Basic Trial Information

Trial Description

Summary

RATIONALE: Bortezomib may stop the growth of tumor cells by blocking the enzymes necessary for tumor cell growth. Drugs used in chemotherapy such as irinotecan use different ways to stop tumor cells from dividing so they stop growing or die. Combining bortezomib with irinotecan may kill more tumor cells.

PURPOSE: This phase II trial is studying how well bortezomib with or without irinotecan works in treating patients with gastroesophageal junction or stomach cancer that can not be removed by surgery.

Further Study Information

OBJECTIVES:

• Determine the response rate in patients with previously untreated adenocarcinoma of the gastroesophageal junction or stomach when treated with bortezomib and irinotecan.

• Determine the response rate in patients with previously treated (closed to accrual as of 9/19/2006) adenocarcinoma of the gastroesophageal junction or stomach when treated with bortezomib.

• Compare the toxic effects and recovery from these effects in patients treated with these regimens.

OUTLINE: Patients are stratified (stratum 2 closed to accrual as of 9/19/2006) according to prior chemotherapy for advanced disease (yes vs no).

• Stratum 1 (Previously untreated patients): Patients receive bortezomib IV over 3-5 seconds on days 1, 4, 8, and 11 and irinotecan IV over 90 minutes on days 1 and 8.

• Stratum 2 (Previously treated patients) (closed to accrual as of 9/19/2006): Patients receive bortezomib as in stratum 1.

In both strata, courses repeat every 21 days in the absence of disease progression or unacceptable toxicity.

PROJECTED ACCRUAL: A total of 33-58 patients (18-33 previously untreated patients and 15-25 previously treated patients [(closed to accrual as of 9/19/2006)]) will be accrued for this study within 12 months.
