Tumour infiltrating lymphocytes (Iovance Biotherapeutics)

To improve the efficacy of immunotherapy for cancer, recent studies focused on specific targets to redirect the immune network toward eradicating a variety of tumors and ameliorating the self-destructive process.
A clinically relevant immune escape mechanism in melanoma is the activation of the Programmed cell Death-1 (PD-1) receptor on infiltrating T cells. By blocking PD-1 receptors with anti-PD-1 monoclonal antibodies (mAbs), T-cells are unaffected by the PD-L1 expressed on tumor cells and the patients T cells are free to respond to melanoma antigens and attack tumor cells. So the objective of this trial is to evaluate the safety and the efficacy of a combined therapy Nivolumab and adoptive T cell therapy in metastatic melanoma patients.
