Efficacy and safety of an anti-IL-13 mAb in patients with severe asthma: AÂ randomized trial

Although well tolerated, GSK679586 did not demonstrate clinically meaningful improvements in asthma control, pulmonary function, or exacerbations in patients with severe asthma. Further studies are needed to determine whether therapies targeting IL-13, the functionally related IL-4 cytokine, or both can provide clinical benefit in patients with severe refractory asthma or a subpopulation of these patients beyond that achievable with high-dose corticosteroids.
