A Study of Danning Tablet in Patients With Polypoid Lesions of Gallbladder

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:

• 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.
• Disease Progression Rate: Assessed by the increase in the size of the largest polyp (≥2 mm in diameter)
• Incidence of Adverse Events/Reactions

Inclusion criteria

Participants suitable for enrollment in this study must meet all of the following criteria:
