Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

14 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

  • Diagnosis of active or inactive non-infectious uveitis (pan, anterior, intermediate and posterior)
  • ETDRS BCVA score of ≥ 5 letters read in the study eye

Exclusion Criteria:

  • Any active ocular disease or infection in the study eye other than uveitis
  • Intraocular pressure > 22 mmHg or uncontrolled glaucoma in the study eye; patients with IOP of 22 or less in the study eye not excluded with no more than 2 IOP-lowering medications.
  • Any uncontrolled systemic disease that, in the opinion of the Investigator, would preclude participation in the study
  • Any topical ocular corticosteroid in the 10 days prior to baseline; intraocular or periocular corticosteroid injections in the 2 months prior to baseline; an OZURDEX implant in the 6 months prior to baseline; RETISERT or ILUVIEN implant in the 3 years prior to baseline.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Adverse Events
Time Frame: Baseline to 24 weeks
Number of patients with treatment-emergent adverse events (TEAEs) and serious adverse events (SAEs). An adverse event (AE) is the development of an undesirable medical condition or the deterioration of a preexisting medical condition after or during exposure to a pharmaceutical product, whether or not considered causally related to the product. A TEAE is an AE occurring on or after the date of the first dose of study drug or worsening relative to the pre-treatment state. An SAE is an AE that fulfils one or more of the following: results in death; is immediately life-threatening; requires hospitalization nor prolongation of hospitalization; results in persistent or significant disability or incapacity; results in a congenital abnormality or birth defect; or is an important medical event that may jeopardize the subject or may require medical intervention to present one of the outcomes listed above.
Baseline to 24 weeks

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Mean Intraocular Pressure in the Study Eye
Time Frame: Baseline, 24 Weeks
Intraocular pressure is the fluid pressure inside the eye. Tonometry is the method eye care professionals use to determine this. IOP is an important aspect in the evaluation of patients at risk of glaucoma. Tonometers in this study were calibrated to measure pressure in millimeters of mercury.
Baseline, 24 Weeks
Number of Patients With a Grade of 0 in Anterior Chamber Cells in the Study Eye
Time Frame: Baseline, 24 Weeks
The anterior chamber is the aqueous humor-filled space inside the eye between the iris and the cornea's innermost surface, the endothelium. The grading of cellular reaction in the anterior chamber helps in the assessment of the severity of uveitis. In this study, anterior chamber cells were graded following the Standardization of Uveitis Nomenclature working group recommendations. The following scale was used to grade the cells in the field: 0 = <1, 0.5+ = 1-5, 1+ = 6-15, 2+ = 16-25, 3+ = 26-50, and 4+ = >50 cells. A lower grade represents less inflammation in the eye.
Baseline, 24 Weeks
Number of Patients With a Grade of 0 in Anterior Chamber Flare in the Study Eye
Time Frame: Baseline, 24 Weeks
The anterior chamber is the aqueous humor-filled space inside the eye between the iris and the cornea's innermost surface, the endothelium. The grading of intraocular inflammation or flare in the anterior chamber helps in the assessment of the severity of uveitis. In this study, anterior chamber flare was graded following the Standardization of Uveitis Nomenclature working group recommendations. The following scale was used to grade the flare: 0 = none, 1+ = faint, 2+ moderate (iris and lens details clear), 3+ = marked (iris and lens details hazy), 4+ = intense (fibrin or plastic aqueous). A lower grade represents less inflammation in the eye.
Baseline, 24 Weeks
Number of Patients With a Grade of 0 in Vitreous Haze in the Study Eye
Time Frame: Baseline, 24 Weeks
The vitreous body is that part of the eye that fills the space in the center of the eye. The primary purpose of the vitreous body is to keep the center of the eye clear so that light can get to the retina and vision can begin. Vitreous haze involves the obstruction of the back of the eye by vitreous cells and protein exudation. In this study, vitreous haze was graded following a standardized photographic scale ranging from 0 to 4. The following scale was used to grade the vitreous haze: 0 = no inflammation, +0.5 = trace inflammation, +1 = mild blurring of the retinal vessels and optic nerve, +1.5 = optic nerve head and posterior retina view obscuration greater than +1 but less than +2, +2 = moderate blurring of the optic nerve head, +3 = marked blurring of the optic nerve head, +4 = optic nerve head not visible. A lower grade represents less inflammation in the eye.
