Irofulvene in Treating Patients With Stage III or Stage IV Pancreatic Cancer

OBJECTIVES: I. Determine the survival rate at 6 months of patients with stage III or IV unresectable adenocarcinoma of the pancreas treated with 6-hydroxymethylacylfulvene (MGI 114). II. Determine the objective tumor response rate, time to objective tumor response, and duration of response in these patients (if retrospective data is available, time to tumor progression while on prior gemcitabine is determined). III. Determine the clinical benefit of MGI 114 as measured by pain improvement, performance status, and weight. IV. Determine the survival rate at 3, 9, and 12 months in these patients. V. Gain additional information on the toxic effects and safety profile of this regimen.

OUTLINE: This is an open label, multicenter study. Patients receive 6-hydroxymethylacylfulvene (MGI 114) IV over 5 minutes on days 1-5. Treatment is repeated every 28 days in the absence of disease progression or unacceptable toxicity. Patients are followed monthly for up to 1 year after therapy initiation.

PROJECTED ACCRUAL: A total of 50 patients will be accrued for this study within 12-18 months.

DISEASE CHARACTERISTICS: Histologically or cytologically confirmed stage III or IV unresectable adenocarcinoma of the exocrine pancreas Must have been treated with 1 prior gemcitabine regimen, and have documented disease progression either during or within 6 months after completion of therapy Measurable or evaluable disease outside of previously irradiated area No islet cell tumors or lymphoma of the pancreas No significant CNS disease

PATIENT CHARACTERISTICS: Age: 18 and over Performance status: Karnofsky 70-100% Life expectancy: At least 12 weeks Hematopoietic: WBC at least 3,000/mm3 Absolute neutrophil count at least 1,500/mm3 Platelet count at least 100,000/mm3 Hemoglobin at least 9 g/dL Hepatic: Bilirubin no greater than 2 mg/dL AST or ALT no greater than 2 times upper limit of normal (ULN) (no greater than 5 times ULN if liver metastases) Renal: Creatinine no greater than 1.5 mg/dL Cardiovascular: No atrial or ventricular arrhythmias requiring medication No atrial fibrillation (with or without medication) No ischemic event within past 6 months No history of congestive heart failure Other: Not pregnant or nursing Fertile patients must use effective contraception No significant psychiatric disorders No active infection No other prior malignancies within past 5 years, except: Basal or squamous cell skin cancer Carcinoma in situ of the cervix No concurrent serious systemic disorder
