• Known hypersensitivity to any study drug; 2) known or suspected central nervous system metastases, defined as signs or symptoms suggestive of CNS metastasis, unless CNS metastasis has been excluded by CT or MRI; 3) history of other malignancies within 5 years, except adequately treated basal cell carcinoma of the skin or carcinoma in situ of the cervix; 4) requiring any concomitant anticancer treatment other than the study treatment during the study, including chemotherapy, targeted therapy, hormonal therapy, immunotherapy, radiotherapy, or traditional Chinese medicine with antitumor activity; 5) prior or current treatment with chemotherapy, FAK inhibitors, or antibodies targeting PD-1, PD-L1, PD-L2, CD137, or cytotoxic T-lymphocyte-associated antigen 4 (CTLA-4), including ipilimumab or any other antibody or drug targeting T-cell costimulatory or checkpoint pathways; 6) diagnosis of immunodeficiency or chronic systemic corticosteroid therapy (prednisone >10 mg/day or equivalent) or any other form of immunosuppressive therapy within 7 days before the first dose of study treatment; 7) receipt of a live vaccine within 30 days before the first dose of study treatment, including but not limited to measles, mumps, rubella, varicella/zoster, yellow fever, rabies, Bacillus Calmette-Guérin (BCG), and typhoid vaccines; inactivated seasonal influenza vaccines are permitted, whereas live attenuated vaccines such as intranasal influenza vaccines (e.g., FluMist) are not permitted; 8) uncontrolled hypertension, defined as systolic blood pressure >160 mmHg and/or diastolic blood pressure >100 mmHg despite treatment; 9) significant cardiac disease, including congestive heart failure (NYHA class III-IV), previous myocardial infarction, or uncontrolled angina within 6 months; 10) clinically significant arrhythmias requiring treatment, including atrial fibrillation, supraventricular tachycardia, ventricular tachycardia, or ventricular fibrillation, or ECG abnormalities confirmed on repeat examination that, in the investigator's judgment, require clinical intervention or treatment; 11) history of hemorrhagic or thromboembolic events within the past 6 months, such as cerebrovascular accident (including transient ischemic attack), pulmonary embolism, or spontaneous major tumor-related bleeding; 12) surgery required within 28 days before or anticipated within 28 days after the last dose of study treatment; 13) uncontrolled third-space fluid accumulation, such as large pleural effusion or ascites; 14) definite gastrointestinal bleeding tendency within 4 weeks before the first dose, including: ① active localized ulcerative lesions with positive fecal occult blood; ② melena or hematemesis within 28 days; or ③ positive fecal occult blood in patients with unresected tumor invasion of the gastrointestinal tract who, in the opinion of the principal investigator at the study center, may be at risk of major gastrointestinal bleeding; 15) previous gastrointestinal perforation or suspected risk of gastrointestinal perforation, or intestinal obstruction; 16) concomitant medications that, in the investigator's judgment, are required during the trial and may affect the metabolism of the investigational drug, such as strong CYP3A4 inhibitors or inducers, or drugs with a narrow therapeutic index that are primarily metabolized by CYP3A4, CYP2C8, CYP2C9, CYP2C19, or CYP2D6; 17) severe psychiatric disorders; 18) women who are pregnant, breastfeeding, or potentially pregnant; 19) women or men of childbearing potential unwilling to use effective contraception during the study and for 3 months after the last dose of study treatment; 20) participation in another clinical trial of a drug or medical device within 4 weeks before enrollment; 21) any other condition that, in the investigator's judgment, makes the patient unsuitable for enrollment
