Technical Feasibility Evaluation of Mucosal Staining During Colon Capsule Endoscopy (CCE) Procedure in Colorectal Cancer (CRC) High Risk Population, When Using MB-MMX

Not Applicable

Completed

Conditions: Polyp, Colonic
Colorectal Cancer

Interventions: Device: PillCam Colon2 procedure with MB-MMX

Registration Number: NCT05022719

Lead Sponsor: Medtronic - MITG

Brief Summary: A prospective, single-center, single-arm, non-randomized, post-market pilot study evaluating the technical feasibility of mucosal staining during COLON2 Capsule Endoscopy (CCE) procedure in population at high risk for Colorectal Cancer (CRC), when using MB-MMX (Methylene Blue).

Up to 15 subjects will be enrolled in 1 center located in Spain. Study duration- up to 10 months from study approval.

Detailed Description: Single-center, prospective, non-randomized clinical trial designed to evaluate the technical feasibility during CCE procedure, when using MB-MMX as a contrast- enhancement technique of mucosal staining in CRC high risk population.

Subjects will undergo a bowel preparation (single dose, 4L PEG), including 200 mg Methylthioninium chloride, corresponding to eight 25 mg MB-MMX tablets and 1 tab of Resolor (Prucalopride 1mg). An experienced Gastroenterologist will read the CCE procedure and complete a subjective questionnaire, to evaluate mucosal enhancement during a CCE procedure, when using MB-MMX as a contrast-enhancement technique.

Primary Outcome Measures

Name	Time	Method
The Percent of Colonic Polyps Which Have a Visible Contrast to the Healthy Colonic Mucosa During Colon Capsule Endoscopy (CCE)	During the CCE procedure	The percent of colonic polyps which have a visible contrast to the healthy colonic mucosa during CCE, as indicated by an experienced reader, using the subjective reader questionnaire (For each polyp - was there a contrast between the polyp and the healthy mucosa? Yes/No), out of the examined polyps
The Interference Level of Detrimental Effects on the Visualization of the Colonic Mucosa During Colon Capsule Endoscopy (CCE), Due to Use of MB-MMX Per Colonic Segment.	During CCE	The interference level of detrimental effects on the visualization of the colonic mucosa during CCE, due to use of MB-MMX per colonic segment. Detrimental effect will be considered as any observation, such as an excessive blue dye deposit, dark and dim appearance of the tissue, interfering with tissue visualization and will be evaluated on a scale from 1 (no interference) to 5 (high interference) to evaluate the level of interference, using a subjective reader questionnaire.

Secondary Outcome Measures

Name	Time	Method
To Evaluate the Safety of CCE Procedure While Using MB-MMX.	Evaluated for each patient enrolled from day -1 prior to the procedure (start of bowel prep intake) until day 5-9 after the procedure (end of follow-up).	All AEs will be reported by number, type, relatedness (device/procedure), seriousness, severity and duration. All AEs will be captured, regardless of severity.
