Brief Summary:
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.
| Condition or disease | Intervention/treatment | Phase |
|---|---|---|
| Eosinophilic Esophagitis | Drug: APT-1011 Drug: Placebo oral tablet Procedure: Esophagogastroduodenoscopy | Phase 3 |
Expanded Access : An investigational treatment associated with this study is available outside the clinical trial. More info ...
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.

- Mean Number of Dysphagia-Free Days [ Time Frame: Week 24 ]To compare the mean number of dysphagia-free days from baseline to Week 24
- Percentage of Responders (Strictures and ≥Grade 2 rings) [ Time Frame: Week 24 ]To compare the percentage of responders, defined as no longer having strictures and/or ≥Grade 2 rings which were present at baseline, at Week 24
- Percentage of Responders (Strictures) [ Time Frame: Week 24 ]To compare the percentage of responders, defined as no longer having strictures which were present at baseline, at Week 24
- Percentage of Responders (≥Grade 2 rings) [ Time Frame: Week 24 ]To compare the percentage of responders, defined as no longer having ≥Grade 2 rings which were present at baseline, at Week 24
- Mean Change in EREFs [ Time Frame: Week 24 ]To compare endoscopic appearance evaluated by the mean change from baseline to Week 24 in Eosinophilic Esophagitis Endoscopic Reference Score (EREFs)
- Time to First Complete Symptom Response [ Time Frame: Week 24 ]Time to first complete symptom response (defined as zero dysphagia episodes in a 14-consecutive-day period)

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).
