        • Hypertension, which cannot be well controlled by antihypertensive drugs (systolic blood pressure> 140 mmHg or diastolic blood pressure> 90 mmHg).
        • Systemic use of antibiotics for ≥ 7 days within 4 weeks before enrollment, or unexplained fever > 38.5 ° C during screening / before the first administration (according to the judgment of the investigator, fever caused by tumor can be enrolled) .
