* Work with long-term exposure to radioactive conditions; or marked exposure to radioactivity (chest/abdomen CT ≥ 2 times, or other kinds of X-ray examinations ≥ 3 times) or participation in any radioactive labeling trial within 1 year before the trial;
* History of fear of needles and blood, difficult blood sampling, or incapability of tolerating blood sampling via venipuncture;
* Participation in any other clinical trial (including drug and device clinical trials) within 3 months before screening;
* Vaccination within 1 month before Screening or planned vaccination during the trial period;
* Subjects who have a plan for parenthood or sperm donation from the signing of informed consent to 1 year following the completion of the trial, or those who do not agree that subjects and their partners should use strict contraception from the signing of informed consent to 1 year following the completion of the trial;
* Blood loss or blood donation up to 400 mL (≥ 400 mL) within 3 months before Screening, or blood transfusion within 1 month before screening;
* Subjects who have any factors that make them not suitable for participating in this trial, as assessed by the investigator.
