What this study is testing
What is US-sourced oral Femara® + Letrozole SIE?
US-sourced oral Femara® + Letrozole SIE is an investigational medicine, given as an once-daily pill taken by mouth, being studied as a potential treatment for hormone receptor positive early breast cancer.

- What it's testing
- The study aims to compare the amount of the drug letrozole that gets into the bloodstream after multiple doses of the quarterly injection Letrozole SIE, versus multiple doses of the standard oral daily tablet of letrozole (Femara®), in women who have gone through menopause and have received treatment for hormone receptor-positive early breast cancer. Participants must have completed at least five years of hormone therapy with at least two of those years with letrozole before starting their participation in the study.
