– Prospective Multi-Center Trial to Enroll Over 2,000 Clinical Samples –
Curetis AG today announced the start of a clinical trial of its Unyvero™ System and the corresponding LRT (lower respiratory tract) application in the U.S. The company expects enrollment completion within the next 12-15 months, followed by a 510(k) submission to the FDA in 2014.
The prospective, multicenter trial will include samples collected from more than 2,000 hospitalized patients suspected to have a lower respiratory tract infection and several hundred retrospective samples with known microbiology culture results for rare pathogens. Samples will be processed by the Unyvero™ Lysator, transferred to the LRT cartridge, and tested by the Unyvero™ Analyzer.
Primary endpoint of the study will be assay performance defined as clinical sensitivity and specificity compared to microbiology culture (today’s diagnostics standard of care) and to a composite reference diagnosis that incorporates PCR and sequencing to determine clinical truth whenever microbiology culture results are negative.
Trial sites include Northwestern University (Chicago, IL) and North Shore-LIJ Health System (Lake Success, NY), among others. The Principal Investigator is Prof. Christine C. Ginocchio, Senior Medical Director and Chief, Division of Infectious Disease Diagnostics, North Shore-LIJ Health System. Curetis has contracted Aptiv Solutions as its CRO and Neil Mucci of GlobalBioclinical as project manager in the US.
The LRT application analyzes 39 DNA targets simultaneously from a single patient sample. Results are available within about 4 hours. The pathogen panel has been selected for clinical relevance based on current international clinical guidelines and has been reviewed by clinical experts in Europe and the USA. Resistance genes were chosen by frequency and clinical significance. A similar product, the Unyvero™ P50 pneumonia cartridge is CE-marked and currently marketed in Europe and the Middle East.
