RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die.

PURPOSE: Phase II trial to study the effectiveness of R115777 in treating patients who have recurrent or advanced colorectal cancer.

Condition Intervention Phase
Colorectal Cancer
Drug: R115777
Phase 2

Study Type: Interventional
Study Design: Intervention Model: Single Group Assignment
Masking: Open Label

Further study details as provided by Southwest Oncology Group:

Primary Outcome Measures:
  • Confirmed complete and partial response rate to R115777 [ Time Frame: Once every 8 weeks until progression ]
    Confirmed complete and partial response rate to R115777 in pts with measurable, disseminated colorectal cancer and no prior therapy for advanced disease.

Secondary Outcome Measures:
  • Time to treatment failure and survival [ Time Frame: Once every 8 weeks until progression, then once every 6 months for 2 years, then annually until 3 years from registration ]
    To assess time to treatment failure and survival in this group of patients.

  • Frequency & severity of toxicities [ Time Frame: Weekly for 8 weeks and then once every 4 weeks until progression ]
    To assess the frequency and severity of toxicities associated with this treatment.

Enrollment: 62
Study Start Date: June 2000
Study Completion Date: July 2006
Primary Completion Date: July 2006 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: R115777
R115777, 300mg PO BID on Days 1-21. 1 cycle=28 days.
Drug: R115777
300mg P.O. BID.
Other Name: NSC-702818

Detailed Description:

OBJECTIVES: I. Determine the response rate to R115777 in patients with disseminated colorectal cancer who have been previously treated for advanced disease. II. Assess the time to treatment failure and survival of these patients with this treatment regimen. III. Determine the frequency and severity of toxicities of this regimen in these patients.

OUTLINE: This is a multicenter study. Patients receive oral R115777 twice daily on days 1-21. Treatment continues every 28 days in the absence of disease progression or unacceptable toxicity. Patients are followed every 6 months for 2 years and then annually thereafter.

PROJECTED ACCRUAL: A total of 50 patients will be accrued for this study over 5-7 months.
