Randomized, Double-Blinded, Placebo-Controlled Trial of Lebrikizumab in Adult Asthmatics Who Were Uncontrolled Despite Inhaled Corticosteroid Therapy (NEJM, 1011) [MEDLINE]: FEV1 studied from baseline-week 12
Lebrizumab Improved FEV1: lebrikizumab resulted in a larger increase in FEV1 in patients with high pre-treatment periostin levels (8.2% increase in FEV1) vs patients with low with pre-treatment periostin levels (1.6% increase in FEV1) -> therefore, high levels of IL-13 activity predicted lebrikizumab efficacy
Lebrikizumab Decreased the Fraction of Exhaled Nitric Oxide (FeNO) Indirectly
Pharmacology
IgG4 humanized monoclonal antibody that binds to IL-13: inhibits IL-13 function
IL-13 induces bronchial epithelial cells to secrete periostin (a matricellular protein that may induce airway remodeling in asthma)
