OpGen Group Company Ares Genetics Advances ares-genetics.cloud Platform, Presents Update at Scientific Conferences, Expects Granting of Key Patent

Extended collaboration with leading global generics company Sandoz for optimal antibiotic drug positioning by predictive antibiotic susceptibility testing

Presenting study on combining ares-genetics.cloud with long-read sequencing for rapid antibiotic susceptibility testing in collaboration with Johns Hopkins researchers

Expects granting of key patent on genetic resistance prediction against antimicrobial drugs

GAITHERSBURG, Md. and VIENNA, Austria, Dec. 01, 2020 (GLOBE NEWSWIRE) — OpGen, Inc. (Nasdaq: OPGN, “OpGen”), announced today that its group company and wholly owned subsidiary Ares Genetics GmbH (Vienna, Austria; “Ares Genetics”) has extended its collaboration with Sandoz within its pharma partnering program. Also, Ares Genetics expects to present advances of its research use only (RUO) based ares-genetics.cloud platform for predictive antibiotic susceptibility testing (AST) at various scientific conferences and expects granting of key patent on genetic resistance prediction.

Ares Genetics and Sandoz, the #1 supplier of generic antibiotics globally, have extended their collaboration under a strategic collaboration agreement with the overall goal to develop a digital anti-infectives platform combining established microbiology laboratory methods with advanced bioinformatics and artificial intelligence methods to support drug development and life cycle management. The next phase of the collaboration aims at further leveraging molecular predictive AST and follows the presentation of final results from the initial collaboration phase on optimal positioning of fosfomycin and fosfomycin combination therapies by molecular antibiotic susceptibility testing and in silico modeling at the Antimicrobial Resistance – Genomes, Big Data and Emerging Technologies virtual conference in early November of this year.

Recent advances of Ares Genetics’ ares-genetics.cloud platform enabling accurate and rapid next-generation sequencing (NGS)-based AST using Oxford Nanopore Technology long-read sequencing are scheduled to be presented at the virtual Sequencing, Finishing and Analysis in the Future Meeting, from December 1 to 3, by Ares Genetics’ Head of Bioinformatics & Analytics Dr. Stephan Beisken, who leads the development. In addition, data is scheduled to be presented at the ASM Conference on Rapid Applied Microbial Next-Generation Sequencing and Bioinformatics Pipelines, from December 7 to 11 by, Dr. Patricia Simner from Johns Hopkins Medicine, who collaborates with the Ares Genetics team on developing next-generation sequencing based antibiotic susceptibility testing solutions.

Alongside these latest technology development achievements, Ares Genetics has further expanded its intellectual property (IP) portfolio and technology position in data-driven infectious disease diagnostics and recently received communication that the examining division of the European Patent Office intends to grant a European patent for European Patent Application No. 16 751 551.9 “Genetic resistance prediction against antimicrobial drugs in microorganism using structural changes in the genome.”

“We’re thrilled about our continued progress in developing and commercializing much needed solutions for rapid predictive antibiotic susceptibility testing using next-generation sequencing as well as the growing demand for our testing-as-a-service and interpretation-as-a-service offerings enabled by patent-pending AI-powered technology,” commented Dr. Andreas Posch, CEO Ares Genetics. He added, “I am particularly excited about our collaboration with Sandoz on optimal antibiotic drug positioning based on molecular testing as well as our joint work with Johns Hopkins demonstrating feasibility of accurate AST prediction using long-read sequencing technology as this technology could potentially allow for rapid predictive AST directly from native patient samples.”
