Overactive Bladder Trial Phases
34 research organizations are sponsoring overactive bladder trials.
About Overactive Bladder
Overactive bladder (OAB) is a condition causing a sudden, frequent urge to urinate that may be difficult to control. It affects millions of adults and can significantly impact quality of life. Treatment includes behavioral therapy, medications (anticholinergics), and nerve stimulation.
Clinical trials are advancing new treatments for overactive bladder. Currently, 38 studies are recruiting a combined 6,718 participants across the United States. Research is being conducted by 34 organizations including Mayo Clinic, Medstar Health Research Institute, Darren Schneider, M.D. and 31 others.
2026 Overactive Bladder Research Landscape
As of July 2026, the overactive bladder clinical trial landscape includes 38 actively recruiting studies across 76 cities in the United States. These studies are collectively seeking 6,718 participants, with an average enrollment target of 177 per study.
The research spans multiple phases of development: 25 studies are in NA, 4 studies are in PHASE4, 4 studies are in PHASE2, 3 studies are in PHASE3, 1 study is in PHASE1. The presence of Phase 3 trials indicates that some overactive bladder treatments are in late-stage testing and may be approaching regulatory review.
Research is being led by 34 different organizations, including Mayo Clinic, Medstar Health Research Institute, Darren Schneider, M.D., MedtronicNeuro, University of Washington, and 29 others. The large number of sponsors reflects significant research interest and investment in overactive bladder treatment advancement.
Geographically, overactive bladder trials are most concentrated in Chicago, Illinois (7 trials); Washington D.C., District of Columbia (4 trials); Bethesda, Maryland (4 trials); Palo Alto, California (3 trials); New Orleans, Louisiana (3 trials) and 7 other cities.

The purpose of this study is to test a new ultrasound method called Quantitative Ultrasound Bladder Vibrometry to detect abnormal bladder function.
APPROVE Trial: Evaluating a Prescription Digital Therapeutic for Treatment of OAB in Women
The APPROVE trial is a multi-centered, randomized controlled trial designed to assess differences in symptom improvement, quality of life, bladder symptoms, satisfaction with treatment and continued treatment efficacy in women with overactive bladder (OAB) randomized to a prescription digital therapeutic (PDTx) app called RiSolve compared to standard behavioral education (handouts).
Endovascular Treatment of TAAA and Aortic Arch Aneurysms Using Fenestrated and Branched Stent Grafts
Prospective, nonrandomized, single-center, two-arm study to assess the feasibility and safety and to evaluate clinical outcomes of endovascular repair of complex aortic aneurysms (thoracoabdominal aortic aneurysms and aortic arch aneurysms) in patients at high risk for open surgery.
