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

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT02424916
Recruitment Status : Completed

Brief 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).

Arm Intervention/treatment
Experimental: Autologous somatic cell therapy
Patients treated with melanoma antigens-specific CD8+ T lymphocytes followed by subcutaneous injections of Proleukin.
Biological: Melanoma antigens-specific CD8+ T lymphocytes
The intervention uses an autologous somatic cell therapy medicinal product. It consists in the intravenous injection of melanoma antigens (Melan-A and MELOE-1) - specific CD8+ T lymphocytes followed by subcutaneous injections of Proleukin.

Primary Outcome Measures :
  1. Clinical and biological safety defined by the NCI (Common Toxicity Criteria - Version 4.0, may 2009, http:// [ Time Frame: Until disease progression during the follow-up period of the study (12 months) ]
    Serious adverse effects of grade 3 and 4 will be considered to decide the suspension of inclusion

Secondary Outcome Measures :
  1. Progression-free survival [ Time Frame: From the date of the first treatment until the date of the first documented progression or the date of death from any cause, whichever came first, assessed up to 2 years ]
  2. Overall survival [ Time Frame: From the date of the first treatment until the date of death, assessed up to 2 years ]
  3. Overall tumor response (complete response, partial response, stable disease) evaluated according to Response Evaluation Criteria in Solid Tumor (RECIST) and immune-related Response Criteria (irRC) [ Time Frame: At 12 months ]
  4. Duration of clinical responses defined as the time interval between the evaluation of the first objective response or stable disease and the first evaluation of disease progression [ Time Frame: At 12 months ]
  5. Persistence of injected specific T cells evaluated by immunomonitoring [ Time Frame: At 3 months ]
