Brief Summary:

Eosinophilic esophagitis (EoE) is an inflammatory disease of the esophagus, characterized by eosinophilic infiltration and gastrointestinal symptoms. Swallowed, topically acting corticosteroids, such as fluticasone, appear to be effective in resolving acute clinical and pathological features of EoE.

APT-1011 is an orally disintegrating tablet (ODT) formulation of fluticasone propionate. This study is designed to compare the efficacy and safety of APT-1011 with placebo in adults with EoE for an initial 12-week treatment period, followed by an additional 40-week maintenance treatment phase. Histologic response, pharmacokinetics, and dysphagia will be assessed.

Condition or disease Intervention/treatment Phase
Eosinophilic Esophagitis Drug: APT-1011 Drug: Placebo Phase 2

Detailed Description:

FLUTE is a phase 2b randomized, double-blind, placebo-controlled dose-ranging clinical trial of APT-1011 versus placebo in 100 adult subjects (≥18 years of age) diagnosed with EoE. Efficacy (including histologic, endoscopic, and symptomatic response), safety, and PK of APT-1011 will be examined. Participants will be given an electronic diary to record symptoms and medication intake daily.

FLUTE will be conducted in several parts (Screening [4 weeks], followed by a 4-week Baseline Symptom Assessment, and 2 treatment parts [Part 1: 14-week Induction and Part 2: 38-week Maintenance]), with a follow-up visit to occur 2 weeks after the final dose of study drug.

In Part 1 of the study, 100 subjects will be randomized 1:1:1:1:1 to receive placebo or one of 4 active doses of APT-1011. All subjects will receive one tablet 30 minutes after breakfast and one tablet at bedtime (HS). The dosing groups include: 1.5 mg HS APT-1011, 1.5 mg twice daily (BID) (total daily dose of 3 mg) APT-1011, 3 mg HS APT-1011, and 3 mg BID (total daily dose of 6 mg) APT-1011, and placebo BID.

In Part 2, all subjects classified as histologic responders at Week 12 will continue to be treated according to the dosing group to which they were randomized, and non-responders will receive single-blind 3 mg BID. All subjects who are histologic non-responders at Week 26 will stop treatment at Week 28 and enter the 2-week follow-up and exit the study. Histologic responders at Week 26 will continue on the same dose until end-of-study at Week 52.

Subjects will complete a follow-up visit 2 weeks after the final dose of study drug. All subjects must have a final EGD within 3 weeks prior to completing the Follow-up Visit unless the subject withdraws consent or has a contraindication to EGD.

Primary Outcome Measures :
  1. Histological response [ Time Frame: Week 12 ]
    Histology (eosinophils per high power field [HPF]): percentage of subjects with ≤6 PEAK eosinophils/HPF after assessing at least 5-6 biopsies from the proximal and distal esophagus (~3 each) where the HPF area is 235 square microns (40 magnification lens with a 22 mm ocular).

Secondary Outcome Measures :
  1. EoE sustained response [ Time Frame: Week 12, Week 26, and Week 52 ]
    Percentage of subjects who met the primary endpoint (histology) at Week 12 and maintained the primary endpoint at Week 26 and Week 52

  2. Change from baseline EREFs at Week 12, 26, and 52 [ Time Frame: Week 12, Week 26, and Week 52 ]
    Endoscopic changes will be assessed as per the EREFs evaluation based on the following endoscopic features: edema, rings, exudates, furrows, stricture, and several miscellaneous features (crepe paper esophagus, narrow caliber esophagus, and esophageal erosions).

  3. EoE histologic response [ Time Frame: Week 12, Week 26, and Week 52 ]
    Percentage of subjects with a peak eosinophils/HPF <1 and <15 at Week 12, 26 and 52.

  4. Change from baseline Global EoE Symptom Score [ Time Frame: Week 52 ]
    Compared score prior to randomization to scores for 7-day recall at Week 4, 8, 12, 14, 18, 22, 26, 28, 36, 44, and 52 visits

  5. Dysphagia [ Time Frame: Week 12, Week 26 and Week 52 ]
    Change in the number of dysphagia episodes at baseline (14-day period prior to randomization) compared with the 14-day period prior to the time point of interest

Other Outcome Measures:

    Number of subjects discontinuing due to HPA axis suppression

  2. Candidiasis [ Time Frame: baseline to Week 52 ]
