Pre-Surgical Trial of the Combination of Metformin and Atorvastatin in Newly Diagnosed Operable Breast Cancer

Overview[ - collapse ][ - ]

Purpose The purpose of this study is to determine the effects of combining metformin and atorvastatin treatment in patients with newly diagnosed breast cancer during the interval between breast biopsy and surgery. Metformin is a medication used to treat patients with diabetes. It has been shown to have anti-tumor properties in breast cancer. Atorvastatin is widely used for the treatment of elevated cholesterol and has also shown to have anti-tumor properties in breast cancer. Both have safely been used in patients without diabetes or elevated cholesterol. This study will assess the impact of combined metformin and atorvastatin on breast tumor tissue markers as well as blood levels, including cholesterol and insulin. Both medications will be given for two weeks prior to your scheduled breast surgery.

Brief Summary
The purpose of this study is to determine the effects of combining metformin and
atorvastatin treatment in patients with newly diagnosed breast cancer during the interval
between breast biopsy and surgery. Metformin is a medication used to treat patients with
diabetes. It has been shown to have anti-tumor properties in breast cancer. Atorvastatin is
widely used for the treatment of elevated cholesterol and has also shown to have anti-tumor
properties in breast cancer. Both have safely been used in patients without diabetes or
elevated cholesterol. This study will assess the impact of combined metformin and
atorvastatin on breast tumor tissue markers as well as blood levels, including cholesterol
and insulin. Both medications will be given for two weeks prior to your scheduled breast
surgery.
Detailed Description
Utilizing a pre-surgical model, we plan to conduct a pilot study of 40 women with newly
diagnosed invasive breast cancer or ductal carcinoma in-situ (DCIS) who will receive oral
metformin and atorvastatin daily for at least two weeks, in the interval between diagnostic
breast biopsy and definitive breast surgery. In this pre-surgical trial, patients will
receive metformin and atorvastatin at bedtime. Women with histologically-confirmed invasive
breast cancer or DCIS will be recruited by the medical oncologist and will start the dual
therapy at least two weeks prior to their scheduled surgery.

The primary objective of this study is to evaluate changes in tissue levels of the
proliferation marker Ki-67. These will be compared to a) historical control group of
metformin treated patients and b) historical control matched by age, body mass index, and
tumor stage who did not receive metformin or statin. Secondary endpoints include assessment
of changes in protein expression of AMPK/mTOR signaling; modulation of apoptosis markers
such as bax, bid, and various caspase levels; and changes in fasting serum markers of the
insulin growth factor pathway such as insulin, glucose, and lipids. The goal is to
determine if dual combination treatment with metformin plus atorvastatin significantly
impacts tumor-based markers, such as proliferation, and blood-based biomarkers.
