  Purpose

Objectives:

This is an exploratory study, consisting of two parts. In part I a dose escalation is performed and the primary objective is the safety of different doses of TLR-dendritic cell (TLR-DC). In part II TLR-DC vaccination will be compared with cytokine-matured DC vaccination and the primary objective of this part is the immunological response to TLR-DC vaccination, with toxicity and clinical efficacy being secondary objectives. These studies will provide important data on the safety and immunological effects of TLR-matured DC.

Study design:

This study is an open label prospective exploratory intervention study.

Study population:

The investigators' study population consists of HLA-A2.1 positive melanoma patients, with proven expression of melanoma associated tumor antigens gp100 and tyrosinase. Melanoma patients with regional lymph node metastasis in whom a radical lymph node dissection is planned or performed within 2 months of inclusion in this study (further referred to as stage III) and melanoma patients with measurable distant metastases (further referred to as stage IV) will be included.

Primary Outcome Measures:
  • Toxicity of TLR-matured DC (part I) and immunological response upon vaccination with TLR-matured DC (part II) [ Time Frame: 3 years ]

Secondary Outcome Measures:
  • vaccination related toxicity [ Time Frame: 5 years ]
    in terms of local injection site reaction, flu-like symptoms, or otherwise related to vaccination, scored according to CTC version 3.0

  • clinical efficacy (progression free survival) [ Time Frame: 5 years ]
    time to progression from date of start (apheresis) will be recorded


Enrollment: 20
Study Start Date: June 2009
Study Completion Date: November 2014
Primary Completion Date: November 2014 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: cytokine matured DC
vaccination with autologous dendritic cells matured with standard cytokine cocktail and electroporated with mRNA encoding tumor associated antigens
Biological: autologous dendritic cell vaccination
Autologous monocyte-derived dendritic cells electroporated with mRNA encoding gp100 and tyrosinase and matured with either cytokines or TLR ligands. Dendritic cells are vaccinated intradermal/intravenously 3 times with biweekly intervals every 6 months, if no signs of progression, for a total of 9 vaccinations.
Experimental: TLR ligand matured DC
vaccination with autologous TLR-ligand matured dendritic cells electroporated with mRNA encoding tumor associated antigens
Biological: autologous dendritic cell vaccination
Autologous monocyte-derived dendritic cells electroporated with mRNA encoding gp100 and tyrosinase and matured with either cytokines or TLR ligands. Dendritic cells are vaccinated intradermal/intravenously 3 times with biweekly intervals every 6 months, if no signs of progression, for a total of 9 vaccinations.
