A Prospective, Multi-Center, Randomized, Double-Masked, Positive-Controlled Phase 3 Clinical Trial Designed to Evaluate the Safety and Efficacy of Iontophoretic Dexamethasone Phosphate Ophthalmic Solution Compared to Prednisolone Acetate Ophthalmic Suspension (1%) in Patients With Non-Infectious Anterior Segment Uveitis


The purpose of this study is to evaluate the safety and efficacy of ocular iontophoresis
with dexamethasone phosphate ophthalmic solution EGP-437 using the EyeGate® II Drug Delivery
System (EGDS) compared to prednisolone acetate ophthalmic suspension (1%) in patients with
non-infectious anterior segment uveitis.


Anterior uveitis is a disorder of the eye associated with intraocular inflammation of the
anterior portion of the uvea, particularly the iris and/or ciliary body. It is distinct from
other iterations of uveitis such as posterior, diffuse and intermediate uveitis although it
is the most common form of uveitis and accounts for approximately 75% of cases.

In a Phase 1/2 study (EGP-437-001), the delivery of EGP-437 (40 mg/mL dexamethasone
phosphate solution) at four different iontophoresis dose levels was studied in 40 subjects
with non-infectious anterior segment uveitis. The study demonstrated that a single EGP-437
treatment: lowered anterior chamber cell (ACC) scores in the majority of patients without
requiring additional treatment; produced low short-term systemic exposure to dexamethasone
and dexamethasone phosphate; and produced the most beneficial effects in the 1.6 and 4.8
mA-min dose groups; and caused mainly minor AEs and no non-ocular systemic corticosteroid
mediated effects were observed.

The Phase 3 study is intended to confirm and extend the results from the Phase 2 study. The
study is designed to assess the safety and efficacy Ocular Iontophoresis with EGP-437 4.0
mA-min at 1.5 mA and accompanying placebo eyedrops in comparison to Ocular Iontophoresis
with sodium citrate buffer solution 4.0 mA-min at 1.5 mA and accompanying prednisolone
acetate (1%) eyedrops for the treatment of non-infectious anterior segment uveitis.

Inclusion Criteria:

- Male or female, age 12 to 85 years with a diagnosis of non-infectious anterior
segment uveitis defined as an anterior chamber cell count of ≥ 11 cells

- Receive, understand, and sign a copy of the written informed consent form

- Be able to return for all study visits and willing to comply with all study-related
instructions

Exclusion Criteria:

- Have uveitis of infectious etiology

- Have active intermediate or posterior uveitis

- Known positive HLA-B27 with a severe (4+) fibrinoid reaction

- Have previous anterior segment uveitis episode in the study eye ≤ 4 weeks prior to
baseline visit

- Have used topical corticosteroid treatment in the study eye ≤ 48 hours prior to
baseline visit

- Have used oral corticosteroid within the past 14 days prior to baseline

- Have received intravitreal or sub-Tenon corticosteroid treatment in the study eye
within the past 6 months prior to baseline visit

- Currently using prescribed nonsteroidal anti-inflammatory agents (i.e., use of
over-the-counter dosages is allowable) or prescribed immunosuppressive agents, unless
the dose has been stable for the last six weeks and no change in dosing is
anticipated for the duration of the study

- Have IOP ≥ 25 mmHg at baseline, a history of glaucoma, or require ocular
anti-hypertensive medications in the study eye

- Be known steroid intraocular pressure responders in either eye

- Have open wounds/skin disease on the forehead area where the iontophoresis return
electrode will be applied

- Have severe lesions of the eyelids or the ocular surface impeding the application of
the iontophoresis applicator

- Have known allergy to dexamethasone or dexamethasone phosphate or any medication to
be used in this study

- Have history or diagnosis of ocular herpes, corneal lesion of suspected herpetic
origin, or Behçet's disease

- Have monocular or BCVA worse than 20/80 in the fellow eye

- Have optic neuritis of any origin

- Have clinically suspected or confirmed central nervous system or ocular lymphoma

- Planning to undergo elective ocular surgery during the study

- Have active hyphema, pars planitis, choroiditis, clinically significant macular
edema, toxoplasmosis scar, or vitreous hemorrhage

- Have severe/serious ocular pathology or medical condition which may preclude study
completion

- Have pacemaker and/or any other electrical sensitive support system

- Be pregnant or lactating female, or female of childbearing age and using inadequate
birth control method

- Have participated in another investigational device or drug study within 30 days of
baseline visit

- Have significant Fuch's Corneal Dystrophy
