Evaluation of Check-Cap C-Scan System in Providing Structural Information and Detection of Polypoid Lesions

Study Overview
=================
Brief Summary
-----------------
The purpose of this study is to establish the efficacy of Check-Cap's C-Scan System in providing structural information on colonic polypoid lesions and masses, as an adjacent tool to FIT.

Detailed Description
-----------------
The subject will be invited to come to the clinic to sign the ICF and other related documents. Then they'll ingest the capsule typically during the morning hours. The subjects will be connected to the C-Scan Track and system's activation the subject will be asked to ingest the C-Scan Capsule with some water and contrast media, in the presence of a physician. Post ingestion, the subject will be discharged home with clear instructions on the procedure. The subject should avoid intensive physical exercise during procedure or any extreme activities. The subject should make an effort to stay at home or other familiar surroundings, and may continue daily activities such mobile/computer/TV use, shower, sleep or eat. Details on allowed and restricted activities are listed in app. 4 The subject will be required to ingest daily dose (3 X 15-17ml) of contrast media, to be consumed three times per day with normal diet. Also on a need based the subject would be provided with laxadine (5 mg tablets) to be ingested according to the doctor recommendation. During capsule procedure the subjects will be contacted by phone several times daily by the site clinical study team (or by dedicated external trained medical personnel), to assure the subjects well-being and to monitor for any change or discomfort and for procedure progress. Subjects may be also monitored by the technical team (either at home or at the clinic), who may need to examine the system or inquire the subjects about the system visual/auditory indicators. The subjects will be provided with a dedicated capsule collection kit, to assist the subjects in collecting the capsule. Subjects will be instructed to retrieve the capsule upon excretion. Capsule procedure is completed upon capsule excretion or system vibro/auditory indication of 'End of Procedure'. Patients will be instructed to return the C-Scan Capsule and C-Scan Track to the clinic for analysis. All subjects will be scheduled for optical colonoscopy to be performed within one month following capsule procedure. C-Scan Procedure Analysis: Two to three licensed gastroenterologist physicians, will be trained with reviewing and analyzing C-Scan System scans, to serve as independent reviewers. A reviewing forum consisting of at least one independent trained gastroenterologist physician and at least 2 expert Check-Cap reviewers that will jointly review all the cases. The reviewing forum will be blinded to the FIT and colonoscopy results of the examined patients..). Analysis will be performed on a per patient basis for the existence or non-existence of a finding that may be a polyp. This per patient finding will be compared with the FIT, and a colonoscopy will be performed for verification.

Intervention Model: Parallel Assignment
Masking: Double


Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Active Comparator: Up to 45 subjects<br>Subjects with known polyp lesions≥10mm which were not removed because of poor preperation or the need to perform polypectomy at hospital will ingest the C-Scan cap and then will be schduled to polypectomy. The subjects will perform FIT test during the procedure and it will be compared with C-Scan System results. | Device: C-Scan System<br>* To establish the efficacy of C-Scan Capsule System and FIT in detecting patients with polypoid lesions ≥ 10mm, compared with Optical Colonoscopy To evaluate the safety of the C-Scan Capsule System procedure<br>* Other names: Colon capsule;|
| Experimental: Up to 25 subjects<br>Subjects who were reffered to screening colonoscopy as an average risk for CRC will ingest the C-Scan cap and then will be schduled to polypectomy. The subjects will perform FIT test during the procedure and it will be compared with C-Scan System results. | Device: C-Scan System<br>* To establish the efficacy of C-Scan Capsule System and FIT in detecting patients with polypoid lesions ≥ 10mm, compared with Optical Colonoscopy To evaluate the safety of the C-Scan Capsule System procedure<br>* Other names: Colon capsule;|
