Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study is a multi-center prospective cohort study, which plans to include 300 patients with chronic functional constipation to treat with Vibrabot capsules, and at the same time, include ≥300 patients receiving constipation treatment during the same period.

During the study, it is necessary to collect the patients' basic information, baseline constipation status and treatment information, capsule intake during treatment, and concomitant medication. During the treatment phase, patients follow the doctor's advice to receive Vibrabot capsule treatment and maintain stable dietary intake and exercise according to the constipation diagnosis and treatment guidelines.

During the study, patients need to scan the two-dimensional code or search for the electronic questionnaire "Vibrabot Health" Official Account on WeChat, and fill in the relevant information during the treatment in the electronic questionnaire in a timely and truthful manner. The treatment effect of the patients is evaluated by assessing the number of occurrences of spontaneous bowel movements (SBM) and complete spontaneous bowel movements (CSBM).

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Constipation is characterized by a decrease in bowel movements, dry and hard stools, and difficulty in defecation. With changes in diet, faster pace of life, and social psychological factors, the prevalence of chronic constipation is on the rise. The global incidence of chronic constipation is 14%, while the prevalence of chronic constipation in adults in China is 4.0% to 10.0%. The prevalence of functional constipation in China is 6%. The high-risk groups for constipation include the elderly, women, diabetics, those taking opiates, antipsychotic drugs, or bedridden patients. Occupation, lifestyle, dietary habits, mental health, family history of constipation, and BMI are factors related to constipation.

Constipation affects patients' quality of life, and some patients abuse laxatives or repeatedly seek medical treatment, increasing medical costs. The main treatments for constipation are adjusting lifestyle, medication, psychotherapy, biofeedback, and surgery. However, these methods often have side effects, and patient satisfaction is still relatively low. A new approach needs to be explored to address this clinical problem.

The Disposable Gastrointestinal Vibrating Capsule System (Vibrabot capsule) (NMPA Device Approval No. 20223090282) is the world's first approved and marketed product for treating constipation through purely physical means. It can provide intermittent comfortable massages to the digestive tract, activate the intestinal neural network, awaken intestinal motility, and help alleviate constipation issues. Clinical study results show that the product is safe to use and can increase the frequency of bowel movements in patients with chronic functional constipation.

This study focuses on post-marketing clinical study for patients with functional constipation of varying severity, further evaluating the efficacy of the product in a large sample population.

Through this real-world study, to analyze the response of functional constipation patients with different severity, treatment status, capsule dosage, and combined medication to Vibrabot capsule, as well as the duration of efficacy maintenance during the follow-up period; to compare the efficacy with patients treated with drugs or other therapies during the same period, explore the possibility of curing functional constipation patients, further improve the treatment satisfaction of constipation patients, and promote the establishment and application of consensus or guidelines for the use of Vibrabot capsule in treating functional constipation.

Each patient will undergo a series of study visits, including screening, treatment visit, and follow-up visit. The visit process is briefly described as follows:

Visit 1 (0 \~ 1 day) - Baseline/Screening Period:

This visit includes:

The patient will sign an informed consent form; Set the inclusion/exclusion criteria; Guide patients to fill out the questionnaire using the Official Account and complete the Baseline Period Questionnaire in the Official Account.

Prescription Vibrabot capsule treatment or other treatment options.

Visit 2 (Week 2 ±3 days) - Treatment Period 1:

This visit includes:

Fill out the Daily Bowel Movement Questionnaire in the WeChat Official Account every day, take Vibrabot capsules on time or opt for other treatment plans; Fill out the Constipation Symptom Self-Assessment Scale and Assessment Scale for Quality of Life with Constipation in the Official Account every 2 treatment weeks.

Record adverse events and concomitant treatments; Prescription Vibrabot capsules or other treatment options. Visit 3 (Week 4±3 days) - Treatment Period 2

This visit includes:

Fill out the Daily Bowel Movement Questionnaire in the WeChat Official Account every day, take Vibrabot capsules on time or opt for other treatment plans; Fill out the Constipation Symptom Self-Assessment Scale and Assessment Scale for Quality of Life with Constipation in the Official Account every 2 treatment weeks.

Record adverse events and concomitant treatments; Prescription Vibrabot capsules or other treatment options. Visit 4 (Week 6 ±3 days) - Treatment Period 3

This visit includes:

Record adverse events and concomitant treatments.

Visit 5 (Week 10±3 days) - Follow-up Period:

This visit includes:

Fill out the Daily Bowel Movement Questionnaire in the WeChat Official Account every day; Fill out the Constipation Symptom Self-Assessment Scale and Assessment Scale for Quality of Life with Constipation in the Official Account every 2 treatment weeks; Record adverse events and concomitant treatments.

Treatment with Vibrabot Capsule

Treatment with Vibrating Capsule

Intervention Type DEVICE

Main parameters of Vibrabot capsule: nominal diameter: 11.8±1mm; nominal length: 26.7±1mm; nominal weight: 4.5±1g.

After the patient swallows the Vibrabot capsule, the capsule runs through the stomach → duodenum → jejunum and ileum → colon. According to the clinical data and configuration settings, the capsule will reach the colon and vibrate 8 hours after activation for ≥ 180 minutes in a cycle at low, medium, and high frequencies sequentially. The capsule relieves and treats constipation by massaging the colon wall through motor vibration to relieve colon muscle spasms and promote colonic peristalsis.

The VC well be taken between 21:00 and 22:00 every day, and the frequency of administration is determined based on the patient's individual situation.
