VESIcare For Improving OAB Symptoms in Patients Undergoing IGRT of the Prostate

Overview

The purpose of this study is to determine if Vesicare (Solifenacin succinate) is effective in treating over-active bladder symptoms during radiation therapy of the prostate.

Full Title of Study: “A Pilot Study to Assess the Safety and Efficacy of Solifenacin (VESIcare) for Improving Urinary and Bladder Functions in Patients Undergoing Radiation Therapy of the Prostate”

Study Type

  • Study Type: Interventional
  • Study Design
    • Allocation: Randomized
    • Intervention Model: Parallel Assignment
    • Primary Purpose: Treatment
    • Masking: Triple (Participant, Care Provider, Investigator)
  • Study Primary Completion Date: January 2014

Detailed Description

This is a randomized double blind placebo controlled flexible dose 12 week study. Following screening, subjects will receive their first dose of study medication following completion of AUASS questionnaire on the first day of radiation treatment (baseline) and will continue for twelve weeks. Subjects will be started on 5 mg of study medication. The AUASS will be completed at baseline, weeks 4, 8 and 12. A 16 week visit conducted over a phone interview.

Interventions

  • Drug: Solifenacin succinate
    • IGRT with VESIcare
  • Drug: Placebo
    • IGRT with placebo

Arms, Groups and Cohorts

  • Active Comparator: solifenacin succinate
    • Solifenacin succinate, 5mg or 10 mg once daily
  • Placebo Comparator: Placebo
    • Drug: Placebo oral

Clinical Trial Outcome Measures

Primary Measures

  • Change From Baseline to End of Study Measured by the American Urology Association Symptom Score Questionnaire (AUASS).
    • Time Frame: baseline and 16 weeks
    • The AUASS score range is 1-7 (mild), 8-19 (moderate) and 20-35 (severe). The AUASS asks 7 questions scored 0-5, the scores are summed for the total score.
