Scientific title
Phase I trial of RAB38/NY-MEL-1(50-58) peptide combined with Montanide® ISA-51 in HLA-A*0201 patients with stage III/IV malignant melanoma
Acronym
RAB38
Study hypothesis
In contrast to other solid tumours, immunology plays a major role in malignant melanoma. RAB38/NY-MEL-1 is a tumour antigen, which is exclusively expressed in melanocytes. Furthermore, antibodies against this polypeptide have exclusively been identified in the sera of patients with malignant melanoma. Therefore, the RAB38/NY-MEL-1 protein is an interesting target for immunisation strategies in these patients. Patients can be included in this study after failure or intolerance of standard chemotherapy. For these patients, other salvage treatments are not yet established and no therapy has been proven to be superior to best supportive care alone. The RAB38/NY-MEL-1 polypeptide has not been used in vaccination protocols before. Other tumour antigens (e.g. NY-ESO 1) have been studied in similar studies, where single patients responded to the vaccination and achieved regression of the tumour manifestations. The tolerability of the vaccination protocols described before was good and severe toxic side effects did not occur in most studies. Within this study, 9 patients with advanced malignant melanoma will be vaccinated with the RAB38/NY-MEL-1(50-58) peptide mixed with Montanide® ISA-51 as an adjuvant.

Condition
Malignant melanoma stage III/IV
Intervention
Patients will receive RAB38/NY-MEL-1 peptide 400 µg mixed with 0.5 mL of Montanide® ISA-51 by intradermal injections, every 3 weeks (weeks 1, 4, 7, 10, 13 and 16) for six doses. Patients without disease progression in the absence of dose-limiting toxicity will receive continued treatment starting 3 weeks after the last injection. Treatment courses will be continued until tumour progression. No dose adjustments during the study are planned.
