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

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

The purpose of the first part of the study (subgroup R&D) is to demonstrate the safety and performance of the C-Scan system and to collect data in order to improve the analysis process. The purpose of the second part of the study (subgroup pre-pivotal) is to determine the ability of the C-Scan System to identify elevated risk subjects

Inclusion Criteria:

5. Maximum body (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.

   Third (3rd) and fourth (4th) exclusion criteria are applicable to the pre-pivotal subgroup only:

3. History of the following:

   • Previous colon polyps

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

15. Has 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 during 4 weeks before 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(
