However, carcinoma in situ that is determined to be cured by local treatment or lesions equivalent to mucosal carcinoma are not included in active multiple malignancies.)

10. Have an uncontrolled complication.

11. Complicated by mental deficits or have a history of mental deficits. However, patients who are able to comply with the study protocol can be included at the discretion of a physician.

12. Complicated by varicella.

13. Received any previous treatment with DSP-2033 or other CDK inhibitors.

14. Received any investigational product or post-marketing clinical study drug within 3 months (90 days) prior to entry.

15. Pregnant or lactating women*)

*) If a lactating woman agrees to discontinue breast feeding between acquisition of informed consent and 6 months (180 days) after the final dose, she could be included in the study.
