ 2 weeks before randomization, and treatment-related AEs have resolved to Grade ≤ 1 according to Common Terminology Criteria for Adverse Events (CTCAE) 6.0 (except for Grade 2 alopecia).
7. At least one measurable target lesion assessed by BICR as per RECIST v1.1 within 4 weeks before randomization.
Note: Measurable target lesions cannot be selected from prior radiotherapy sites. A lesion at the prior radiotherapy site may be selected as the target lesion if it is the only available lesion, and should provide the imaging data of the lesion before and after an unequivocal progression after the radiotherapy.
8. An ECOG performance status score of 0 or 1 within 7 days prior to randomization.
9. Life expectancy ≥ 12 weeks.
10. Hepatitis B surface antigen (HBsAg) (-) and hepatitis B core antibody (HBcAb) (-); if HBsAg (+) or HBcAb (+), hepatitis B virus deoxyribonucleic acid (HBV-DNA) must be \< 2,500 copies/mL or 500 IU/mL or within the normal range of this site.
11. HCV antibody (-); if HCV antibody (+), HCV-RNA testing must be negative before enrollment. Participants co-infected with hepatitis B and C will be excluded (tested positive for HBsAg or HBcAb and positive for HCV antibody).
12. Adequate major organ functions as defined by the following criteria
13. Female patients must meet one of the following conditions:
* Post-menopausal (defined as amenorrhea for at least 1 year with no documented cause other than menopause), or
* Surgically sterilized (removal of the ovaries and/or uterus), or
* Fertile, but must:
* be tested negative for serum pregnancy test within 7 days prior to randomization, and
* agree to use contraception with an annual failure rate of \< 1% or to remain abstinent (avoid heterosexual intercourse) from signing the informed consent form to at least 6 months after the last dose of study drugs (contraception with an annual failure rate of \< 1% includes bilateral tubal ligation, male sterilization, correct use of hormonal contraceptives that inhibit ovulation, hormone-releasing intrauterine devices, and copper-containing intrauterine devices), and not donate eggs during this period, and
* not breastfeed.
14. Male patients must: agree to remain abstinent (avoid heterosexual intercourse) or take contraception measures as follows: male patients with a pregnant partner or a partner with childbearing potential must remain abstinent or take contraception measures for contraception during the treatment period with the study drugs and for at least 6 months after the last dose to prevent the drug exposure to the embryo. Periodic abstinence (e.g., contraception based on calendar day, ovulatory phase, basal body temperature, or postovulatory phase) and external ejaculation are ineligible methods of contraception. Sperm donation is prohibited during this period.
15. Patients who have previously received denosumab and are eligible for and agree to switch to bisphosphonates for bone metastases.
Exclusion Criteria
2. Known EGFR-sensitizing mutation, ALK/ROS1 gene rearrangement, or other actionable driver oncogenes for which there are locally approved targeted first-line therapies.
Note: If the EGFR, ALK, ROS1 and other actionable driver oncogenes statuses are unknown, testing is not mandatory, unless there are high-risk factors (such as non-smoking female patients), under which circumstances testing of EGFR and other mutations may be considered.
3. Other malignancies within 5 years or active. Patients with localized tumors that have been cured, such as basal cell carcinoma, squamous-cell skin cancer, superficial bladder carcinoma, prostate carcinoma in situ, cervical carcinoma in situ, and breast cancer in situ, are eligible.
4. Scheduled or previous organ or bone marrow transplantation.

* Patients with asymptomatic brain metastases (i.e., no progressive central nervous system symptoms caused by brain metastases, no requirement for glucocorticoid therapy, and lesion size ≤ 1.5 cm) may be enrolled, but are required to receive regular brain imaging as a site of lesion.
* Patients with treated brain metastases that have been stable for at least 1 month, with no evidence of new or enlarging brain metastases, and with glucocorticoid discontinued ≥ 3 days prior to randomization.
Stable brain metastases should be confirmed before randomization.
