Transfected Dendritic Cell Based Therapy for Patients With Breast Cancer or Malignant Melanoma

August 18, 2015 updated by: Inge Marie Svane

Evaluation of Dendritic Cells Transfected With Survivin, hTERT and p53 mRNA as a Treatment for Patients With Metastatic Breast Cancer or Malignant Melanoma

The primary aim of this study is to evaluate the toxicity of the vaccine and the combination of the vaccine and Cyclophosphamide, and to evaluate the immune response induced by the vaccine. The secondary aim is to investigate the clinical tumour response and duration of tumour and immune response.

Detailed Description

Phase I trial. Single center study; patients will be referred to the study center from other institutions in Denmark. 14 patients will be included in this phase I trial DC vaccination regime consists of primary 6 biweekly intradermal injections with transfected dendritic cells, followed by monthly injections until progression; Cyclophosphamide is used as vaccine adjuvant.

Defined procedures are employed for generation of autologous dendritic cells for clinical application in a classified laboratory. Unmobilized leukapheresis will be used for isolation of large-scale mononuclear cells, and dendritic cells will be generated from monocytes by cytokine stimulation and transfected with mRNA encoding for hTERT, survivin and p53 if the tumour express p53. Frozen preparations of dendritic cells will be prepared using automated cryopreservation. Each patient will receive a minimum of 1x106 dendritic cells per treatment supplemented with Cyclophosphamide 50 mg twice a day every second week. Toxicity including autoimmunity will be evaluated using the Common Toxicity Criteria (CTC).
