What is the purpose of this trial?

Neurogenic overactive bladder (NOAB), characterized by urinary frequency, urgency or urgency incontinence symptoms occurring during the storage phase of the bladder, is the most common urinary complaint in multiple sclerosis (MS). Current management options for NOAB in MS have limited efficacy and considerable adverse effects, which underscores the significance of this study and highlights the need for better, less invasive therapies. This novel study investigates brain therapeutic targets that could shift the focus of NOAB management in MS from a bladder-centric focus to brain restoration; specifically modulating the brain regions identified in the prior functional magnetic resonance imagining studies. Repetitive transcranial magnetic stimulation (rTMS) is a noninvasive brain stimulation that can modulate neurons (excite or inhibit) to improve the connectivity of the regions of interest (ROI). The preliminary data demonstrate, for the first time, significant improvement in bladder symptoms in ten women with MS who have voiding dysfunction following multifocal transcranial magnetic stimulation without any treatment-related adverse effects.This randomized double-blind, sham-controlled single center clinical trial with an optional open-label extension (OLE) phase is designed to evaluate the effects of targeted rTMS in women with MS and NOAB by investigating restorative reorganization of brain function The main purpose of this study is to determine the effects of individualized repetitive Transcranial Magnetic Stimulation (rTMS) for improving overactive bladder symptoms such as urinary frequency and urgency with or without incontinence in individuals with multiple sclerosis (MS). Patients will undergo initial screening that includes a demographics information, physical exam, past medical and surgical history, medication list, urine pregnancy test (female subjects with childbearing potential), and completion of questionnaires to confirm the eligibility of patients. All eligible patients will be required to complete a functional MRI scan followed by locating the regions of interest through neural navigation system and finally receiving 10 treatment sessions.Since this is a randomized trial, some patients will receive active treatment/ therapy sessions while others will only receive sham or placebo treatments. The total duration to complete all treatment sessions and follow up visits is approximately 4-5 months.

Will I have to stop taking my current medications?

The trial does not specify if you need to stop taking your current medications. However, if you are taking medications that lower the seizure threshold or exacerbate bipolar disorder, you may be excluded from participating.

Is non-invasive brain stimulation safe for humans?

Non-invasive brain stimulation, like repetitive Transcranial Magnetic Stimulation (rTMS), has been studied for various conditions and is generally considered safe in humans. Studies have shown it can be used without serious side effects for conditions like neuropathic pain, voiding dysfunction in multiple sclerosis, and urinary disturbances in Parkinson's disease.12345

How is the Magstim Rapid2 System treatment different from other treatments for neurogenic bladder in MS?

The Magstim Rapid2 System, using repetitive Transcranial Magnetic Stimulation (rTMS), is unique because it is a non-invasive treatment that targets the brain to improve bladder function, unlike traditional methods like catheterization which directly manage the bladder. This approach aims to enhance brain and spinal cord communication to improve bladder control in MS patients.13456

What data supports the effectiveness of the treatment Magstim Rapid2 System, Repetitive Transcranial Magnetic Stimulation (rTMS) for neurogenic bladder in MS?

Research shows that repetitive transcranial magnetic stimulation (rTMS) over the motor cortex can improve bladder function in multiple sclerosis (MS) patients by enhancing the ability to urinate. This suggests that rTMS might help with bladder issues in MS by improving muscle control involved in urination.13456

Published Research Related to This Trial

Transcutaneous magnetic spinal cord stimulation (TMSCS) significantly improved bladder function in five individuals with chronic spinal cord injury, enabling all subjects to achieve voluntary urination after treatment.
After 16 weeks of TMSCS, participants experienced a notable increase in urine volume produced voluntarily (from 0 cc/day to 1120 cc/day) and a decrease in self-catheterization frequency, indicating enhanced bladder capacity and improved quality of life.
A Proof-of-Concept Study of Transcutaneous Magnetic Spinal Cord Stimulation for Neurogenic Bladder.Niu, T., Bennett, CJ., Keller, TL., et al.[2022]
In a study involving multiple sclerosis (MS) patients with lower urinary tract symptoms, 5-Hz repetitive transcranial magnetic stimulation (rTMS) applied over the motor cortex for five consecutive days improved the voiding phase of urination.
The results suggest that increasing excitability in the corticospinal tract may help improve bladder function by enhancing detrusor contraction and urethral sphincter relaxation in these patients.
Effects of motor cortex rTMS on lower urinary tract dysfunction in multiple sclerosis.Centonze, D., Petta, F., Versace, V., et al.[2022]
In a pilot trial involving 10 women with multiple sclerosis and voiding dysfunction, the Transcranial Rotating Permanent Magnet Stimulator (TRPMS) was found to be safe, with no reported adverse effects during treatment.
Post-treatment results showed significant improvements in brain activation related to voiding initiation and a decrease in post-void residual bladder capacity, indicating that TRPMS can effectively enhance bladder emptying in these patients.
