E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The clinical trial’s objective is to estimate the proportion of patients with PSA progression within two years after randomization. |
Cílem klinického hodnocení je odhad podílu pacientů, u kterých dojde k PSA progresi do dvou let po randomizaci. |
|
E.2.2 | Secondary objectives of the trial |
The clinical trial’s objective is to estimate the proportion of patients with a disease progression within two years of randomization, quality of life and the influence on the pain scale scoring using the standardized EORTC QLQ-C30 (v3.0) questionnaire, the incidence of adverse events and overall survival.
An exploratory objective is to search for potential biomarkers that could play role as prognostic factors, indicate the biological effect of ACI on immune-response or identify a subgroup of patients profiting from cancer immunotherapy based on gene expression profiling. |
Cílem klinického hodnocení je odhad podílu pacientů s progresí onemocnění do dvou let od randomizace, hodnocení kvality života a ovlivnění škály bolesti za použití standardizovaného dotazníku EORTC QLQ-C30 (v3.0), četnost výskytu nežádoucích příhod a celkové doby přežití.
Explorativním cílem je definovat potenciální biomarkery, které by mohly hrát roli jako prognostické faktory, indikovat biologický vliv ACI na imunitní odpověď nebo umožnit identifikaci subpopulací pacientů profitujících z protinádorové imunoterapie (profilování na základě genové exprese). |

Definition of the end of the trial and justification where it is not the last
visit of the last subject undergoing the trial
|
The main part of the study will be terminated by the Sponsor as soon as the last patient undergoes the EOS visit. However, the study and collection of PSA and survival data (i.e. PSA and survival follow-up) will continue until sufficient data to evaluate overall survival are available. The current estimate is that the data will be available approximately 2 years after the EOS visit of the last patient. |
