• Interferon was received within 4 weeks prior to the initiation of the investigational treatment; or chemotherapy was received within 4 weeks prior to the initiation of the investigational treatment; or transarterial chemoembolization was received within 12 months prior to screening; or previously received peptide receptor radionuclide therapy (PRRT) at any time; or received radiation therapy, anti-tumor traditional Chinese medicine treatment, hepatic artery intervention embolization, liver metastasis cryoablation or radiofrequency ablation, and other systemic anti-tumor drug treatments within 4 weeks prior to the initiation of the investigational treatment; or had participated in other clinical trials within 30 days prior to screening
• Surgery (except biopsy) within 28 days prior to the initiation of investigational treatment or unhealed surgical incision;
• Patients with active brain metastases or cancerous meningitis meet any of the following criteria: a) Patients with prior brain metastases, imaging within 4 weeks prior to the first use of investigational drug show progression of the original lesion, or new brain metastases; b) Clinical symptoms associated with central nervous system metastasis did not recovery to baseline; c) Use cortisols, radiotherapy and other drugs to control the symptoms of central nervous system metastasis within 4 weeks before the first use of the investigational drug;
• The adverse reactions of previous antitumor therapy have not returned to ≤ grade 1 according to CTCAE V5.0 (except that the investigators evaluate no safety risk, such as hair loss, grade 2 peripheral neuropathy or dysfunction);
• A history of allergy to any excipient of the investigational drug or any similar chemical structure to the investigational drug;

Más betegség

• Patients have symptomatic cholelithiasis or a history of symptomatic cholelithiasis at screening, but with no performed surgery treatment;

Laborértékek

• Glycated hemoglobin (HbA1c) > 8.5%;
• Any clinically significant uncontrolled neurological, gastrointestinal, renal (serum creatinine > 1.5 ULN), pulmonary, or other significant disease requiring exclusion assessed in the opinion of the Investigator;
• Patients had hepatitis B virus (HBV) infection with HBV DNA positive (copies ≥1×10\^4/ml or ≥2000 IU/ml); known Hepatitis C antibodies positive and HCV RNA higher than the lower detection limit ; or human immunodeficiency virus (HIV) positive, treponema pallidum antibody positive;.
• Patients had any severe or uncontrolled disease, including: 1) poor blood pressure control (systolic ≥160 mmHg or diastolic ≥100 mmHg);2) grade I or higher myocardial ischemia or myocardial infarction, symptomatic or poorly controlled arrhythmia, or congenital long QT syndrome (including QTcF ≥450ms for males, QTcF ≥470ms for females), or ≥ Grade 2 congestive heart failure [NYHA classification]; 3) serious infections that are not under control (oral or intravenous systemic anti-infection therapy is required for 2 weeks before the first use of the investigational drug, except for uncomplicated urinary tract infections and upper respiratory tract infections);4) previous or current severe bleeding (>30ml of bleeding within 3 months), hemoptysis (>5ml of fresh blood within 4 weeks), or thromboembolic events (including transient ischemic attacks) within 12 months;
• Other disease, metabolic disorder, physical examination anomaly, abnormal laboratory result, or any other conditions are inappropriate for the use of the investigational product or affect interpretation of study results.
