Male participants must also agree to use contraception during the study period and for 6 months after. Additionally, female participants must have a negative serum or urine pregnancy test within 7 days prior to study entry and should not be breastfeeding.

Exclusion Criteria:

1. Patients with previous use of cardunilizumab.

2. non-small cell lung cancer (including lung cancer with a mixture of small cell and non-small cell carcinoma).

3. Patients with other types of cancer that occurred within the past 5 years or are currently present, with the exception of treated cervical carcinoma in situ, non-melanoma skin cancer, and superficial bladder tumors that have not invaded the basement membrane (Ta, Tis, and T1).

4. Systemic antitumor therapy, including cytotoxic therapy, signal transduction inhibitors, immunotherapy, within 4 weeks prior to enrollment or planned during the current study dosing period (or have used mitomycin C within 6 weeks prior to treatment with the trial drug). Have had extended field radiotherapy (EF-RT) within 4 weeks prior to subgroup or have had field-limited radiotherapy to the tumor lesion to be evaluated within 2 weeks prior to subgroup.

5. Unremitted toxic reactions due to any prior treatment above CTCAE grade 1, excluding alopecia and neurotoxicity ≤ grade 2 due to oxaliplatin.

6. Individuals with various factors such as difficulty swallowing, chronic diarrhea, and intestinal obstruction may experience challenges with oral drug administration.

7. with pleural effusion or ascites causing respiratory syndrome (≥ CTCAE grade 2 dyspnea).

8. Patients with brain metastases with symptoms or symptoms controlled for less than 2 months.

9. Patients with any severe and/or uncontrolled disease, including:

1. Patients with poorly controlled blood pressure (systolic blood pressure ≥ 150 mmHg and diastolic blood pressure ≥ 100 mmHg).

2. Patients with myocardial ischemia of grade I or higher, myocardial infarction, arrhythmias (including QTc ≥ 480 ms), and congestive heart failure of grade 2 or higher (categorized according to the New York Heart Association (NYHA) classification) are included.

3. Active or uncontrolled serious infection (≥ CTC AE grade 2 infection).

4. Cirrhosis, decompensated liver disease, active hepatitis or chronic hepatitis requiring antiviral therapy.

5. Renal failure requiring hemodialysis or peritoneal dialysis.

6. This refers to a medical history of immunodeficiency, which can be acquired through HIV or other diseases, or congenital in nature. It also includes a history of organ transplantation.

11.Patients whose imaging shows that the tumor has invaded the critical vascular perimeter or who, in the judgment of the investigator, are at high risk of fatal hemorrhage due to tumor invasion of a critical vessel during the follow-up study.

12.Patients with any physical signs or history of bleeding, regardless of severity; patients with any bleeding or hemorrhagic event ≥ CTCAE grade 3, unhealed wounds, ulcers or fractures within 4 weeks prior to subgroup.

13.Individuals who have experienced an arterial or venous thrombotic event within the past 6 months, including cerebrovascular accidents (including temporary ischemic attacks), deep vein thrombosis, and pulmonary embolisms, should take caution.

14.Individuals with a history of psychotropic substance abuse or psychiatric disorders who are unable to abstain.

15.having participated in clinical trials of other antineoplastic drugs within four weeks.

16.Patients with concomitant diseases that are deemed to pose a significant risk to their safety or may hinder their ability to complete the study, as determined by the investigator, will be excluded.
