Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Subjects will be healthy participants scheduled for routine colonoscopy. Baseline blood work will be collected within 30 days of the procedure. On the day of the scheduled colonoscopy the principal investigator will insert the Suono Calm device (low-frequency ultrasound probe) and instill a mesalazine enema (4g/60mL suspension) through the device port. A 2 minute ultrasound treatment will be activated. The device is removed and the enema is to be evacuated. A fleet enema will be administered immediately after to rinse out residual mesalazine. The process, including mesalazine enema, ultrasound treatment, and fleet enema, is expected to take no more than 5-10 minutes. Participant will be requested to complete a 5 minute questionnaire rating the experience. Participant will proceed with the colonoscopy for visual observation and collection of 4 colon tissue biopsies. Biopsies will be used for histological analysis and drug concentration for study endpoints. One hour after mesalazine enema, final blood work will be collected. The entire procedure will be conducted at a clinic by the trained principal investigator following an approved protocol and case report forms including procedure checklist.
A brief follow-up call will be conducted 3-7 days after the procedure.
