Brief Summary:
This study was design to establish the effectiveness of PillCam® Platform with the PillCam® COLON 2 capsule as demonstrated by the identification of subjects with polyps as compared to optical colonoscopy.

Condition or disease Intervention/treatment Phase
CRC Screening Device: PillCam® COLON 2 procedure Procedure: Colonoscopy Not Applicable

Detailed Description:

This multi-center study was designed to evaluate the safety and effectiveness of PillCam Platform with the PillCam COLON 2 capsule as demonstrated by the identification of subjects with polyps, compared to optical colonoscopy.

884 subjects participated in this study. All subjects that were enrolled in this study were indicated and scheduled to undergo colonoscopy based on their age and demographics for screening for polyps.

Each subject was required to follow a bowel preparation regimen and to undergo capsule endoscopy (CE) followed by optical colonoscopy (OC). The optical colonoscopy procedure was scheduled 4-6 weeks after CE procedure to allow for the central readers reading of the PillCam RAPID video.

The colonoscopist was kept blinded to the CE results

Intervention Details:
  • Device: PillCam® COLON 2 procedure
    Subjects will undergo a PillCam® COLON 2 procedure which includes ingestion of the PillCam® COLON 2 capsule. PillCam® COLON 2 is a disposable, ingestible capsule that takes video images throughout the digestive system.
  • Procedure: Colonoscopy

    Subjects will undergo standard Colonoscopy procedure 4-6 weeks after PillCam® COLON 2 procedure.

    Standard colonoscopy involves placement of a standard endoscope (a thin, flexible plastic tube) into the anus and into the colon, a tiny camera in the endoscope allows the study doctor to see the surface of the colon.



Primary Outcome Measures :
  1. Sensitivity and Specificity of PillCam Platform With the PillCam COLON 2 Capsule in Detecting Patients With Polyps ≥6 mm Where OC Considered as the Gold Standard Reference [ Time Frame: 1 year, same as study duration ]

    Sensitivity and specificity of PillCam Platform with the PillCam COLON 2 capsule in detecting subjects with polyps equal to or larger than 6 mm. For a given polyp, a match between the PillCam Colon 2 Capsule and optical colonoscopy was considered if the polyp size was assessed within plus or minus 50% of the size of the estimate of the OC measurement and the polyp as appearing within the same colon segment or in adjacent segments. The polyp size measurement by optical colonoscopy was used as the reference standard.

    Sensitivity measures the proportion of actual positives which are correctly identified as such.

    Specificity measures the proportion of negatives which are correctly identified as such.

    positive event defined as patients with polyps ≥6 mm detected by OC procedure.



Secondary Outcome Measures :
  1. Sensitivity and Specificity of PillCam Platform With the PillCam COLON 2 Capsule in Detecting Patients With Polyps ≥10 mm Where OC Considered as the Gold Standard Reference [ Time Frame: 1 year, same as study duration ]
    Sensitivity and specificity of PillCam Platform with the PillCam COLON 2 capsule in detecting subjects with polyps equal to or larger than 6 mm. For a given polyp, a match between the PillCam Colon 2 Capsule and optical colonoscopy was considered if the polyp size was assessed within plus or minus 50% of the size of the estimate of the OC measurement and the polyp as appearing within the same colon segment or in adjacent segments. The polyp size measurement by optical colonoscopy was used as the reference standard.
