Subjects in whom central nervous lymphoma is recognized during the screening period (If brain metastasis is suspected clinically, CT should be performed.)~2. Subjects undergoing chemotherapy or immunotherapy for the purpose of treatment of the target disease within 22 days before C1D1 (including C1D1) (using antibody drugs only within 3 months before C1D1)~3. Subjects receiving local application of steroids within 15 days before C1D1 (including C1D1) Use of steroids for the purpose other than that of treatment of the target disease should be allowed (Only CTCL subjects)~4. Subjects receiving systemic application of steroids within 22 days before C1D1 (including C1D1) (It is acceptable to continue the use of the steroid for the purpose of treatment of the target disease,which administered in doses ≤ 10mg/day prednisolone or equivalent dose of other glucocorticoid. However increase of steroid dose cannot be allowed during the study period)~5. Subjects undergoing radiation therapy, PUVA therapy or TSEB for the purpose of treatment of the target disease within 22 days before C1D1 (including C1D1)~6. Subjects using other investigational products within 22 days before C1D1 (including C1D1) (using antibody drugs only within 3 months before C1D1)~7. Subjects undergoing blood transfusion and using G-CSF within 8 days before C1D1 (including C1D1)~8. Subjects with the following abnormalities in the cardiac function~   1. Congenital QT prolongation syndrome~  2. QTc interval \>480 msec~  3. Myocardial infarction within 6 months before C1D1. Subjects with a history of myocardial infarction between 6 and 12 months prior to C1D1 who are asymptomatic and have had a negative cardiac risk assessment (treadmill stress test, nuclear medicine stress test, or stress echocardiogram) since the event may occur~  4. Significant ECG abnormalities including atrio-ventricular (AV) block type II, 3rd degree AV block, or bradycardia (ventricular rate less than 50 beats/min)~  5. Symptomatic coronary artery disease (CAD) (e.g., Angina Canadian Class II-IV).~  6. An ECG recorded at screening showing significant ST depression (ST depression of ≥2 mm, measured from isoelectric line to the ST segment at a point 60 msec at the end of the QRS complex). If there is any doubt, the subject should have a stress imaging study and, if abnormal, angiography to define whether or not CAD is present.~  7. Congestive heart failure (CHF) that meets New York Heart Association (NYHA) Class II to IV definitions and/or ejection fraction \<40% by MUGA scan or \<50% by echocardiogram and/or MRI~  8. A known history of sustained ventricular tachycardia (VT), ventricular fibrillation (VF), torsade de pointes, or cardiac arrest unless currently addressed with an automatic implantable cardioverter defibrillator (AICD)~  9. Hypertrophic cardiomyopathy or restrictive cardiomyopathy from prior treatment or other causes (if there is any doubt, see ejection fraction criteria above)~  10. Uncontrolled hypertension, i.e., systolic blood pressure (BP) is greater than or equal to 160 mmHg or diastolic BP is greater than or equal to 95 mmHg; subjects who have a history of hypertension controlled by medication must be on a stable dose (for at least one month)~  11. Subjects with cardiac arrhythmia requiring an anti-arrhythmic drug~9. Concomitant use of a drug which may induce significant QT prolongation (refer to 9.2. Prohibited Concomitant Medications and Procedures.)~10. Concomitant use of strong or moderate CYP3A4 inhibitors which include grapefruit juice~11.

Known infection with human immunodeficiency virus (HIV) antibody positive, HBs antigen positive or HCV antibody positive. If negative for HBsAg but HBcAb and/or HBsAb positive status, a HBV DNA test will be performed and if positive the subject will be excluded.~15. Subjects undergoing a wide range of radiation therapy in ≥30% of the bone marrow (such as all parts of the pelvic area or a half of the spinal cord) in the past. The subjects undergoing systemic radiation (including systemic electron therapy) as previous treatment for ASCT will be excluded.~16. Subjects undergoing a surgery within 15 days before C1D1 (including C1D1); however, even if more than 15 days have passed since the surgery, subjects without evidence of wound healing will be excluded.~17. Subjects who are during recovery process from severe wound or fracture.~18. Subjects with a history of allogeneic stem cell transplantation~19. Patients who are breast-feed during period of the IP administration or within 28 days after the end of the IP administration.~20. Subjects with a history of any other malignant tumor or solid cancer within previous 3 years (excluding basal or squamous cell carcinoma of skin, and in situ carcinoma of the cervix (CIN3) that has been treated curatively)~21. Subject with a history of hematological malignant tumor (other than T-cell lymphoma)~22.

Subjects judged to be inappropriate for this study by the investigator or sub-investigator.~26. Concomitant use of rifampicin.
