Study Details

Study Description

Brief Summary

This trial is a prospective, multicenter, single-arm study of the safety and effectiveness of eCoinTM tibial nerve stimulation in subjects having overactive bladder (OAB) with urgency urinary incontinence (UUI). The study will evaluate changes from baseline in OAB symptoms as measured by voiding diaries and patient reported-outcomes through 48 weeks of eCoinTM therapy or 52 weeks of implantation.

Adverse Events

Time Frame 52 weeks post-implantation
Adverse Event Reporting Description The analysis set is comprised of "treatment emergent" adverse events, defined as adverse events occurring on or after implantation or attempted implantation of eCoin. Importantly, all attempted implantations were successful; thus, the safety results are summarized for all implanted patients. At each follow-up visit, patients were asked to report any adverse events and it was recorded on the CRF.

Limitations/Caveats

A limitation of the study was the lack of blinding and comparison. Considering that neuromodulation studies are generally not blinded since the therapy itself is sensed, a control group with a similar safety profile to eCoin could not be achieved. We also acknowledge that a 12-month endpoint provides only medium-term data on the durability of response and future longer follow up data will be needed.
