Inclusion Criteria: * Written informed consent signed. * Male or female patient with histologically proven stage IIIB or IIIC cutaneous melanoma presenting with macroscopic lymph node involvement suitable for surgery. * The patient must have been surgically rendered free of disease before the randomization. * Patient is ≥ 18 years old at the time of signing the informed consent form. * The patient's lymph node tumor shows expression of the MAGE-A3 gene. * The patient has fully recovered from surgery. * ECOG performance status of 0 or 1 at the time of randomization. * The patient must have adequate organ functions as assessed by standard laboratory criteria. * If the patient is female, she must be of non-childbearing potential, or practice adequate contraception. * In the opinion of the investigator, the patient can and will comply with all the requirements of the protocol. Exclusion Criteria: * The patient suffers from a mucosal or ocular melanoma. * The patient has or has had any history of in-transit metastases * The patient has been treated or is scheduled to be treated with an adjuvant anticancer therapy after the surgery that qualifies the patient for inclusion in the present trial. * The patient requires concomitant chronic treatment with systemic corticosteroids or any other immunosuppressive agents. * Use of any investigational or non-registered product (drug or vaccine) other than the study treatment. * The patient has a history of autoimmune disease. * The patient has a family history of congenital or hereditary immunodeficiency. * The patient is known to be positive for Human Immunodeficiency Virus (HIV) or has another confirmed or suspected immunosuppressive or immunodeficient condition. * History of allergic disease or reactions likely to be exacerbated by any component of the treatments. * The patient has psychiatric or addictive disorders that may compromise his/her ability to give informed consent or to comply with the trial procedures. * The patient has concurrent severe medical problems, unrelated to the malignancy, that would significantly limit full compliance with the study or expose the patient to unacceptable risk. * The patient has previous or concomitant malignancies at other sites, except effectively treated non-melanoma skin cancers or carcinoma in situ of the cervix or effectively treated malignancy that has been in remission for over 5 years and is highly likely to have been cured. * The patient has an uncontrolled bleeding disorder. * For female patients: the patient is pregnant or lactating.

Outcomes

Primary Outcomes

Disease Free Survival (DFS)

DFS = time to event from randomization to the date of first disease recurrence (as assessed by investigator) or the date of death (whatever cause), whichever occurred first. DFS was expressed as the person-year rate i.e. the number of patients with at least one event (n) over the sum of the follow-up periods in years (T), until the first occurrence of a recurrence/death. Types of recurrence to be considered as an event included loco-regional and distant metastases. Any death occurring without prior documentation of tumor recurrence was considered as an event (not censored in the stat. analysis) as this approach was less prone to introduce bias. If no event occurred by the time of analysis, then the time to event was censored at the last assessment date (tumor assessment/visit) of the patient. Any new primary cancer at another site, including second primary melanoma, was not considered as a recurrence and had to be reported as a Serious Adverse Event (SAE).

Time frame: At Final analysis (Month 30 = Year 2.5)

Disease Free Survival (DFS)

Time frame: At follow-up analysis (up to Year 5)

Secondary Outcomes

Overall Survival (OS)

Overall Survival (OS) was defined as the time to event from randomization to the date of death, irrespective of the cause of death. OS was expressed as the person-year rate i.e. the number of patients with death (n) over the sum of the follow-up periods in years (T). Patients alive at the time of the analysis were censored on the date last known to be alive.

Disease-free Specific Survival (DFSS)

Disease Free Specific Survival (DFSS) was defined as the time to event from randomization to the date of first recurrence of disease or date of death due to melanoma (cause as assessed by investigator), whichever occurred first. DFSS was expressed as the person-year rate i.e. the number of patients with at least one event (n) over the sum of the follow-up periods in years (T), until the first occurrence of a recurrence/death. Patients who died due to a cause other than the disease under study and patients alive at the time of analysis were censored on the date of last assessment (visit or tumor assessment).

Time frame: At Final analysis (Month 30 = Year 2.5)

Distant Metastasis-free Survival (DMFS)

Distant Metastasis Free Survival (DMFS) was defined as the time to event from randomization to the date of first distant metastasis or date of death, whichever occurred first. DMFS was expressed as the person-year rate i.e. the number of patients with at least one event (n) over the sum of the follow-up periods in years (T), until the first occurrence of distant metastasis/death. Patients alive and without distant metastases were censored at the date of last assessment (visit or tumor assessment, or date of last tumor assessment as documented during the yearly contact follow-up period).

Time frame: At Final analysis (Month 30 = Year 2.5)

Health-related Quality of Life

The assessment of health-related quality of life was restricted to patients who consented to study participation after Protocol Amendment 1 became effective at their study site, and for whom a validated version of the Euro Quality of Life-5D (EQ-5D) questionnaire was available in their native language. The EQ-5D comprises a 5-dimensional descriptive system (mobility, self-care, usual activities, pain/discomfort and anxiety/depression), where each item has 3 levels and together they define 243 possible health states. For each health state, a value (utility) was determined by using an additive algorithm. These utility scores were calculated for each patient at each timepoint at which an EQ-5D questionnaire was completed. The score had a maximum value of 1.0 corresponding to full health level, while lower scores, down to a minimum value of 0.0 reflected degradation in the health-related quality of life.

Time frame: At Weeks 0, 6, 12 [on the day of and the day after treatment administration (TA)], at Month 6, 9, 12, 24, at the Concluding visit (Month 30) + 6 months and +12 Months and at disease recurrence
