Company News: Curetis Initiates Next Phase of Unyvero U.S. FDA Trial in Lower Respiratory Tract Infections
– First patient enrolled in prospective arm of IVD trial
– Study to include a total of at least 2,500 patient samples
– Milestone triggers payment of EUR 6.8 million financing tranche
Curetis AG, a developer of next-level molecular diagnostic solutions, today announced the enrollment of the first patient in the prospective phase of its Unyvero U.S. FDA trial.
The primary endpoint of the multicenter U.S. study will be the performance of Curetis’ second generation Unyvero Lower Respiratory Tract (LRT) cartridge, LRT55, in detecting lower respiratory tract infections as compared to microbiology culture – which is currently considered the diagnostic standard of care. In addition, Unyvero results will be compared to an independent molecular composite comparator based on pathogen DNA analysis by PCR and sequencing. At least eight trial sites across the U.S. will participate in the at least 2,500-patient study.
The new trial phase is based on an augmented study design and an enhanced product. This phase of the U.S. trial incorporates two new elements: the latest FDA guidelines for diagnostic trials, and modifications resulting from outcomes of the first phase of this trial. Enrollment completion is anticipated in mid-2016 with FDA submission targeted for the second half of 2016. The Company aims for FDA clearance for Unyvero and subsequent commercialization in early 2017.
The continuation of the trial triggers a EUR 6.8 million financing tranche supported by current Curetis investors.
LRT55 is a second-generation cartridge based on the design of the CE-IVD marked P55 cartridge marketed outside the U.S. It features 40 markers and a novel control concept with live bacteria in the control material and improved representation of pathogens in the panels. As a result, it provides the most comprehensive molecular marker panel for LRT infections marketed today. P55 has demonstrated superior performance in the CE performance evaluation study and additional investigator-initiated clinical studies.
In the U.S. FDA trial, tracheal aspirates and bronchial lavages will be pre-processed by the Unyvero Lysator and transferred to the Unyvero LRT55 cartridge, which is subsequently analyzed by the Unyvero Analyzer. Results are available within four-to-five hours.
The prospective arm of this trial includes at least 1,500 hospitalized patients with suspected lower respiratory tract infections to determine the clinical specificity of the Unyvero LRT55 cartridge.
In another arm of the study, at least 1,000 retrospective blinded patient samples will be analyzed for clinical sensitivity endpoints. All pathogens and resistance markers featured on the Unyvero LRT55 Cartridge will be included in the study. Already, Curetis has collected more than 500 retrospective patient samples across its clinical trial network. All retrospective samples have been tested positive for pathogens on the LRT55 panel by standard microbiology culture.
