Study Period : From the protocol approval date (institutional review board, IRB) 24 Months
Investigational product :
Investigational Products DWJ1609 (sodium sulfate potassium sulfate, Magnesium Sulfate Anhydrous , simethicone, sodium picosulphate)
Control Products DWC202304 (sodium sulfate potassium sulfate, Magnesium Sulfate Anhydrous , simethicone)
Target Diseases : A person who needs treatment before colonoscopy (X-ray, endoscopy)
Number of Subjects : 214 Subjects in total (85 subjects per group, 2 groups in total, considering a 20% dropout rate)
详细描述
Study Methodology :
Test subjects evaluated as suitable for participation in clinical trials are randomly assigned at a 1:1 ratio to the test group (DWJ1609) and the control group (DWC202304), and clinical trial drugs are distributed for each administration group.
Subjects take the distributed clinical trial drugs as split-dose in the early evening of the day before colonoscopy (Day 1) and in the morning of the day of examination (Day 2) Test subjects visit the clinical trial institution after completing all clinical trial drugs at least 2 hours before colonoscopy (Visit 2).
All test subjects undergo colonoscopy in the morning, and the tester takes an image of all colonoscopy processes according to a separate manual.
For safety evaluation, subjects will conduct a phone visit 2 days after colonoscopy (±1 day) (Visit 3) and a regular visit 7 days after (±1 day) (Visit 4). If additional confirmation is required in the electrocardiogram or laboratory test results at the discretion of the tester, a follow-up visit can be conducted after 28 days (±2 days) (Visit 5).
