A second rheumatoid arthritis drug has failed to improve the condition of patients with severe Covid-19 associated pneumonia. Actemra (tocilizumab) did not meet its primary endpoint in a Phase 3 trial of hospitalised Covid-19 patients, Roche announced on 29 July. This follows news earlier in the month that a trial of Kevzara (sarilumab), also for hospitalised Covid-19 patients, was stopped early on lack of efficacy and adverse events.
