incompatible with the protocol

2. Active infectious disease

3. Viral hepatitis, HIV infection

4. Clinical evidence of active brain metastasis or leptomeningeal disease during the

5. Second malignancy currently requiring active therapy (except for hormonal /
antihormonal treatment e.g. in prostate or breast cancer)

6. Absolute neutrophil count less than 1,500/mm3

7. Platelet count less than 100,000/mm3

8. Total bilirubin greater than 1.5 mg/dL (> 26 µmol/L, SI unit equivalent)

10. Serum creatinine greater than 2x upper limit of normal (ULN)

11. QTcF prolongation > 470 ms or QT prolongation deemed clinically relevant by the
investigator (e.g., congenital long QT syndrome).The QTcF will be calculated as the
mean of the 3 ECGs taken at screening

12. Female patients with childbearing potential and unwilling to use a medically
acceptable method of contraception during the trial and for at least six months after

weeks prior to start of therapy or concomitantly with this trial. This restriction
does not apply to steroids, bisphosphonates hormonal / antihormonal treatment (e.g.
in prostate or breast cancer).

(other then study drug), ketoconazole, nefazodone, nelfinavir, ritonavir,
saquinavir, telithromycin

2. CYP 3A4 inducers: carbamazepine, rifampicin

3. P-gp inhibitors: cyclosporine, erythromycin, itraconazole (other then study
drug), ketoconazole, quinidine, phenobarbital salt with quinidine, ritonavir,
valspodar, verapamil

4. P-gp inducers: hypericum perforatum, rifampicin
