Arm Intervention/treatment
Experimental: MAGE-A3 Group

Study products were administered as intramuscular (IM) injections in the deltoid or the lateral region of the thigh (not in anatomical regions where lymph nodes had been excised): 5 doses of ASCI product at 3-week intervals, followed by 8 doses of ASCI product at 12-week intervals.
Drug: GSK 2132231A
IM solution, a course of 13 injections administered over 27 months

Placebo Comparator: Placebo Group
Patients who received up to 13 doses of placebo. Study products were administered as intramuscular (IM) injections in the deltoid or the lateral region of the thigh (not in anatomical regions where lymph nodes had been excised): 5 doses of placebo at 3-week intervals, followed by 8 doses of placebo at 12-week intervals.
Drug: Placebo
IM solution, a course of 13 injections administered over 27 months




Primary Outcome Measures :
  1. Disease Free Survival (DFS) [ Time Frame: At Final analysis (Month 30 = Year 2.5) ]
    DFS = time 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 sum of follow-up periods, in years, 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).

  2. Disease Free Survival (DFS) [ Time Frame: At follow-up analysis (up to Year 5) ]
    DFS = time 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 sum of follow-up periods, in years, 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).


Secondary Outcome Measures :
  1. Overall Survival (OS) [ Time Frame: At Final analysis (Month 30 = Year 2.5) and at follow-up analysis (up to Year 5) ]
    Overall Survival (OS) was defined as the interval from randomization to the date of death, irrespective of the cause of death. OS was expressed as the sum of follow-up periods, in years, until the occurrence of death.

  2. Disease-free Specific Survival (DFSS) [ Time Frame: At Final analysis (Month 30 = Year 2.5) ]
    Disease Free Specific Survival (DFSS) was defined as the interval 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 sum of follow-up periods, in years, 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).

  3. Distant Metastasis-free Survival (DMFS) [ Time Frame: At Final analysis (Month 30 = Year 2.5) ]
    Distant Metastasis Free Survival (DMFS) was defined as the interval from randomization to the date of first distant metastasis or date of death, whichever occurred first. DMFS was expressed as the sum of follow-up periods, in years, 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).

  4. 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 ]
    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.

  5. Number of Subjects With Anti-MAGE-A3 Antibody Concentrations Above the Cut-off Value [ Time Frame: At Weeks 0, 6, 12, 36, 48 72, 120 (Concluding visit) and at Week 120 + 6 months ]
    The cut-off value was 27 Enzyme-Linked Immunosorbent Assay (ELISA) units per milliliter (EL.U/mL).

  6. Anti-MAGE-A3 Antibody Geometric Mean Concentrations [ Time Frame: At Weeks 0, 6, 12, 36, 48 72, 120 (Concluding visit) and at Month 120 + 6 months ]
    Anti-MAGE-A3 antibody concentrations were presented as geometric mean concentrations (GMC) and expressed in EL.U/mL.

  7. Number of Subjects With Anti-MAGE-A3 Antibody Response [ Time Frame: At Weeks 0, 6, 12, 36, 48 72, 120 (Concluding visit) and at Month 120 + 6 months ]
    Treatment response defined as: - For initially seronegative patients: post-vaccination antibody concentration ≥ 27 EL.U/mL; - For initially seropositive patients: post-vaccination antibody concentration ≥ 2 fold the pre-vaccination antibody concentration.

  8. Number of Subjects With Abnormal Haematological and Biochemical Parameters [ Time Frame: Within the 31-day (Days 0-30) post-vaccination period, at follow-up analysis ]
    Laboratory abnormalities belong to hematological and biochemical parameters such as: alanine aminotransferase [ALT], asparatate aminostransferase [AST], alkaline phoshatase [AP], bilirubin [BIL], creatinine [CREA], hemoglobin [HGB], leukocytes [LEU], lymphopenia [LYMPH], neutrophils [NEU], platelets [PLA]. Parameter grades (Grade [G] 0, 1, 2, 3, 4, Unknown) were compared to each baseline parameter grade (G Unknown, 0, 1, 2, 3), as defined by the Common Terminology Criteria for Adverse Events (CTCAE), version 3.0 of August 9, 2006.

  9. Number of Subjects With Any Adverse Events (AEs) [ Time Frame: Within the 31-day (Days 0-30) follow-up period after vaccination - at Follow-up analysis ]
    An unsolicited AE covers any untoward medical occurrence in a clinical investigation subject temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product and reported in addition to those solicited during the clinical study and any solicited symptom with onset outside the specified period of follow-up for solicited symptoms. Any was defined as the occurrence of any unsolicited AE regardless of intensity grade or relation to vaccination.

  10. Number of Subjects With Any Serious Adverse Events (SAEs) [ Time Frame: From Day 0 up to study end (Year 5) ]
    Serious adverse events (SAEs) assessed include medical occurrences that result in death, are life-threatening, require hospitalization or prolongation of hospitalization or result in disability/incapacity.

  11. Number of Subjects With Potential Immune-mediated Diseases (pIMDs) [ Time Frame: Within the 31-day (Days 0-30) post-administration period, at Follow-up analysis ]
    Potential immune-mediated diseases (pIMDs) are a subset of AEs that include autoimmune diseases and other inflammatory and/or neurologic disorders of interest which may or may not have an autoimmune aetiology.
