The arthritis drug tocilizumab has shown early promise in preventing extreme inflammation in gravely ill COVID-19 patients, according to a French clinical study.
The treatment, which suppresses the body's natural immune response, was found to reduce "significantly" the number of deaths or life support interventions compared with a control group of patients.
The study, carried out by the Paris university hospital trust (AP-HP), looked at 129 people hospitalised with moderate or severe viral pneumonia, which occurs in 5-10 percent of COVID-19 patients.
Half received two injections of tocilizumab as well as standard treatment with antibiotics, while the control group received only standard treatment.
