Atorvastatin in Treating Patients With Stage IIb-III Triple Negative Breast Cancer Who Did Not Achieve a Pathologic Complete Response After Receiving Neoadjuvant Chemotherapy

Summary

This phase II trial studies how well atorvastatin works in treating patients with stages IIb-III triple negative breast cancer who did not achieve a pathologic complete response to neoadjuvant chemotherapy. Pathologic complete response is the lack of all signs of cancer in tissue samples removed during surgery after upfront chemotherapy. Atorvastatin is used for the treatment of high cholesterol and may reduce the risk of triple negative breast cancer from coming back. Triple-negative breast cancer is a type of breast malignancy that is comprised of cancer cells that do not have estrogen receptors, progesterone receptors, or large amounts of HER2/neu protein. Patients with TNBC do not have established systemic therapies such as anti-estrogens or HER2-targeting agents to reduce recurrence after surgery, and residual cancer found at surgery is associated with higher relapse rate.

Interventions

DRUG

Atorvastatin

Patients will receive Atorvastatin per ASCVD guidelines dosed as either a moderate intensity (20mg/day) or high intensity statin (80mg/day). Tablets are available in either 20mg or 80mg and will be dispensed as per standard of care for up to 24 months as part of the study. Patients may also receive capecitabine concurrently with Atorvastatin per physician discretion as standard of care. Standard of care dosing of Capecitabine is a 21 day cycle consisting 14 days on and 7 days off. The starting dosing will be per physician discretion, but may be up to 2500mg/m2 per day.

DRUG

Capecitabine

Patients not eligible to receive atorvastatin in group II will be enrolled into non-statin observation group with/without capecitabine treatment. Capecitabine administration will be dosed as per standard of care. Standard of care dosing of Capecitabine is a 21 day cycle consisting 14 days on and 7 days off. The starting dosing will be per physician discretion, but may be up to 2500mg/m2 per day.
