Official title
A Randomized Window of Opportunity Study of Preoperative Letrozole and Simvastatin Versus Letrozole Alone in Stage I-III Hormone Receptor Positive, HER2 Negative Breast Cancer
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
This early phase I trial tests whether letrozole with simvastatin works better than letrozole alone to stop tumor cell proliferation in patients with stage I-III hormone receptor positive, HER2 negative invasive breast cancer. Letrozole and simvastatin may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. The addition of simvastatin to letrozole may be more effective at stopping the growth of cancer cells than letrozole alone.
