The world’s largest genomics study in patients with life-threatening COVID-19 infections has uncovered 16 new genetic variants associated with severe disease and drawn up a roadmap for research into new therapies and diagnostics. The research involved comparing the complete genome sequences of 7,491 patients admitted to 224 intensive care units in the U.K. against those of 48,400 participants in Genomics England’s 100,000 Genomes project, and of a further 1,630 people who had mild COVID-19. While some of the gene variants found in the Genomicc study affect the function of a protein, others influence the amount of the protein that is expressed. An example is mucin-1, where overexpression led to worse outcomes.

The FDA continues its tight surveillance of rapid antigen tests for the COVID-19 pandemic and has issued three safety communications advising against the use of these tests thus far in the month of March. In each instance, the test is made by the manufacturer of name, but was not authorized in the U.S., making these misbranded products despite their legal use in other nations.

While clinical trial updates in 2022 started off slow, the gap with last year appears to be closing, even as pandemic activity diminishes.

LONDON – The U.K. Recovery trial has added a fourth drug to the list of therapies it has shown are effective in treating hospitalized COVID-19 patients, demonstrating the JAK inhibitor Olumiant (baricitinib) reduces the risk of death by 13% in seriously ill patients. That effect is in addition to treatment with dexamethasone, which became standard of care after the Recovery trial showed it reduced mortality by one-third in patients on ventilators.
