Summary
Brief summary (as posted)
This is an investigator-initiated phase II single arm trial, combining neoadjuvant apalutamide (ARN509) with radical prostatectomy, in the treatment of D'Amico intermediate to high risk organ-confined prostate cancer. Apalutamide has shown efficacy in castrate resistant prostate cancer in phase II studies and are now in phase III trials combined with radiation in organ confined disease. The primary study objectives include assessment of (i) oncological efficacy as determined by tumour downstaging and achievement of nadir PSA The secondary study objectives include(i) determination of adverse effects related to apalutamide and surgical complication rates (ii) human prostate tissue effect of apalutamide The study will recruit thirty eligible participants who will receive 12 weeks of oral apalutamide 240mg daily. This will be followed by standard-of-care radical prostatectomy. The total trial duration is 26 weeks.
