Detailed Description

This phase I clinical protocol is proposed to evaluate the safety of combined immunotherapy genetics in humans.

This treatment combines the high local cytotoxicity of the suicide gene system (HSV thymidine kinase: HSVt k) / prodrug (ganciclovir: GCV) with the immunostimulation of interleukin2 (hIL2) and immunoamplification of granulocyte and macrophage colony stimulating factor (hGMCSF) in the presence of tumor antigens.

The proposed scheme consists in the periodic intra / peritumoral application of plasmid DNA complexes: cationic lipid (lipoplexes) containing the HSVtk gene, co-administered with the prodrug GCV, and subcutaneous injections of a vaccine (LGvax) produced with formolized extracts of allogeneic melanoma combined with lipoplexes carrying the hIL2 and hGMCSF genes.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Suicide plus immunogene therapy
Intra and peritumoral infiltrates with multiple injections of lipoplexes carrying the HSVtk suicide gene co-administered with GCV and subcutaneous vaccine produced with formolized allogeneic tumor extracts and lipoplexes carrying hIL-2 and hGM-CSF genes.
Biological: Suicide plus immunogene therapy
  1. Intra and peritumoral infiltrates with multiple injections of 0.1 ml/cm2 or 0.2 ml/cm3 of lipoplexes bearing the HSVtk suicide gene (1: 1; 1 mg/ml, according to tumor size), co-administered with GCV (12.5 mg/ml). Patients start with a minimum of 0.5 ml and at the 3rd week, the maximum dose is scaled according to the tumor size up to 2 ml maximum.

  2. Treated simultaneously with a subcutaneous vaccine produced with:

    • Formolized allogeneic tumor extracts and,
    • Lipoplexes carrying hIL-2 and hGM-CSF genes (0.5 mg each).
