Brief summary:
This phase II trial studies how well therapeutic angiotensin-(1-7) works as second-line therapy or third-line therapy in treating patients with metastatic sarcoma that cannot be removed by surgery. Therapeutic angiotensin-(1-7) may stop the growth of sarcoma by blocking blood flow to the tumor.

Detailed description:
PRIMARY OBJECTIVES:

I. To evaluate the response rate of chemotherapy-refractory sarcomas to 20 mg per day of single-agent Ang(Angiotensin)-(1-7) or 10 mg per day of single-agent Ang-(1-7) if excessive toxicity is observed at the 20 mg dose.

II. To evaluate toxicities associated with single-agent Ang-(1-7) when given to patients with chemotherapy-refractory sarcomas.

SECONDARY OBJECTIVES:

I. To assess time to progression (TTP) and overall survival (OS) in patients treated with Ang-(1-7).

II. To evaluate accumulation of Ang-(1-7) after 21 days of continuous treatment and quantify changes in plasma levels of angiogenic peptides including placental growth factor (PlGF).

OUTLINE:

Patients receive therapeutic angiotensin-(1-7) subcutaneously (SC) once daily in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed every 3 months for 2 years, every 6 months for 3 years, and then annually thereafter.

Arms:
arm 1: Patients receive therapeutic angiotensin-(1-7) SC once daily in the absence of disease progression or unacceptable toxicity.

Interventions: intervention 1: therapeutic angiotensin-(1-7) intervention 2: laboratory biomarker analysis
Intervention descriptions: intervention 1: Given SC intervention 2: Correlative study
