CE Marked Multiplex PCR Assay for Detection of Parainfluenza Virus

ProParaflu+™ joins ProFlu+™ and Pro hMPV+™ in Prodesse´s series of real-time
molecular assays for respiratory virus detection

The ProParaflu+™ Assay is now CE marked for European and other customers outside the US. It is also now available in the US as a Research Use Only product for non-clinical use. ProParaflu+ rapidly and accurately detects and differentiates 3 strains of parainfluenza virus. The two most common currently used methods of detection have serious shortcomings. DFA (direct fluorescent antibody) lacks sensitivity and requires a subjective determination.

Culturing for respiratory viruses is a slow process - from a few days to 2 weeks - and, while more sensitive than DFA, respiratory viral culturing is generally less sensitive than well-designed molecular methods. The real-time PCR technology used in ProParaflu+ makes the detection process far more effective than other methods, yielding answers in as little as 3-4 hours.

Parainfluenza 1 virus is the leading cause of croup in children, while parainfluenza 3 virus is more commonly associated with bronchiolitis and pneumonia. The highest rates of serious illness from the parainfluenza viruses occur among children. Parainfluenza is second only to respiratory syncytial virus (detected by ProFlu+) as a cause for hospitalization of pediatric patients, causing perhaps 100,000 pediatric hospitalizations annually. The parainfluenza viruses have also been implicated in pneumonia and other respiratory illnesses in adults; the elderly and immunocompromised being particularly at risk.

Prodesse Chief Marketing Officer Andy Shrago commented, 'We have been very pleased with the performance of our ProParaflu+ Assay, and our clinical trial sites have all reported the product is very user-friendly. As expected, the clinical trials sites have detected a substantial number of parainfluenza 3s in the summer, therefore this assay will be highly useful year-round. We expect to complete our US clinical trials in early 2009 and anticipate submission for FDA 510(k) clearance next Spring.'

ProParaflu+ joins the FDA-cleared ProFlu+ and FDA-clearance-pending Pro hMPV+ as the third member of the 'plus' family, a series of products using the same internal control so that a single nucleic acid extract may be used in the most appropriate way for respiratory pathogen testing for each particular facility and patient. The fourth member, ProAdeno+™, for adenovirus, is currently in development.
