PRospective Study to Evaluate EffectivenesS With the NURO™ PErcutaneous Tibial Neuromodulation System in Patients With OAB

The purpose of this prospective, multicenter, single arm study is to evaluate the NURO system
for the treatment of OAB in drug naïve patients. The study will assess change from baseline
through 12 PTNM therapy sessions in UUI (urge urinary incontinence) episodes, voiding
episodes, and patient reported outcomes. The study is expected to last approximately 14 weeks
per subject following the enrollment visit. Subjects will be exited from the study after the
final study visit is complete.

Inclusion Criteria:

1. 18 years of age or older

2. Diagnosis of OAB and associated symptoms of UUI and qualify with at least 3 episodes
of mild, moderate, or severe urgency demonstrated on a 3-day urinary voiding diary

3. Experiencing UUI symptoms for at least 3 months

4. No prior treatment with anticholinergics/antimuscarinics or beta 3-agonists
medications to treat OAB

5. Willing and able to accurately complete voiding diaries and questionnaires, attend
visits, and comply with the study protocol

6. Willing and able to provide signed and dated informed consent

Exclusion Criteria:

1. Have received anticholinergics/antimuscarinics or beta 3-agonists medications to treat
OAB or advanced therapy treatment options for OAB (botulinum toxin injections, sacral
neuromodulation, or percutaneous tibial nerve stimulation/neuromodulation)

2. Primary stress incontinence or mixed incontinence where the stress component overrides
the urge component

3. Have implantable pacemakers or implantable defibrillators

4. Use of transcutaneous electrical nerve stimulation (TENS) in pelvic region, back or
legs

5. Women who are pregnant or planning to become pregnant during the course of the study

6. Characteristics indicating a poor understanding of the study or characteristics that
indicate the subject may have poor compliance with the study protocol

7. Nerve damage that could impact either tibial nerve or pelvic floor function.

8. Subjects prone to excessive bleeding

9. Inadequate skin integrity in the area of PTNM needle placement

10. History of diabetes unless the diabetes is well-controlled through diet and/or
medications

11. Have symptomatic urinary tract infection (UTI)

12. Participation in any research study involving or impacting gynecologic, urinary or
renal function within the 4-week period prior to or plans to participate during study
enrollment
