简要总结
The purpose of this study is to determine whether vaccination with melanoma antigen peptides [Melan-A/Mart-1 (both EAA and ELA), NY-ESO-1b analog, Long NY-ESO-1 LP and MAGE-A10] and Montanide, CpG adjuvants and low dose rIL-2 can induce an immune response in melanoma patients and to assess the safety of this vaccination.
详细描述
Current peptide vaccines suffer from low efficiency, since they induce only weak immune activation. We have recently confirmed that in humans the immune response was readily detectable in local lymph nodes while no or only weak activation could be identified in circulating lymphocytes. Increased doses of antigen and adjuvant allow a better extension from local to systemic immune responses.
- Group 1 : vaccination with Melan-A analog (ELA) peptide + Montanide
- Group 2 : vaccination with Melan-A analog (ELA), NY-ESO-1b analog and MAGE-A10 peptides + Montanide
- Group 3: vaccination with Melan-A analog (both EAA and ELA), Mage-A10, NY-ESO-1 peptides+ Montanide + CpG adjuvant
- Group 4: vaccination with Melan-A (ELA), Mage-A10,long NY-ESO-1LP peptides + Montanide + CpG
- Group 5: vaccination with Melan-A (both EAA and ELA), Mage-A10, long NY-ESO-1 LP peptides + Montanide + CpG + low dose rIL-2

结局指标
主要结局
Change From Baseline in Mean Number of Adverse Events (Serious and Non Serious Events)
时间窗: Change from baseline to end of Cycle 1 (3 months), end of Cycle 2 (8 months), end of Cycle 3 (13 months) and end of Boost Cycles (18 months to 23 months).
Safety of the vaccination was assessed according to the National Cancer Institute Common Toxicity Criteria (NCI CTC) scale. The adverse events (AE) and serious adverse events (SAE) were registered at each study visit during the 3 vaccination cycles and boost cycles.
Fold Change From Baseline in ex Vivo Melan-A-specific CD8+ T Cells Frequency During the Vaccination Period
时间窗: Fold change from baseline in Melan-A-specific CD8+T-cells at the end of Cycle 1 (3 months), at the end of Cycle 2 (8 months), at the end of Cycle 3 (13 months) and if applicable at the end of Boost cycles (18 to 24 months).
Ex vivo frequency of Melan-A-specific CD8+ T cells was measured by multimer technique (tetramer assay) in a multicolor flow cytometry analysis. 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.
