OpGen’s Subsidiary Curetis Meets All Remaining Key Milestones in R&D Collaboration with FIND

Triggers milestone payment of approximately $0.3 million ROCKVILLE, Md., April 26, 2023 (GLOBE NEWSWIRE) — OpGen, Inc. (Nasdaq: OPGN, “OpGen” or “the Company”), a precision medicine company harnessing the power of molecular diagnostics and bioinformatics to help combat infectious disease, reported today that its German subsidiary Curetis GmbH has met the remaining key milestones under the initial research and development (“R&D”) collaboration agreement with FIND. Following the delivery of a comprehensive milestone report at the end of first quarter of 2023, FIND confirmed that all requirements have been met successfully. Under the recently announced expansion of the collaboration, the originally planned Next Generation Sequencing (“NGS”) strain analysis will be complemented with isolates from other sub-Saharan African countries. Completion of the deliverables triggered a milestone payment of approximately $0.3 million. The R&D collaboration to date has successfully addressed the development and initial wet-lab testing of a sample-in to result-out Unyvero A30 panel with 33 targets, including fully integrated sample preparation. Multiple Unyvero A30 instrument adaptations were made to optimize for use in the challenging environments of low- and middle- income countries (LMICs). Instrument prototypes have been designed, built and tested for operation in high-dust, extended temperature range and power-out scenarios. Andreas Boos, Chief Technology Officer at Curetis GmbH commented: “We are excited to have successfully delivered the final milestones from the first phase of our collaboration agreement and look forward to working on the next set of deliverables under the expanded scope of our R&D partnership with FIND.” Johannes Bacher, Chief Operating Officer of OpGen added: “We believe the successful first phase of our development collaboration puts us in an ideal position towards development of a robust solution optimized for use in LMICs, a goal we would like to pursue during a potential next phase of this collaboration under a new agreement with FIND.” Dr. Cecilia Ferreyra, Director, FIND AMR Programme remarked that, “We have evaluated the final milestone data from Curetis on the Unyvero A30 and have confirmed that the adapted prototype test meets the quality and accuracy requirements for use in low- and middle-income countries. We look forward to potential continued collaboration to expand testing for blood stream infections in LMIC hospitals so that people can be linked to the care they need as soon as possible.” About OpGen, Inc.  OpGen, Inc.
