Aquarius Pilot of the New Axonics External System for Bladder and Bowel Control

Official title: Prospective, Multicenter, Single Arm Feasibility and Safety Study of the Axonics External Trial System (ETS-02)

Run by Axonics, Inc. · NCT07335484 · Data updated 2026-11-12

This pilot will try the Axonics External Trial System in adults with overactive bladder or fecal incontinence to see if they respond to sacral neuromodulation before getting a permanent implant.

Is this trial a fit for you?

Likely a good fit

Adults 18 or older with OAB (urinary urgency incontinence or frequency) or chronic fecal incontinence who are considered candidates for a percutaneous nerve evaluation and can complete symptom diaries and follow study visits.

Probably not a fit

Patients with current urinary tract obstruction or symptomatic UTI, those planning medication changes that affect bladder or bowel function, or anyone unable to complete baseline diaries or comply with study visits may not receive benefit from this external trial.

What this trial studies

The Aquarius Pilot tests the Axonics External Trial System (ETS-02) in adults with overactive bladder (OAB) or chronic fecal incontinence (FI) to evaluate feasibility and safety. Participants undergo a temporary external sacral neuromodulation trial using the ETS-02 to determine symptomatic response prior to consideration of the approved Axonics implantable neurostimulator. The study collects bladder or bowel diaries, tracks symptom changes, and records device-related adverse events with scheduled follow-up visits. Results will inform whether the ETS-02 can reliably identify candidates for permanent sacral neuromodulation.

Why it matters

Potential benefit: If successful, the ETS-02 could help identify which patients will benefit from a permanent Axonics implant while avoiding unnecessary surgery for non-responders.

How similar studies have gone: Sacral neuromodulation with Axonics implants is approved and effective for OAB and FI and external temporary trials are commonly used to identify responders, but the ETS-02 device itself is being piloted for feasibility and safety.
