Outcomes

Primary Outcome Measures

One-year Overall Survival Rate (OSR) Estimated by Complete Case Method

The 1-year overall survival rate (OSR) in the GS+ Population would be above 50% (target = 71%), a percentage which was reported together with its 95% confidence interval (CI). Maximum 1-year OSR of any currently available treatment in the MAGE-A3-positive population = 50% (P0). This median OS of 12 months is based on the observed median OS for MAGE-A3-positive patients, whose tumor did not present the predictive GS. The target 1-year OSR for patients presenting the predictive GS = 71% (P1). This corresponds to a median OS of 24 months when assuming an exponential distribution of OS.

Number of Patients Reported With Serious Adverse Events (SAEs)

Serious adverse events (SAEs) assessed included medical occurrences that result in death, are life threatening, require hospitalization or prolongation of hospitalization or result in disability/ incapacity. Events which were part of the natural course of the disease under study (i.e., disease progression, recurrence) were captured as part of the clinical activity outcome variables in this study; therefore these did not need to be reported as SAEs. Progression/recurrence of the tumor in a patient was recorded as part of the clinical assessment data collection, and deaths due to progressive disease was recorded on a specific form, but not as an SAE. However, if the investigator considered that there was a causal relationship between treatment or protocol design/procedures and the disease progression/recurrence, then the event was reported as an SAE. Any new primary cancer (non-related to the cancer under study) was reported as an SAE.

Secondary Outcome Measures

Number of Patients With Diseases Characteristics by GS

Cancer staging (characteristics and categories) as by the categorization by the American Joint Committee on Cancer (AJCC) Staging Manual 2002: "Stage IIIA patients have up to three microscopic nodal metastases arising from a non-ulcerating primary melanoma and have an ' intermediate risk' for distant metastases and melanom-specific survival. Stage IIIB patients have up to three microscopic nodal metastases arising from a non-ulcerating melanoma or have up to three microscopic nodal metastases arising from an ulcerating melanoma, or have intralymphatic metastases without nodal metastases. They constitute a 'high-risk' group prognostically." The remaining patients with regional melanoma are Stage IIIC patients are at 'very high risk' for distant metastases and melanoma-specific mortality. Stage IV melanoma patients have metastasis at any distant site and constitute the group with the worst prognosis. Stage MC patients are those with confirmed missing cancer.

Progression-free Survival (PFS) by GS

From study start (Month 0) to Month 24, each patient was censored out of the analysis at 1st report of disease progression or death. PFS was defined and calculated as the time from first treatment to either the first progression of the disease or the date of death, whichever occurred first. In case a patient went off protocol treatment, the date of first documented progression (if applicable) was to be used as date of progression. Patients still alive with no evidence of disease progression at the time of their last visit or for whom date of first documented progression was not applicable, were censored at the time of the last examination. PFS analysis was performed using the non-parametric Kaplan-Meier method.

Kaplan-Meier Estimates of the Progression-free Survival (PFS) at Months 6, 12 and 24, by Gene Signature

PFS was defined as the time from the date of registration of the patient to either the date of disease progression or the date of death, whichever comes first. Patients alive and without disease progression were censored at the date of their last tumor evaluation. The PFS estimates were assessed by the Kaplan-Meier method and expressed as the percentage of patients who did not progress and were alive at a given time.

Overall Survival (OS) by GS

OS was defined as the time from registration of the patient until death, with patients alive at the time of analysis censored at the time of the last contact.

Time to Treatment Failure (TTF) by GS

The TTF was defined as the time from registration of the patient until the date of the last treatment administration, irrespective of the reason for study treatment discontinuation.

Best Overall Response (BOR) by GS

The BOR was the best response recorded from the start of the treatment until disease progression/ recurrence, except for confirmed objective response, which was reported as BOR independently of its time of occurrence. Per Response Evaluation Criteria In Solid Tumors Criteria (RECIST v1.0) for target lesions and assessed by MRI and/or CT: Complete Response (CR), Disappearance of all target lesions; Partial Response (PR), >=30% decrease in the sum of the longest diameter of target lesions without any new lesions and/or progression of existing non-target lesions; Stable Disease (SD), neither sufficient shrinkage to qualify for a Partial Response nor sufficient increase to qualify for Progression of Disease (PD) without any new lesions and/or progression of existing non-target lesions; PD, >=20% increase in the sum of the longest diameter of target lesions, or a measurable increase in a non-target lesion, or the appearance of new lesions; NE = Non-evaluable response.

Duration of Response (CR or PR)

Duration of response was measured from the time when the measurement criteria for CR/ PR (whichever was recorded first) were met until the first date that recurrent or PD was objectively documented (taking as reference for PD the smallest measurements recorded since the treatment started). Note: As there was only one patient analysed in the GSK2132231A GS- Group, the median duration of response was not calculated for this latter group.

Duration of Stable Disease (SD), or Time-to-Progression (TTP) by GS

The duration of stable disease (SD), or TTP, was tabulated for patients whose best response was SD. The minimal time interval required between 2 measurements for determination of SD was 12 weeks.

Concentrations of Antibodies Against Protein D (Anti-PD)

Anti-MAGE-A3 Antibody Response

Anti-MAGE-A3 antibody 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.

Anti-PD Antibody Response

Anti-PD antibody response defined as: For initially seronegative patients: post-vaccination antibody concentration ≥ 100 EL.U/mL; For initially seropositive patients: post-vaccination antibody concentration ≥ 2 fold the pre-vaccination antibody concentration.

Brief Summary

The objective of this study is to evaluate the clinical activity of the GSK2132231A immunotherapeutic in patients with MAGE-A3 positive unresectable metastatic melanoma presenting with the predictive gene signature.

Detailed Description

In this study, patients were to receive a maximum of 24 doses of recMAGE-A3 + AS15 according four cycles over a period of four years. An active follow-phase (up to five years after registration into the study) was planned for all patients. As of Amendment 2, there will no longer be an active follow-up of patients after discontinuation or completion of the treatment. The study will end approximately 30 days after the last dose will be administered. In addition, no more biological samples will be collected for protocol research purposes. For each biological sample already collected in the scope of this study and not tested yet, testing will not be performed by default, except if a scientific rationale remains relevant. Blood sampling for safety monitoring as per protocol will continue.
