Safety Study of 90Y-hMN14 to Treat Pancreatic Cancer

The purpose of this trial is to determine the safety of 90Y-hMN14 at different dose levels in the treatment of pancreatic cancer.

Disease Characteristics:

• Patients with a documented histologic or cytologic diagnosis of a pancreatic malignancy
• Patients with recurrent, advanced and/or metastatic disease, who have either failed standard therapy or are not eligible for any alternate therapies of higher therapeutic priority.
• Patients with at least one identified (confirmed) and measureable tumor site.

Prior/Concurrent Therapy:

• Surgery: Patients are excluded if they have had major surgery either during or within four weeks prior to study entry.
• Chemotherapy: Patients must have failed standard therapy or are not eligible for any alternate therapies of higher therapeutic priority.
• Biologic Therapy: Patients who have received a chimeric, CDR-grafted (humanized), or human IgG will be eligible provided pre-study evaluations demonstrate no significant reactivity with hMN14 IgG (i.e., HAHA)
• Radiotherapy: No prior radiotherapy within four weeks of study entry. No prior external beam irradiation to a field that includes more than 30% of the red marrow. No prior radiation to maximal tolerable levels for any critical organ (e.g., 3,000 cGy for the liver; 2,000 cGy for the lungs and kidneys).
• Other: Any experimental therapy (i.e., drugs, biologics, procedures) for the primary malignancy, either during or within four weeks prior to study entry.

Patient Characteristics/Inclusion Criteria:

• Performance Status: Patients with a Karnofsky performance status > 70% (or equivalent, ECOG 0-1) and an expected survival rate of at least 3 months
• Hematopoietic: Hemoglobin > 10g/dL; WBC > 3000 per mm3; Granulocyte count > 1500 per mm3; platelet count > 100,000 per mm3
• Hepatic: Total bilirubin < 1.5 times the institutional upper limit of normal (IULN); AST or ALT < 2 X IULN
• Renal: Creatinine < IULN
• Cardiovascular: Patients with LVEF >/= 50% by required MUGA/2D-ECHO study
• Pulmonary: Patients with DF and FEV1 >/= 60 % by required Pulmonary Function Tests
• Gastrointestinal:Patients with severe anorexia or other related symptomology are excluded
• Central Nervous System: Patient with known metastatic disease to the CNS are excluded
• Other: Patients who have had a prior imaging study with a murine antibody may be included. Patients agreeing to use a medically effective method of contraception during and for a period of three months after the treatment period. A pregnancy test will be preformed on each premenopausal female of childbearing potential immediately prior to entry into the study. Patients able to understand and give written informed consent.
