Therapeutic Angiotensin-(1-7) in Treating Patients With Metastatic Sarcoma That Cannot Be Removed By Surgery
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.

- Antitumor Activity as Assessed by Number of Patients Showing an Objective Tumor Response [ Time Frame: Approximately 1 year ] [ Designated as safety issue: No ]'Activity' will be operationalized using objective tumor response, which will be estimated as the proportion of partial and complete responders (according to Response Evaluation Criteria in Solid Tumors [RECIST] criteria) among all evaluable patients.
- Number of Participants Who Experienced Adverse Events as Assessed by Common Terminology Criteria for Adverse Events (CTCAE) Version 3.0 [ Time Frame: Approximately 1 year ] [ Designated as safety issue: Yes ]See the adverse event tables for specifics.
- Time to Disease Progression [ Time Frame: Approximately 5 years ] [ Designated as safety issue: No ]
- Overall Survival [ Time Frame: Approximately 5 years ] [ Designated as safety issue: No ]
- Plasma Levels of Angiogenic Peptides Including Placental Growth Factor (PlGF) [ Time Frame: Day 1 ] [ Designated as safety issue: No ]
- Plasma Levels of Angiogenic Peptides Including PIGF [ Time Frame: Day 22 ] [ Designated as safety issue: No ]
|Study Start Date:||October 2009|
|Primary Completion Date:||January 2013 (Final data collection date for primary outcome measure)|
Experimental: Treatment (antiangiogenesis therapy)
Patients receive therapeutic angiotensin-(1-7) SC once daily in the absence of disease progression or unacceptable toxicity.
Drug: therapeutic angiotensin-(1-7)
Other Names:Other: laboratory biomarker analysis
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.
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).
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.
