ZURICH, September 9, 2013 /PRNewswire/ --
Cytos Biotechnology Ltd (SIX:CYTN) today announced additional results of the phase 2a clinical trial with CYT003, a first-in-class immune modulator in clinical development as a potential new treatment for allergic asthma. A post-hoc analysis of data published in the March issue of The Journal of Allergy and Clinical Immunology  are presented today at the European Respiratory Society Annual Congress in Barcelona .
The post-hoc analysis looked at TH2 activation assessed by baseline blood eosinophil (bEos) count as predictive marker for a response to the treatment with CYT003 versus placebo. The patients from the Phase 2a study were stratified into the two subgroups based on the median bEos in the overall study population: a lower bEos group was defined with peripheral eosinophils at ≤0.1 cells/nL and a higher bEos group was defined with peripheral eosinophils at >0.1 cells/nL.
The results of the post-hoc analysis suggest that the efficacy of CYT003 measured by asthma control, symptoms and medication use, bronchodilation and inflammation markers, is particularly evident in patients with allergic asthma in the higher bEos group. Patients treated with placebo experienced deterioration on all outcome measures, whereas patients treated with CYT003 remained controlled despite ICS withdrawal. In contrast all patients with low bEos remained controlled in spite of steroid withdrawl. This observation suggests that patients in the lower bEos group were not dependent on ICS therapy to achieve adequate control of their asthma. Of particular note, the effect on asthma control and FEV1 in CYT003- compared to placebo-treated patients was more pronounced in the higher bEoS patient subgroup than the reported outcome for the full study. These findings add to the evidence supporting the anti-inflammatory effect of CYT003 and its potential clinical be
