Active clinical trials for "Urinary Bladder, Overactive"

Sacral nerve stimulation (SNS) implantation is a minimally invasive procedure which has current FDA approval for urinary urge incontinence, urgency-frequency syndrome and non-obstructive urinary retention, and has been available in the United States since 1997. The SNS delivers non-painful, mild electrical pulses to the sacral nerves to modulate the reflexes that influence the bladder, sphincter, and pelvic floor to improve or restore normal voiding function. While SNS has been shown to have efficacy for the aforementioned conditions, the exact mechanism of action is unknown, but it is believed to work primarily through the somatic afferent system in promoting inhibitory reflex pathways to facilitate urine storage. The degree of stimulation is thought to be at a level that only evokes a sensory and not a motor response; however this has not been tested.

This bioequivalence (BE) study is to satisfy FDA regulatory requirements for extended releases drug product transfer from Zwickau, Germany to Vega Baja, Puerto-Rico.

This is an open-label (both the physician and healthy volunteer know which medication will be administered), single-dose, 2-cohort, 3-period study to characterize the pharmacokinetics (process by which drug fesoterodine is absorbed, distributed, metabolized, and eliminated by the body) and the effects of food on the pharmacokinetics of the drug. This study will take place over approximately 8 weeks and will consist of a screening visit to determine eligibility for the study, and 2- or 3-period treatment phase for each cohort.

Nerve growth factor (NGF), prostaglandin E2 (PGE2)and adenosine triphosphate (ATP) levels in urine were reported to increase in patients with overactive bladder (OAB). Also, administration of the anti-muscarinic agent was reported to decrease urinary NGF and ATP. The investigators aimed to explore the value of the urinary NGF, PGE2 and ATP as biomarker for predicting the treatment responsiveness and symptom relapse in OAB patients. So, the patients can be categorized into responder or non- responder and relapse or non-relapse groups. Ultimately, they can receive individualized treatments.

The trial consisted of a 2 week Run-In period, 12 week double-blind Treatment period and 2 week Safety Follow-Up period. Subjects were randomized to one of 4 treatment arms receiving either fesoterodine (SPM 907) 4mg, fesoterodine 8mg, active control (tolterodine SR 4mg) or placebo during the Double-Blind Treatment Period. Two primary efficacy variables will be assessed for submission in the United States: change in the average number of micturitions (frequency) per 24 hours and the change in the average number of urge incontinence episodes per 24 hours. For the submissions in the European Union, the first primary variable will be the change in the average number of micturitions (frequency) per 24 hours and the co-primary variable is the treatment response, based on a treatment benefit scale. All continuous variables will be measured as changes from baseline to value after 12 weeks of treatment. The most important safety variables included the assessment of adverse events, laboratory parameters, changes in ECG, physical exams and measurement of residual urine.

This Phase 3 trial will investigate the efficacy, tolerability and safety of fesoterodine fumarate (SR) (fesoterodine; SPM 907) in adult male and female subjects with overactive bladder syndrome. The trial is a randomized, double-blind placebo controlled multicenter trial. The trial consisted of a 2 week Run-In period, 12 week double-blind Treatment period and 2 week Safety Follow-Up period. Subjects were randomized to one of 3 treatment arms receiving either fesoterodine fumarate 4mg, fesoterodine fumarate 8mg, or placebo during the double-blind Treatment period. Two primary efficacy variables will be assessed for submission in the United States: change in the average number of micturitions (frequency) per 24 hours and the change in the average number of urge incontinence episodes per 24 hours. For the submissions in the European Union, the first primary variable will be the change in the average number of micturitions (frequency) per 24 hours and the co-primary variable is the treatment response, based on a treatment benefit scale. All continuous variables will be measured as changes from baseline to value after 12 weeks of treatment. The following safety variables were observed and assessed: adverse events, change in residual urinary volume (mL), change in laboratory parameters, change in vital signs, change in electrocardiogram (ECG), change in physical examination and change in urological/urogynecological examination.

Overactive bladder(OAB,Urgency) was determined by International Continence Society as Urinary urgency, usually accompanied by frequency and nocturia, with or without urgency urinary incontinence, in the absence of urinary tract infection (UTI) or other obvious pathology.The SNM treatment involves a two-stage surgical procedure performed under local anesthesia. The device include IPG (implantable programme generator) and lead. In the initial test phase, 1st stage, electrode is placed near the sacral nerve and requires a 2 weeks assessment. This allows your doctors and you to assess your initial response according to your voiding dairy and satisfaction. In 2nd stage, SNM procedure is implantation of the IPG. X ray guidance is harmful to both patients and doctors, while ultrasound guidance is real time visual guidance ,easy to operate by doctors and a radiation free option to challenge anatomy. Urologists are skilled in both ultrasound operations and anatomy basics and dedicating to developing better guidance technique in surgery. The study here compare the efficacy and safety of ultrasound versus X ray guidance technique in SNM.

The overall objective of this study is to compare the efficacy of the standard monthly maintenance therapy for percutaneous tibial nerve stimulation (PTNS), to sessions as the patient needs (prn) between 2 weeks and 12 weeks, based on overactive bladder symptoms. This is study is to help determine feasibility for conducting a larger trial that is appropriately powered to provide meaningful data.

The purpose of this study is to investigate the safety and efficacy of combination therapy involving β3-adrenoceptor agonist, mirabegron, and α-blockers for the treatment of OAB symptoms in male patients with BPH.

We hypothesize that LESWs might temporarily increase urothelial permeability and facilitate delivery of intravesical botulinum toxin without the need for injection.
