Details and patient eligibility

About

This is an open, monocentric, pilot study to determine the metabolic activity (glucose-uptake) in vivo during monotherapy with pazopanib in comparison to combination therapy with pazopanib plus paclitaxel and to investigate the transcriptional profile of cutaneous melanoma metastasis before and during the therapy (pazopanib vs. pazopanib plus paclitaxel) in subjects with unresectable Stage III or Stage IV melanoma who have not received prior cytotoxic chemotherapy.

Primary Objective:

Evaluation of metabolic activity in vivo

Secondary Objective:

Determination of changes in gene expression profiling Evaluation of the antitumor activity of the combination in terms of progression free survival (PFS). Changes in S100 and LDH during therapy at the same time points as FDG-PET/CT (a combined serum measurement of S100 and LDH)
