The purpose of this study is to assess the effects of AV608, a neurokinin 1 (NK-1) antagonist, in subjects with Idiopathic Detrusor Overactivity.

Condition Intervention Phase
Overactive Bladder Syndrome Drug: AV608 Phase 2

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double
Primary Purpose: Treatment
Official Title: A Phase 2, Randomized, Double-Blind, Placebo-Controlled Trial to Investigate the Safety and Efficacy of AV608 in Subjects With Idiopathic Detrusor Overactivity

Further study details as provided by Avera Pharmaceuticals:

Primary Outcome Measures:
  • Comparison between treatment groups of the change from baseline in maximum cystometric bladder capacity

Secondary Outcome Measures:
  • Delay of the first involuntary detrusor contraction associated with symptomatic urgency
  • Urgency, frequency and urge incontinence events as recorded in the Subject Micturition Diary
  • Urgency Perception Scale

Estimated Enrollment: 62
Study Start Date: June 2006
Study Completion Date: September 2007
Primary Completion Date: June 2007 (Final data collection date for primary outcome measure)
Detailed Description:

This is a Phase 2, randomized, double-blind, placebo-controlled trial to evaluate the safety and efficacy of AV608 in subjects with idiopathic detrusor overactivity. Female subjects between 18 and 65 years of age with a diagnosis of Overactive Bladder Syndrome and urodynamic observation of involuntary detrusor contractions during the filling phase will be eligible for the trial.

Eligible subjects will complete a baseline urodynamic assessment. All subjects who participate in the study will receive 3 weeks of treatment with AV608 or placebo. At the end of the treatment period, subjects will complete a second urodynamic assessment.

  • Written informed consent form
  • Willingness to avoid pregnancy and practice adequate birth control
  • Negative serum pregnancy test
  • Agrees to refrain from blood donation during the course of the study

Exclusion Criteria:

  • Subjects who are pregnant or lactating

  • Anatomic or structural abnormalities possibly causing urinary incontinence or urgency, including but not limited to urogenital prolapse stage 2 or more according to the Pelvic Organ Prolapse Quantification (POP-Q) system
  • Urological or gynecological surgery within 3 months of the baseline urodynamic assessment
  • Current UTI or frequent UTIs (i.e., greater than or equal to 4 UTIs per year), interstitial cystitis, hematuria of unknown cause, or use of indwelling catheter
  • Electro-stimulation therapy, bladder training, or physiotherapy for bladder control within 2 weeks of Visit 1
  • History (within 1 year of Screening) of alcohol or substance dependence (except nicotine dependence) according to DSM‑IV‑TR criteria
  • History of any kind of cancer within the last 2 years
  • Existing non-malignant tumors that could compromise the function and/or anatomy of the lower urinary tract
