Subconjunctival sirolimus for the treatment of chronic active anterior uveitis: results of a pilot trial.

ABSTRACT:

Purpose

To evaluate the safety and possible efficacy of subconjunctival sirolimus for the treatment of chronic active anterior uveitis.

Design

Prospective, nonrandomized, open-label clinical trial.

Methods

This single-center pilot trial enrolled 5 patients with chronic active anterior uveitis. The study drug was administered as a single subconjunctival injection of 30 ?L (1320 ?g) sirolimus in the study eye at the baseline visit. Study visits were performed at baseline, at 2 weeks, at 4 weeks, and monthly until 4 months, and included a complete ophthalmic examination, review of systems, adverse event assessment at each visit, physical examination, and ancillary ophthalmic testing at some visits. The primary outcome measure was a 2-step reduction in the anterior chamber inflammation within 4 weeks of injection of the study drug.

Results

There were 3 female and 2 male patients; 4 patients had idiopathic anterior uveitis and 1 had psoriatic arthritis-associated anterior uveitis. Three of the 5 patients met the primary outcome criteria by showing at least a 2-step decrease in inflammation within 4 weeks; 2 patients showed a 1-step decrease in inflammation within the same time frame. No recurrence was encountered during a 4-month follow-up. There were no serious adverse events.

Conclusions

Subconjunctival sirolimus appears to be well tolerated in this pilot trial and shows promise as a treatment for active inflammation in patients with chronic anterior uveitis. Larger studies are needed to assess its usefulness in uveitis.

Project description:PurposeTo estimate the incidence of medication-free remission of chronic anterior uveitis and identify predictors thereof.DesignRetrospective cohort study.ParticipantsPatients diagnosed with anterior uveitis of longer than 3 months' duration followed up at United States tertiary uveitis care facilities.MethodsEstimation of remission incidence and identification of associated predictors used survival analysis.Main outcome measuresIncidence of medication-free remission. For the primary analysis, remission was defined as inactive uveitis while off treatment at all visits spanning an interval of at least 90 days or-for patients who did not return for follow-up after 90 days-remaining inactive without receiving suppressive medications at all of the last visits. Association of factors potentially predictive of medication-free remission was also studied.ResultsTwo thousand seven hundred ninety-five eyes of 1634 patients with chronic anterior uveitis were followed up over 7936 eye-years (4676 person-years). The cumulative medication-free, person-year remission incidence within 5 years was 32.7% (95% confidence interval [CI], 30.4%-35.2%). Baseline clinical factors predictive of reduced remission incidence included longer duration of uveitis at presentation (for 2 to 5 years vs. less than 6 months: adjusted hazard ratio [aHR], 0.61; 95% CI, 0.44-0.83), bilateral uveitis (aHR, 0.75; 95% CI, 0.59-0.96), prior cataract surgery (aHR, 0.70; 95% CI 0.56-0.88), and glaucoma surgery (aHR, 0.63; 95% CI, 0.45-0.90). Two time-updated characteristics were also predictive of reduced remission incidence: keratic precipitates (aHR, 0.36; 95% CI, 0.21-0.60) and synechiae (aHR, 0.62; 95% CI, 0.41-0.93). Systemic diagnosis with juvenile idiopathic arthritis and spondyloarthropathy were also associated with reduced remission incidence. Older age at presentation was associated with higher incidence of remission (for age ≥40 years vs. <40 years: aHR, 1.29; 95% CI, 1.02-1.63).ConclusionsApproximately one third of patients with chronic anterior uveitis remit within 5 years. Longer duration of uveitis, younger age, bilateral uveitis, prior cataract surgery, glaucoma surgery, presence of keratic precipitates and synechiae, and systemic diagnoses of juvenile idiopathic arthritis and spondyloarthropathy predict reduced remission incidence; patients with these factors should be managed taking into account the higher probability of a longer disease course.

Project description:BackgroundJuvenile idiopathic arthritis (JIA) is the most common pediatric rheumatic disease and the most common systemic disorder associated with uveitis in childhood. Uveitis is more common in JIA patients who are antinuclear antibody (ANA)-positive, have an early-onset disease, and have oligoarticular arthritis. JIA-associated uveitis (JIA-uveitis) is typically anterior, chronic, bilateral, nongranulomatous, and asymptomatic. Visual outcomes in JIA-uveitis have improved with current screening and treatment options; however, many patients fail to respond or do not achieve long-lasting remission. Baricitinib, an oral selective Janus kinase (JAK)1 and 2 inhibitor, may impact key cytokines implicated in the pathogenesis of JIA-uveitis or ANA-positive uveitis, representing a potential novel treatment option for disease management.MethodsThe multicenter, phase 3 trial will be conducted using an open-label Bayesian design. The study will enroll at least 20 and up to 40 patients aged 2 to <18 years with active JIA-uveitis or chronic ANA-positive uveitis without systemic features. At least 20 patients who have had an inadequate response or intolerance to methotrexate (MTX-IR), but not biologic disease-modifying antirheumatic drugs (bDMARDs), will be randomized (1:1) to open-label baricitinib or adalimumab. Approximately 20 additional patients who are MTX-IR or bDMARD inadequate responders will receive baricitinib treatment. Patients will be treated with once daily oral baricitinib at a fixed dose by age group (4 mg for patients aged ≥6 to <18 years and 2 mg for patients <6 years) or adalimumab (20 mg for patients weighing <30 kg and 40 mg for patients ≥30 kg) as a subcutaneous injection every 2 weeks. Treatment with stable background conventional synthetic DMARDs, low-dose corticosteroids, and/or nonsteroidal anti-inflammatory drugs is allowed. The primary endpoint is the proportion of patients with response at week 24. Patients may continue treatment for up to 5 years.DiscussionThis is the first pediatric clinical trial to assess the clinical effectiveness and safety of a JAK inhibitor in JIA-uveitis or chronic ANA-positive uveitis. A novel Bayesian design is used to assess the efficacy of baricitinib, including an adalimumab reference arm, in this small patient population with unmet medical need.Trial registrationEudraCT 2019-000119-10 .

Project description:ObjectiveTo report the 2-year incidence of raised intraocular pressure (IOP) and glaucomatous optic nerve damage in patients with uveitis randomized to either fluocinolone acetonide (FA) implants or systemic therapy. Secondarily, we sought to explore patient and eye characteristics associated with IOP elevation or nerve damage.DesignA randomized, partially masked trial in which patients were randomized to either FA implants or systemic therapy.ParticipantsPatients aged ? 13 years with noninfectious intermediate, posterior, or panuveitis active within the prior 60 days for which systemic corticosteroids were indicated were eligible.MethodsVisual fields were obtained at baseline and every 12 months using the Humphrey 24-2 Swedish interactive threshold algorithm (SITA) fast protocol. Stereoscopic optic nerve photos were taken at baseline and at 3-, 6-, 12-, and 24-month follow-up visits. Masked examiners measured IOP at every study visit.Main outcome measuresGlaucoma was diagnosed based on an increase in optic nerve cup-to-disc ratio with visual field worsening or increased cup-to-disc ratio alone, for cases where visual field change was not evaluable, because of missing data or severe visual field loss at baseline.ResultsMost patients were treated as assigned; among those evaluated for glaucoma, 97% and 10% of patients assigned to implant and systemic treatment, respectively, received implants. More patients (65%) assigned to implants experienced an IOP elevation of ? 10 mmHg versus 24% assigned to systemic treatment (P<0.001). Similarly, 69% of patients assigned to the implant required IOP-lowering therapy versus 26% in the systemic group (P<0.001). Glaucomatous optic nerve damage developed in 23% versus 6% (P<0.001) of implant and systemic patients, respectively. In addition to treatment assignment, black race, use of IOP-lowering medications, and uveitis activity at baseline were associated with incident glaucoma (P<0.05).ConclusionsImplant-assigned eyes had about a 4-fold risk of developing IOP elevation of ? 10 mmHg and incident glaucomatous optic neuropathy over the first 2 years compared with those assigned to systemic therapy. Central visual acuity was unaffected. Aggressive IOP monitoring with early treatment (often including early filtration surgery) is needed to avoid glaucoma when vision-threatening inflammation requires implant therapy.Financial disclosure(s)Proprietary or commercial disclosure may be found after the references.
