Study Details

Study Description

Brief Summary

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.

Condition or Disease Intervention/Treatment Phase
Phase 4

Detailed 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.

  • Outcome Measures

    Primary Outcome Measures

    1. Change in Urinary Nerve Growth Factor (pg/mL) at Baseline Compared to Post Dose Exposure at Mo.3/Wk12 [Change from baseline to week 12 (3 months)]

      Urine sample tested for urinary Nerve Growth Factor (uNGF as measured in pg/mL), a small secreted protein in the bladder that supports bladder function regulation, at baseline (pre-dose) and week 12/Month 3 post-dose, after using daily tamsulosin and solifenacin.

    2. Change From Baseline in Urinary Growth Factor to Creatinine Ratio (GF/Cr) [change from baseline score to Month 3]

      The urinary growth factor (GF) to creatinine ratio may be potential biomarker for overactive bladder, based on published articles. Measuring the ratio at baseline and Month 3, comparing the difference after treatment with tamsulosin and solifenacin which may provide insight into how lower urinary tract symptoms in men progresses.

    Secondary Outcome Measures

    1. Change in Post Void Residual (mL) at Baseline Compared to Post Dose Exposure at Mo.1, Mo, 2, and Mo. 3/Wk12 [Change from baseline to months 1, 2 and 3]

      Urine sample tested for urinary post void residual (measured in mL) at baseline (pre-dose), Month 1 and Month 2and week 12/Month 3 post-dose, post dose w/tamsulosin and solifenacin.

    2. Change in Maximum Urinary Flow Rate (ml/s) at Baseline Compared to Post Dose Exposure at Mo.1, Mo, 2, and Mo. 3/Wk12 [Change from baseline to months 1, 2 and 3]

      Urination flow rate (measured in milliliters per second) at baseline (pre-dose), and Month 1, Month 2, and Month 3/Week 12 pose-dosing with tamsulosin and solifenacin. An average maximum urinary flow rate in males is 21 ml/sec aged 14-45 years-old and 12 ml/sec in males aged 46-65 years-old.

    3. Change in IPSS-International Prostate Score Scale at Baseline Compared to Post Dose Survey at Month 1, 2, and Month 3/Week12. [Change from baseline to months 1, 2 and 3]

      The survey, IPSS-International Prostate Score Scale, survey responses measured 0-35, is collected at baseline compared to post dose survey response at Month 1, Month 2, and Month 3/Week12 post-dose. The lower the score is indicative of less or fewer urinary symptoms while 35 is consistent with more bothersome symptoms.

    4. Change in PPUS-Patient Perception of Urinary Urgency Survey Score at Baseline Compared to Post Dose Exposure at Mo.1, Mo, 2, and Mo. 3/Wk12 [Change from baseline to months 1, 2 and 3]

      The Patient Perception of Urinary Urgency self administered survey score has a maximum score 4, zero to four, for how severe a patient describes their urinary voiding frequency. Four is the most bothersome score, 0 or 1 is the least bothersome. Pre-dose / baseline score is compared at Month 1, Month 2, and Month 3, after dosing with tamsulosin and solifenacin.

    5. Change in PBC-Patient Perception of Bladder Condition at Baseline Compared to Post Dose Exposure at Mo.1, Mo, 2, and Mo. 3/Wk12 [Change from baseline to months 1, 2 and 3]

      Change in the Perception of Bladder through a self administered survey at baseline compared to Month 1, Month 2, and Month 3, following exposure to tamsulosin and solifenacin. The survey score measures from zero to 6, with 6 being the most bothersome bladder symptoms and 0 to 1 being the least bothersome.

    6. Change in ICIQ-MLUTS - International Consultation on Incontinence Modular Questionnaire for Male LUTS Baseline Compared to Post Dose Exposure at Mo.1, Mo, 2, and Mo. 3/Wk12 [Change from baseline to months 1, 2 and 3]

      Measuring change in the International Consultation on Incontinence Modular Questionnaire for male lower urinary tract symptoms through a self administered survey at baseline compared to Month 1, Month 2, and Month 3, after exposure to tamsulosin and solifenacin. The survey score is a zero to 182 range with 182 being the most bothersome and zero to one being the least bothersome.

    7. Change in ICIQ LUTS QoL -International Consultation on Incontinence Modular Questionnaire LUTS Quality of Life for Male LUTS Baseline Compared to Post Dose Exposure at Mo.1, Mo, 2, and Mo. 3/Wk12 [Change from baseline to months 1, 2 and 3]

      Change in the International Consultation on Incontinence Modular Questionnaire on lower urinary tract symptoms quality of life survey for men, self administered, compared to Month 1, Month 2, and Month 3, after exposure to tamsulosin and solifenacin. The survey scoring is zero to 182, with 182 being the most bothersome and 0 to 1 being the least bothersome.

    8. Change in Urinary Nerve Growth Factor (pg/mL) at Baseline Compared to Post Dose Exposure at Mo.1/Wk4 and Mo.2/Wk8 [Change from baseline to Mo.1/Wk4 and Mo.2/Wk8]

      Urine sample tested for urinary Nerve Growth Factor (uNGF as measured in pg/mL), a small secreted protein in the bladder that supports bladder function regulation, at baseline (pre-dose) compared to Month 1/Week 4 and Month 2/Week 8, post dosing with tamsulosin and solifenacin.

    9. Change in Urinary Growth Factor to Creatinine Ratio (GF/Cr) From Baseline Compared to Month 1/Week4 and Month 2/Week 8. [change from baseline score to Mo.1/Wk4 and Mo.2/Wk8 scores]

      Assessing the change from baseline to Month 1/Week 4 and Month 2/Week 8, of the urinary growth factor (GF) to creatinine ratio in men, which may be potential biomarker for overactive bladder, based on published articles. Measuring the ratio at baseline compared to Month 1 and Month 2 may provide insight into how lower urinary tract symptoms in men progresses.

    Title Change in Urinary Growth Factor to Creatinine Ratio (GF/Cr) From Baseline Compared to Month 1/Week4 and Month 2/Week 8.
    Description Assessing the change from baseline to Month 1/Week 4 and Month 2/Week 8, of the urinary growth factor (GF) to creatinine ratio in men, which may be potential biomarker for overactive bladder, based on published articles. Measuring the ratio at baseline compared to Month 1 and Month 2 may provide insight into how lower urinary tract symptoms in men progresses.
    Time Frame change from baseline score to Mo.1/Wk4 and Mo.2/Wk8 scores
