Phase II Study With Immunotherapy With Dendritic Cells and Tumor Infiltrating Lymphocytes in Solid Tumors

May 7, 2010 updated by: Clinica Universidad de Navarra, Universidad de Navarra

Background: cellular immunotherapy with dendritic cells (DC) loaded with tumor antigens has shown clinical activity, although in a small number of patients. Therefore, is is mandatory to improve the results of this strategy and to closely monitor immunologic response and cell migration in order to improve our understanding of mechanisms of action and to settle future fields of development..

Objectives: Primary: to confirm clinical activity of this strategy, determining tumor response (RECIST criteria). Secondary: to determine: (1) safety; (2) antitumoral immune response and (3) DC migration in the organism

Methodology: phase II trial in patients with advanced renal cell carcinoma and melanoma. We will perform repeated immunizations with DC loaded with the patient´s tumor.

Detailed Description

Background: cellular immunotherapy with dendritic cells (DC) loaded with tumor antigens has shown clinical activity, although in a small number of patients. Therefore, is is mandatory to improve the results of this strategy and to closely monitor immunologic response and cell migration in order to improve our understanding of mechanisms of action and to settle future fields of development..

Objectives: Primary: to confirm clinical activity of this strategy, determining tumor response (RECIST criteria). Secondary: to determine: (1) safety; (2) antitumoral immune response (through study of delayed hypersensitivity; ELISPOT; activity of Natural Killer cells; and serum cytokine concentrations); and (3) DC migration in the organism, by labeling with 111-Indium oxinate

Methodology: phase II trial in patients with advanced renal cell carcinoma and melanoma. We will perform repeated immunizations with mature DC loaded with autologous tumor. We will introduce the following novel elements to enhance efficacy (1) Pre-treatment with cyclophosphamide to reduce regulatory / suppressor T cells; (2) maturation/activation of DC induced by TNF-alfa, IFN-alfa and double stranded RNA (GMP-manufactured poly I:C), aimed at replication of the phenomena observed during a viral infection (3) intranodal DC administration in inguinal lymph nodes (4) four daily doses (repeated every 24 hours) in two cycles one month apart (5) scintigraphic follow-up of a tracing dose of 111-In labelled DC and (6) ) systemic treatment with PEG-IFN alfa and GM-CSF to potentiate activity.
