Alternate Title

Bortezomib With or Without Irinotecan in Treating Patients With Cancer of the Gastroesophageal Junction or Stomach (Group Two Closed to Accrual as of 9/19/2006)

Basic Trial Information

Phase Type Status Age Sponsor Protocol IDs Phase II Treatment Closed 18 and over NCI NYWCCC-0103672 NCI-5941, 5941, NCT00061932

Objectives

1. Determine the response rate in patients with previously untreated adenocarcinoma of the gastroesophageal junction or stomach when treated with bortezomib and irinotecan.
2. 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.
3. Compare the toxic effects and recovery from these effects in patients treated with these regimens.

Entry Criteria

Expected Enrollment

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.

Outcomes

Response rate

Gene expression as assessed by microarray at baseline and after completion of study treatment

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.
