I. Determine reasonable dose of drugs in treatment combination, including maximum tolerated dose (MTD) and toxicity profiles, via a brief initial "run-in"/dose escalation.
II. Evaluate response, in patients with tumors that demonstrate hormone receptor (HR)-positivity (> 1% on immunohistochemistry [IHC]) and human EGF receptor 2 (HER)-positivity (IHC 3 and/or IHC 2/3 and fluorescence in situ hybridization [FISH] amplification).
I. Correlate activity of combination with genomic and proteomic signatures. II. Evaluate 2 expanded cohorts of patients to include: 1) HR- and HER2-positive breast cancer (n=12) and 2) other HR- and HER2-positive tumors that have demonstrated activity in the dose escalation portion of the study (n=12).
OUTLINE: This is a dose-escalation study of everolimus and trastuzumab.
Patients receive everolimus orally (PO) once daily (QD) and letrozole PO QD. Patients also receive trastuzumab intravenously (IV) over 30-90 minutes once every 3 weeks. Courses repeat every 21 days in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, patients are followed up for at least 30 days.

Experimental: Treatment (everolimus, letrozole, trastuzumab)
Patients receive everolimus PO QD and letrozole PO QD. Patients also receive trastuzumab IV over 30-90 minutes once every 3 weeks. Courses repeat every 21 days in the absence of disease progression or unacceptable toxicity.
Other: Laboratory Biomarker Analysis
- Maximum tolerated dose and/or recommended phase II dose [ Time Frame: 21 days ]Defined as the highest dose at which no more than 1 of 6 patients has had dose-limiting toxicity.
- Clinical benefit rate [ Time Frame: Up to 4 years ]Defined as the percentage of patients with stable disease >= 6 months/partial response/complete response. The point estimate and the 90% exact confidence interval for the clinical benefit rate will be calculated.
