7. Patients whose latest laboratory data meet the below criteria within 7 days before
registration. If the date of the laboratory tests at the time of registration is not
within 7 days before the first dose of the investigational product, testing must be
repeated within 7 days before the first dose of the investigational product, and these
latest laboratory tests must meet the following criteria. Of note, laboratory data
will not be valid if the patient has received a granulocyte colony-stimulating factor
(G-CSF) or blood transfusion within 14 days before testing.
- White blood cells =2,000/mm3 and neutrophils =1,500/mm3
- Platelets =100,000/mm3
- Hemoglobin =9.0 g/dL
- AST (GOT) and ALT (GPT) =3.0-fold the upper limit of normal (ULN) of the study
site (or =5.0-fold the ULN of the study site in patients with liver metastases)
- Total bilirubin =1.5-fold the ULN of the study site
- Creatinine =1.5-fold the ULN of the study site or creatinine clearance (either
the measured or estimated value using the Cockcroft-Gault equation) >45 mL/min
8. Women of childbearing potential (including women with chemical menopause or no
menstruation for other medical reasons) #1 must agree to use contraception#2 from the
time of informed consent until 5 months or more after the last dose of the
investigational product. Also, women must agree not to breastfeed from the time of

menstruation who are not postmenopausal and have not been surgically sterilized
(e.g., hysterectomy, bilateral tubal ligation, bilateral oophorectomy).
Postmenopause is defined as amenorrhea for =12 consecutive months without
specific reasons. Women using oral contraceptives, intrauterine devices, or
mechanical contraception such as contraceptive barriers are regarded as having
childbearing potential.
- The subject must consent to use any two of the following methods of
contraception: vasectomy or condom for patients who are male or female subject's
partner and tubal ligation, contraceptive diaphragm, intrauterine device,
spermicide, or oral contraceptive for patients who are female or male subject's
partner.

basal cell carcinoma, stage I squamous cell carcinoma, carcinoma in situ, intramucosal
carcinoma, or superficial bladder cancer, or any other cancer that has not recurred
for at least 5 years)
2. Patients with residual adverse effects of prior therapy or effects of surgery that

11. Patients with a history of uncontrollable or significant cardiovascular disease
meeting any of the following criteria:
- Myocardial infarction within 180 days before registration
- Uncontrollable angina pectoris within 180 days before registration
- New York Heart Association (NYHA) Class III or IV congestive heart failure
- Uncontrollable hypertension despite appropriate treatment (e.g., systolic blood
pressure =150 mmHg or diastolic blood pressure = 90 mmHg lasting 24 hours or
more)
- Arrhythmia requiring treatment
12. Patients receiving or requiring anticoagulant therapy for a disease. Patients
receiving antiplatelet therapy including low-dose aspirin may be enrolled.
13. Patients with uncontrollable diabetes mellitus
14. Patients with systemic infections requiring treatment

registration

days before registration

diagnostic use of radiopharmaceuticals) within 56 days before registration
22. Patients with a positive test result for any of the following: HIV-1 antibody, HIV-2
antibody, HTLV-1 antibody, HBs antigen, or HCV antibody (except if HCV-RNA negative)
23. Patients with a negative HBs antigen test but a positive test result for either HBs
