A Trial of Transcranial Magnetic Stimulation in the Treatment of Functional Dyspepsia

NCT ID: NCT06559748

Last Updated: 2024-08-19

Basic Information

• Recruitment Status: TEMPORARILY_NOT_AVAILABLE
• Study Classification: EXPANDED_ACCESS

Brief Summary

The goal of this clinical trial is to learn if theta burst stimulation (TBS), a form of Transcranial Magnetic Stimulation (TMS), can treat functional dyspepsia (FD) and compare its effectiveness against conventional drug treatments in patients diagnosed with FD. The main questions it aims to answer are:

Does TBS improve FD-related symptoms and associated mental health conditions such as anxiety and depression? How does the effectiveness of TBS compare to conventional drug treatments for FD?

Researchers will compare TBS treatment, sham TBS treatment, and conventional drug treatment to see if TBS is effective in treating FD. Participants will:

Undergo TBS or sham TBS treatment, or take conventional medications as prescribed.

Have their FD symptoms, anxiety, and depression levels assessed before and after the treatment.

Be evaluated at various intervals (Day 3, Month 1, Month 3, Month 6) for symptom improvement and side effects.

Participants are adults aged 18-70, diagnosed with FD, and willing to participate in this study. They will be randomly assigned to one of the three groups: TBS, sham TBS, or conventional drug treatment, with an equal number of participants in each group.

The study will be conducted over two years, from November 1, 2023, to October 31, 2025, at the Second Affiliated Hospital of Zhejiang University School of Medicine.

Detailed Description

Background:

Functional dyspepsia (FD) is a prevalent gastrointestinal disorder characterized by upper abdominal discomfort, including symptoms such as pain, bloating, early satiety, belching, and nausea. The etiology of FD is multifactorial, with psychosocial factors playing a significant role in its development. Recent advances in understanding the brain-gut axis have highlighted the potential of non-invasive neuromodulation techniques, such as Transcranial Magnetic Stimulation (TMS), to modulate brain activity and alleviate FD symptoms.

TMS, particularly theta burst stimulation (TBS), has shown promise in treating various neurological and psychiatric disorders. This study aims to explore the efficacy of TBS in improving both gastrointestinal symptoms and associated psychological symptoms in patients with FD, providing a novel therapeutic option for this challenging condition.

Objective:

The primary objective of this study is to compare the efficacy of TBS, sham TBS, and conventional pharmacological treatments in alleviating the symptoms of functional dyspepsia. The study seeks to determine whether TBS can offer superior symptom relief compared to standard treatment methods.

Study Design:

This is a single-center, randomized controlled clinical trial with 2 parallel arms: TBS treatment, and conventional drug therapy. Participants will be randomly assigned to one of the 2 groups in a 1:1 ratio. The study will be conducted over two years, from November 1, 2023, to October 31, 2025.

Intervention:

• TBS Group: Participants will receive iTBS stimulation of the right medial frontal cortex (RMFC) at 80-100% of their resting motor threshold (RMT), with 10 sessions per course, administered twice daily for five days.
• Conventional Drug Group:Participants will receive pantoprazole (40 mg orally once daily) and itopride (50 mg orally three times daily) for four weeks.

Participants:

The study will enroll 150 adult outpatients (aged 18-70 years) diagnosed with functional dyspepsia according to the Rome IV criteria. Participants will be screened based on specific inclusion and exclusion criteria and will provide informed consent before enrollment.

Data Management and Statistical Analysis:

All data will be collected and analyzed using SPSS 19.0 software. The analysis will include t-tests for normally distributed data and non-parametric tests for non-normally distributed data. The study will also employ multifactor ANOVA to assess the impact of various factors on treatment outcomes.

Ethical Considerations:

The study will be conducted in accordance with ethical standards, ensuring participant confidentiality and safety. Adverse events will be closely monitored and reported to relevant regulatory bodies.

This study aims to provide evidence for the clinical efficacy of TBS in treating FD, potentially offering a new therapeutic approach for managing brain-gut axis-related disorders.
