A Broad Multi-histology Phase II Study of the Multi-Kinase Inhibitor R935788 (Fostamatinib Disodium) in Advanced Colorectal, Non-small Cell Lung, Head and Neck Hepatocellular and Renal Cell Carcinomas, and Pheochromocytoma and Thyroid Tumors (Multi-H...

Study Summary

Background: * The drug R935788 (fostamatanib disodium) is a kinase inhibitor (i.e., it interferes with cell communication and growth and may prevent tumor growth). * R935788 has shown promising activity in NCI-60 (a panel of 60 diverse human cancer cell lines) against colon cancer, non-small cell lung cancer, and renal cell carcinoma cell lines, as well as in two renal cell xenograft models. * This is an open-label, Phase II study of R935788. Phase I studies in patients with immune thrombocytopenic purpura, rheumatoid arthritis, and lymphoma have demonstrated safety with a continuous dosing schedule, and a maximum tolerated dose has been established. Objectives: * To test an experimental drug called R935788 (fostamatinib disodium) for its ability to stop cancer growth signals, thus slowing the growth of cancer cells in laboratory testing. * To determine the clinical response of R935788 administered orally twice a day on a continuous schedule in patients with colorectal carcinoma, pheochromocytoma, follicular or papillary thyroid cancer, non-small cell lung cancer, hepatocellular, carcinoma of the head and neck, and renal cell carcinoma. * To evaluate the effects, safety, and biochemical response of R935788 therapy. Eligibility: * Patients with colorectal carcinoma, pheochromocytoma, follicular or papillary thyroid cancer, non-small cell lung cancer (excluding squamous cell histology), hepatocellular cancer, carcinoma of the head and neck, and renal cell carcinoma whose disease has progressed after any therapy or who have no acceptable standard treatment options. * Patients must have recovered from toxicities of prior therapies to at least eligibility levels. * Patients who have received radiation or chemotherapy within 4 weeks of study enrollment are not eligible. * Women who are pregnant or breastfeeding are not eligible. Design: * Researchers will conduct the following tests and procedures during the study: * Clinic visits with a physical exam, including

Primary Outcome

Response is assessed by the RECIST (response criteria in solid tumors)criteria. A complete response (CR) is disappearance of all target lesions , partial response (PR) is at least a 30% decrease in the sum of the longest diameter (LD) of target lesions, progressive disease (PD) is at least a 20% increase in the sum of the LD of target lesions, and stable disease (SD) is neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for PD.
