LONDON – With COVID-19 infection varying in severity from asymptomatic to lethal the search is now underway for biomarkers to predict which patients are most at risk of suffering severe disease. As one possibility, Menarini Silicon Biosystems (MSB) is using its Cellsearch liquid biopsy technology to capture and count circulating endothelial cells. Meanwhile, Oxford Biodynamics plc is applying its Episwitch platform to find prognostic and predictive epigenetic markers.
The FDA has revised its emergency use authorization (EUA) policy for testing for the COVID-19 pandemic, the impact of which falls principally on serological tests for antibodies generated by the SARS-CoV-2 virus. The agency had previously allowed a commercial antibody test developer to distribute a test without submitting the validation data, but makers of such tests now must forward the validation data to the FDA within 10 days, a move prompted in part by inappropriate claims made by some test developers.
Roche Holding AG, of Basel, Switzerland, has garnered U.S. FDA authorization for emergency use of a test to determine whether people have been infected with the novel coronavirus fueling the COVID-19 pandemic. The Swiss health care giant, which also makes molecular tests to detect active COVID-19 infection, claims its Elecsys Anti-SARS-CoV-2 antibody test accurately identifies COVID-19 antibodies in the blood 100% of the time, 14 days post-infection.

With Gilead Sciences Inc. donating its existing stock of finished and unfinished remdesivir to help address the global COVID-19 pandemic through clinical trials, emergency use authorization (EUA) and compassionate use programs, patient accessibility to the investigational drug will be limited by supply, not price.
Researchers in Guangzhou, China, have developed a nanoparticle-based lateral flow immunoassay that quickly and accurately detects antibodies to the SARS-CoV-2 virus that causes COVID-19. The current test, which works in a similar manner to a pregnancy test, detects IgG antibodies in blood in less than 10 minutes. A proof-of-concept study appeared in Analytical Chemistry this week.

Bio-Rad Laboratories Inc. has launched its SARS-CoV-2 Total Ab test, which is a blood-based assay to identify all the antibodies that are developed by the human body in response to the novel coronavirus SARS-CoV-2. Companies have been racing to offer serological tests that work to detect the antibodies developed during a COVID-19 infection that remain present in the blood after the initial infection clears.
