This is a Phase I research study designed to determine the maximum tolerated dose (MTD) of cisplatin, temsirolimus, and erlotinib in combination for treatment in triple negative breast cancer (TNBC) patients.
The stratification of breast cancer patients for treatment targeting either the estrogen receptor (ER) or human epidermal growth factor receptor 2 (HER2) receptor based upon the measurement of ER/progesterone receptor (PR) and HER2 in tumor tissue has changed the treatment of breast cancer. However, the success of this stratification has resulted in the recognition that no effective rational treatment exists for patients that lack these receptors. The term "triple negative breast cancer" (TNBC) has been used to define a class of unresponsive patients, which is based upon their lack of the hormone receptors for estrogen and progesterone and the HER2 oncogene. TNBC represents a form of breast cancer for which no targeted therapy is known. Thus, identifying and understanding the signaling pathways and receptors that contribute to triple negative tumor growth is of high priority in order to develop therapies analogous to the ones that have already been developed for HER2 and ER. Available data from Phase I trials have demonstrated that mTOR inhibitors and EGFR inhibitors have been safely given together at doses shown to inhibit their respective targets and Phase II studies are ongoing in advanced renal cell, pancreatic, glioma, and breast (not specifically TNBC) cancers. The rationale for adding cisplatin to erlotinib and an mTOR inhibitor are many. Cisplatin is a known active cytotoxic against breast cancer. It has non overlapping toxicity with erlotinib and TORC1 mTOR inhibitors and patients are unlikely to have been previously treated with cisplatin. Therefore, as a cytotoxic DNA damaging agent, cisplatin could trigger cell death in a cell whose survival pathways are effectively inhibited by mTOR inhibition and erlotinib.

Temsirolimus will be administered intravenously weekly on days one and eight of a three week cycle. Temsirolimus will not be given on week three (usually dosed weekly) for increased tolerability given its possible plasma accumulation during week three. Temsirolimus will be given second over a 30 minute infusion during posthydration. Dose escalation will follow the standard 3 by 3 design with three set dosing levels. Dose Level 1: Temsirolimus 15mg Dose Level 2: Temsirolimus 15mg Dose Level 3: Temsirolimus 25mg
Cisplatin at 30mg/m2 will be administered intravenously weekly on days one and eight of a three week cycle. Cisplatin will be given first over a 30 minute infusion with prehydration.
Erlotinib will be taken by mouth daily starting at 100mg. On days of cisplatin and temsirolimus infusions, erlotinib should be taken at least two hours after the beginning of the temsirolimus infusion. Dose escalation will follow the standard 3 by 3 design with three set dosing levels. Dose Level 1: Erlotinib 100mg Dose Level 2: Erlotinib 150mg Dose Level 3: Erlotinib 150mg
