Tocilizumab: No benefit

Tocilizumab was not effective for preventing intubation or death in moderately ill hospitalized patients with Covid-19. This is the result of a randomized, double-blind, placebo-controlled trial involving SARS-CoV-2 patients with hyperinflammatory states and at least two of the following signs: fever (body temperature >38°C), pulmonary infiltrates, or the need for supplemental oxygen in order to maintain an oxygen saturation greater than 92%. John H. Stone and colleagues (for the BACC Bay Tocilizumab Trial Investigators) conclude that their data do not provide support for the concept that early interleukin-6 receptor blockade is an effective treatment strategy in moderately ill patients hospitalized with Covid-19.
