Brief Summary:
Extended phase 1 trial of combined metformin and erlotinib in advanced triple negative breast cancer patients. The goals of the study are to establish the maximum tolerated combined dosing of erlotinib and metformin as well as deciding if there is a potential clinical utility of the combination in treating patients with triple negative breast cancer.

Condition or disease Intervention/treatment Phase
Breast Cancer Drug: Metformin Drug: Erlotinib Phase 1

Detailed Description:
Breast cancer has several different subtypes based upon measurement of expression of proteins found on the surface of the cancer cells. Cancers that lack expression of three of these proteins, namely the estrogen receptor, progesterone receptor, and human epidermal growth factor receptor 2 (HER2), are termed triple negative. By studying the molecular attributes of breast cancer cells from a large group of breast cancer patients, a profile of markers enriched in triple negative breast cancers (TNBC) was discovered. This profile includes loss of expression of the protein, Phosphatase and Tensin homolog (PTEN), increased expression of the protein, epidermal growth factor receptor (EGFR), and disruption of the cells ability to repair DNA. These alterations also allow the tumor to thrive and likely evade treatment. Observation has been made that the drug combination of metformin and erlotinib can inhibit triple negative cells with these alterations. A clinical trial will be conducted to test the ability of patients to tolerate the treatment (Phase I trial). This trial will be available to triple negative breast cancer patients with metastatic disease. Other goals of the study will be to confirm that the drugs are working properly and whether or not there are enough responses to the treatment to warrant additional studies. If the treatment proves to be effective, even if only in a subset of triple negative patients, future studies will focus on validating biomarkers that can identify patients that will respond to the drug combination, as well as discovering how cells become resistant to the treatment. The research has the potential to advance a new effective treatment for a highly lethal disease and thus could prolong patient survivals while maintaining a high quality of life.

Arm Intervention/treatment
Experimental: Erlotinib + Metformin
This is a single arm phase 1 study. All patients will receive erlotinib and metformin.
Drug: Metformin
Due to frequent GI upset in patients starting metformin the dose will be titrated up to the assigned dose level. The first metformin dose level will be 850 mg twice daily and be escalated to its maximum FDA approved dose of 850 mg three times daily. Dose escalation will follow the standard 3 + 3 design. Dose limiting toxicities will be determined during the first 5 weeks of therapy.
Other Name: Glucophage

Drug: Erlotinib
Erlotinib dosing will start and remain at 150 mg daily.
Other Name: Tarceva

Primary Outcome Measures :
  1. The maximum tolerated dose of metformin in combination with a fixed dose of 150 mg erlotinib daily [ Time Frame: Up to 5 weeks ]
    The highest dose of a treatment that does not cause unacceptable side effects.
