Article Title: | A phase I pilot study of autologous heat shock protein vaccine HSPPC-96 in patients with resected pancreatic adenocarcinoma |
Abstract: | We performed a phase I pilot study to determine if autologous vaccine HSPPC-96 (gp96, Oncophage®) could be purified from completely resected pancreas adenocarcinomas, to determine patient tolerance of vaccine and to explore immune responses and clinical outcomes of these patients. Subjects were vaccinated with 5 μg of autologous HSPPC-96 weekly for 4 doses. Serial ELISPOT assays of T cells for antitumor reactivity were performed. Subjects received neither adjuvant chemotherapy nor radiation. Ten patients received a full course of vaccinations. No dose-limiting toxicities were encountered. Immediate freezing in liquid nitrogen of the tumor specimen resulted in improved vaccine yield. Median overall survival is 2.2 years (Kaplan-Meier estimate). Autologous anti-HSPPC-96 ELISPOT reactivity increased significantly in 1 of 5 patients examined and a second had an increase of unclear significance. Three of 10 treated patients are alive without disease at 2.6, 2.7, and 5.0 years follow-up. There was no observed correlation between immune response and prognosis. This study demonstrates the feasibility of preparing HSPPC-96 from pancreatic adenocarcinomas. Examination of this novel approach using multiple dose levels is 1 approach to further investigate the immunogenicity and clinical utility of HSPPC-96 vaccination in this setting. © 2006 Springer Science+Business Media, Inc. |
