GAITHERSBURG, Md. and HOLZGERLINGEN, Germany, June 09, 2020 (GLOBE NEWSWIRE) -- OpGen, Inc. (Nasdaq: OPGN, “OpGen”), a precision medicine company harnessing the power of molecular diagnostics and bioinformatics to help combat infectious disease, announced today preliminary data from an investigator initiated collaboration with Karolinska Institutet, Stockholm, Sweden, to identify bacterial co-infections in hospitalized patients with COVID-19 pneumonia. The patients in this cohort had been admitted to the ICU after respiratory deterioration during hospital stay, and their lower respiratory tract samples were analyzed with the Unyvero HPN panel.
Preliminary data demonstrates that the performance of the Unyvero HPN Panel for pneumonia as compared to bacterial culture is strongly concordant (98.2%) for organism targets. In 31 out of 35 patient samples that were evaluated, Unyvero results confirmed all pathogens reported by culture. Unyvero detected additional pathogens in 7 patients, one of which was subsequently tested again by microbiological culture 7 days later and confirmed positive. These results indicate that the Unyvero system, while not always completely concordant with culture results, can detect possible pathogens which are missed by culture. Results obtained by the Unyvero Panel in five hours instead of up to several days by culture methods provides clinicians with an early organism differential, including information on antibiotic resistance markers, allowing earlier treatment decisions and support for antimicrobial stewardship efforts. Among the 35 lower respiratory specimens tested to-date, 63% were tracheal aspirate, 34% BAL/mini-BAL, and 3% sputum.
“We are pleased to share preliminary data that highlights what we already know – when it comes to managing bacterial co-infections, time is critical! Our Unyvero HPN panel provides comprehensive diagnostic information to clinicians in just a few hours, with only minutes of actual hands-on time, ensuring faster treatment decisions,” said Oliver Schacht, PhD, CEO of OpGen. “This rapid testing technology is even more important in the face of a global pandemic when time is of the essence in preventing global spread. We are encouraged by the preliminary results of our Unyvero HPN panel in Sweden and look forward to contributing testing capabilities to additional healthcare facilities around the world in the future.”
The samples were derived from patients admitted to ICUs in four acute care hospitals in Sweden – Karolinska University Hospital, Solna; Karolinska University Hospital, Huddinge; South General Hospital; Danderyd Hospital, and were taken from a patient population of SARS CoV-2-positive patients being admitted to the ICU. Patients were sampled during their hospital stay for suspected hospital-acquired pneumonia, as they were already in crowded hospitals and had experienced deterioration and inevitably requiring ventilators. Of the above-described patient population, one in four (25%) tested positive for a bacterial co-infection by microbiology.
“Although secondary bacterial infections are uncommon upon admission to hospital, these patients are at risk for hospital-acquired bacterial pneumonia, and the positivity rate is fairly high,” said Professor and Senior Consultant Physician Christian Giske, at the Department of Laboratory Medicine, Karolinska Institutet, Stockholm, Sweden. “That makes receiving test results in a matter of hours instead of days critically important. The Unyvero HPN panel empowers clinicians to make earlier treatment decisions, while supporting antimicrobial stewardship efforts, to give the best opportunity to quickly treat and manage bacterial co-infections.”
High-risk COVID-19 patients, especially in intensive care units and on ventilation, many of whom may be elderly or have preexisting conditions that compromise their immune system, are at a higher risk of acquiring bacterial co-infections that pose severe life-threatening complications. These co-infections are not always easily determined based on clinical symptoms alone, and, if they go unnoticed or diagnosis is delayed, it can lead to dire outcomes including mortality. Within this preliminary study, the median patient age was 58 years old.
The Unyvero Hospitalized Pneumonia (HPN) panel detects 21 clinically relevant pathogens and 19 antibiotic resistance markers in less than five hours directly from native specimen with only around two minutes of hands-on time, compared to routine bacterial cultures that can take up to several days for confirmatory pathogen identification and antimicrobial susceptibility testing results. In the U.S., the Unyvero LRT and LRT BAL panels for rapid detection of lower respiratory tract infections such as pneumonia are FDA-cleared for tracheal aspirate samples and bronchoalveolar lavage fluids, respectively. Unyvero HPN and LRT BAL are the only syndromic pneumonia panels that also include Pneumocystis jirovecii, a key fungal pathogen often found in immunocompromised patients that can be difficult to diagnose.
