16. Amenable to computed tomography (CT) with 3 or 4 phase liver or magnetic resonance imaging (MRI) of abdomen and pelvis, and CT of chest, or MRI of whole body, for initial tumor size measurements and subsequent follow-up
17. Absence of other clinically relevant abnormalities (i.e., those which do not require medical intervention) for screening laboratory test results as judged by the Investigator and Sponsor
18. Willingness and ability to comply with scheduled visits, treatment plan, laboratory tests, and other study procedures
19. Able to understand and provide written informed consent

20. Patients covered by Health Insurance System

    • According to CTFG guideline, a woman is considered of childbearing potential (WOCBP), i.e. fertile, following menarche and until becoming post-menopausal unless permanently sterile. Permanent sterilization methods include hysterectomy, bilateral salpingectomy and bilateral oophorectomy ** Highly effective birth control method include (according to CTFG guideline): combined (estrogen and progestogen containing) hormonal contraception associated with inhibition of ovulation (oral, intravaginal, transdermal); progestogen-only hormonal contraception associated with inhibition of ovulation (oral, injectable, implantable); intrauterine device; intrauterine hormone-releasing system; bilateral tubal occlusion; vasectomized partner; sexual abstinence.
