Curetis Announces Positive Top Line Data from U.S. FDA Trial
Primary endpoint for Unyvero LRT product for lower respiratory tract infections shows overall weighted average sensitivity of 90.2% and overall weighted average specificity of 99.3% / U.S. FDA submission being prepared(lifePR) ( Amsterdam, the Netherlands/Holzgerlingen, Germany, )
The trial included a total of 2,203 prospective and retrospective samples and has run 5,694 Unyvero Cartridges, including daily positive and negative controls at each site as well as reproducibility tests. Tracheal aspirate and bronchoalveolar lavage samples were collected at nine participating sites across the U.S., namely Beaumont Health, Columbia University, Johns Hopkins, Mayo Clinic, Northwestern University, Summa Health, UCLA, University of Rochester, and University of Washington. Of these samples, 1,654 were prospectively and 549 were retrospectively tested with the Unyvero LRT Lower Respiratory Tract Cartridge, with standard of care microbiology culture and with additional molecular diagnostic assays.
Furthermore, the study will be complemented with data from more than 400 contrived samples from well-characterized pathogen strains obtained from several international strain providers. These strains were spiked into negative patient samples and are currently undergoing testing with Unyvero at several clinical trial sites in order to provide additional data points for certain rare pathogens.
Overall, more than 1,100 samples tested positive for one or more pathogens on the LRT panel. Data were available from Unyvero cartridges, from microbiology culture and from independent molecular testing using PCR and sequencing, resulting in a total of more than 350,000 data points. These data are fully consistent and in line with the performance evaluation previously conducted by Curetis for CE IVD marking in Europe, as well as published data from various European KOLs and customer sites.
Based on these data, Curetis is now preparing its final package for a 510(k) submission for the Unyvero Platform and the LRT Cartridge to the U.S. FDA in due course. The company is expecting feedback from the FDA in the first half of 2017.
"We are truly excited about completing the study on time and as planned and generating a strong and very comprehensive data set," said Dr. Oliver Schacht, CEO of Curetis. "We have now started compiling the final submission documents and are looking forward to receiving feedback from the FDA. We will be working closely with the agency in the coming months."
"This is a very broad molecular panel for diagnosis of lower respiratory tract infection," said Principal Investigator Dr. Robin Patel, Director of the Clinical Bacteriology Laboratory and Infectious Diseases Research Laboratory and Chair of the Division of Clinical Microbiology at Mayo Clinic. "It includes numerous bacteria and resistance genes as well as one fungus. Beyond panel breadth, the test yields faster results than those achieved using traditional culture."
