Clinical Trial Summary

The purpose of this study is to support the development of Given® Diagnostic System applications.

Description:

This clinical study is designed to support the development of new generations of the Given® Diagnostic System and Agile™ Patency System that will accomplish better visualization, better diagnostic capabilities and will improve the system ease of use from the physician as well as patient's point of view.

*The PillCam™ Capsules Capsule endoscopy using the PillCam™ capsule (Given Imaging Limited, Yoqneam, Israel) represents the newest imaging modality of the gastrointestinal tract without the need for invasive techniques, sedation, or radiation exposure1-35. Initially cleared for marketing in August 2001 as an adjunctive modality, the FDA in 2003 cleared PillCam™ SB (previously called M2A) as a stand alone tool for detecting small bowel abnormalities in those patients who meet the device's indications.

The PillCam™ SB provides visualization of the entire small bowel mucosa and is presently purely a diagnostic test without therapeutic or biopsy potential.

Before capsule endoscopy, enteroscopy was one of the methods for examining the small bowel tract, but the diagnostic value of this test for a wide variety of specific lesions is low due to inability to reach the entire length of the small bowel.

Other endoscopic techniques include, Sonde enteroscopy, and intraoperative enteroscopy, but these are limited for several reasons including significant technical difficulties, length of procedures, potential risks, and frequently incomplete small bowel examination36-38. To date more than 400,000 PillCam™ SB capsules were ingested world wide. The Given® Diagnostic System (GDS) for Small Bowel is now the Gold standard.

Additional PillCam™ capsules were developed and are used for diagnosing the Esophagus as well as the Colon.

The PillCam™ ESO system received FDA clearance as well as the CE mark early 2005. To date, thousands of PillCam™ ESO capsules were ingested in both clinical trials and regular clinical setup worldwide with numerous published clinical studies39-45.

The PillCam™ COLON capsule received CE marking on October 15th, 2006 and is cleared for marketing in Europe. It is now pending FDA clearance. To date, several hundreds of PillCam™ COLON capsules were ingested in numerous pilot studies and ongoing multi-center studies in Europe and USA34-35.

*The Agile™ Patency System Small and large bowel strictures are present in a large spectrum of diseases and clinical situations such as adhesion related diseases, Crohn's disease, patients who are post abdominal radiation treatment and patients who have undergone abdominal surgery46. Knowledge of intestinal patency in such patients will aid the physician in assessment and treatment of the patients.

The current methods for identifying intestinal strictures primarily include small bowel follow through (SBFT), enteroclysis, computed tomography (CT) and enteroscopy but the diagnostic value of these tests is low. Advanced strictures are often missed and some of these methods include radiation and others are invasive.

The Agile™ Patency System is designed to aid the gastroenterologist in verifying the patency of the GI tract. The system is essentially based on small identification tags, which are detected by radio frequency (RFID) encapsulated in a disintegrating capsule. The RFID tags have been marketed for many years for veterinary use. In animals they are injected sub-dermally and are used for life-long identification, marking and tracking47.

Preliminary results demonstrate that the Agile System performs as intended48. Future developments of the unique technology which make up the Agile patency capsule will broaden its range of uses and applications beyond simple patency testing.

Agile ingestions are estimated in the excess of three thousand worldwide.
