Primary objective: safety and tolerability
Secondary objectives: additional indicators of long term safety and indicators of clinical activity
Exploratory objectives: to characterize EYS606 biodistribution, immunogenicity and biomarkers
|Condition or disease||Intervention/treatment||Phase|
|Non-infectious Uveitis||Biological: pEYS606||Phase 1 Phase 2|
The maximum study duration per patient is 51 Weeks (including an up to 3 week screening period + 48 weeks follow-up after treatment).
The study is conducted in 2 parts. Part 1 is a dose escalation phase which will investigate three pEYS606 doses levels (lower, intermediate and higher dose) over 3 cohorts. Part 1 of the study has been completed. Part 2, the extension phase, which is now ongoing will confirm to safety of the maximum tolerated higher dose from Part 1 and allow a preliminary assessment of efficacy.
|Study Type :||Interventional (Clinical Trial)|
|Actual Enrollment :||15 participants|

Cohort 1 (pEYS606 lower dose); Cohort 2 (pEYS606 intermediate dose); Cohort 3 (pEYS606 higher dose); Extension Cohort (pEYS606 maximum tolerated dose)
pEYS606 is a DNA plasmid solution administered by electrotransfection into the ciliary muscle

|Ages Eligible for Study:||18 Years and older (Adult, Older Adult)|
|Sexes Eligible for Study:||All|
|Accepts Healthy Volunteers:||No|
- Patient must be 18 years of age or older
- Both female patients of childbearing potential and male patients able to father a child must agree to practice at least one effective method of birth control for six months following administration of study medication. Acceptable methods of birth control for this study include hormonal contraception (birth control pills, injected hormones, dermal patch or vaginal ring), intrauterine device, barrier methods (diaphragm, condom) with spermicide or surgical sterilization (hysterectomy, tubal ligation or vasectomy). Patients with a hysterectomy or vasectomy (or have a partner with a hysterectomy or vasectomy) are exempt from using these methods of birth control.
- Female patients of childbearing potential must not be pregnant or breast-feeding and must have a negative urine pregnancy test at baseline and throughout the study.
- Voluntary written informed consent before performance of any study related procedure not part of normal medical care, with the understanding that consent may be withdrawn by the subject at any time without prejudice to future medical care.
- Patient has only one eligible eye with the following criteria:
- non-infectious intermediate, posterior, or panuveitis,
- media clarity, pupillary dilation, and individual cooperation sufficient for adequate fundus imaging,
- macular atrophy, AND/OR degenerative macular edema, AND/OR advanced optic neuropathy, AND/OR macular scar,
- Patients must maintain regiment of local and/or systemic corticosteroids between screening and baseline (if applicable).
Visual Criteria - Part 1 (enrolment is Part 1 is completed)
- BCVA of 0.1 (ETDRS of 35) or worse at screening in the treated eye, and BCVA of 0.32 or higher in the fellow eye.
Key Inclusion Criteria - Part 2 (enrolment in Part 2 is ongoing)
- BCVA of ≤ 0.63 or 20/32 Snellen but ≥ 0.025 or 20/800 Snellen (equivalent to ≥ 5 and ≤ 77 ETDRS letters) in the treated eye
- Patient must have a diagnosis of non-infectious uveitis of any anatomic subtype
- Patient must have a history of chronic or recurrent uveitis requiring or having required treatment with corticosteroids (systemic, periocular or intraocular) and/or systemic immunosuppressive medication(s) in the 12 months prior to the screening visit
- At the screening and baseline visits patient must have active uveitis as evidenced by at least one or more of the following in the study eye:
oActive retinal vasculitis (retinal vascular leakage) oVitreous haze grade ≥ 2+ oAnterior chamber cell grade ≥ 2+ oMacular edema
- Patient receiving concomitant topical and/or systemic corticosteroids or allowed systemic immunosuppressive medications must have maintained the same treatment regimen (dosage/frequency) for at least 2 weeks prior to the baseline (V1) visit, (if applicable).
- Willingness to receive local therapy to treat ocular inflammation in the fellow eye during the course of the study (if needed).
- Patient has or is suspected to have infectious uveitis or a uveitis masquerade syndrome.
- Patient suspected to have tuberculosis, has had a positive test for tuberculosis in the past or has a positive γ-interferon tuberculosis test at the screening visit.
- For a patient with a primary diagnosis of idiopathic intermediate uveitis exclusion of any signs of multiple sclerosis must be demonstrated by an MRI examination of the brain and orbits with gadolinium prior to the baseline visit.
- Patient with macular edema as the only evidence of uveitis (e.g. absence of any vitreous haze or vasculitis) for which a non-uveitic cause of macular edema such as cataract extraction, age-related macular degeneration, diabetic retinopathy or retinal vein occlusion cannot be excluded.
- Patient with media opacity in the study eye that precludes visualization of the fundus or that is likely to require cataract surgery during the course of the trial.
- Patient with history of glaucoma filtering surgery (e.g. trabeculectomy or aqueous shunt implant) or who underwent eye surgery within 3 months in the treated eye.
- Patient who has uncontrolled intraocular pressure of ≥ 25 mmHg in the study eye at the screening and baseline visits.
- Patient with intraocular hypotension (<6 mmHg) that in the opinion of the Investigator would interfere with the administration of EYS606 or the evaluation of its safety or efficacy.

- Patient has received Ozurdex® (dexamethasone implant) or other intraocular or periocular corticosteroids injections within 3 months prior to the baseline visit in the study eye
- Patient has received a fluocinolone implant (Retisert®, Illuvien®, YutiqTM) within 12 months prior to the baseline visit in the study eye.

- Patient with a history of allergic reaction or intolerance to any routinely used ophthalmic medicines (e.g. fluorescein dye, topical dilating agents or local anesthetics) that will be prescribed during the course of the study.
- Patient with active or uncontrolled underlying systemic autoimmune or inflammatory disease requiring or likely to require an increase in systemic immunosuppressive medications or treatment with a biologic agent during the course of the study.
- Patient has received treatment with an alkylating agent (cyclophosphamide or chlorambucil) for the management of uveitis or an associated underlying disease.
- Patient has received treatment with a systemic biologic therapy (e.g. anti-TNFα, anti-IL-1, anti-IL-6, anti-IL-17, interferon) within 1 month prior to the baseline visit.
- Patient has received treatment with Rituximab within 6 months of the baseline visit.
- Patient with a history of or current evidence of any unstable medical condition (such as heart disease due to a cardiac conduction abnormality requiring a pacemaker, neurologic or psychiatric disorders requiring electroconvulsive therapy, acute or chronic liver diseases, malignancy, severe systemic allergy, etc.) that in the opinion of the Investigator, would expose the subject to an undue risk of a significant adverse event or interfere with the administration of EYS606 or the evaluation of its safety or efficacy during the course of the trial.
