简要总结
RATIONALE: Exemestane may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. ATN-224 may stop the growth of breast cancer by blocking blood flow to the tumor. It is not yet known whether giving exemestane together with ATN-224 is more effective than giving exemestane alone in treating patients with recurrent or advanced breast cancer.
PURPOSE: This randomized phase II trial is studying the side effects of exemestane given together with or without ATN-224 and to see how well it works in treating postmenopausal women with recurrent or advanced breast cancer.
详细描述
OBJECTIVES:
Primary
- Compare progression-free survival of postmenopausal women with, estrogen receptor- and/or progesterone receptor-positive recurrent or advanced breast cancer treated with exemestane with versus without SOD1 inhibitor ATN-224.
- Establish the safety of SOD1 inhibitor ATN-224 in combination with exemestane in these patients.
Secondary
- Determine the response rate (overall, at 16 and 24 weeks), response duration, and rate of stable disease for ≥ 16 and ≥ 24 weeks in these patients.
- Determine the clinical benefit rate (complete response, partial response, and stable disease) at 16 and 24 weeks in these patients.
- Investigate the time course of suppression of serum ceruloplasmin (Cp, surrogate for copper).
- Investigate serum estradiol and estrone sulphate levels in these patients to assess if SOD1 inhibitor ATN-224 interacts with the aromatase inhibition of exemestane.
