Evaluation of C-Scan Capsule in Identifying Subjects With Elevated Risk of Colon Polyps

Evaluation of C-Scan Capsule in Identifying Subjects With Elevated Risk of Colon Polyps

The main objective of the study is to determine the ability of the C-Scan system to identify subjects who are at elevated risk for colon polyps. This will be evaluated by comparing the C-Scan data to colonoscopy data. The C-Scan procedure is therefore performed before the colonoscopy procedure, in order to compare these tests and evaluate the C-Scan system's effectiveness.

During the C-scan procedure, Subjects will be asked to come for an appointment in a clinic, during this appointment, the C-Scan Track will be placed on the participant's back. The participant will then be asked to swallow the C-Scan capsule whereafter they are free to continue their routine. Participants will start intake of fiber pills 5 days, and contrast agent 48 hours prior to C-Scan capsule ingestion and will continue intake up to the capsule's natural excretion.

A standard colonoscopy procedure will be performed within 60 days following C-Scan Cap ingestion.

Inclusion Criteria:

1. Subjects 45-75 years old
2. Able to provide a signed informed consent.
3. Willing and able to comply with the specified study requirements and can be contacted by telephone.
4. Scheduled for colonoscopy procedure no later than 60 days after C-Scan ingestion
5. Maximal abdominal circumference < 125 cm.

Exclusion Criteria:

1. Subject who is not a suitable candidate for a colonoscopy

2. Known history of dysphagia or other swallowing disorders.

3. History of the following:

   3. Delayed gastric emptying.

5. Known IBD (Crohn's, Ulcerative Colitis)

6. Prior history of gastrointestinal tract surgery.

14. Known condition which precludes compliance or is contraindicated with study and/or device instructions.

15. Any procedure requiring contrast agent, or which may introduce electronic interference (such as magnetic resonance imaging, DEXA scan) or an imaging procedure pre-scheduled within 14 days of C-Scan ingestion

16. Nuclear imaging procedure within the four (4) weeks preceding the C-Scan procedure.

17. Known condition of opioid use disorder and/or alcoholism.

18. Women who are either pregnant or nursing at the time of screening (to be verified by urine or serum pregnancy test for woman of child- bearing potential who are not post-menopausal or undergone surgical sterilization).
