What this phase means
Phase 4: the treatment is already approved. This study asks new questions — longer-term effects, other diseases, or how it compares in everyday care.
Phase labels are FDA/ICH categories applied to the registry Phase field. They are not a finding that this study succeeded.
What the registry says happens

Single center, randomly assigned, dummy treatment (placebo)- controlled study to assess change in mucociliary clearance of moderate to severe asthma patients after treatment with dupilumab or dummy treatment (placebo).
