The dose-limiting toxicities (DLT) were defined as follows: •An Antigen-Specific Cancer Immunotherapeutic (ASCI) related or possibly ASCI related grade 3 or higher toxicity. Grade 3 myalgia, arthralgia, headache, fever, rigors/chills and fatigue (including lethargy, malaise and asthenia) persisting for 48 hours despite therapy. •An ASCI related or possibly ASCI related grade 2 or higher allergic reaction occurring within 24 hours following the ASCI administration. •An ASCI related or possibly ASCI related decrease in renal function, with a creatinine clearance lower than (\<) 40 milliliters per minute (mL/min). •An ASCI-related or possibly ASCI-related symptomatic and confirmed adrenal insufficiency. The grading used was defined according to the Common Terminology Criteria for Adverse Events (CTCAE) version 4.0: Grade 3 DLT = severe DLT. Related = DLT considered by investigator as possibly related to product administration.
A seronegative/seropositive patient for anti-PRAME antibodies was a patient with antibody concentration lower (\<)/ higher than or equal to (≥) cut-off level. Humoral immune response was defined as a) if baseline concentration \< cut-off level: post treatment concentration ≥ cut-off level, or b) if baseline concentration ≥ cut-off level: post treatment concentration at least twice the baseline value. Cut-off values for seropositivity (by enzyme-linked immunosorbent assay \[ELISA\]) were 12 ELISA Units per milliliter (EL.U/mL).
The best overall response is the best response recorded from the start of the treatment until disease progression (taking as reference for progressive disease the smallest measurements recorded since the treatment started). In general the patient's best response assignment depended on the achievement of both measurement and confirmation criteria. The best overall response includes the complete response (CR) defined as disappearance of all targeted/non-targeted lesions and partial response (PR) defined as at least 30% decrease in the sum of longest diameter (LD) of target lesions taking as reference the baseline sum LD and persistence of one or more non-targeted lesion(s).

| GSK2302025A Cohort 1 | EXPERIMENTAL | Male or female patients with histologically proven cutaneous melanoma received the investigational Low-Dose (LD) adjuvanted GSK2302025A immunotherapeutic vaccine, intramuscularly into the deltoid or lateral region of the thigh, with alternation on right or left side at each succeeding injection. Subjects received a total of 24 administrations in 4 cycles: 6 administrations given at 2 weeks intervals in cycle 1, 6 administrations given at 3 weeks intervals in cycle 2, 4 administrations given at 6 weeks intervals in cycle 3 and 4 administrations given at 3 months interval in cycle 4. |
| GSK2302025A Cohort 2 | EXPERIMENTAL | Male or female patients with histologically proven cutaneous melanoma received the investigational Middle-Dose (MD) adjuvanted GSK2302025A immunotherapeutic vaccine, intramuscularly into the deltoid or lateral region of the thigh, with alternation on right or left side at each succeeding injection. Subjects received a total of 24 administrations in 4 cycles: 6 administrations given at 2 weeks intervals in cycle 1, 6 administrations given at 3 weeks intervals in cycle 2, 4 administrations given at 6 weeks intervals in cycle 3 and 4 administrations given at 3 months interval in cycle 4. |
| GSK2302025A Cohort 3 | EXPERIMENTAL | Male or female patients with histologically proven cutaneous melanoma received the investigational High-Dose (HD) adjuvanted GSK2302025A immunotherapeutic vaccine, intramuscularly into the deltoid or lateral region of the thigh, with alternation on right or left side at each succeeding injection. Subjects received a total of 24 administrations in 4 cycles: 6 administrations given at 2 weeks intervals in cycle 1, 6 administrations given at 3 weeks intervals in cycle 2, 4 administrations given at 6 weeks intervals in cycle 3 and 4 administrations given at 3 months interval in cycle 4. |
| GSK2302025A Cohort 4 | EXPERIMENTAL | In Phase 2 of the study subjects received the optimal investigational dose-level identified in Phase 1. Patients received a treatment consisting of 24 injections of the experimental GSK2302025A immunotherapeutic. |
