therapy within 2 weeks before screening; However, the restriction for Nitroso urea or
Mitomycin C are within 6 weeks before screening;
5. Subjects received chronic systemic sex hormone treatment for any reason within 12
weeks before screening; However, the use of low-dose glucocorticoid replacement
therapy due to adrenal cortex dysfunction is exempted.
