- 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)
- Serum PSA levels:
- ≥2 ng/mL and ≤20ng/mL for primary radiotherapy patients
- ≥0.4 ng/ml and ≤10ng/ml for radical prostatectomy with or without salvage radiotherapy patients
- PSADT >3 months and ≤24 months

- No evidence of local recurrence in radical prostatectomy or salvage radiotherapy patients
- Expected survival ≥2 years
- Eastern Cooperative Oncology Group (ECOG) performance status 0, 1 or 2 (see Appendix 1) Miscellaneous:
- Able to swallow and retain oral medication
- Able and willing to participate in the full 2 years of the study
- Able to read and write (the MAX-PC questionnaire is self-administered), understand instructions related to study procedures and give written informed consent
- In France, a patient will be eligible for inclusion in this study only if either affiliated to or a beneficiary of a social security category.
- Any unstable serious co-existing medical condition(s) including but not limited to myocardial infarction, coronary bypass surgery, unstable angina, cardiac arrhythmias, clinically evident congestive heart failure or cerebrovascular accident within 6 months prior to Visit 1, or uncontrolled diabetes or peptic ulcer disease which is uncontrolled by medical management
- Abnormal liver function tests (greater than 2 times the upper limit of normal [ULN] for alanine aminotransferase [ALT], aspartate aminotransferase [AST] or alkaline phosphatase [ALP] or >1.5 x ULN for bilirubin).
- Serum creatinine >1.5 x ULN
- History of another malignancy within 5 years that could affect the diagnosis of prostate cancer
- History or current evidence of drug or alcohol abuse within 12 months prior to Visit 1

- Known hypersensitivity to any 5-AR inhibitor or to any drug chemically related to dutasteride Disease characteristics:
- Serum PSA levels
- >20 ng/mL in primary radiotherapy patients
- >10 ng/mL in radical prostatectomy with or without salvage radiotherapy patients
