A Phase II, Randomized, Three-Arm Study of Abiraterone Acetate Alone, Abiraterone Acetate Plus Degarelix, a GnRH Antagonist, and Degarelix Alone for Patients with Prostate Cancer with a Rising PSA and Nodal Disease Following Definitive Radical Prostatectomy

The primary endpoint for each cohort is progression-free survival (PFS) at 18 months from the start of randomization (PSA0). PFS is defined as an undetectable (less than or equal to 0.05 ng/mL) PSA with a non-castrate level of testosterone (greater than 150 ng/dL). Pathological lymph nodes (whether target or non-target) must also have reduction in short axis to less than 10mm (Compelte Response per RECIST) in order to meet the criteria for PFS.
Secondary endpoints: (1) PSA response rate (Percentage of patients with an undetectable PSA at 8 months from PSA0). (2) Effects of each arm on overall quality of life, with particular attention to libido, potency, anxiety, depression, hot flashes and fatigue. (3) Frequency and intensity of non-hematologic adverse events. (4) Testosterone and leuteinizing hormone (LH) recovery rates.
Tertiary endpoint: Correlative tissue analysis with clinical outcomes while on study treatment.
