Korábbi kezelés

• Prior local treatment including radiofrequency ablation, microwave ablation, radiotherapy or other local therapies for metastatic lesions.
• Current participation in other interventional clinical studies and receiving investigational treatment.
• Diagnosis of any other malignant disease within 5 years prior to the first study drug administration (excluding radically treated basal cell carcinoma, squamous cell carcinoma of the skin, and/or radically resected in situ carcinoma).
• Prior history of solid organ or hematopoietic stem cell transplantation.
• Any disease requiring systemic treatment with corticosteroids (prednisone or equivalent daily dose > 10 mg) or other immunosuppressive agents within 14 days prior to enrollment.
• Previous or current diagnosis of brain metastases with incompletely controlled symptoms (i.e., persistent or aggravated symptoms, or requirement for adjusted symptomatic treatment to maintain symptom relief).
• Prior systemic pharmacotherapy, radiotherapy or local hepatic treatment with an interval of < 1 month from the last systemic or local hepatic treatment to the first study drug administration.

Más betegség

• Presence of uncontrolled active infection.
• History of esophagogastric variceal rupture without effective treatment via endoscopy, interventional therapy or surgery.
• Patients with psychiatric disorders in the acute episode stage.

Laborértékek

• Renal dysfunction defined as serum creatinine > 176.8 μmol/L or creatinine clearance < 30 mL/min.
• Uncorrectable coagulation abnormalities, including platelet count < 50×10⁹/L, prothrombin time > 18 seconds, or prothrombin activity < 40%, which cannot be corrected.

Egyéb
