Lapatinib Ditosylate and Capecitabine in Treating Patients With Metastatic Pancreatic Cancer

NCT ID: NCT00962312

Last Updated: 2014-12-31

Basic Information

• Recruitment Status: COMPLETED
• Clinical Phase: PHASE2
• Total Enrollment: 9 participants
• Study Classification: INTERVENTIONAL
• Study Start Date: 2009-01-31

Brief 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.

Detailed 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.

Eligibility Criteria

Inclusion Criteria

DISEASE CHARACTERISTICS:

• Histologically or cytologically confirmed metastatic adenocarcinoma of the pancreas

• No active hepatic or biliary disease, except for Gilbert's syndrome, asymptomatic gallstones, liver metastases, or stable chronic liver disease per investigator assessment
• No active cardiac disease within the past 6 months, including any of the following:

• Uncontrolled angina
• Clinically significant arrhythmia, except for asymptomatic atrial fibrillation requiring anticoagulation
• Myocardial infarction
• Uncontrolled or symptomatic congestive heart failure
