Study Summary

This is a 2-part randomized, double-blind, placebo-controlled study followed by an open-label extension (OLE) of APT-1011 in adults with EoE. Part A will evaluate the efficacy and safety of APT-1011 3 mg administered hora somni (HS; at bedtime) for the induction of response to treatment (histologic and symptomatic) over 12 weeks. Part B will evaluate histological relapse-free status in patients re-randomized to continue APT-1011 or placebo (active treatment withdrawal) until Week 52. Part C, the OLE, will continue until regulatory approval of APT-1011 or Sponsor termination of the study.

Primary Outcome

To compare the Week 12 histologic responder rates (≤ 6 peak eosinophils \[eos\]/high power field \[HPF\]) for APT-1011 3 mg HS with that for placebo. HPF will be defined as a standard area of 235 square microns in a microscope with 40x lens (0.3 mm\^2) and 22 mm ocular
