Summary

Lapatinib ditosylate may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. This phase II trial is studying how well lapatinib ditosylate works in treating patients with unresectable liver or biliary tract cancer

Detailed description

PRIMARY OBJECTIVES: I. To evaluate the objective response rate (complete response \[CR\] + partial response \[PR\]) as defined by the Response Evaluation Criteria in Solid Tumors (RECIST) criteria in each group of patients. SECONDARY OBJECTIVES: I. To evaluate the progression free survival at 6 months. II. To evaluate the toxicity profile of this treatment in each group of patients. III. To evaluate median overall survival, 6 and 12 months survival rates. IV. To assess target-epidermal growth factor receptor (EGFR)/EGFR-P protein expression and the genes that regulate the cell cycle and apoptosis, which are either downstream of or cross-talk with the EGFR signaling pathway, to explore their association with clinical outcome. V. To measure expression profile and mutations of genes critical for EGFR and (v-erb-b2 erythroblastic leukemia viral oncogene homolog 2 (ERBB2 signaling pathways with particular relevance to GW572016, and to explore new gene-drug relationships as relating to hepatocellular and biliary carcinomas. OUTLINE: This is a multicenter study. Patients receive oral lapatinib ditosylate once daily on days 1-28. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity. PROJECTED ACCRUAL: A total of 70 patients will be accrued for this study within 1 year.
