Key inclusion & exclusion criteria
|
Inclusion criteria: 1. Male or female, at least 18 years of age 2. Diagnosis of persistent non-infectious anterior uveitis in at least one eye, based on the standardization of uveitis nomenclature for reporting clinical data workshop (SUN Working Group. AJO 2005;140:509-516). For the diagnosis of anterior uveitis (e.g. iritis, iridocyclitis, anterior cyclitis), the anterior chamber must be the primary site of inflammation. 2.1. Persistent anterior segment inflammation defined as lasting > 3 months prior to the time of the screening visit 2.2. Patients with secondary posterior segment inflammation (e.g., anterior vitreous cell, mild vitreous haze, peripheral vasculitis, optic nerve edema, or cystoid macular edema) are eligible if, in the opinion of the investigator, the anterior segment inflammation is the principal source of posterior segment inflammation 3. Anterior chamber cell score of at least +2 at both the screening (Days -14 to -4) and baseline (Day -4 to 0) visits in the study eye despite topical corticosteroids at least three times a day for at least two weeks prior to baseline 4. Best-corrected ETDRS visual acuity score at screening and baseline of = 10 letters (i.e. Snellen equivalent of approximately 20/640 or better) in the study eye 5. Media clarity other than vitreous haze, pupillary dilation, and patient cooperation sufficient for adequate visualization of the optic nerve in the study eye 6. Allowable treatments at screening, baseline and treatment (Day 0) visits: 6.1 Topical corticosteroids or NSAIDs if on stable doses of at least three times a day for at least 2 weeks prior to screening and remain stable through treatment (Day 0) 6.2 Systemic immunosuppression if doses are stable for at least 3 months prior to screening and remain stable through treatment (Day 0) 6.3 Systemic corticosteroids if daily doses are =20 mg/day oral prednisone (or equivalent) are stable for at least 1 month prior to screening and remain stable through treatment (Day 0) 6.4 Topical cycloplegia (e.g. homatropine, atropine) at the investigator’s discretion 7. Female patients of childbearing potential must have a negative urine pregnancy test at the treatment (Day 0) visit 8. Written informed consent has been obtained 9. Written Authorization for Use and Release of Health and Research Study Information (US sites only) has been obtained 10. Written Data Protection Consent (European sites only) has been obtained 11. Written documentation has been obtained in accordance with state and country privacy requirements, where applicable 12. Ability to understand the informed consent and willingness to follow study instructions and likely to complete all required visits and procedures
Are the trial subjects under 18? no Number of subjects for this age range: F.1.2 Adults (18-64 years) yes F.1.2.1 Number of subjects for this age range F.1.3 Elderly (>=65 years) yes F.1.3.1 Number of subjects for this age range
Exclusion criteria: General exclusion criteria: 1. Female patients who are pregnant, nursing, or planning a pregnancy, or who are of childbearing potential and not using a reliable means of contraception 2. Uncontrolled systemic disease 3. Participation in an investigational trial within 30 days of study entry 4. Use of warfarin/heparin/enoxaparin or similar anticoagulant agent = 2 weeks prior to the treatment visit 5. Known allergy or sensitivity to the study medications, any component of the delivery vehicle, any corticosteroid, or any diagnostic agents used during the study (e.g., fluorescein, dilation drops) 6. Anticipated need to initiate or change doses of current systemic immunosuppression or systemic corticosteroids during the first 6 weeks of the study 7. Any condition (including inability to read visual acuity charts or language barrier) that precludes patient’s ability to comply with study requirements including completion of the study 8. Patient has a condition or is in a situation that in the investigator's opinion may put the patient at significant risk, may confound the study results, or may interfere significantly with the patient's participation in the study Ocular exclusion criteria: 1. Previous enrollment in a DEX PS DDS clinical trial 2. IOP > 21 mm Hg at screening or baseline 3. History of clinically significant IOP elevation in response to corticosteroid treatment in either eye (defined as an increase of >10 mm Hg and an absolute IOP of =25 mm Hg without the use of anti-glaucoma medications) unless there is a functioning trabeculectomy or seton (with IOP <18 mm Hg at screening and baseline) and there is no significant visual field loss in the investigator’s opinion 4. History, diagnosis, or clinical findings of ocular hypertension or glaucoma (e.g. elevated IOP, optic nerve head change consistent with glaucoma, glaucomatous visual field loss) in the study eye unless there is a functioning trabeculectomy or seton (with IOP <18 mm Hg at screening and baseline) and there is no significant visual field loss in the investigator’s opinion. Patients with a history of episodic increases in IOP due to inflammation and not due to corticosteroids may be eligible if they meet all other IOP and glaucoma medication exclusions 5. Use of anti-glaucoma medications in the study eye within 4 weeks prior to the screening visit or any use between screening and treatment visits 6. History of central serous chorioretinopathy in either eye 7. Any active ocular infection (i.e. bacterial, viral, parasitic, or fungal) in either eye at screening, baseline or treatment visits 8. Presence of active or inactive toxoplasmosis in either eye 9. Contraindication to pupil dilation in either eye 10. Any other ocular disease in the study eye that can interfere with the diagnosis or the assessment of disease progression such as corneal edema, posterior synechiae, iris or angle neovascularization 11. Periocular corticosteroid injections to the study eye = 8 weeks prior to the treatment visit 12. History of any intravitreal drug injection to the study eye = 26 weeks prior to the treatment visit 13. History of any intravitreal corticosteroid injection to the study eye unless all of the following criteria are met: a. The only corticosteroid injected intravitreally was triamcinolone acetonide b. The most recent dose was >26 weeks prior to the treatment visit c. All doses were = 4 mg 14. Any previous use of RetisertTM (fluocinolone acetonide intravitreal implant) in the st

Primary Outcome(s)
|
Primary end point(s): The primary efficacy variable is the anterior chamber cell score measured by biomicroscopy and based on the cell count, as follows: 0 = 0 cells* +0.5 = 1 – 5 cells (trace)** +1 = 6 – 15 cells +2 = 16 – 25 cells +3 = 26 – 50 cells +4 = > 50 cells
Note hypopyon if present.
* Rare cells, defined as < 1 cell seen per field, should be graded as zero ** Record actual cell count on Case Report Form for +0.5 grade only
There is no primary safety endpoint for the study.
