ClinicalTrials.gov Identifier:	NCT00364364

Purpose

This no treatment research study is being done to find a safe and an appropriate dose of antibody (protein) against tumor cells to best target the cancer in people with pancreatic cancer. To do this, this no-treatment research study will compare two doses of an antibody called hPAM4 IgG when combined with a radioactive element, Indium-111.

Primary Outcome Measures:

Examine the pharmacokinetics and tumor targeting of 111In-DOTA-hPAM4 anti-MUC-1 IgG given intravenously to patients with known or a suspicion of primary or recurrent pancreatic cancer.
An examination of how the pharmacokinetics and tumor targeting are affected by the amount of hPAM4 IgG administered.
Targeting with 111In-hPAM4 will be compared to other radiological (e.g., CT) and nuclear (FDG-PET; optional)findings.
For patients who undergo surgery after the 111In-hPAM4 study, targeting will be correlated against surgical findings.

Secondary Outcome Measures:

Correlate tumor targeting, when feasible, with the following:Immunohistology using the hPAM4 antibody
Histology,Serum antigen content
Determine normal organ and, whenever possible, tumor dosimetry for 90Y-hPAM4 IgG based on the distribution and tumor targeting of 111In-hPAM4-IgG.
Monitor the development of antibody formation to the hPAM4, when feasible.
Targeting with 111In-hPAM4 will be compared to other radiological (e.g., CT) and nuclear (FDG-PET; optional)findings.

Detailed Description:

This is an open-label, single-center, non-randomized, single-arm, pilot imaging study to determine the pharmacokinetics, biodistribution, and tumor targeting of an indium-111 (111In)-labeled, humanized anti-MUC1 antibody, designated hPAM4 IgG1 in patients with known pancreatic cancer. The primary objective of this trial is to examine how changing the protein dose will affect these parameters with the intent to determine if a single protein dose can be selected to optimize tumor targeting. It is expected that these data will aid in the selection of an appropriate protein dose to be used in a Phase I therapy trial with yttrium-90 (90Y)-labeled hPAM4 IgG. The secondary objective is to monitor safety.

Pharmacokinetics, biodistribution, tumor targeting, and dosimetry (modeling for 90Y) will be assessed against clinical parameters, such as pre-study PAM4-reactive MUC-1 antigen in the serum, tumor size, location, histopathology, immunohistology, and if possible, antigen content by extraction of tumor sample.

Known history of active coronary artery disease, unstable angina, myocardial infarction, or congestive heart failure present within 6 months or cardiac arrhythmia requiring anti-arrhythmia therapy.
Known history of active COPD, or other moderate-to-severe respiratory illness present within 6 months.

B. Subjects who have signs of intestinal obstruction.

C. Subjects who are pregnant are excluded. D. Subjects who have a measurable antibody response to hPAM4 in their pre-study sample or who are proven allergic upon testing with the agent.

E. Patients who are known to have HIV.

F. Patients who have a known history of Hepatitis B or C or any other serious liver abnormality will be excluded from enrollment.

G. Prisoners or other institutionalized persons.
