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.
