-
Known HER2-positive expression (immunohistochemistry [IHC] 3+ or 2+ with a fluorescence in situ hybridization HER2:CEP17 ratio ≥2).
-
Presence of other malignancies within 5 years prior to treatment, with the exception of adequately treated cervical carcinoma in situ, basal cell or squamous cell carcinoma of the skin, locally treated prostate cancer, and ductal carcinoma in situ (hormone therapy for non-metastatic prostate cancer or breast cancer is permitted).
-
Known central nervous system metastases and/or carcinomatous meningitis.
-
Patients with severe cardiac, pulmonary, hepatic, or renal dysfunction.
-
Hypertension that cannot be controlled with antihypertensive medications (systolic blood pressure >140 mmHg, diastolic blood pressure >90 mmHg).
-
History of bleeding within 4 weeks prior to screening, with any bleeding event graded as ≥3 according to CTCAE 5.0.
-
Thrombotic events (arterial or venous) within 6 months prior to screening, such as cerebrovascular accident, deep vein thrombosis (excluding previously thrombosed veins deemed healed by the investigator), and pulmonary embolism.
