Inclusion Criteria:
- Age >18
- A malignancy treated with single agent sunitinib
- ECOG 0, 1 or 2 at time of study accruement
- Any stable dose of therapy with sunitinib (defined as no dose change within 3 weeks prior to blood collection for pharmacokinetics)
- Adequate liver and renal function defined as serum bilirubin concentration less than 2 x ULN, AST and ALT less than 2.5 x ULN, serum creatinine concentration less than 2 x ULN
- No known primary liver disease and no other severe or uncontrolled concurrent medical condition within the first 3 months of treatment with sunitinib.
- Patients who have participated on other clinical studies of sunitinib will be suitable for this study.
- Signed informed consent
- Patients must not have Class ¾ cardiac problems as defined by the New York Heart Association criteria or any other severe or uncontrolled concurrent medical disease.
- Patients must not be pregnant or nursing and must be using an effective contraception method
Exclusion Criteria:

To observe the correlation between ABCB1 polymorphisms in Exons 13, 22 and 27 and the clearance of sunitinib at steady state.
Zeitfenster: 4 weeks
|
A blood sample will be drawn on day 1 of any treatment cycle and at steady state of the same cycle (between Day 21 and 28 inclusive)

To determine whether ABCB1 genotype correlates with toxicity-adjusted dose of sunitinib
Zeitfenster: 3 months
|
Toxicity adjustments will be collected within the first 3 months and correlated with the ABCB1 genotypes.

|
To determine the pharmacokinetics at steady state of the sunitinib treatment.
Zeitfenster: 4 weeks
|
A blood sample will be drawn on day 1 of treatment cycle and at steady state of the same cycle (between Day 21 and 28 inclusive).
The time of the blood collection are at day1 and in the 4th week: pre-drug administration then at 4 hours, 8 hours and 24 hours after drug intake.
|
4 weeks
|
|
To examine correlations between ABCB1 genotype and toxicity grade according to CTC criteria.
Zeitfenster: 3 months
|
The toxicity data of the first 3 months of treatment will be collected.
|
3 months
|
|
To examine the correlation between genotype haplotype of other drug elimination genes, such as organic anion transporter proteins (OATP) and other biliary efflux proteins such as MRP2, BCRP with sunitinib clearance and toxicity adjusted dose.
Zeitfenster: 3 months
|
Investigations of drugelimination and clearance taken with in the first 4 weeks of the study will be collected as well as the toxicity data and dose adjustments within the first 3 month of treatment.
|
3 months

|
Correlation of drug elimination phenotype test (sestamibi liver scan and Midazolam clearance) with sunitinib clearance
Zeitfenster: 4 weeks
|
sestamibi liver scan and midazolam clearance test will be performed pre-treatment and at steady state (sometime between day 21-28)of study participation.
