Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this study is to examine if a short-term treatment with pazopanib, an oral drug inhibiting the growth of blood vessel, can reduce the metabolism of soft-tissue sarcomas and thus facilitate their resection when given prior to surgery. Moreover, the study assesses the prognostic and predictive value of several new biomarkers (endothelial progenitor cells, soluble vascular epithelial growth factor),

2. Age ≥ 18 years or legal age of consent if different from 18 years.
3. Non-metastatic primary tumor or locoregional recurrence of histologically confirmed high-risk (G2/3, diameter ≥5 cm) soft tissue sarcoma (STS) of any location (extremities, girdle, trunk, retroperitoneum); or metachronous solitary metastasis of STS for which surgical resection is planned according to the individual choice of the multidisciplinary treatment team (no grade or size restrictions apply for metastasis).
4. Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1.
5. Measurable disease according to RECIST 1.1
6. Resectable and solitary tumor, as assessed by the investigator based on staging exams (CT scan of the chest, CT or MRI of the abdomen, MRI of the limb in case of extremity STS).
7. Adequate organ system function
8. Women of childbearing potential must have a negative serum pregnancy test within 14 days of first dose of study treatment and agree to use effective contraception, during the study and until after surgery has been performed.
9. Female subjects who are lactating should discontinue nursing prior to the first dose of study drug and should refrain from nursing throughout the treatment period and for 14 days following the last dose of study drug.
