Otsuka Pharmaceutical Co., Ltd. Announces FDA Clearance for the RAPIRUN(R) H. pylori Antibody Detection Kit

TOKYO, Nov. 27 (HSMN NewsFeed) -- Otsuka Pharmaceutical Co., Ltd. (Head Office: Tokyo, Japan; president: Tatsuo Higuchi; Phone: +81-3-3292-0021) today announced that the company received U.S. Food and Drug Administration (FDA) clearance on November 16th, 2006 for its 510(k) application to market the RAPIRUN® H. pylori Antibody Detection Kit (RAPIRUN® Kit), the first test available in the U.S. market to detect anti-H. pylori IgG antibodies in urine.

Otsuka has become a leader in the field of H. pylori diagnostics. Additional Otsuka family technologies related to H. pylori include the BreathTek(TM) UBT (13)C-urea breath test for determination of H. pylori infection, and the UBiT®-IR300 and POCone(TM) Infrared Spectrophotometers for measurement of (13)CO(2) level in breath. These products are marketed in the U.S. by Meretek Diagnostics, Inc. (Lafayette, Colo.), a subsidiary of Otsuka Pharmaceutical Co., Ltd.

The RAPIRUN® Kit is a rapid immunochromatographic assay intended for the qualitative detection of antibodies against H. pylori in urine to aid in the diagnosis of H. pylori infection. The kit is suitable for use in both point-of-care and clinical laboratory settings. The test is easy to administer, economical and convenient for the patient.

Noninvasive testing for screening of H. pylori infection is preferred over methods that require endoscopy. Approximately 81% of dyspeptic patients presenting to primary care receive noninvasive testing in the U.S. Options include testing for specific anti-H. pylori IgG antibodies, urea breath tests (UBTs) and stool antigen tests.

The RAPIRUN® Kit has been developed as an in vitro diagnostic device employing the immunochromatographic method that can detect low levels of anti-H. pylori antibodies in urine. The operating procedures are simple and test results can be determined by visual inspection in about 20 minutes.

Recent studies show that detecting anti-H. pylori antibodies in urine to diagnose infection is an effective alternative to blood-based antibody tests. However, the concentration of IgG in urine is far lower than it is in serum. Because of the low concentration, a highly sensitive test like the RAPIRUN® Kit is required for detection of antibodies in urine.
