Patients must have adequate hematological, renal and liver functions as defined by laboratory values below performed within 14 days prior to study inclusion:

• absolute neutrophil count (ANC) > 1.5 x 109/l
• platelet count > 100 x 109/l

In addition:

• Patients should not suffer from frequent vomiting or medical conditions which could interfere with oral medication intake.
• Negative pregnancy test of women of childbearing potential performed within 7 days prior to the start of treatment.
• Women of childbearing potential must agree to use an effective method of contraception (Pearl-Index < 1, e.g. hormonal contraception including the combined oral contraceptive pill, the transdermal patch, and the contraceptive vaginal ring, intrauterine devices or sterilization) during treatment and for at least 6 months thereafter.
• Men must agree to use an effective method of contraception during treatment and for at least 6 months thereafter.
