Summary

The lay summary the sponsor registered on ClinicalTrials.gov.

Fulvestrant has proven effective in the treatment of hormone receptor positive metastatic breast cancer. The dose used in studies so far has been well tolerated and may be too low for optimal effectiveness. In this study, a higher dose will be used to see whether an improved outcome will result.
