Summary

The lay summary the sponsor registered on ClinicalTrials.gov.

A short pre-surgical non-therapeutic trial involving postmenopausal women with newly diagnosed eR+, HeR2-negative operable breast cancers. After undergoing a core needle biopsy for tissue acquisition, study participants will take a 7- to 30-day (1-4 weeks) course of letrozole in accordance with standard of care. They will then undergo definitive surgical resection of their primary tumor (mastectomy vs lumpectomy) as per standard of care guidelines.
