Official title

A Phase II Study of Letrozole in Combination With Bevacizumab in Patients With Estrogen Receptor- and/or Progesterone Receptor-Positive Unresectable Locally Advanced and/or Metastatic (Stage IV) Breast Cancer

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

RATIONALE: Monoclonal antibodies, such as bevacizumab, can block tumor growth in different ways. Some find tumor cells and kill them or carry tumor-killing substances to them. Others interfere with the ability of tumor cells to grow and spread. Bevacizumab may also stop the growth of tumor cells by blocking blood flow to the tumor. Estrogen can cause the growth of breast cancer cells. Hormone therapy using letrozole may fight breast cancer by lowering the amount of estrogen the body makes. Giving bevacizumab together with letrozole may be an effective treatment for locally advanced or metastatic breast cancer. PURPOSE: This phase II trial is studying how well giving bevacizumab together with letrozole works in treating postmenopausal women with locally advanced or metastatic breast cancer that cannot be removed by surgery.
