About this trial

The aim is to investigate whether the addition of short-term androgen deprivation therapy (ADT) during 1 month or short-term ADT during 6 months together with an androgen receptor targeted therapy (ARTA) to metastasis-directed therapy (MDT) significantly prolongs poly-metastatic free survival (PMFS) and/or metastatic castration-refractory prostate cancer free survival (mCRPC-FS) in patients with oligorecurrent hormone sensitive prostate cancer.

Eligibility criteria

Qualifiers

Histologically proven initial diagnosis of prostate adenocarcinoma

Priory treated and controlled primary tumor

Biochemical recurrence defined by prostate-specific antigen (PSA) values >0,2 ng/ml (i.e., two consecutive increases) following radical prostatectomy + postoperative radiotherapy and a PSA value of 2 ng/ml above the nadir after high-dose RT.

Oligorecurrent disease defined as a maximum of 5 extracranial metastases in any organ, diagnosed on PSMA PET-CT or PSMA PET-MRI reported according to the E-PSMA consensus guidelines for interpretation of PSMA-PET (26). Nodal (N1) disease can be included only when accompanied by M1a-c disease, provided that the total number of spots does not exceed 5.

Disqualifiers

Any disorder, which in the Investigator's opinion might jeopardise the participant's safety or compliance with the protocol

Any prior or concomitant treatment(s) that might jeopardise the participant's safety or that would compromise the integrity of the Trial

Participation in an interventional Trial with an investigational medicinal product (IMP) or device

Serum testosterone level at castration level.
