Trial Summary

What is the purpose of this trial?

The Revi System is indicated for the treatment of patients with symptoms of urgency incontinence alone or in combination with urinary urgency.

Will I have to stop taking my current medications?

The trial requires that if you are taking antimuscarinics, beta-3 adrenergic agonists, tricyclic antidepressants, SSRIs, or SNRIs, you must be on a stable dose for a certain period before starting and remain on it throughout the trial. The protocol does not specify about other medications, so it's best to discuss with the trial team.

What data supports the effectiveness of the Revi System treatment for urge incontinence?

Research shows that similar treatments using electrical stimulation of the tibial nerve, like the eCoin® and Urgent-SQ™, have been effective in treating urgency urinary incontinence and overactive bladder syndrome, suggesting potential benefits for the Revi System as well. ^{1 2 3 4 5}

How is the Revi System treatment different from other treatments for urge incontinence?

The Revi System treatment is unique because it involves a fully implanted device that provides electrical stimulation to the tibial nerve, which is different from traditional medications or external therapies. This approach is similar to other neuromodulation devices like the eCoin® and Axonics® systems, but it specifically targets the tibial nerve, potentially offering a novel method for managing urge incontinence. ^{1 3 6 7 8}

Treatment Details

Interventions

• Revi System - Delayed Activation
• Revi System Treatment

Trial Overview The RESTORE trial is testing the Revi System's effectiveness for treating symptoms of urgency incontinence. Participants will receive either immediate or delayed treatment with the Revi System to compare outcomes.

Participant Groups

Group I: Device: Revi System Treatment Arm Experimental Treatment 1 Intervention

Subjects will be implanted with a Revi System and activation of therapy will occur \~4 weeks post implantation and continue for the duration of the study.

Group II: Device: Revi System - Delayed Activation Control Arm Experimental Treatment 1 Intervention

Subjects will be implanted with a Revi System and activation of therapy will be delayed until 4 months post implantation. At this time the Revi System will be activated to begin therapy and will continue for the duration of the study.

Revi System - Delayed Activation is already approved in United States for the following indications:

Approved in United States as Revi System for:

• Urgency incontinence alone or in combination with urinary urgency

Findings from Research

The eCoin® neuromodulation device, implanted in 46 participants with refractory urgency urinary incontinence, demonstrated a significant 71% reduction in daily episodes of incontinence after 3 months, indicating its efficacy in treating this condition.

The device was found to be safe, with only one serious adverse event related to wound care, which was resolved with treatment, suggesting minimal safety concerns associated with its use.

The Urgent-SQ™ implant for posterior tibial nerve stimulation has been shown to be a safe and effective long-term treatment for refractory overactive bladder syndrome, with positive results observed in a 9-year follow-up of seven patients.

Most patients reported continued efficacy and ease of use of the device, with no significant complications such as migration or displacement of the implant, indicating its durability and patient tolerance.

Functional electrical stimulation (FES) can effectively enhance bladder voiding in patients with incontinence, particularly through the use of the Finetech-Brindley bladder system that stimulates sacral roots.

A new approach is being developed to use FES for incontinence in spinal cord injury patients without the need for dorsal rhizotomy, which traditionally eliminates important reflexes like defecation and erection.

In a study of 112 women with mixed urinary incontinence, the combination of transobturator tape (TOT) and posterior tibial nerve stimulation (PTNS) significantly improved urinary function and quality of life compared to TOT alone.

The combined treatment resulted in better outcomes in peak flow rates, first voiding desire, and maximum cystometric capacity, indicating that sequential therapy is more effective for managing urinary incontinence symptoms.

In a study of 46 patients with stress urinary incontinence, biofeedback and pelvic electric stimulation treatments resulted in a 93% improvement rate, demonstrating high efficacy for this intervention.

The treatment was effective regardless of menopause status, body mass index (BMI), or severity of incontinence, indicating that these factors do not significantly impact the success of the therapy.

In a study involving six paraplegic patients with urinary incontinence due to an overactive bladder, pelvic floor stimulation using implanted electrodes led to significant improvements, with four patients experiencing reduced incontinence and two achieving complete resolution.

Urodynamic tests showed that the procedure effectively increased bladder capacity and inhibited detrusor overactivity, suggesting that this method could be a reliable long-term treatment option for urinary incontinence in spinal cord injury patients.

The Axonics® System is an FDA-approved continuous sacral neuromodulation therapy that has been shown to be a safe and effective treatment for overactive bladder and urge urinary incontinence, providing significant patient satisfaction.

This device features a rechargeable, compact design that is MRI safe and offers a long battery life of approximately 15 years, although patients may face challenges related to the need for regular recharging.

The sacral anterior root stimulator, combined with sacral posterior rhizotomy, has proven effective for treating urinary incontinence in patients with spinal cord injuries and is expected to have broader applications.

The conditional pudendal nerve stimulator and conditional gracilis nerve stimulator are emerging treatments that show potential for helping many patients, although they have not yet been widely tested.
