Trial overview
Official title: A Randomised, Double-Blind, Placebo-Controlled Trial Assessing the Efficacy and Safety of Dutasteride (AVODART™) 0.5 mg in Extending the Time to PSA Doubling in Men with Prostate Cancer and Biochemical Failure (PSA increase) after Radical Therapy with Curative Intent
Trial description: ARI109924 will be a 2-year, multicentre, randomised, double-blind, placebo-controlled trial assessing the efficacy and safety of dutasteride in extending time to prostate specific antigen (PSA) doubling in men who have been treated for clinically localised prostate cancer (PCa) with a radical therapy (radical prostatectomy, primary radiotherapy or salvage radiotherapy) with curative intent but who experience a biochemical failure (PSA rise) afterwards without signs or symptoms of metastases.

Inclusion and exclusion criteria
Inclusion criteria:
- Patients eligible for enrolment in the study must meet all of the following criteria:
- Males <85 years of age

- Time from radiotherapy should be at least 1 year from termination of radiotherapy treatment
- After radical prostatectomy with or without salvage radiotherapy:
- 3 rises in PSA level from nadir PSA, with each determination at least 4 weeks apart and each PSA level ≥0.2 ng/mL and a final PSA level ≥0.4 ng/mL (nadir PSA is defined as the lowest PSA value achieved after therapy)
