Trial design
CTIS Part I — objectives, methods, condition coding
Main objective
Scope: Diagnosis, Efficacy
To demonstrate that PSMA-flare seen 2-3weeks after initiation of ADT at baseline is
more common in bony lesions than in prostatic lesions
Secondary objectives 5
- To study if metastatic lesions with and without PSMA-flare seen in baseline behave differently in repeated 18F-PSMA-PET CT at the time of CRPC
- To compare the metastatic load seen in 18F-PSMA-PET CT and FDG-PET-CT at baseline (Sub-study 1)
- To determine the total androgen profile during the evolution of metastatic Pca by repeated total androgen measurements in every six months from diagnosis to the development of CRPC (Sub-study 2)
- To biopsy prostate lesions seen on 18F-PSMA PET and determine if the changes of PSMA uptake after ADT might have a histopathological correlation (Substudy 3)
- To investigate gut microbiome and its changes during ADT (Substudy 4)
