Summary

The purpose of this research project is to study the effect of a research (investigational) drug, MK-0752 combined with either tamoxifen or letrozole on breast cancer cells.

Tamoxifen and letrozole are standard hormone treatments used to treat breast cancers that are positive for the estrogen receptor. However, over time the breast cancer cells can become resistant to tamoxifen and letrozole. MK-0752 is in a class of drugs called gamma secretase inhibitors. Gamma secretase inhibitors may play a role in reversing the resistance to drugs such as tamoxifen and letrozole.

MK-0752

Women who are post menopausal will receive letrozole 2.5 mg by mouth one time per day for 24 days. Women who are pre menopausal, or who have a contraindication to letrozole will receive tamoxifen 20 mg orally one time per day for a period of 24 days. Starting on day 15 of this 24 day period all patients will receive the oral gamma-secretase inhibitor drug MK-0752 at a dose of 350 mg for three days on, then off four days, then three days on, for a total of 6 doses over a period of 10 days.
