Filter by:Phase 3, multi-center, randomized, masked, controlled study to evaluate the safety and efficacy of an injectable fluocinolone acetonide intravitreal (FAI) insert for the management of subjects with chronic non-infectious uveitis affecting the posterior segment of the eye. Patients will be randomized to receive either a sham injection or the FAI insert and will be observed for three years following treatment.
Treatment with ACTHAR Gel will result in a reduction of ocular inflammation in patients with active ocular sarcoidosis that requires systemic immunosuppressant therapy (hypothesis)
The objective of this study is to compare and evaluate the efficacy of subcutaneous (40mg) adalimumab biweekly injections to intravitreal adalimumab (1.5 mg/ 0.03 mL) administration, given at zero, 2 weeks then every four weeks, in subjects with active non-infectious intermediate-, posterior-, or pan-uveitis.
Background: Uveitis is a serious eye disease that can cause vision loss. Treatment sometimes causes serious side effects or does not work. Researchers want to learn more about uveitis and why some people develop it. Objective: To learn clinical and genetic factors that may make people develop uveitis and influence how they respond to treatment. Eligibility: People ages 8 and older who have uveitis, scleritis, inflammatory eye disease, or a disease related to eye inflammation INCLUSION CRITERIA FOR COVID-19 COHORT: Participants with COVID-19 will be eligible if they: 1. Have a diagnosis of COVID-19 confirmed by a nasaopharyngeal swab (or another confirmative test) within less than or equal to 3 days prior, with symptoms of any severity. 2. Are able to give verbal consent. 3. Are 16 years of age or older. EXCLUSION CRITERIA FOR COVID-19 COHORT: Participants with COVID-19 will not be eligible if they: 1. Use regular prescription eye drops on the day of sampling. 2. Current use of antiviral medications. Design: Participants will be screened with: Medical history Physical exam Eye exam Participation lasts up to 10 years. The clinic visit schedule varies depending on participants eye disease: Baseline visit with annual follow-ups Baseline visit, visits at months 3 and 6, and annual follow-ups Another schedule set by the researcher Depending on participants eye disease, tests during each visit could include: Fluorescein angiography or indocyanine green angiography: Dye is injected through a needle in the arm and flows through the blood vessels in the eye. A camera takes pictures of the eye. Electroretinography: Participants sit in the dark with their eyes patched. After 30 minutes, numbing drops and contact lenses are put in the eyes. Then, the retina is stimulated with flashing lights. Perimetry: Participants look into a bowl or lens and press a button when they see a light. Conjunctival or corneal biopsy, or skin biopsy: A small piece of tissue is removed. Anterior chamber tap: A needle enters the eye to remove fluid. Blood and urine tests Saliva, stool, hair, or tear samples Cotton swab of the inside of the cheek. During the study, participants may need immunosuppressive treatment, such as drugs or injections in or around the eyes depending on their disease.
The Macular Edema Ranibizumab v. Intravitreal anti-inflammatory Therapy (MERIT) Trial will compare the relative efficacy and safety of intravitreal methotrexate, intravitreal ranibizumab, and the intravitreal dexamethasone implant for the treatment of uveitic macular edema persisting or reoccurring after an intravitreal corticosteroid injection. MERIT is a parallel design (1:1:1), randomized comparative trial with an anniversary close-out after 6 months of follow-up. The primary outcome is percent change in central subfield thickness from the baseline OCT measurement to the 12 week visit.
Intravitreal injection of up to 2 mg of infliximab has proved to be safe in animal models (rabbits and primates). These studies have shown no evidence of intraocular inflammation or toxicity by clinical, electrophysiological, and histopathological examination for up to 90 days even with 3 repeated monthly injections. However, the study conducted by Rassi et al was the only one to report the development of severe intraocular inflammation in one eye out of 12 rabbit eyes at 90 days following 3 intravitreal injections (2mg monthly). Unfortunately, clinical studies conducted on patients, so far, have raised serious concern about its safety and adverse effects. These clinical studies have shown various and inconsistent results in terms of the safety and efficacy of intravitreal infliximab. These studies were conducted on patients with refractory as well as naïve cases of age related macular degenerations choroidal neovascularization (AMD CNV), diabetic macular edema (DME), central retinal vein occlusion (CRVO), angiomatous malformations, pseudophakic macular edema, and uveitis. The doses used ranged from 0.5mg to 2mg. The initial study by Theodossaidis et al in 2009 did not report any intraocular inflammation in 3 patients receiving 2 intravitreal injections of 1 and 2 mg for refractory AMD CNV with 7 months follow up period.(8) Later several clinical studies have reported severe intraocular inflammation following intravitreal injections of infliximab in non-uveitic patients.These collected data have initiated a call for cautious use of intravitreal infliximab. On the other hand, studies investigating intravitreal infliximab in uveitis patients have shown improvement in vision, reduction in macular thickness on optical coherence tomography (OCT), and reduction in inflammation. In this study, we have investigated the safety and efficacy of 3 consecutive intravitreal infliximab injections (1 mg/0.05 mL, 6 weeks apart) in carefully selected group of patients with refractory uveitis in Behcet's disease.
Objective: To determine the clinical variables that influence aqueous outflow facility (Co) and intraocular pressure (IOP) in uveitis. Uveitic glaucoma is potentially blinding and occurs in 17-46% of chronic uveitis patients. Uveitic activity causes fluctuating IOP due to decreased Co, increased uveoscleral outflow or decreased aqueous production. Specific Aim 1: To evaluate the risk factors for high IOP and low Co in uveitis Hypothesis: Decreased Co and increased IOP will occur with increasing anterior chamber (AC) flare, AC cells, degree of synechial angle closure, increased duration of disease, higher uveitis activity and increasing steroid use Specific Aim 2: To determine prospectively the effect of AC flare on Co and IOP in "quiescent" uveitis Hypothesis: AC flare even in the absence of AC cells will cause progressive decline in Co. Methods: In this proof of concept study, thirty consecutive patients with acute or chronic uveitis will be recruited from the uveitis clinic. Ten patients with "quiescent" uveitis (no AC cells) will be recruited for the prospective arm and followed every 2-3 months for 3 visits. Co will be measured using 2-minute pneumatonometer tonography. The effect of risk factors on IOP and Co in uveitis will be studied using generalized linear modelling techniques. These risk factors include AC flare (using the laser flare meter), AC cells, degree of angle closure (by gonioscopy), duration of disease, disease activity and corticosteroid use within the last year. In the prospective study, the patients will be divided into subgroups with low flare (< 20ph/ms) and high flare (≥ 20 ph/msec) and the change in Co and IOP will be analyzed. Impact: This will be the first study to systematically analyze the risk factors for decrease in Co and increase in IOP in uveitis and to prospectively evaluate the effect of AC flare on Co. Proof that AC flare can damage the trabecular meshwork will corroborate previous experimental evidence and change the paradigm of uveitis treatment. Knowledge of the risk factors that affect Co and IOP will aid in identifying patients that may need escalation of their uveitis or glaucoma treatment to prevent optic nerve damage.
Macular edema is the most common sight threatening complication of uveitis which can lead to permanent loss of central vision. Triamcinolone acetonide ( the study drug)injection for treatment of cystoid macular edema(CME) is well established. The purpose of this study is to compare the safety and efficacy of injecting the study drug inside the eye(intravitreal injection) and behind the eye(subtenon injection)
The study is designed to evaluate the safety and efficacy of suprachoroidally administered triamcinolone acetonide, CLS-TA, in subjects with macular edema associated with non-infectious 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.
