Study Evaluating The Combination Of Neratinib And Capecitabine In Solid Tumors And Breast Cancer

Inclusion Criteria:

• Part 1: confirmed pathologic diagnosis of a solid tumor not curable with available therapies for which neratinib plus capecitabine is a reasonable treatment option.
• Part 2: confirmed histologically and/or cytologically confirmed diagnosis of breast cancer, metastatic or locally advanced.
• Part 2: erbB-2 gene amplified tumor (FISH or CISH) or erbB-2 overexpression (IHC 3+, or IHC2+ with FISH or CISH confirmation), based on local testing, or based on centralized FISH testing prior to day 1.
• Part 2: disease progression on or following at least 1 prior trastuzumab containing treatment regimen (at least 6 weeks) for metastatic or locally advanced disease. (Prior adjuvant trastuzumab is allowed but not required). A 2 week period is required between the last dose of trastuzumab treatment and first dose of the test article.
• Prior treatment with a taxane in the neoadjuvant, adjuvant, locally advanced, and/or metastatic disease treatment setting.
• Parts 1+2: At least 1 measurable lesion as defined by RECIST criteria.
• Parts 1+2: LVEF within institutional range of normal as measured by multi-gated acquisition (MUGA) or echocardiogram (ECHO).

Exclusion Criteria:

• Part 2: prior treatment with capecitabine, lapatinib (20 subjects with prior lapatinib exposure will be enrolled) or any erbB-2 targeted agents except trastuzumab. Treatment with erbB-2 targeted therapy must exceed 2 weeks (14 days) in order to be exclusionary.
• Part 2: prior treatment with anthracyclines with a cumulative dose of doxorubicin of greater than 400 mg/m2, epirubicin dose of greater than 800 mg/m2, or the equivalent dose for other anthracyclines.
• Parts 1+2: Subjects with bone as the only site of disease.
• Parts 1+2: Active uncontrolled or symptomatic central nervous system (CNS) metastases, as indicated by clinical symptoms, cerebral edema, and/or progressive growth. Subjects with a history of CNS metastases or cord compression are allowable if they have been considered definitively treated and are off anticonvulsants and steroids for at least 4 weeks before the first dose of test article.
• Parts 1+2: Any other cancer within 5 years prior to screening with the exception of adequately treated cervical carcinoma in situ, or adequately treated basal or squamous cell carcinoma of the skin.
