Short Treatment with Omalizumab for Severe Asthma

Patients will be told to stop abruptly (no progressive decrease of the dose) their Omalizumab treatment and they will not be prescribed new OMA. In case of loss of control, pulmonologist can adapt asthma treatment, as in usual care. In that case, OMA can be prescribed for a second line

"Patients will be prescribed the same dosage of Omalizumab than they received before randomization, according to their weight and total circulating IgE levels.~In case of safety concerns or loss of control, pulmonologist can modify the patient treatment regimen of OMA or other co-medications, as in usual care."
