Recruiting | Phase III 

Official Title:

A Phase 3 Study of Androgen Annihilation in High-Risk Biochemically Relapsed Prostate Cancer.

Study Purpose:

To compare progression free survival and overall survival of patients who receive the standard hormone therapy degarelix verses patients who receive degarelix and apalutamide versus patients who receive degarelix, apalutamide, abiraterone, and prednisone.


  • Hormone Therapy : DegarelixApalutamideAbiraterone + Prednisone
  • Lab Biomarker Analysis
  • Quality of Life Questionnaires
  • Arm I: Patients will receive standard of care Degarelix injections every 28 days for 13 cycles (12 months).
  • Arm II: Patients will receive Degarelix injections every 28 days and take Apalutamide orally once a day for 13 cycles (12 months).
  • Arm III: Patients will receive Degarelix injections every 28 days, take Apalutamide orally once a day, take Abiraterone orally once a day, and take prednisone once a day for 13 cycles (12 months).

After completion of study therapy, patients will have monthly labs drawn until prostate cancer is detected.  Patients will then have CT scans at that time and then have scans every 6 months.  Patients will also be followed by staff to document other anticancer treatment details and survival.

Key Participation Requirements:




19 years and older


Prostate Adenocarcinoma that is detected in the blood with a PSA doubling time of less than 9 months..


Prior therapy: radiation therapy OR not a candidate for radiation therapy

Patients are not eligible if they have evidence of metastatic cancer
