Overall, 140 patients were randomised to tralokinumab 300 mg or placebo (n=70 each) administered subcutaneously every 2 weeks. The primary endpoint was percent change from baseline in average OCS dose at Week 40, while maintaining asthma control. Secondary endpoints included proportion of patients with a prescribed maintenance OCS dose of ≤5 mg, those with a ≥50% reduction in prescribed maintenance OCS dose and asthma exacerbation rate. Safety was also assessed.At Week 40, the percent reduction from baseline in the final daily average OCS dose was not significantly different between tralokinumab and placebo (37.62% versus 29.85%; p=0.271). There were no significant between-treatment differences for any secondary endpoint. Overall, reporting of adverse events (AEs) and serious AEs were similar for the tralokinumab and placebo groups. Although a greater proportion of tralokinumab-treated patients reported upper respiratory tract infections (35.7% versus 14.3%), there were no reported cases of pneumonia.Overall, tralokinumab did not demonstrate an OCS-sparing effect in patients with severe asthma.FootnotesThis manuscript has recently been accepted for publication in the European Respiratory Journal.
