NCT00103168
First received: February 7, 2005

  Purpose

RATIONALE: Imatinib mesylate may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Giving imatinib mesylate after surgery may kill any remaining tumor cells. It is not yet known whether imatinib mesylate is more effective than observation only in treating gastrointestinal stromal tumor.

PURPOSE: This randomized phase III trial is studying imatinib mesylate to see how well it works compared to observation only in treating patients who have undergone surgery for localized gastrointestinal stromal tumor.


Condition Intervention Phase

Phase 3

Study Type: Interventional
Study Design: Allocation: Randomized
Masking: Open Label

Primary Outcome Measures:
  • Overall survival [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Relapse-free survival [ Designated as safety issue: No ]
  • Relapse-free interval [ Designated as safety issue: No ]
  • Adverse events [ Designated as safety issue: Yes ]

Estimated Enrollment: 750
Study Start Date: December 2004
Primary Completion Date: October 2008 (Final data collection date for primary outcome measure)
Detailed Description:

OBJECTIVES:

Primary

  • Compare imatinib monotherapy failure free survival of patients in the two regimens.

Secondary

  • Compare relapse-free survival,relapse-free interval and overall survival in patients treated with these regimens.
  • Determine the safety of this drug in these patients.

OUTLINE: This is a randomized, open-label, multicenter study. Patients are stratified according to participating center, risk category (high vs intermediate), tumor site (gastric vs other), and resection level (R0 vs R1). Patients are randomized to 1 of 2 arms.

  • Arm I: Patients receive adjuvant oral imatinib mesylate once daily for 2 years in the absence of disease progression or unacceptable toxicity.
  • Arm II: Patients are observed (without receiving further antitumoral therapy) every 3 months for 2 years.

After completion of study treatment, patients in arm I are followed every 3 months for 2 years. All patients are then followed every 4 months for 3 years and at least annually thereafter.

PROJECTED ACCRUAL: A total of 750 patients will be accrued for this study within 5 years.
