BMS-599626 in Treating Patients With Metastatic Solid Tumors

DISEASE CHARACTERISTICS:

* Histologically or cytologically confirmed primary solid (i.e., non-hematologic) tumor

  * Radiographic or tissue confirmation of metastatic disease

    * Locally advanced disease allowed if no surgical or local therapeutic treatment exists
* HER2/neu overexpression (1+, 2+, or 3 +) by immunohistochemistry

  * Tumors with HER2 gene amplification by fluorescence in situ hybridization analysis allowed
* Tumor paraffin tissue block OR 20-30 unstained slides from tumor tissue block must be available for biomarker and predictive marker analyses
* Disease progression during or after standard therapy OR no standard therapy exists
* Measurable or non-measurable disease

  * Measurable disease is required for the expanded cohort treated at the maximum tolerated dose of the study drug
* No known brain metastasis

  * Patients with controlled brain metastasis with no disease progression 60 days after prior therapy and no neurologic signs or symptoms are allowed

    * Patients with signs or symptoms suggestive of brain metastasis are eligible provided that brain metastasis is ruled out by CT scan or MRI
