About
This is a 24-week randomized, double-blind, placebo-controlled induction study of APT-1011 in adults (≥18 years old) with eosinophilic esophagitis (EoE) followed by a single-arm, open-label extension. This study will evaluate the efficacy and safety of APT-1011 3 mg administered HS (hora somni, at bedtime) for the induction of response to treatment (symptomatic and histologic) over 24 weeks. The open-label extension will continue to evaluate long-term safety in subjects who consent to continue on open-label treatment with APT-1011.
Full description
The efficacy and safety of APT-1011 3 mg administered at bedtime will be evaluated for the induction of response (histologic and symptomatic) after 24 weeks of treatment. After completing 24 weeks of double-blind study treatment, subjects may consent to participate in the open-label extension, otherwise they will complete study drug treatment and enter a 2-week off treatment safety follow-up.
The duration of the double-blind portion of the study, screening through follow-up visit for subjects completing study drug at Week 24, will be up to 32 weeks long, i.e., 6-week screening period (the includes a 4-week run-in phase) followed by 24 weeks induction phase and 2 weeks off-treatment follow-up. For subjects consenting to participate in the open-label extension, the duration of the study will be determined by the Sponsor.

Inclusion criteria
Adult male or female ≥18 years of age at the time of informed consent
Each subject must read, understand, and provide consent on the ICF for this study and be willing and able to adhere to study-related treatment regimens, procedures, and visit schedule
Diagnosis or presumptive diagnosis of EoE that is confirmed during the Screening period by histology that demonstrates ≥15 peak eos/HPF. In order to ensure that a diagnosis can be made, at least 6 biopsies should be taken in total from both proximal and distal esophageal mucosal areas (at least 3 each). Mid-esophageal biopsies are not required (optional). 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.
Have a subject-reported history of ≥6 episodes to a maximum of 30 episodes of dysphagia in a 14-consecutive-day period within 18 days prior to baseline
Completion of the evening eDiary on at least 11 out of the 14-consecutive-day observation period during the 4-week run-in period (Baseline Symptom Assessment).The minimum requirement of 11 days need not be consecutive.
