Optiquel® as Corticosteroid-sparing Therapy for Chronic Noninfectious Uveitis
Study Details
Study Description
Brief Summary
Background:
Uveitis is a serious inflammatory condition in which the body's immune system attacks parts of the eye, often causing vision loss. Uveitis treatments involve various drugs that suppress the immune system, but these medicines sometimes do not work or may cause serious side effects. Researchers are interested in developing new treatments for uveitis that are more effective and have fewer side effects.
Optiquel® is an experimental medication being tested for its effectiveness against uveitis. It contains B27PD, a small protein fragment, which is similar to proteins in the parts of the eye being attacked by the immune system. Taking Optiquel® (B27PD) by mouth may induce oral tolerance, in which the immune system is taught to recognize and not attack normal parts of the human body.
Objectives:
To evaluate the safety and effectiveness of B27PD (Optiquel®) as a treatment for uveitis.
Eligibility:
Individuals at least 18 years of age who have had noninfectious uveitis in one or both eyes for at least 3 months, have vision of 20/200 or better in at least one eye, and are taking daily prednisone or an equivalent medication.
Design:
Participants will be screened with a physical examination, medical history, blood and urine tests, and an eye exam.
This study will last a maximum of 52 weeks. During the first 12 weeks of the study, participants will have a study visit every 2 weeks. For the remainder of the study, participants will have a study visit every 4 weeks.
Participants will have frequent blood and urine tests, and will also have eye examinations and special procedures (fluorescein angiography and indocyanine green angiography) to evaluate the effectiveness of the treatment.
Participants will be randomly assigned into one of three groups and will receive either one of two different doses of B27PD or a placebo. During the study, participants will also have their dose of prednisone or other steroid medication reduced.
Participants will take one capsule three times per week on Monday, Wednesday, and Friday, for a total of 24 weeks. Participants may take the capsule with water, but should not consume any other drinks or any kind of food until at least 30 minutes have passed to prevent stomach upset. The capsules should be stored in the refrigerator.

Detailed Description
Objective: The objective of this study is to evaluate the safety and efficacy of the peptide B27PD (Optiquel®) as a corticosteroid-sparing agent for chronic non-infectious uveitis in participants receiving oral corticosteroid therapy alone or combined with an immunosuppressive agent in a proof-of-concept clinical trial.
Study Population: Patients with non-infectious uveitis requiring at least 20 mg but no more than 40 mg of oral prednisone, or equipotent dose of alternative corticosteroid medication to maintain a quiescent eye, will be eligible.
Design: In this single center, Phase I/II, double-masked, randomized, placebo-controlled, parallel group treatment study, the safety and efficacy of the peptide B27PD will be investigated in 60 participants with non-infectious uveitis. Initially, 60 participants were to be enrolled; however, due to lack of efficacy, only 31 participants were enrolled. Eligible participants will be randomized to one of three treatment groups: 1 mg B27PD, 4 mg B27PD or placebo, to be taken three times per week for 24 weeks. All remaining participants will be followed through a common termination date. The common termination date will be established once the last enrolled participant reaches his/her Week 28 visit (four weeks following his/her last investigational treatment).The time to recurrence of uveitis in either eye occurring in the 52 weeks following the initial dosing will be evaluated in each treatment group. Recurrence will be defined as an increase in anterior chamber cells and/or vitreous haze of at least 2 steps [using the Standardization of Uveitis Nomenclature (SUN) grading system]. Ophthalmic examinations to assess uveitis will include visual acuity, intraocular pressure (IOP), slit lamp biomicroscopy, ophthalmoscopy, optical coherence tomography (OCT) and fluorescein angiography.
Outcome Measures: The primary outcome variable is the time to recurrence of uveitis activity in participants of each treatment group, during or after tapering of oral prednisone to a dose of 7.5 mg/day, or equipotent dose of alternative corticosteroid medication. Secondary efficacy outcome variables include the proportion of participants determined to be a Treatment Failure, defined as recurrence (or flare) of uveitis (at least a 2-step increase using the SUN grading system) or a drop in visual acuity of ≥ 15 Early Treatment Diabetic Retinopathy Study (ETDRS) letters at 24 and 52 weeks. Other secondary efficacy outcomes include the reduction in exposure to corticosteroid as measured by the area under the dose-time curve, and changes in best-corrected visual acuity (BCVA), fluorescein angiography, fundus autofluorescence and high-speed indocyanine green angiography (HS-ICG). Ocular safety measurements include intraocular pressure (IOP) and optical coherence tomography (OCT) for confirmation of suspected macular edema. Systemic safety variables include adverse events, clinical blood chemistry and hematology, urinalysis, vital signs, weight and medical evaluation at baseline and at the end of the study.

Outcome Measures
Primary Outcome Measures
- The Primary Outcome is the Time to Recurrence of Uveitis in Participants of Each Treatment Group, During or After Tapering of Oral Prednisone to a Dose of 7.5 mg/Day, or Equipotent Dose of Alternative Corticosteroid Medication. [Time from randomization to recurrence, loss to follow-up, or end of study, up to 52 weeks]
Recurrence (or flare) is defined as an anterior chamber cells and/or vitreous haze grading of ≥ 2+ using the Standardization of Uveitis Nomenclature (SUN) grading system. The time to this event is defined as the time from randomization to recurrence, loss to follow-up or end of study, whichever comes first. Participants that do not present with disease recurrence will be censored at the time of the last disease evaluation.
Secondary Outcome Measures
- Proportion of Participants Determined to be a Treatment Failure, Defined as Recurrent (or Flare) of Uveitis or a Drop in Visual Acuity of ≥ 15 Early Treatment Diabetic Retinopathy Study (ETDRS) Letters [Week 24]
Recurrent (or flare) of uveitis is defined as at least a 2-step increase in anterior chamber cells and/or vitreous haze using the Standardization of Uveitis Nomenclature (SUN) grading system
- Proportion of Participants Determined to be a Treatment Failure, Defined as Recurrent (or Flare) of Uveitis or a Drop in Visual Acuity of ≥ 15 Early Treatment Diabetic Retinopathy Study (ETDRS) Letters [Week 52]
Recurrent (or flare) of uveitis is defined as at least a 2-step increase in anterior chamber cells and/or vitreous haze using the Standardization of Uveitis Nomenclature (SUN) grading system
- Mean Change in Best-Corrected Visual Acuity (BCVA) in Right Eye (OD) at Week 24 Compared to Baseline [Baseline and Week 24]
Visual acuity was measured using the Early Treatment Diabetic Retinopathy Study (ETDRS) protocol. Acuity is measured as letters read on an ETDRS eye chart and the letters read equate to Snellen measurements. For example, if a participant reads between 84 and 88 letters, the equivalent Snellen measurement is 20/20.
- Mean Change in Best-Corrected Visual Acuity (BCVA) in Left Eye (OS) at Week 24 Compared to Baseline [Baseline and Week 24]
Visual acuity was measured using the Early Treatment Diabetic Retinopathy Study (ETDRS) protocol. Acuity is measured as letters read on an ETDRS eye chart and the letters read equate to Snellen measurements. For example, if a participant reads between 84 and 88 letters, the equivalent Snellen measurement is 20/20.
- Number of Participants Presenting No Change in Retinal Vessel Leakage Observed by Fluorescein Angiography (FA) at Week 24 Compared to Baseline [Week 24]
- Number of Participants Presenting No Change in Autofluorescence Patterns as Observed on Fundus Autofluorescence (FAF) at Week 24 Compared to Baseline [Week 24]
- Reduction in Exposure to Corticosteroid as Measured by the Area Under the Dose-time Curve. [Week 24]
This outcome was not analyzed as no data was collected at Week 24.
- Changes in High-speed Indocyanine Green Angiography (HS-ICG) [Week 24]
