Brief summary

The primary aim of this study is to evaluate the efficacy and safety of Danning Tablets in the treatment of MGPs. Specifically, the study seeks to determine whether Danning Tablets, when used alongside standard care, can effectively reduce the size of MGPs and improve related symptoms.

Detailed description

Study design: The study will be conducted in phases over a 6-month period, with participants being randomly assigned to either the intervention group (receiving Danning Tablets plus standard care) or the control group (receiving standard care alone). The study will involve multiple follow-up visits for participants at key intervals: baseline (in-person visit), and then follow-ups at the 4th week (telephone), 8th week (telephone), 12th week (in-person), and 24th week (in-person). Endpoints: Primary endpoints: Clinical efficacy rate at the 24th week following medication commencement Efficacy is determined based on the proportion of patients who experience a reduction in the size of the largest polyp or complete polyp resolution, as assessed by ultrasound. Secondary Endpoints: 1. Symptom Relief Rate: This rate evaluates the improvement in symptoms such as abdominal distension, nausea, anorexia, upper right abdominal pain, and radiating right shoulder pain. Improvement is measured using the Visual Analogue Scale (VAS) scores, with a decrease in score indicating symptom relief. 2. Disease Progression Rate: Assessed by the increase in the size of the largest polyp (≥2 mm in diameter) 3. Incidence of Adverse Events/Reactions

Interventions

5 tablets per time, 3 times daily, taken orally after meals

Intervention model description

Target population: Patients with multiple gallbladder polyps. Intervention and comparison: 1. Intervention Group: receiving Danning Tablets (5 tablets per time, 3 times daily) plus lifestyle intervention from baseline to week 12±1 after randomization, followed by 12-week lifestyle intervention. 2. Controlled Group: lifestyle intervention alone post randamization to week 24±1 Lifestyle intervention includes dietary advice to avoid cold, spicy, sour, and other irritating foods, abstain from smoking and alcohol, and to avoid excessive fatigue and emotional stress. A regular, low-fat, low-calorie diet is recommended, along with a consistent and timely eating schedule.

Inclusion criteria

Participants suitable for enrollment in this study must meet all of the following criteria: 1. Adults aged 18-75 years, both male and female. 2. Diagnosed with multiple gallbladder polyps (≥2 polyps) based on ultrasound examinations within 2 weeks before enrolment, with largest polyps measuring between 3 mm and 7 mm in diameter. 3. Participants with non-specific or without symptoms related to gallpladder polyps, such as ventosity, nausea, anorexia, right upper abdominal pain, and right shoulder radiating pain, etc. 4. Ability to understand and willingness to sign a written informed consent document.

Exclusion criteria

Participants who meet any of the following criteria will not be eligible for inclusion in this study: 1. Clinical diagnosis of gallbladder cancer, and/or gallbladder/bile duct stones, and/or acute cholecystitis. 2.

Design outcomes

Primary

MeasureTime frameDescription
Clinical Efficacy RateFrom enrollment to the end of treatment at 24 weeksThe primary measure is the clinical efficacy rate at the 24th week following medication commencement. Efficacy is determined based on the proportion of patients who experience a reduction in the size of the largest polyp or complete polyp resolution, as assessed by ultrasound. A. Cure: Disappearance of polyps upon re-examination. B. Effective: Reduction in the maximum diameter of the largest polyp. C. Ineffective: No change or increase in the maximum diameter of the largest polyp. Clinical Efficacy Rate: Defined as the proportion of patients who are cured or show effectiveness (Cure+Effective) over the total number of patients.

Secondary

MeasureTime frameDescription
Symptom Relief RateFrom enrollment to the end of treatment at 24 weeksThis rate evaluates the improvement in symptoms such as abdominal distension, nausea, anorexia, upper right abdominal pain, and radiating right shoulder pain. Improvement is measured using the Visual Analogue Scale (VAS) scores, with a decrease in score indicating symptom relief.
Disease Progression RateFrom enrollment to the end of treatment at 24 weeksThe proportion of patients with an increase in the size of the largest polyp (+2 mm in diameter) over the total number of patients.
Incidence of Adverse Events/ReactionsFrom enrollment to the end of treatment at 24 weeksMonitoring and reporting of any adverse events or reactions during the trial
