Brief Summary:
This phase II trial studies how well pazopanib hydrochloride works in treating patients with advanced angiosarcoma. Pazopanib hydrochloride may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.

Condition or disease Intervention/treatment Phase
Adult Angiosarcoma Recurrent Adult Soft Tissue Sarcoma Stage III Adult Soft Tissue Sarcoma Stage IV Adult Soft Tissue Sarcoma Drug: pazopanib hydrochloride Other: laboratory biomarker analysis Procedure: positron emission tomography Procedure: computed tomography Radiation: fludeoxyglucose F 18 Phase 2

Detailed Description:


I. To determine the progression free survival (PFS) at 3 months and response rate defined as complete response (CR) and partial response (PR) in angiosarcoma patients treated with pazopanib.


I. To assess overall survival of patients treated with pazopanib. II. To gather more safety data for pazopanib in this patient population. III. To explore the ability of [F-18] fludeoxyglucose (FDG) (positron emission tomography [PET])/computed tomography (CT) imaging to assess response.


Patients receive pazopanib hydrochloride orally (PO) once daily (QD). Courses repeat every 21 days in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up every 3 months for 2 years.
