About

A single center, pilot trial using tamsulosin and solifenacin in 10 men with symptomatic lower urinary tract symptoms (LUTS). Subjects will be evaluated at baseline, 1, 2, and 3 months for urinary NGF, urine creatinine, NGF/CR ratio and patient reported outcomes through questionnaires.

Full description

Single center, pilot trial, single arm study using once daily dosing of tamsulosin and solifenacin in 10 men with symptomatic lower urinary tract symptoms (LUTS). Assessments occur at Baseline, 1 Month, 2 Month and 3 Month to evaluate: urinary NGF (pg/mL), urine creatinine (mg/dL), NGF/Cr ratio and patient reported questionnaire outcomes (AUA Symptom Score/IPSS, Patient Perception of Bladder Condition, Patient Perception of Urge Intensity 'PPIUS', LUTS Urinary Symptoms and Quality of Life). Each participant is assessed from baseline to Month 3 measurements. Protection of human subjects will be provided through the Houston Methodist Research Institute Institutional Review Board (see appendix 2). All men will receive morning dosing with Tamsulosin 0.4 mg (1 tab) and Solifenacin 5 mg (1 tab) orally at the same time.
