Summary

The purpose of this study is to describe the rate of 3-year progression free survival in men with recurrent PSA-only disease after prostatectomy, who receive combined apalutamide (ARN-509) and standard ADT with salvage radiation therapy followed by docetaxel, ADT, and apalutamide, AND who have had testosterone recovery to \>100 ng/dl at 36 months. The hypothesis is that AR inhibition with apalutamide added to standard salvage external beam radiation with androgen deprivation therapy, as well as the addition of 6 cycles of docetaxel, will further prolong progression free survival.

Conditions

Interventions

DRUG

Apalutamide

240mg tablet daily for 36 weeks

DRUG

Androgen deprivation

ADT will consist of treatment with a GnRH agonist or antagonist per physician and institutional preference. Either leuprolide acetate (Lupron Depot, 22.5 mg or 45 mg IM), triptorelin pamoate (Trelstar, 11.25 mg or 22.5 mg IM), goserelin acetate (Zoladex, 10.8mg SC) or degarelix (Firmagon 120 mg or 240 mg SC) will be administered monthly, every 3 months, or every 6 months, depending on institutional standards, for 36 weeks total.

RADIATION

Salvage radiation therapy

On week 9 (+/- 28 days), subjects will begin salvage radiation therapy to the prostate bed. The total dose to the prostate bed must be 66-74 Gy in 1.8-2 Gy daily fractions over a total of 6-8 weeks

DRUG

Docetaxel

About 4 weeks (+/- 2 weeks, pending recovery of adverse events from radiation to Grade 2 or less) after completing radiation, patients will start docetaxel 75mg/m2 intravenously, every 3 weeks for 6 cycles.
