Lapatinib Ditosylate and Capecitabine in Treating Patients With Metastatic Pancreatic Cancer

2014-07-23 21:13:35 | BioPortfolio

Summary

RATIONALE: Lapatinib ditosylate may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as capecitabine, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving lapatinib ditosylate together with capecitabine may kill more tumor cells.

PURPOSE: This phase II trial is studying how well giving lapatinib ditosylate together with capecitabine works in treating patients with metastatic pancreatic cancer.

Description

OBJECTIVES:

Primary

- To evaluate the efficacy of lapatinib ditosylate and capecitabine as first-line therapy, in terms of overall survival, in patients with metastatic pancreatic cancer.

Secondary

- To evaluate the progression-free survival of patients treated with this regimen.

- To evaluate the overall response rate (complete and partial responses) in patients treated with this regimen.

- To evaluate the clinical benefit (complete response, partial response, or stable disease for ≥ 6 months) of this regimen in these patients.

- To evaluate the qualitative and quantitative toxicity associated with this regimen in these patients.

- To determine the intra-tumoral expression of ErbB1 (EGFR) and ErbB2 (HER2/neu) in these patients.

- To seek pilot information on the intra-tumoral expression of markers of tumor resistance and sensitivity to treatment, including resistance drug pump expression and growth factor receptor expression.

- To collect pre- and post-treatment serum samples from these patients for proteomic analyses to elucidate if any serum cancer marker profiles can be detected.

OUTLINE: This is a multicenter study.

Patients receive oral lapatinib ditosylate once daily on days 1-21 and oral capecitabine twice daily on days 1-14. Courses repeat every 21 days in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up every 6-12 weeks.

Medical and Biotech [MESH] Definitions

A deoxycytidine derivative and fluorouracil PRODRUG that is used as an ANTINEOPLASTIC ANTIMETABOLITE in the treatment of COLON CANCER; BREAST CANCER and GASTRIC CANCER.

Tumors or cancer of the PANCREAS. Depending on the types of ISLET CELLS present in the tumors, various hormones can be secreted: GLUCAGON from PANCREATIC ALPHA CELLS; INSULIN from PANCREATIC BETA CELLS; and SOMATOSTATIN from the SOMATOSTATIN-SECRETING CELLS. Most are malignant except the insulin-producing tumors (INSULINOMA).

Star-shaped, myofibroblast-like cells located in the periacinar, perivascular, and periductal regions of the EXOCRINE PANCREAS. They play a key role in the pathobiology of FIBROSIS; PANCREATITIS; and PANCREATIC CANCER.

A 36-amino acid pancreatic hormone that is secreted mainly by endocrine cells found at the periphery of the ISLETS OF LANGERHANS and adjacent to cells containing SOMATOSTATIN and GLUCAGON. Pancreatic polypeptide (PP), when administered peripherally, can suppress gastric secretion, gastric emptying, pancreatic enzyme secretion, and appetite. A lack of pancreatic polypeptide (PP) has been associated with OBESITY in rats and mice.

Extracts prepared from pancreatic tissue that may contain the pancreatic enzymes or other specific uncharacterized factors or proteins with specific activities. PANCREATIN is a specific extract containing digestive enzymes and used to treat pancreatic insufficiency.
