20. Examinations (physical examination, X-ray examination, type-B ultrasonic detection or other methods) reveal that the subject has malignant mass, gland hyperplasia or adenoma with endocrine activity, or impact on heart, or endocrine function (such as pheochromocytoma, thyroid enlargement);
21. The Investigator deemed for whatever reason that the subject is not likely to complete the study or comply with the study procedures (due to administration or any other reason).
