Patient case: 73-year-old male with melanoma; genetic feature: tumor cells negative for PD-L1 expression

Clinical trial: Adoptive Transfer of Specific Melanoma Antigens CD8+ T Cells in Metastatic Melanoma Patients: a Phase I/II Study

Summary: This study evaluates the safety as well as the potential clinical efficacy of an adoptive transfer of CD8+ T cells, sorted with HLA-peptide multimers and specific for Melan-A and MELOE-1 melanoma antigens, to patients suffering from advanced metastatic melanoma (stages IIIc and IV).


Eligibility: Inclusion Criteria:

  -  Disease measurable / evaluable within 28 days before the first administration of study treatment
  -  Negative viral serology (HIV 1/2, Ag p24 , HTLV 1/2 , hepatitis B and C, syphilis)
  -  Results of analysis:
  -  Hemoglobin ≥ 10 g / dl or ≥ 6.25 mmol / l
