Stage 5?Depending on the TH2-cell activity.
Both allergic and eosinophilic have high TH2-cell activity, while neutrophilic asthma doesn't.
So omalizumab is for severe allergic asthma, and mepolizumab and reslizumab for severe eosinophilic asthma.
So non eosinophilic, allergic asthma: omalizumab would be fine.
Of course! That's only for severe (stage 5 therapy)
