Phase II Study Evaluating the Role of Pazopanib in Angiosarcoma

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.

PRIMARY OBJECTIVES:

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.

SECONDARY OBJECTIVES:

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.

OUTLINE:

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.

Inclusion Criteria:

Accountability Act (HIPAA) consent prior to performance of study-specific procedures
or assessments and must be willing to comply with treatment and follow up

- Note: informed consent may be obtained prior to start of the specified screening
window

be greater than 45 years of age OR have had documented evidence of menopause based on
FSH and estradiol concentrations prior to initiation of HRT

- Childbearing potential, including any female who has had a negative serum pregnancy
test within 2 weeks prior to the first dose of study treatment and for 3 months after
the completion of treatment, preferably as close to the first dose as possible, and
agrees to use adequate contraception; acceptable contraceptive methods, when used
consistently and in accordance with both the product label and the instructions of
the physician, are as follow:

- Complete abstinence from sexual intercourse for 14 days before exposure to
investigational product, through the dosing period, and for at least 21 days
after the last dose of investigational product

- Oral contraceptive, either combined or progestogen alone

- Injectable progestogen

- Implants of levonorgestrel

- Estrogenic vaginal ring

- Percutaneous contraceptive patches

- Intrauterine device (IUD) or intrauterine system (IUS) with a documented failure
rate of less than 1% per year

for that subject

- Double barrier method: condom and an occlusive cap (diaphragm or cervical/vault
caps) with a vaginal spermicidal agent (foam/gel/film/cream/suppository)

- Female subjects who are lactating must discontinue nursing prior to the first dose of
study drug and refrain from nursing throughout the treatment period and for 14 days
