Cepheid (NASDAQ: CPHD) announced it has received clearance from the U.S. FDA to market its Xpert® Flu/RSV XC, an on-demand molecular test for accurate and reliable determination of Flu A, Flu B, and differentiation of RSV infection. Xpert Flu/RSV XC runs on Cepheid's GeneXpert® System, the world's leading molecular diagnostic platform with more than 7,500 systems installed worldwide.

Upper respiratory infections are one of the most common reasons for doctor and hospital visits and, in the United States, are the most common illness leading to school or work absences. Early symptoms for a wide variety of viral and bacterial respiratory infections are similar, yet treatment is different depending on the cause of infection. With Xpert Flu/RSV XC, hospitals and clinicians can be prepared to reliably diagnose and differentiate influenza strains and RSV in real-time.

"Influenza strains are notoriously unpredictable and the severity of flu outbreaks can vary widely from season to season," said John Bishop, Cepheid's Chairman and Chief Executive Officer. "Recent media coverage of serious viruses such as Enterovirus D68 and Ebola have raised public awareness, and created a greater need for healthcare workers to deliver timely and accurate test results for flu or RSV infection."

The flu is a contagious respiratory illness caused by influenza viruses that infect the nose, throat, and lungs. It can cause mild to severe illness, and at times can lead to death. Patients infected with the flu may be able to infect others beginning one day before symptoms develop and up to five to seven days after becoming sick. Some people, especially young children and people with weakened immune systems, might be able to infect others for a longer time.1

Respiratory syncytial virus (RSV) is a very common virus that leads to a wide range of respiratory symptoms in children and older adults. It can be more serious in young children, especially those in certain high-risk groups. Most infants have had an RSV infection by age two.2 RSV is the most common cause of bronchiolitis and pneumonia among infants and children under one year of age.3

Doctors Donna M. Wolk and Raquel M. Martinez, investigators at Geisinger Health System, were involved in investigational testing of Xpert Flu/RSV XC during Cepheid's product development phase. Their Microbiology Research team is planning a pilot testing program they call FluWorks©. This program aims to allow test results to be immediately delivered to physicians and patients or designated family members via electronic health records, web portal, or text messaging.

"We are anxious to understand the role that the Xpert Flu/RSV XC test can play in Geisinger's FluWorks program, designed to improve patient care, clinical operations, and laboratory stewardship. Rigorous investigational testing documented the assay's high accuracy and speed," said Dr. Wolk. "This winter, we plan to leverage the test's unique design to quickly test patients presenting with influenza-like illness at Emergency Departments, out-patient clinics, and in selected Urgent Care Clinics."

The severity of a flu outbreak can vary greatly from one season to the next depending on which flu viruses are spreading, how many people get vaccinated, and how well the flu vaccine is matched to the flu viruses that are currently causing illness.

"We employed a novel in silico approach to identify multiple complementary target segments to avoid the effects of seasonal genetic drift and to anticipate emerging novel influenza strains. Though simple to perform, Xpert Flu/RSV XC is a highly multiplexed, state-of-the-art test for fast and accurate detection and differentiation of Flu A, Flu B, and RSV infection," said David Persing, M.D., Ph.D., Cepheid's Chief Medical and Technology Officer. "This test may also become a valuable asset in efforts toward pandemic preparedness, because it was designed from its inception to provide unprecedented coverage of both human and avian influenza strains."

Supernus Pharmaceuticals, Inc. (Nasdaq:SUPN), announced the issuance of a fifth patent (number 8,889,191) by the United States Patent and Trademark Office (USPTO) covering Trokendi XR, its novel once-daily extended-release topiramate product. The patent provides protection for the product with expiration that is no earlier than 2027.

"We are very serious about securing intellectual property protection for our innovative products. This is now the second patent that issued this month on Trokendi XR. We will continue to build our patent estate to provide our products with the protection they are entitled to. We now have patent protection on Oxtellar XR® and Trokendi XR® through four and five issued U.S. patents, respectively," said Jack A. Khattar, President and CEO of Supernus.

Supernus has several additional patent applications for extended-release topiramate and extended-release oxcarbazepine pending in other geographic regions.
