Summary

This trial is testing a new treatment called Translumbosacral Neuromodulation Therapy (TNT) for people with fecal incontinence (FI), especially women and elderly individuals. TNT uses magnetic pulses to stimulate nerves in the lower back, helping to improve control over bowel movements. The goal is to provide a more effective, non-invasive treatment option for those who struggle with FI.

Who is the study for?
This trial is for adults who've had bowel incontinence for at least 6 months, with weekly episodes. They must not have mucosal diseases, be on opioids, or have a range of other conditions like Crohn's disease, severe heart issues, metal implants near the treatment area, pacemakers, or certain past surgeries.
What is being tested?
The study tests Translumbosacral Neuromodulation Therapy (TNT) against a sham (fake) therapy to see if TNT can improve bowel control by stimulating nerves with magnetic fields. It aims to find the best dose and understand how it works over short and long terms.
What are the potential side effects?
While specific side effects are not listed here, non-invasive magnetic stimulation therapies like TNT may cause discomfort at the site of application or mild headaches. Serious side effects are rare but could include seizures in susceptible individuals.

Study Objectives

Study objectives can provide a clearer picture of what you can expect from a treatment.
Primary study objectives
AIM 1 measure is the proportion of patients achieving >50% of reduction in fecal incontinence episodes/weeks at the end of 6 weeks compared to baseline.
AIM 2: Latencies for lumbo-anal Magnetic Evoked Potentials (MEP) responses compared to baseline
AIM 2: Latencies for sacro-anal MEP responses compared to baseline
+5 more
Secondary study objectives
Amplitudes (Milivolts of the nerve) for lumbo-rectal MEP compared to baseline
Amplitudes (Milivolts of the nerve) for recto-cortical CEP responses
Amplitudes (Milivolts of the nerve) for sacro-rectal MEP
+24 more

Trial Design

3Treatment groups
Active Control
Placebo Group
Group I: 1 Hz 2400 TNT TreatmentActive Control1 Intervention
Intervention: TNT treatment intervention with 2400 total stimulations with the magnetic coil..
Group II: 1 Hz 3600 TNT TreatmentActive Control1 Intervention
Intervention: TNT treatment intervention with 3600 total stimulations with the magnetic coil.
Group III: Sham TNT TreatmentPlacebo Group1 Intervention
This arm will have the sham treatment session. First we will assess the motor threshold intensity described above. Next, a sham coil is placed on each of 4 regions (2 lumbar \& 2 sacral), and 600 stimulations will be given at each site in 2 trains, with a 5 minutes rest period between each site and 3 minutes between trains.

Mechanism Of Action
Side Effect Profile
Prior Approvals
Other Research
The most common treatments for Bowel Incontinence, such as Translumbosacral Neuromodulation Therapy (TNT), work by enhancing neural excitability and inducing neuroplasticity. These mechanisms improve sensory and motor control by modulating neuronal perturbations, which in turn enhance bidirectional gut-brain signaling, anal sphincter strength, and rectal sensation. This is important for Bowel Incontinence patients as it offers a durable, non-invasive, and low-risk treatment option that addresses the underlying neurobiologic dysfunctions contributing to their condition.
