Phase III Randomized Trial of 68Ga-PSMA-11 PET/CT Molecular Imaging for Prostate Cancer Salvage Radiotherapy Planning [PSMA-SRT]

Condition: Recurrent Prostate Carcinoma


  • Drug: 68Ga-PSMA-11

Purpose: To evaluate the success rate of salvage radiation therapy (SRT) for recurrence of prostate cancer after prostatectomy with and without planning based on 68Ga-PSMA-11 PET/CT.

Study Type: Interventional

Sponsor: Jonsson Comprehensive Cancer Center

Primary Outcome Measures:

  • Measure: Rate of biochemical progression-free survival
  • Time Frame: Time Frame: From date of initiation of salvage radiation therapy until the date of first documented progression or date of death from any cause, whichever came first, assessed up to 5 years
  • Safety Issue:

Secondary Outcome Measures:

  • Measure: 5-year progression-free survival rate
  • Time Frame: 5 years
  • Safety Issue:
  • Measure: Metastasis free-survival
  • Time Frame: 5 years
  • Safety Issue:
  • Measure: Rate of additional prostate cancer therapy initiation-free survival
  • Time Frame: assessed up to 5 years
  • Safety Issue:

Estimated Enrollment: 193

Study Start Date: July 12, 2018
