Brief Title: Lapatinib and Topotecan in Treating Patients With Ovarian Epithelial Cancer or Primary Peritoneal Cancer That Did Not Respond to Cisplatin or Carboplatin
Official Title: A Phase II Trial of Lapatinib in Combination With Weekly Topotecan in Patients With Platinum-Refractory/Resistant Ovarian and Primary Peritoneal Carcinoma
Study ID: NCT00436644
Brief Summary: RATIONALE: Lapatinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as topotecan, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving lapatinib together with topotecan may kill more tumor cells. PURPOSE: This phase II trial is studying how well giving lapatinib together with topotecan works in treating patients with ovarian epithelial cancer or primary peritoneal cancer that did not respond to cisplatin or carboplatin.
Detailed Description: OBJECTIVES: Primary * Determine the efficacy of lapatinib ditosylate and topotecan hydrochloride, in terms of response, in patients with platinum-resistant or refractory ovarian epithelial or primary peritoneal cavity carcinoma. Secondary * Determine the overall survival time in patients treated with this regimen. * Determine the time to progression in patients treated with this regimen. * Assess the toxicity profile of this regimen in these patients. Translational * Determine the expression patterns of epidermal growth factor receptor, HER2/neu, hypoxia-induced factor 1 alpha, CD31, breast cancer resistance protein, and topoisomerase I by immunohistochemistry using tumor tissue from primary debulking surgery. * Determine the feasibility of monitoring circulating tumor cells with specific biological markers to determine or follow response in these patients. OUTLINE: This is a multicenter study. Patients receive oral lapatinib ditosylate once daily on days 1-28 and topotecan hydrochloride IV over 30 minutes on days 1, 8, and 15. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity. Blood samples are collected at baseline and on day 8 of course 1 (immediately after the topotecan infusion) and are evaluated for pharmacological studies. Tumor tissue samples obtained at debulking surgery are examined by immunohistochemistry for epidermal growth factor receptor, HER1, ErbB1, HER2/neu, ErbB2, hypoxia-induced factor 1 alpha, CD31, platelet endothelial cell adhesion molecule 1, topoisomerase I, and breast cancer resistance protein. After the completion of study treatment, patients are followed periodically for 2 years. PROJECTED ACCRUAL: A total of 39 patients will be accrued for this study.
