Inclusion Criteria for all subjects (HER2-Amplified and Triple-negative)

• Patients with a diagnosis of invasive adenocarcinoma of the breast confirmed by histology or cytology at MSKCC.
• Metastatic disease that is or has been pathologically documented.
• At least one measurable metastatic lesion according to RECIST 1.1 criteria. Ascites, pleural effusions, and bone metastases are not considered measurable. Minimum indicator lesion size ≥ 10 mm by helical CT or ≥ 20 mm by conventional techniques.
• Pathological nodes must be ≥ 15 mm by the short axis to be considered measurable.
• Age ≥ 18, as no dosing or adverse event data are currently available on the use of neratinib or temsirolimus in patients <18 years of age, children are excluded from this study.
• Patients must be willing to discontinue sex hormonal therapy, e.g., birth control pills, hormonal replacement therapy, prior to enrollment. Women of childbearing potential must consent to effective contraception while on treatment and for a period thereafter.
• Negative serum human chorionic gonadotropin pregnancy test for premenopausal women of reproductive capacity and for women less than 12 months after menopause.
• Asymptomatic, central nervous system metastases are permitted if patients remain clinically stable after discontinuation of steroids and anticonvulsants for 3 months.
• Eastern Cooperative Oncology Group (ECOG) performance status score of ≤2.
• Patients must have normal organ and marrow function: aspartate aminotransferase (AST), alanine aminotransferase (ALT) ≤2.5x institutional upper limit of normal except for patients with liver metastases. For patients with liver metastases, AST/ALT/Alkaline phosphatase ≤5.0x institutional upper limit of normal. Total bilirubin within institutional limits except for patients with liver metastases. For patients with liver metastases, total bilirubin ≤1.5x institutional upper limit of normal. Creatinine clearance within normal limits or ≥ 60 mL/min, prothrombin time and partial thromboplastin time ≤1.5x institutional upper limit of normal except for patients on Coumadin or low molecular weight heparin, leukocytes ≥3,000/μl, absolute neutrophil count ≥1,000/μl, and platelets ≥75,000/μl
• Able to swallow and retain oral medication.

The following criteria were removed for all patients in Protocol Amendment 10, and are only applicable to first 34 HER2+ patients in Phase 2 who are not subject to dose-escalation of temsirolimus:

• Able and willing to consent for biopsy of metastatic breast cancer prior to treatment. Consent to preservation of frozen and fixed samples of tumor cores for evaluation. (HER2-amplified patients who have previously provided samples of metastatic breast cancer as part of institutional review board #06-163 will be exempt)
• Consent to evaluation of primary tumor biopsy specimen.

Exclusion Criteria:

• Potential subjects will be excluded from enrollment into this study if they meet any of the following criteria:
• Patients receiving any concurrent anticancer therapy or investigational agents with the intention of treating breast cancer.
• History of allergic reactions attributed to compounds of similar chemical or biologic composition to neratinib or temsirolimus.
• Unable to consent to biopsy of metastatic disease or for whom a biopsy would be medically unsafe.
• Women who are pregnant or breast feeding.
• Life expectancy <3 months.
• Completion of previous chemotherapy regimen <3 weeks prior to the start of study treatment. Prior hormonal therapy must be discontinued prior to treatment start. Biologic therapy with bevacizumab for the treatment of metastatic disease must be discontinued ≥3 weeks from the start of protocol treatment.
• Concurrent radiotherapy is not permitted for disease progression on treatment on protocol, but might be allowed for pre-existing non-target lesions with approval from the principal investigator of the trial.
• Concurrent medical conditions which may increase the risk of toxicity, including ongoing or active infection, history of significant bleeding disorder unrelated to cancer (congenital bleeding disorders, acquired bleeding disorders within one year), HIV-positive or active hepatitis.
• History of clinically significant or uncontrolled cardiac disease, including congestive heart failure, angina, myocardial infarction, arrhythmia, and left ventricular ejection fraction less than 50% measured by a multigated blood pool imaging of the heart (MUGA scan) or an echocardiogram (ECHO).
• QT corrected interval > 0.47 seconds.
• Patients with GI tract disease resulting in an inability to take oral medication, malabsorption syndrome, a requirement for IV alimentation, prior surgical procedures affecting absorption, or uncontrolled inflammatory GI disease.
• History of an invasive second primary malignancy diagnosed within the previous 3 years, except for stage I endometrial or cervical carcinoma or prostate carcinoma treated surgically, and non-melanoma skin cancer.
• History of uncontrolled seizures, central nervous system disorders or psychiatric disability judged by the investigator to be clinically significant, precluding informed consent, or interfering with compliance of oral drug intake.
• Unwillingness to give written informed consent, unwillingness to participate, or inability to comply with the protocol for the duration of the study. Willingness and ability to comply with scheduled visits, treatment plan, laboratory tests and other study procedures are necessary to participation in this clinical trial.
