Dendritic cells pulsed with multifunctional Wilms' tumor 1 (WT1) peptides combined with multiagent chemotherapy modulate the tumor microenvironment and enable conversion surgery in pancreatic cancer.

ABSTRACT:

Background

We aimed to develop a chemoimmunotherapy regimen consisting of a novel Wilms' tumor 1 (WT1) peptide-pulsed dendritic cell (WT1-DC) vaccine and multiagent chemotherapy and to investigate the safety, clinical outcomes, and WT1-specific immune responses of patients with unresectable advanced pancreatic ductal adenocarcinoma (UR-PDAC) who received this treatment.

Methods

Patients with UR-PDAC with stage III disease (locally advanced (LA-PDAC; n=6)), stage IV disease (metastatic (M-PDAC; n=3)), or recurrent disease after surgery (n=1) were enrolled in this phase I study. The patients received one cycle of nab-paclitaxel plus gemcitabine alone followed by 15 doses of the WT1-DC vaccine independent of chemotherapy. The novel WT1 peptide cocktail was composed of a multifu
