Ventana Receives First FDA Clearance for H. pylori Antibody

The VENTANA anti-Helicobacter pylori (SP48) Rabbit Monoclonal Primary Antibody (H. pylori) is the first H. pylori antibody to receive 510(k) clearance from the Food and Drug Administration (FDA).

Developed by Ventana Medical Systems, Inc. (Ventana), a member of the Roche Group, the VENTANA H. pylori antibody, when used in immunohistochemical (IHC) staining, aids in the detection of Helicobacter pylori. 'FDA clearance of the VENTANA H. pylori antibody proves that our product surpasses the industry standard,' says Greg Yap, Ventana lifecycle leader for advanced staining assays. 'By leveraging our expertise in industry-leading advanced staining assays and workflow solutions, we are delivering to pathologists another next-generation tool for treating potentially cancer-causing gastric infections.´´

The VENTANA H. pylori antibody provides pathologists unprecedented views of the bacterium, allowing for a more accurate patient diagnosis. The high contrast staining of the organisms allows pathologists to view more bacteria than can be detected with special stains. With the H. pylori antibody, a pathologist can clearly view the characteristic helical shape of the organism. Even when very few organisms are present, an infection can be detected and treated effectively.

'As a pathologist with years of hospital experience, I believe our new H. pylori IHC test is an improvement to what is currently available for the diagnosis of H. pylori in tissue,' says Dr. June Clements, Ventana staff pathologist. 'The clean background and clear staining make identifying the organisms easier and faster. This, along with the specificity, provides the pathologist more confidence in the diagnosis.'

For labs, the FDA clearance means less time spent validating the assay and more time running the tests, allowing for better lab workflow and quicker, more accurate patient diagnosis. The H. pylori antibody is also fully integrated with the VENTANA BenchMark XT and BenchMark ULTRA slide staining instruments.

'The key to our success in gaining FDA clearance was working with the FDA early in the process,' says Sam Rua, director of regulatory affairs. 'We met with the FDA, agreed to an approach for our 510(k) submission and adhered to that approach every step of the process. Because of that alignment, we were ultimately successful in gaining approval for the VENTANA H. pylori antibody.'
