Evaluation of Votrient in Angiosarcoma

Open-label phase II trial investigating the efficacy and safety of the investigational combination of pazopanib and paclitaxel.

Open-label phase II trial investigating the efficacy and safety of the investigational combination of pazopanib and paclitaxel.This multi-center, open-label, prospective, single arm phase II study was designed to evaluate the clinical efficacy and safety of the experimental combination of pazopanib with paclitaxel in the treatment of patients with advanced or metastatic angiosarcoma.The safety evaluations (physical examination, laboratory checks as defined in protocol, toxicity/adverse event assessment according Eastern Cooperative Oncology Group version 4.0) are scheduled every cycle at day 1, 8, 15 and 29 (= day 1 of the next cycle).

Eligibility Criteria:
Inclusion Criteria:

* All sexually active male patients must agree to use adequate methods of birth control (see protocol) throughout the study and for 30 days after the last dose of study drug.

Exclusion Criteria:

* Poorly controlled hypertension (see protocol)
* Evidence of active bleeding or bleeding diathesis
* Known endobronchial lesions and/or lesions infiltrating major pulmonary vessels
* Uncontrolled seizures, disorders of the CNS or psychiatric disorders which may put patient safety at risk, prevent giving informed consent or impact the patient's compliance with the use of study medication
