Condition(s) targeted: Overactive Bladder

Intervention: Fesoterodine fumarate (Drug); Placebo (Drug); Percutaneous Tibial Nerve Stimulation (PTNS) (Procedure)

Phase: Phase 4

Status: Terminated

Sponsored by: Mayo Clinic

Official(s) and/or principal investigator(s):
Jeffrey Cornella, MD, Principal Investigator, Affiliation: Mayo Clinic

Summary

The investigators are studying two FDA-approved modalities used to treat overactive bladder to determine if they improve overactive bladder with or without urge incontinence when used together rather than separately, percutaneous tibial nerve stimulation (PTNS) versus PTNS and fesoterodine fumarate.

Clinical Details

Official title: Prospective Randomized Trial of Percutaneous Tibial Nerve Stimulation (PTNS) Versus PTNS and Fesoterodine Fumarate

Study design: Allocation: Randomized, Endpoint Classification: Efficacy Study, Intervention Model: Crossover Assignment, Masking: Double Blind (Subject, Investigator), Primary Purpose: Treatment

Primary outcome: Number of Urinary Voids Per 24 Hours After 12 Weeks of Therapy

Secondary outcome:

Mean Change in Urinary Urge Incontinence Episodes in 24 Hours

Number of Voids Causing Waking

Volume Voided Per Day

Number of Urgency Episodes Scored by the Indevus Urgency Severity Scale (IUSS)

Change in Score on Overactive Bladder Questionnaire (QAB-q)

Detailed description: Overactive bladder (OAB) is described as urinary urgency with or without urge incontinence, usually associated with urinary frequency and nocturia. The primary complaint is a strong desire to void without the ability to postpone micturition. Two treatments used in the treatment of OAB are pharmacotherapy and percutaneous tibial nerve stimulation (PTNS). Pharmacotherapy for OAB is based on medications that block the muscarinic receptors of the detrusor muscle. These particular receptors are not unique to the bladder, however, and patients complain of bothersome side effects that are a result of systemic muscarinic receptor blockade. Medications are successful for many patients but compliance is poor and many patients discontinue the medications as a result of side effects, cost, and insufficient symptom improvement. Percutaneous tibial nerve stimulation (PTNS) is a newer treatment modality that provides neuromodulation to the pelvic floor by stimulating the posterior tibial nerve. This nerve is accessed with a fine needle electrode that is inserted in the medial portion of the ankle. This area has long been recognized as having nerve projections to the sacral nerve plexus and can modulate bladder activity. Several studies have clearly demonstrated the effectiveness of neuromodulation to treat urge incontinence. There have been studies comparing the efficacy of pharmacotherapy versus PTNS. In one study, 49% of subjects taking fesoterodine fumarate for urge incontinence reported an improvement in symptoms of overactive bladder. In other studies, 79. 5% of patients undergoing PTNS reported improvement or cure. Although studies report similar improvement or cure between the two treatment modalities, there is no evidence of the efficacy of using both PTNS and pharmacotherapy concurrently. This study is aimed at proving synergy between the two treatment modalities when used together in an effort to administer smaller doses of anticholinergic agents, while obtaining comparable or improved urge incontinence.
