U.S. FDA Approves "Vstrip", IVD for Rapid Diagnosis of H. pylori Infection

Germantown, MD, USA (April 19, 2019) – Amarex Clinical Research, LLC learned that, on March 14, 2019, the US FDA approved a new rapid in vitro diagnostic (IVD) kit, Vstrip, for detection of H. pylori infection. Vstrip is a single use immunochromatographic assay for the qualitative detection of H. pylori antigens developed and produced by Panion & BF Biotech Inc. (PBF), a Taiwan-based biopharmaceutical company. This product successfully completed clinical trials at several medical research centers and sites in the United States and Taiwan, and the data proved to be consistent with the comparator and gold standard.

Amarex’s clinical team designed the trials and managed clinical performance of the studies in the U.S. and Taiwan. In addition, Amarex’s biometrics and regulatory departments worked together on the data analysis and the preparation of the 510(k) application. The President & CEO of Amarex Clinical Research, Dr. Kazem Kazempour stated that, “We worked closely with our client to initiate this development by completing a pre-submission meeting with the U.S. FDA last July, and by adhering to FDA recommendations. As a result, the 510(k) studies preparation and approval application were finished within five months, leading to Vstrip’s rapid 510(k) approval. This accomplishment demonstrates Amarex’s capacity for successful collaboration and highlights our strength in product development.”

Currently, a large U.S. IVD kit manufacturer has developed a similar product with a market value of $60 million. Compared to the available products on the US market, Vstrip enhances the convenience of usage and increases its competitiveness. The approved Vstrip can now be used for clinical applications, in addition to research uses. PBF is looking for U.S. distribution partners to sell the IVD in the U.S. market.
