DESPITE AN ABSENCE OF SYMPTOMS, EoE IS DRIVEN IN PART BY UNDERLYING TYPE 2 INFLAMMATION BENEATH THE SURFACE
IL-4 and IL-13 are drivers of type 2 inflammation, resulting in histologic, endoscopic, and symptomatic manifestations of EoE

IL-4 AND IL-13: KEY DRIVERS OF TYPE 2 INFLAMMATION; IL-13 FUELS FIBROSIS AND MUSCLE HYPERTROPHY7,8

|
THIS LEADS TO ESOPHAGEAL DYSFUNCTION, ESOPHAGEAL RIGIDITY, PROGRESSIVE DYSPHAGIA AND FOOD IMPACTION, AND STRICTURE FORMATION8 |
EoE, eosinophilic esophagitis; TGF-ß, transforming growth factor-beta.
MOA
ONLY DUPIXENT DIRECTLY TARGETS TWO OF THE KEY SOURCES OF EoE: IL-4 AND IL-13 SIGNALINGa
Type 2 inflammation drives local and systemic impacts in patients with EoE
