Letrozole with or without a cholesterol drug for early breast cancer
Treatments studied
Part of Cancer clinical trials.
This early-phase study tests whether adding simvastatin to letrozole can improve outcomes in people with stage I–III breast cancer that grows with hormone signals (hormone receptor positive) and does not have HER2. It looks mainly at whether the approach is safe and useful for this specific breast cancer type.
Summary written for real people, not researchers, by Clin2.
Who can take part
- Be 18 years or older and post-menopausal
- Have biopsy-proven invasive breast cancer that is hormone receptor positive (ER and/or PR) and HER2 negative
- Have stage I–III breast cancer with a tumor at least 5 mm on imaging
- Have tumor Ki-67 level of 10% or higher (a lab marker of how fast cells are growing)
- Be well enough to do usual activities (ECOG performance status 0–2) and agree to frequent visits and study tests
- You must not have had chemotherapy, immunotherapy, or hormone (endocrine) treatment within the last 3 months, and you must not have used a statin or similar cholesterol drugs (statins, fibrates, or ezetimibe) within the last 3 months

This trial tests whether skipping chemotherapy and using only hormone therapy with a drug called ribociclib works as well as chemotherapy followed by hormone therapy with ribociclib for certain early breast cancers that have a low risk of coming back.
This trial tests whether taking letrozole before surgery can help shrink tumors in postmenopausal women with a specific type of early-stage breast cancer that is hormone-receptor-positive, HER2-negative, and has spread to lymph nodes.
This trial tests whether a cholesterol medicine (a statin) can lower the risk of heart damage in people receiving HER2-targeted breast cancer therapy. If you qualify, you may be given a statin and followed with heart tests and blood work to watch for safety and benefit.
This Phase 3 study tests whether taking atorvastatin (a cholesterol-lowering medicine) can improve outcomes for women with estrogen-receptor–positive breast cancer. It may help by affecting cancer-related pathways and reducing risk of recurrence or progression.
This study tests a new version of the hormone therapy letrozole (Letrozole SIE) compared to the standard letrozole (Femara®), both given together with a targeted therapy called ribociclib. It is for postmenopausal women with HR-positive, HER2-negative breast cancer that has spread to other parts of the body and has not yet been treated for advanced disease.
This Phase 2 study compares a combination medicine (lenvatinib plus letrozole) against fulvestrant to treat metastatic estrogen-receptor positive, HER2-negative breast cancer after the cancer has grown despite hormone therapy plus a CDK4/6 inhibitor. It may help by finding a more effective treatment option after your first lines have stopped working.
