Main objective

Scope: Safety, Efficacy

To compare the efficacy of individualized PSMA PET/CT targeted treatment compared with conventional "salvage" radiotherapy in patients with biochemical recurrence after prostate cancer surgery. Main objective PSA progression free survival

Secondary objectives 5

  1. In the context of PSMA PET/CT individualized treatment vs. conventional "salvage" radiotherapy, compare quality of life outcomes
  2. In the context of PSMA PET/CT individualized treatment vs. conventional "salvage" radiotherapy, compare time to secondary treatment
  3. In the context of PSMA PET/CT individualized treatment vs. conventional "salvage" radiotherapy, compare time to metastatis
  4. In the context of PSMA PET/CT individualized treatment vs. conventional "salvage" radiotherapy, compare overall and cancer specific survival
  5. In the context of PSMA PET/CT individualized treatment vs. conventional "salvage" radiotherapy, compare health economics

1 Randomisation
With randomization 1:2; 1/3=33.3% of all patients till be randomized to control arm and 2/3=66.7% of all patients will be randomized to experimental arm. Control arm will receive conventional SRT. Experimental arm will receive individual treatment based on results of PSMA PET/CT.

Eligibility criteria

Principal inclusion / exclusion criteria as submitted by sponsor

Inclusion criteria 3

  1. Patients previously treated for prostate cancer with radical prostatectomy and now having a biochemical recurrence (BCR) defined as: PSA >0.2 <2.0 ng/mL, and increasing measured twice.
  2. Multidisciplinary conference (MDK) decision to offer the patient salvage radiotherapy (SRT).
  3. Signed Informed Consent

Exclusion criteria 4

  1. Previous prostate cancer with biochemical recurrence
  2. Previous treatment with ADT after surgery
  3. Previous pelvic radiotherapy
  4. Patients with positive lymph nodes at surgery

Endpoints

Primary and secondary outcome measures (English text)

Primary endpoints 1

  1. Primary PSA progression free survival (PFS) defined as documented biological progression: No response to SRT: the PSA value 3 months after completion of SRT is ≥ 0.1 ng/mL higher than the PSA value just before radiotherapy. Progression after initial response to SRT: Two rising PSA values ≥ 0.1 ng/mL after completion of radiotherapy, with the last value ≥ 0.2 ng/mL.

Secondary endpoints 5

  1. Time to metastasis
  2. Prostate cancer specific survival
  3. Overall survival
  4. Time to secondary treatment: Time from randomization to start of secondary treatment, usually hormonal treatment
  5. Quality of life: All patients fill in PSMA-PROM, a study modified quality of life questionnaire developed by the National PCa Register at baseline and 6, 12, 36, and 60 months after completed treatment.
