NCT ID: NCT05105347 Not yet recruiting - Uveitis Clinical Trials

Efficacy and Safety of Adalimumab Plus Medium Dose Oral Glucocorticosteroid for Refractory Behçet's Uveitis

Start date: November 10, 2021
Phase: Phase 4
Study type: Interventional

This study is a multi-center randomized non-inferiority study that aims to observe the short-term (3 months) efficacy and safety of adalimumab plus medium-dose glucocorticosteroid (30mg/d prednisone or equivalent) with slow tapering for recurrent Behçet's uveitis (BU) attack compared with adalimumab plus high-dose glucocorticosteroid (60mg/d prednisone or equivalent) with slow tapering.

NCT ID: NCT05102994 Enrolling by invitation - Uveitis Clinical Trials

Mutation Detection for VRL

Start date: November 10, 2021
Phase:
Study type: Observational

Vitreoretinal lymphoma (VRL) is a rare but aggressive masquerade syndrome, which would be easily confused with uveitis. The diagnostic gold standard remains the pathologic examination of ocular specimen with invasiveness and low sensitivity. To improve the safety and accuracy of VRL diagnosis, alternative techniques using intraocular fluid (IOF) samples are emerging. In this study, we aimed to test the diagnostic value of mutation analysis for VRL

NCT ID: NCT05101928 Recruiting - Uveitis, Posterior Clinical Trials

Ozurdex Monotherapy Trial

OM
Start date: November 30, 2021
Phase: Phase 4
Study type: Interventional

This study will investigate the efficacy and safety of OZURDEX® (dexamethasone intravitreal implants; DEX, Allergan, Inc. Irvine, CA) as monotherapy for the treatment of non-infectious intermediate-, posterior- or panuveitis. This is a prospective randomized controlled clinical trial taking place at the University of Ottawa Eye Institute, Ottawa, Ontario, Canada, and other possible centers in Canada. Consecutive consenting subjects who meet inclusion/exclusion criteria will be selected to participate in this study. The subjects must have either non-infectious intermediate, posterior, or panuveitis. The subjects will be randomly chosen to be part of one of two groups; one group will receive DEX as monotherapy and the other group will receive oral prednisone. Approximately 84 eyes (42 per arm) will take part in study. The primary outcome will measure the proportion of eyes with a vitreous haze score of 0 six months post initial treatment. Secondary measures will include best corrected visual acuity (BCVA), central retinal thickness (CRT) measured by spectral-domain optical coherence tomography (SD-OCT), time to vitreous haze resolution and time to failure defined at number of months with DEX implant until an adjunct therapy is indicated. Baseline measurements will be recorded within 1 month prior to treatment in both groups, with follow up measurements collected at 0, 1, 2, 4, 6 and 12 months post-operatively.

NCT ID: NCT05015335 Recruiting - Uveitis, Anterior Clinical Trials

The Efficacy and Safety of Adalimumab in Non-infectious Anterior Pediatric Uveitis With Peripheral Vascular Leakage

Start date: August 19, 2021
Phase: Phase 4
Study type: Interventional

Children with anterior uveitis are prone to suffer from chronic recurrent course of intraocular inflammation and adverse effects of glucocorticosteroids (GCs) /immunomodulatory treatment (IMT) agents. The performance of adalimumab has been shown to be fairly favorable in treating refractory non-infectious uveitis. This study aims to assess the efficacy and safety of adalimumab for inflammatory flare prevention in non-infectious anterior pediatric uveitis with peripheral vascular leakage compared with methotrexate. Children weighed ≥ 30kg and aged between 4-16 years old with active chronic non-infectious anterior uveitis with peripheral retinal vascular leakage on ultra wildfield fluorescence fundus angiography (UWFFA) will be included. They will be treated with a predesigned inflammatory control regimen to reach inflammatory quiescence in 1 month. After that they will be treated with either MTX or adalimumab and regularly followed up for at least 6 months. The primary endpoint is treatment failure defined as any inflammatory fare with anterior chamber cell count grading increased from 0 to 1. Secondary endpoints are best corrected visual acuity (BCVA), inflammation parameters (keratic precipitates, vitreous haze grades), extent of vascular leakage, frequency of topical steroid eyedrops, systemic immunosuppressive drug load, and adverse events.

NCT ID: NCT05005637 Enrolling by invitation - Tuberculous Uveitis Clinical Trials

The Effectivity of Anti Tuberculosis Therapy in Idiopathic Uveitis With Positive IGRA

Start date: July 27, 2021
Phase: Phase 2
Study type: Interventional

The reported incidence of uveitis is 52 persons per year per 100,000 population, with a greater incidence estimated in developing countries, including Indonesia. Uveitis has challenges in diagnosis and therapy, due to the existence of an immunological privilege mechanism, so it is not easy to obtain diagnostic markers or provide appropriate therapy. In uveitis, a work-up examination looking for signs in the entire body or systemic disease is often conducted. Up until today, establishing the diagnosis of tuberculosis (TB)-associated uveitis is still a challenge. From histopathological studies, TB germs are difficult to find. Wreblowski et al. found that paucibacillary conditions also made TB bacteria difficult to find by PCR and tuberculin test results were also not completely reliable. The development of IGRA (Interferon-Gamma Release Assay) assays, such as QuantiFERON-Gold TB (QFT) has been investigated. Our previous study found that IGRA-positive uveitis patients with type 1 IFN gene expression score >5.61 were more likely to have active TB uveitis. In addition, serum C1q examination also showed an inverse correlation with this score. Regarding therapy, until now corticosteroids and cycloplegics are the mainstay treatment for uveitis. However, appropriate administration of anti-infective drugs is necessary in cases of infection. Inflammation in TB-associated uveitis is thought to be the result of the immune response that occurs as a result of paucibacillary TB infection. Examinations can be redundant and problematic. Determination of therapy is also a dilemma because it is difficult to determine the right patient candidate for administration of anti-tuberculosis therapy (ATT). The protocol of ATT administration itself has not been standardized so it often follows the extra pulmonary TB protocol and there has been no reliable clinical trial research on ATT administration in patients with suspected TB uveitis yet no TB microorganisms are found directly in the eyes or other organs. On this basis, the investigators planned a prospective randomized clinical trial study that involve idiopathic uveitis patients with positive IGRA test, to assess the effectivity of ATT compared to oral steroids. In addition, this study can also be used as a basis for validation of type 1 IFN scores and serum C1q as diagnostic/prognostic biomarkers in cases of TB-associated uveitis.

NCT ID: NCT04914884 Active, not recruiting - Clinical trials for Intraocular Inflammation

Intraocular Fluid Detection in Endophthalmitis

Start date: June 1, 2021
Phase:
Study type: Observational

Endophthalmitis is also called vitreous inflammation. Broadly speaking, it refers to all kinds of serious intraocular inflammation, such as vitreitis, anterior chamber empyema and eye pain caused by intraocular infection, intraocular foreign body, tumor necrosis, severe non infectious uveitis, lens cortex allergy, etc. Clinically, it generally refers to infectious endophthalmitis caused by bacteria, fungi or parasites. According to the different ways of infection, it can be divided into exogenous endophthalmitis and endogenous endophthalmitis. Exogenous endophthalmitis is more common. When inflammation involves sclera or extraocular orbital tissue, it is called "panophthalmia". Endophthalmitis is a kind of serious intraocular inflammation which can lead to the loss of visual function. Early diagnosis and treatment is the key. Studies have found that the changes of cytokines in aqueous humor are helpful for the diagnosis of endophthalmitis. Okhrvai et al. Also pointed out that the application of PCR can reduce the diagnosis time of endophthalmitis. This study mainly verified the use of molecular biology technology to detect the changes of VCAM, ICAM-1 and other cytokines, bacteria, viruses, fungi, Toxoplasma gondii IgG in patients' intraocular fluid, including aqueous humor and vitreous humor, so as to timely judge the etiology and progress of endophthalmitis, and provide reference for diagnosis and treatment.
