APPROVE Trial: Evaluating a Prescription Digital Therapeutic for Treatment of OAB in Women

In this trial, we will employ a randomized controlled trial design to determine if women with overactive bladder (OAB) treated with the RiSolve prescription digital therapeutic (PDTx) demonstrate greater improvement in OAB-related health as compared to standard behavioral education with informational handouts. RiSolve is a digital therapeutic device intended to provide behavioral therapy and cognitive behavioral therapy (CBT) for adult women who have been diagnosed with OAB, which includes urinary urgency with or without urge urinary incontinence (UUI), urinary frequency, nocturia, and mixed incontinence with predominant OAB symptoms. RiSolve is indicated as an 8-week treatment to reduce the symptoms of OAB.

For the purposes of this trial, the primary outcome to determine improvement in OAB-related health will be defined as achieving the MID (defined as an improvement of 10 points or more) on the OAB-q SF Symptom Severity subscale after 8 weeks of treatment. Secondary outcomes will include achieving the MID on the OAB-q SF Health-Related Quality of Life subscale, meeting the patient's acceptable symptoms state (PASS) on the Patient Global Impression of Severity (PGI-S) and Patient Global Impression of Improvement (PGI-I), and improvements in frequency, nocturia and urge urinary incontinence (UUI) on a 3-day bladder diary and on the ICIQ-FLUTS. Participants will be randomized to either PDTx therapy (active) or standard treatment of behavioral education (control). Participants randomized to control will have the option to crossover to PDTx after the initial 8 weeks of the trial if desired. Participants will continue to be followed and asked about their symptoms at 6 and 12 months.

The impact of this trial has enormous potential to improve treatment of OAB. The ability to offer behavioral therapy via PDTx will reduce patient burden while simultaneously increasing quality of life for women suffering from OAB and decreasing provider burden. The high-quality data from this study will be used to support a marketing application with the FDA through the De Novo pathway for an accessible, low-burden, efficient intervention to help millions of women currently suffering from this burdensome condition.
