Who can join

Age: 18 and older. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

Male or female, age ≥ 18 years old
Advanced clear cell renal cell carcinoma confirmed by histology or cytology and not amenable to curative surgery.
Has not received any previous systemic anti-tumor treatment for advanced renal cell carcinoma.
Expected survival period is at least 3 months.
ECOG performance status of 0 or 1, or KPS score of at least 70.
Has measurable disease per RECIST 1.1.
Organ function should meet the following criteria:
Absolute neutrophil count (ANC) ≥ 1.5×10\^9/L; Platelet (PLT) ≥90×10\^9/L; Hemoglobin (Hb) ≥ 90 g/L (no blood transfusion or hematopoietic stimulator treatment within 7 days).
Albumin ≥ 30 g/L; Total bilirubin ≤1.5×ULN (for subjects with Gilbert's syndrome, it can be ≤3×ULN); ALT and AST ≤1.5×ULN (If liver metastasis is combined, ALT and AST≤3×ULN).
Creatinine (Cr) ≤1.5 × ULN; Creatinine clearance (Ccr) (to be calculated only when Cr > 1.5× ULN) > 50 ml/min (Cockcroft-Gault formula).
Activated partial thrombin time (APTT) ≤1.5×ULN, International normalized ratio (INR) ≤1.5×ULN.
Voluntarily sign the informed consent form, understand the study and be willing to follow the protocol and complete all experimental procedures.

You may not qualify if…

Documented central nervous system metastases.
Received prior antineoplastic therapy (including chemotherapy, biologic therapy, immunotherapy, or Chinese traditional medicines with antitumor indications) before the first dose of study treatment.
Has received major surgery (grade 3 or 4 as defined in the Measures for the Administration of Clinical Application of Medical Technology) within 28 days before the first dose of study treatment and has not yet recovered from which; or any planned curative surgery for renal cell carcinoma during the study.
History of another malignancy within 5 years before the first dose of study treatment, except for Lung carcinoma in situ, low-risk early-stage prostate cancer, or cured basal-cell carcinoma, squamous-cell carcinoma of the skin, cervical carcinoma in situ, or papillary thyroid carcinoma.
Clinically significant gastrointestinal abnormalities such as malabsorption syndrome, major gastric or small-bowel resection that may affect drug absorption, active peptic ulcer disease, inflammatory bowel disease, ulcerative colitis, or other conditions increasing the risk of perforation; or history of abdominal fistula, gastrointestinal perforation, or intra-abdominal abscess within 28 days before the first dose of study treatment.
Systemic corticosteroids (>10 mg/day prednisone or equivalent) or other immunosuppressive agents required within 2 weeks before the first dose or anticipated during study treatment, except for:
Topical, intranasal, or inhaled corticosteroids.
Corticosteroids as premedication for infusion-related or hypersensitivity reactions (e.g., premedication for CT imaging).
Replacement therapy such as levothyroxine, insulin, or physiologic corticosteroid replacement for adrenal or pituitary insufficiency.
Low-dose corticosteroids for orthostatic hypotension.
Clinically significant cardiovascular or cerebrovascular disease documented by any of the following:
Ischemic stroke (excluding silent lacunar infarction) or severe thromboembolic event within 6 months before the first dose of study treatment.
Myocardial infarction, unstable angina, congestive heart failure, or clinically significant arrhythmia within 6 months before the first dose of study treatment.
New York Heart Association (NYHA) class ≥ II heart failure before the first dose of study treatment.
QTcF interval >450 ms (men) or >470 ms (women) before the first dose of study treatment.
Left-ventricular ejection fraction (LVEF) ≤50 % before the first dose of study treatment.
Prior organ transplant, except corneal transplant; prior allogeneic stem-cell transplant.
Hepatitis B surface antigen (HBsAg) positive with HBV DNA >500 IU/mL or >2,500 copies/mL, or hepatitis C antibody positive with detectable HCV RNA, or known HIV infection, or active tuberculosis.
Interstitial lung disease or non-infectious pneumonitis that is currently symptomatic or has previously required systemic corticosteroids, in the opinion of the investigator likely to interfere with toxicity assessment or management.
Any severe, progressive, or uncontrolled medical condition that, in the investigator's judgment, makes the subject unsuitable for the study, including but not limited to:
Infection requiring systemic therapy.
Symptomatic pleural, pericardial, or ascitic fluid requiring or having undergone drainage within 2 weeks before the first dose (minimal asymptomatic effusion, third-spacing due to hypoalbuminaemia, or cases where benefit outweighs risk may be allowed).
History of coagulopathy (e.g., deep-vein thrombosis) or severe bleeding diathesis; clinically significant bleeding event (e.g., gastrointestinal bleeding) within 1 month before the first dose.
History of severe psychiatric disorder.
Any other condition that, in the investigator's opinion, renders study participation riskier than beneficial.
