These benefits were seen regardless of the amount of respiratory support and were additional to the benefits of systemic corticosteroids. In hospitalised COVID-19 patients with hypoxia and systemic inflammation, tocilizumab improved survival and other clinical outcomes.

Among those not receiving invasive mechanical ventilation at baseline, patients allocated tocilizumab were less likely to reach the composite endpoint of invasive mechanical ventilation or death (35% vs 42% risk ratio 0♸4 95% CI 0♷7-0♹2 p<0♰001). Patients allocated to tocilizumab were more likely to be discharged from hospital within 28 days (57% vs 50% rate ratio 1♲2 1♱2-1♳3 p<0♰001). Consistent results were seen in all prespecified subgroups of patients, including those receiving systemic corticosteroids. Overall, 621 (31%) of the 2022 patients allocated tocilizumab and 729 (35%) of the 2094 patients allocated to usual care died within 28 days (rate ratio 0♸5 95% CI 0♷6-0♹4 p=0♰028).

The trial is registered with ISRCTN (50189673) and ( NCT04381936).īetween April 23, 2020, and Jan 24, 2021, 4116 adults of 21 550 patients enrolled into the RECOVERY trial were included in the assessment of tocilizumab, including 3385 (82%) patients receiving systemic corticosteroids.

The primary outcome was 28-day mortality, assessed in the intention-to-treat population. A second dose could be given 12-24 h later if the patient's condition had not improved. Those trial participants with hypoxia (oxygen saturation <92% on air or requiring oxygen therapy) and evidence of systemic inflammation (C-reactive protein ≥75 mg/L) were eligible for random assignment in a 1:1 ratio to usual standard of care alone versus usual standard of care plus tocilizumab at a dose of 400 mg-800 mg (depending on weight) given intravenously. This randomised, controlled, open-label, platform trial (Randomised Evaluation of COVID-19 Therapy ), is assessing several possible treatments in patients hospitalised with COVID-19 in the UK. In this study, we aimed to evaluate the effects of tocilizumab in adult patients admitted to hospital with COVID-19 with both hypoxia and systemic inflammation.
