Summary

The purpose of this prospective study is to determine the safety and feasibility of pharmacokinetically (PK) guided dosing of sunitinib in 30 patients.

At day 15 ± 1day, day 29 ± 1day and after 8 weeks ± 1day of sunitinib treatment sunitinib and SU12662 trough levels will be measured. Depending on the sunitinib and SU12662 trough levels (and toxicity) dose adjustments will be made.

Conditions

  • Malignant Solid Tumour

Interventions

DRUG

Sunitinib

Patients will start treatment with a continuous once-daily dose of 37.5 mg sunitinib. After 22 days the first dose modification will be performed based on the total trough levels (TTL) combined for sunitinib plus SU12662 as measured by dried blood spot (DBS) analyses taken at day 15 ± 1day. A second dose modification will be performed after 36 days (7 days after the first dose adjustment) based on the TTL taken at day 29 ± 1day. One treatment cycle is defined as 28 days. After 8 weeks a third analyses for TTL will be performed without further consequences for sunitinib dosing. Patients will be evaluated by CT- or MRI-scans for the response to therapy at week 8, and thereafter every 12 weeks. One blood sample will be harvested for pharmacogenetic analyses.
