Study Overview
Brief Summary
This is an open label, phase II trial study of adjuvant GVAX pancreas vaccine in patients with pancreatic cancer.
Detailed Description
Eligible participants will receive by intradermal administration the GVAX pancreas vaccine consisting of two irradiated allogeneic pancreatic tumor cell lines transfected with the granulocyte macrophage-colony stimulating factor (GM-CSF) gene.
There will be two cohorts of research participants:
- Participants previously vaccinated with GVAX pancreas vaccine. These participants will receive booster vaccinations as a continuation of care. Vaccination repeats every 6 months in the absence of disease progression or unacceptable toxicity.
- Participants who were not previously vaccinated with GVAX pancreas vaccine (vaccine naive). These participants received priming vaccinations once a month for 3 months followed by booster vaccinations every 6 months.

Outcomes
Primary Outcomes
Number of Patients Experiencing a Grade 3 or Above Treatment- Related Toxicity
Time Frame: 14 years
When calculating the incidences of adverse events, each adverse event (as defined by NCI CTCAE v3) will be counted only once for a given subject.
Secondary Outcomes
- Disease-free Survival (DFS)(16 years)
- Overall Survival (OS)(16 years)
