10. The patient has received any investigational or non-registered medicinal product other than the study medication within the 30 days preceding the first dose of study medication, or plans to receive such a drug during the study.
11. The patient has psychiatric or addictive disorders that may compromise his/her ability to give informed consent or to comply with the trial procedures.
12. The patient has other concurrent severe medical problems, unrelated to the malignancy, that would significantly limit full compliance with the study or expose the patient to unacceptable risk. For example, but not limited to: uncontrolled congestive heart failure or uncontrolled hypertension, unstable heart disease (coronary heart disease or myocardial infarction), uncontrolled arrhythmia or patients taking anticoagulant treatment or having a coagulation disorder.
13. The patient uses alternative treatments eg. plant extracts.
14. Adults under legal supervision |

E.5 End points |
E.5.1 | Primary end point(s) |
Disease-free Survival (DFS):
• Defined as the time from randomization to either the date of first recurrence of the disease or the date of death (whatever the cause), whichever occurs first.
• Types of recurrence to be considered as an event include loco-regional and distant
metastases.
• In addition, any death occurring without prior documentation of tumor recurrence will be considered as an event (and will not be censored in the statistical analysis) as this approach is less prone to introduce bias.
• If no event has occurred by the time of the analysis, then the time to event will be censored at the date of the last assessment of the patient in question.
• Any new primary cancer at another site, including transitional carcinoma of the upper urinary tract, will not be considered as recurrence and should be reported as a SAE. |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
Timepoint after randomization at which either the date of first recurrence of the disease or the date of death (whatever the cause), whichever occurs first up to a maximum of 5 years from the first administration of study treatment |
|
E.5.2 | Secondary end point(s) |
- Overall Survival.
· Defined as the interval from randomization to the date of death, irrespective of the cause of
death; patients still alive will be censored at the date of the last assessment.
- Disease-free specific survival (DFSS).
· Defined as the interval from randomization to the date of first recurrence of disease or date
of death due to bladder carcinoma, whichever occurs first. Patients without recurrence or
death are censored at the date of last assessment. Patients without recurrence who die from another cause are censored at the date of death.
- Distant metastasis-free survival (DMFS).
· Defined as the interval from randomization to the date of first distant metastasis or date of
death, whichever occurs first. Patients alive and without distant metastasis are censored at
the date of last assessment.
- Adverse events.
· Occurrence of adverse events, including potential immune-mediated diseases
- Serious adverse events.
· Occurrence of serious adverse events
- To evaluate the efficacy of the recMAGE-A3 + AS15 ASCI compared to placebo in terms of DFS separately in the population presenting the predictive gene signature, and in the population of patients who do not present this signature
- To evaluate the efficacy of the recMAGE-A3 + AS15 ASCI compared to placebo in terms of
overall survival in the overall study population, in the population of patients presenting the
predictive gene signature and in the population of patients who do not present this signature;
-To evaluate the safety in the overall study population;
- To evaluate the immune response to the recMAGE-A3 + AS15 ASCI in the overall study
population, in the population of patients presenting the predictive gene signature and in the population of patients who do not present this signature
- To evaluate Gene expression profiles of the primary tumor by microarray. |
