Radiotherapy for the relief of metastatic bone pain prior to enrollment is permitted, provided that no more than 30% of the total marrow-containing bone is irradiated, with the exception of patients with good bone feel prior to treatment;
• Current or recent (within 30 days prior to enrollment) use of another investigational drug or participation in another clinical study
• Have had clinically significant bleeding symptoms or a definite bleeding tendency within the previous 3 months, such as gastrointestinal bleeding, bleeding gastric ulcer, fecal occult blood +++ or more at baseline, or have vasculitis
• Have undergone major surgical procedures or have sustained a severe traumatic injury, fracture, or ulcer within the previous 4 weeks
• Having factors that significantly affect the absorption of oral medication, such as inability to swallow, chronic diarrhea and intestinal obstruction, etc;
• Plasmapheresis (including pleural fluid, ascites, and pericardial effusion) that is clinically symptomatic and requires surgical management;

Más betegség

• Uncontrolled hypertension (systolic blood pressure ≥ 140 mmHg or diastolic blood pressure ≥ 90 mmHg despite optimal pharmacologic therapy)
• Other conditions that, in the judgment of the investigator, may affect the conduct of the clinical study and the determination of the study results.
