What Is the Current Market Landscape for RLF (CETRZN)?
CETRZN, marketed as ALLERGY RLF, is a monoclonal antibody therapy targeting allergic conditions. It addresses asthma and allergic rhinitis by inhibiting the interleukin-4 receptor alpha (IL-4Rα), blocking IL-4 and IL-13 pathways. Its approved indications include moderate-to-severe atopic dermatitis, bronchial asthma, and chronic rhinosinusitis with nasal polyps.
The drug entered the market after FDA approval in 2019, following EMA approval in 2020. It competes chiefly with biologics like Dupixent (dupilumab), which covers similar indications in this segment.
