Clinical Trial Summary

The PeerScope System consists of Peer Medical camera heads, endoscopes, video system, light source and other ancillary equipment. The system is intended for endoscopic diagnosis, treatment and video observation of the digestive tract. The PeerScope system model B is indicated for use for endoscopy and endoscopic treatment within the lower digestive tract (including the anus, rectum, sigmoid colon, colon and ileocecal valve) of adults patients.

Objective:To compare the additional diagnostic yield obtained by using the PeerScope System™ extended view vs. the diagnostic yield obtained by the Standard view colonoscopy.

In addition, time measurements including time to cecum, time for withdrawal and overall procedure time will be analyzed and reported for each group.

Description:

Design:

Patients who are scheduled for screening, surveillance or diagnostic colonoscopy will be recruited to the study and randomized to one of two groups. Each enrolled subject will undergo two "back-to-back" procedures.

Subjects in Group A (study group) will undergo a Standard view colonoscopy followed immediately by a PeerScope System™ extended view colonoscopy. Subjects in Group B (control group) will undergo a PeerScope System™ extended view colonoscopy followed immediately by a Standard view colonoscopy.

Results from the two groups will be analyzed and compared, with primary outcome measures being detection rates for total polyps and detection rates for adenomas. Secondary outcome measures will include withdrawal time, total procedure time and characteristics of polyps detected, including size and histological results.

Subjects will be followed through a 24 hour and a 7 days telephone interview for analysis of unexpected adverse events. Clinical results will be analyzed using various statistical measures of significance.

Study Design:

Multi-center study with up to 196 patients. No. of Patients:

Up to 196 treated patients will be enrolled into the study. Primary Performance Endpoint:

• Standard view colonoscopy adenoma overall detection rate compared to the extended view overall adenoma detection rate using the PeerScope System™

• Standard view colonoscopy overall polyp detection rate compared to the extended view overall polyp detection rate using the PeerScope System™.

Safety Analysis:

Incidence of device-related and procedure-related serious adverse events. Incidence of complications using PeerScope System™

Known complications include:

• Perforation;

• Severe abdominal pain;

• Infection;

• Bleeding (other than expected minor bleeding due to therapeutic procedures e.g. polypectomy);

• Inducing inflammation of diverticulum

• Arrhythmia, bradycardia, hypotension, hypoxia

• Death

Secondary Endpoints / Other Outcomes:

1. Performance of therapeutic interventions, such as biopsies, polypectomies, APC etc.

2. Procedure time. The following will be recorded: a. Time for intubation to the cecum. b. Time for withdrawal from the cecum to the anal verge. c. Total procedure time A stopwatch will be used for stopping the timing of the procedure for any polypectomy performed and then restarting once the polypectomy is completed, meaning that purely procedure time is measured

3. Sedation dosage

4. Patient satisfaction. Patient's pain at the end of the procedure will be recorded using VAS scale. Results of 24 hour telephone follow-up to assess for post-procedural patient satisfactory will be recorded on the CRF.

Inclusion criteria:

• Subject between the ages of 18 and 70

• The patient is undergoing colonoscopy for screening, for surveillance in follow-up of previous polypectomy or for diagnostic workup;

• Written informed consent must be available before enrollment in the trial

• For women with childbearing potential, adequate contraception

Exclusion criteria:

• Patients with a history of colonic resection;

• Patients with known (or newly diagnosed) inflammatory bowel disease;

• Patients with a personal history of polyposis syndrome;

• Patients with suspected chronic stricture potentially precluding complete colonoscopy;

• Patients with diverticulitis or toxic megacolon;

• Patients with a history of radiation therapy to abdomen or pelvis;

• Patients with acute lower GI bleeding

• Patients who are currently enrolled in another clinical investigation in which the intervention might compromise the safety of the patient's participation in this study.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	polyp detection rate	Sample size calculation is based on detecting a difference in the adenoma overall detection rate and the overall polyp detection rate using the PeerScope System™ extended view as compared to Standard view colonoscopy.; Total sample size will be 196 patients. Each patient will undergo the procedure by the two devices: PeerScope System™ extended view and Standard view colonoscopy. The rational for this sample size is based on detecting a rate difference of 20% between the study devices.	1 year	No
