Phase II Study of MGI-114 (NSC# 683863) Administered Intravenously for Five Days Every 28 Days to Patients With Metastatic Colorectal Cancer
Phase II Study of MGI-114 (NSC# 683863) Administered Intravenously for Five Days Every 28 Days to Patients With Metastatic Colorectal Cancer
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 irofulven in treating patients with metastatic colorectal cancer.
OBJECTIVES: I. Assess the antitumor activity of 6-hydroxymethylacylfulvene (MGI-114) when given daily for 5 days every 28 days to patients with metastatic adenocarcinoma of the colon or rectum. II. Evaluate the qualitative and quantitative toxicities of MGI-114 given on this schedule in this patient population.
OUTLINE: Patients receive 6-hydroxymethylacylfulvene (MGI-114) IV over 5 minutes daily for 5 consecutive days. Courses are repeated every 28 days. The minimum treatment period is 2 courses. Treatment continues indefinitely in the absence of unacceptable toxic effects or disease progression. Patients are followed at the end of every other course while on the study, and then every 3 months thereafter until death.
PROJECTED ACCRUAL: A total of 18-35 patients will be accrued for this study within 6-10 months.
DISEASE CHARACTERISTICS: Histologically confirmed metastatic adenocarcinoma of the colon or rectum Bidimensionally measurable lesions Sentinel lesions outside the field of any prior radiation therapy No confirmed or suspected brain metastases
