The goal of this clinical research study is to find the highest tolerable dose of the combinations of pazopanib and either lapatinib or trastuzumab that can be given to patients with advanced cancer. The safety of the drug combinations will also be studied.
Pazopanib is designed to block the growth of blood vessels that supply nutrients needed for tumor growth. This may prevent or slow the growth of cancer cells.
Lapatinib is designed to prevent or slow down the growth of cancer cells by blocking 2 proteins on the surface of the cancer cell, which are HER 1 and HER 2 receptors.
Trastuzumab is designed to prevent or slow down the growth of cancer cells by blocking proteins inside the cancer cell, called the Her2/neu receptor.

- Maximum Tolerated Dose (MTD) of Pazopanib in Combination with Lapatinib or Trastuzumab [ Time Frame: 28 day cycle ]MTD is defined as highest dose in which incidence of dose limiting toxicity (DLT) was less than 33% (approximately two or more participants in a dose cohort).
- Tumor Response [ Time Frame: End of second 28 day cycle ]Computed tomography (CT) scan, magnetic resonance imaging (MRI) scan, positron emission tomography (PET) scan, and/or x-ray to check the status of the disease. Tumor response calculated by Response Evaluation Criteria in Solid Tumors (RECIST) and World Health Organization Working Group (WHO) criteria. A tumor response is defined as one or more of the following: (1) stable disease for more than or equal to 4 months, (2) decrease in measurable tumor (sentinel lesions) by more than or equal to 20% by RECIST criteria, (3) decrease in tumor markers by more than or equal to 25% or (4) a partial response according to the Choi criteria.
