Patients who demonstrate clinical evidence of failure after treatment with Finasteride for 12 or more months. Failure includes one or more of the following: (i) AUA SS \\> 10; (ii) Q-max \\< 10 cc/sec; (iii) Post void residual volume (PVR) \\>200cc.\n2. Patients who remain subjectively symptomatic of LUTS secondary to BPH after treatment with Finasteride for at least six months.\n\nExclusion Criteria Patients with Neurogenic Bladder/LUTS secondary to neurologic disease Patients with the diagnosis of prostate cancer Patients with an allergy to Finasteride/Dutasteride\n\nSTUDY DESIGN AND DURATION:\n\nThis will be a single institution, open label pilot study involving 26 patients over 18-24 months. Each patient will be treated with the standard dose of Dutasteride for at least twelve months and followed for an additional 12 months.\n\nEFFICACY AND SAFETY MEASUREMENTS:\n\nImprovement in flowmetry, AUASS and PVR will be the primary outcome measures of efficacy. Quality of life measurement will be made also. The exploratory measures will include PSA and prostate volume. All adverse events including tolerability of the test agent will be recorded.\n\nSUMMARY:\n\nA positive result showing objective (AUASS, Q-max, PVR) and subjective (satisfaction index) improvement in these previously treated patients should engender interest in a multicenter study to confirm our data. The clinical import is that this population should be switched to Dutasteride without prolonged treatment with Finasteride for no additional benefit to the patient. A failure of treatment with one hormonal agent does not necessarily imply a lack of response to another agent of the same class.'}, 'eligibilityModule': {'sex': 'MALE', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'minimumAge': '50 Years', 'healthyVolunteers': True, 'eligibilityCriteria': 'Inclusion Criteria:\n\n1.
