The aim of this study was to evaluate the tolerability of intratumoral administered recombinant human interleukin-12 (rhIL-12) in patients with head and neck squamous cell carcinoma. Six patients were treated once a week at two dose levels of 100 or 300 ng/kg, respectively, up to 24 weeks. The primary end point was to assess the toxicity and safety of(More)
Objective: Dendritic cells (DC) play an essential role in the regulation of both immunity and tolerance. DC orchestrate the attraction of inflammatory cells by the production of various chemokines (CK). Recently, It was suggested that Fc gamma receptors (FcγR) are involved in the regulation of DC function. The aim of the study was to assess the expression(More)
Tumor-derived peptides are used frequently as antigen (Ag) source in dendritic cell (DC) therapy in cancer patients. An alternative is to load DC with tumor-associated Ag (TAA)-encoding RNA. RNA-loading obviates prior knowledge of CTL and Th epitopes in the Ag. Multiple epitopes for many HLA alleles (both MHC class I and class II) are encoded by the RNA and(More)
CC chemokine ligand 18/dendritic cell-chemokine 1 (CCL18/DC-CK1) is a CC chemokine, preferentially expressed by DC, which acts as a chemoattractant for naive T cells and mantle zone B cells. Applying a newly developed CCL18/DC-CK1 sandwich enzyme-linked immunosorbent assay, we demonstrate that DC secrete high amounts of CCL18/DC-CK1 and that this expression(More)
The objective of this Phase II study was to evaluate the pharmacodynamic and immune effects of intratumorally administered recombinant human interleukin-12 (IL-12) on regional lymph nodes, primary tumor, and peripheral blood. Ten previously untreated patients with head and neck squamous cell carcinoma were injected in the primary tumor two to three times,(More)
