---|---|
Experimental: 2 vaccine injections in 1 limb

Experimental: 2 "vaccine injections" in distinct limbs
Groupe3: 2 vaccine injections in distinct limb should include 9 patients that were initially planned; due to premature trial termination, no patients could be enrolled.
Patients of this group should have received the same vaccine but without the MHC class II peptide (MAGE-A3)

Primary Outcome Measures

Measure Description |
Time Frame |
---|---|---|
Ex Vivo Frequency of Melan-A Specific CD8+T Cells
Time Frame: Melan-A specific CD8+ T cells were measured in PBMC collected at the end of Cycle 1 (Week 7), end of Cycle 2 (Week 25), end of Cycle 3 (Week 40), and Follow-up (6 to 18 months after the end of Cycle 3).
|
Cellular immunity was evaluated through the activation and the expansion of Melan-A-specific CD8+ cytotoxic T lymphocytes. Their frequency was measured in the peripheral blood mononuclear cells (PBMC) directly ex vivo (i.e. without prior in vitro expansion) by multicolor flow cytometry with Melan-A ELA tetramers. The fold change for each time point compared to baseline was calculated as: Melan-A-specific CD8+ T cell frequency at the time point/ Melan-A-specific CD8+ T cell frequency at baseline. Significant T cell response is defined by at least 2-fold change of Melan-A-specific CD8+ T cell frequency as compared to pre-immunotherapy. |
Melan-A specific CD8+ T cells were measured in PBMC collected at the end of Cycle 1 (Week 7), end of Cycle 2 (Week 25), end of Cycle 3 (Week 40), and Follow-up (6 to 18 months after the end of Cycle 3).
|
In Vitro Frequency of MAGE A3.DP4-specific CD4+ T Cells Producing Interferon-gamma (IFN-γ)
Time Frame: MAGE A3.DP4 specific CD4+ T cells producing IFN-γ were measured in PBMC collected at the end of Cycle 1 (Week 7), end of Cycle 2 (Week 25), end of Cycle 3 (Week 40), and Follow-up (6 to 18 months after the end of Cycle 3).
|
The activation of peptide-specific CD4+ T cells was analyzed in vitro before and after vaccination by Intracellular Cytokine Staining (ICS). From each patient, total CD4+ T-cells were stimulated in the presence of peptide MAGE-A3.DP4 LP (MAGE-A3243-258 peptide presented by autologous cells). After 10 days, cell cultures were challenged for 4h with the peptide or left unchallenged. Specific CD4+ T cells responses were identified via detection of IFN-γ producing cells. |
MAGE A3.DP4 specific CD4+ T cells producing IFN-γ were measured in PBMC collected at the end of Cycle 1 (Week 7), end of Cycle 2 (Week 25), end of Cycle 3 (Week 40), and Follow-up (6 to 18 months after the end of Cycle 3).
|
In Vitro Frequency of MAGE A3.DP4-specific CD4+ T Cells Producing Tumor Necrosis Factor-alpha (TNF-α)
Time Frame: MAGE A3.DP4 specific CD4+ T-cells producing TNF-α were measured in PBMC collected at the end of Cycle 1 (Week 7), end of Cycle 2 (Week 25), end of Cycle 3 (Week 40), and Follow-up (6 to 18 months after the end of Cycle 3).

|
Frequencies of specific MAGE-A3.DP4-specific CD4+ T cells were quantified by flow cytometry using class II tetramers after 10 days of in vitro stimulation. The fold change for each time point compared to baseline was calculated as: MAGE-A3.DP4-specific CD4+ T cell frequency at the time point/ MAGE-A3.DP4-specific CD4+ T cell frequency at baseline. |
MAGE A3.DP4 specific CD4+ T cells were measured in PBMC collected at the end of Cycle 1 (Week 7), end of Cycle 2 (Week 25), end of Cycle 3 (Week 40) and Follow-up (6 to 18 months after the end of Cycle 3).

Time Frame: In vitro stimulated Melan-A specific CD8+ T cells were measured in PBMC collected at the end of Cycle 1 (Week 7), end of Cycle 2 (Week 25), end of Cycle 3 (Week 40) and Follow-up (6 to 18 months after the end of Cycle 3).
|
After 12 days of in vitro stimulation with Melan-A peptides, CD8+ T cells were analyzed by flow cytometry using tetramer staining. The fold change for each time point compared to baseline was calculated as: Melan-A-specific CD8+ T cell frequency at the time point/ Melan-A-specific CD8+ T cell frequency at baseline.

The assessment of the baseline disease status was performed, using CT (Computed Tomography) scan or PET (Positron Emission Tomography)/ CT scan, at screening visit or within 8 weeks preceding the screening visit. Imagery examinations occurred after the end of each vaccination cycle. The tumor response was assessed according to the classification World Health Organization (WHO) 1979 and defined as:
