•7.Absolute neutrophil count >1,500 cells/mm3; PLTs >90,000/ mm3
•8.Negative urine or serum pregnancy test (for women of childbearing potential) documented within the 24-hour period prior to the first dose of the drug. Additionally, all fertile male patients with female partners of childbearing age and females must be using two reliable forms of effective contraception (combined) during the study and for 3 months after treatment completion.
