First seen Jun 27, 2026 · Last updated Jul 24, 2026 · Updated 3 times

Summary

This study tests whether a new quarterly injection of letrozole delivers the same amount of medicine into the body as the standard daily pill. It involves 120 postmenopausal women who have already completed at least 4-5 years of hormone therapy for early breast cancer. The goal is to see if the injection can offer a more convenient dosing option while maintaining similar drug levels and safety.
