Clinically meaningful FEV1 response with reslizumab achieved early and sustained over 52 weeks
Background: Reslizumab (RES) is a humanized anti-interleukin-5 monoclonal antibody that significantly reduces the risk of asthma exacerbations and improves asthma control, lung function, and quality of life in patients with uncontrolled eosinophilic asthma. The mean difference in FEV 1 in RES treated patients vs placebo (PBO) at 16 and 52 weeks has been shown to be statistically and clinically significant (Castro et al., Lancet Respir Med. 2015; 3:355–366), but individual responders have not been assessed. Aims/Objectives: To assess the proportion of RES-treated patients who achieved a ≥0.1L increase in FEV 1 from baseline and the duration of treatment before response occurs. Methods: This …
Reslizumab (RES) in patients (pts) with inadequately controlled asthma and elevated blood eosinophils (EOS): Analysis of two phase 3, placebo-controlled trials
Background: RES reduced exacerbation frequency and improved lung function and asthma control in pts with inadequately controlled asthma and elevated blood EOS in two placebo (PBO)-controlled, phase 3 studies (Castro et al. Lancet Resp Med 2015). Aims/objectives: To determine the efficacy of RES in the subset of pts in these studies meeting the definition of ATS/ERS-defined inadequately controlled asthma. Methods: This was a post-hoc analysis of pooled data from two replicate, 52-week, PBO-controlled studies of RES (3mg/kg IV Q4W) in pts with inadequately controlled asthma and blood EOS ≥400/µL who were using medium-to-high dose inhaled corticosteroids; primary results have been reported.

Le comprimé d’immunothérapie sublinguale acariens SQ est efficace dans le traitement de l’asthme allergique ; résultats de l’essai de phase III MITRA
Introduction Les allergenes d’acariens domestiques sont associes a une pathologie respiratoire persistante. La rhinite allergique et l’asthme allergique (AA) coexistent frequemment. L’immunotherapie a le potentiel de modifier la cause de la maladie sous-jacente. Nous rapportons ici l’efficacite du comprime acarien d’immunotherapie sublinguale (ITSL) SQ-HDM (ALK, Danemark) sur le controle de l’asthme allergique aux acariens (AAA). Methodes L’essai europeen randomise en double aveugle controle par placebo MITRA (EudraCT 2010-018621-19) a inclus 834 sujets de 13 pays, ayant a l’inclusion un asthme allergique depuis plus d’un an, des tests de sensibilisation aux acariens positifs et un asthme m…
Against all odds: anti-IgE for intrinsic asthma?
For many years, pathogenetic concepts and the results of clinical trials supported the view that anti-IgE treatment is specifically effective in allergic asthma. However, there is now growing clinical and mechanistic evidence suggesting that treatment with the anti-IgE antibody omalizumab can be effective in patients with intrinsic asthma. Therefore, large and well-controlled clinical trials with anti-IgE are urgently warranted in patients with intrinsic asthma. In addition, there is a need to find new biomarkers which can identify patients with asthma who respond to anti-IgE treatment.
