E.5 End points |
E.5.1 | Primary end point(s) |
The objective metabolic response according to PERCIST criteria (Haroche, et al. 2015) is defined by the PET response and will be used to evaluate the overall therapeutic response at month 3 (W12).
|
La réponse métabolique objective selon les critères PERCIST (Haroche, et al. 2015) est définie sur la TEP et sera utilisée pour évaluer la réponse thérapeutique globale au troisième mois (W12).
|
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
For PERCIST criteria, a quantitative analysis of uptake will be performed using the standard uptake value (SUV). Fitting regions of interest covering pathologic uptake will be used to define target lesions. PERCIST will be used to classify the patients as complete metabolic response, partial metabolic response (reduction of a minimum of 30% in target lesions), stable metabolic disease or progressive metabolic disease.
|
Pour les critères PERCIST, une analyse quantitative de l'absorption sera réalisée à l'aide des SUV (standard uptake value ). Les régions d’intérêt seront utilisées pour définir les lésions cibles. PERCIST sera utilisé pour classer les patients en réponse métabolique complète, en réponse métabolique partielle (réduction d'au moins 30% des lésions cibles), en maladie métabolique stable ou en maladie métabolique progressive.
|
|
E.5.2 | Secondary end point(s) |
The secondary endpoints include overall survival, progression-free survival as assessed with PERCIST criteria (defined as the time between the date of randomization and the first documented event of disease progression or death), duration of response and safety. Tumor assessments will be carried out at baseline and every 12 weeks. |
Les critères secondaires incluent la survie globale, la survie sans progression évaluée par les critères PERCIST (définis comme le temps écoulé entre la date de randomisation et le premier événement documenté de progression ou de décès de la maladie), la durée de la réponse et la sécurité. Des évaluations de tumeurs seront effectuées au départ et toutes les 12 semaines. |
