Design outcomes

Primary

MeasureTime frame
Main Objective: The primary objective of this study is to determine the diagnostic accuracy of the primary PET measure, to predict clinical response in patients with mCRPC treated with cabazitaxel. ;Secondary Objective: 1) To determine the predictive value of alternative quantitative PET measures, including alternative standardized uptake values (SUV), metabolic volume, single lesion versus multiple lesion approach and interlesional concordance (heterogeneity) of PET signal changes. 2) To describe the toxic effects of cabazitaxel in terms of serious adverse events (with reference to CTCAE 4.03 criteria) irrespective of treatment relationship, of as well as cumulative administered cabazitaxel dose. ;Primary end point(s): The main endpoint of this study is the diagnostic accuracy of the PET measures (as defined by PERCIST, using SUVidif with peak VOI) to predict clinical response at 3 and 6 months of treatment respectively, described as sensitivity, specificity, positive and negative predictive values, respectively. ;Timepoint(s) of evaluation of this end point: After 3 and 6 cycles after the start of cabazitaxel.

Secondary

MeasureTime frame
Secondary end point(s): The secondary endpoints of this study are: - predictive value of changes of o alternative standardized uptake values (as described by Verwer et al. [11]) o choline avid tumour volume (volume of lesion, defined using PET-based VOIs [17]) - impact of lesion selection on predictive value o single lesion versus multiple lesion approach (according to PERCIST [7]) - interlesional concordance (heterogeneity) of PET signal changes - serious adverse events (with reference to CTCAE 4.03 criteria) irrespective of treatment relationship - cumulative administered dose of cabazitaxel ;Timepoint(s) of evaluation of this end point: After 3 and 6 cycles after the start of cabazitaxel.
