Subconjunctival sirolimus in the treatment of autoimmune non-necrotizing anterior scleritis: results of a phase I/II clinical trial.

ABSTRACT: PURPOSE:To investigate the safety, tolerability and efficacy of subconjunctival sirolimus injections as a treatment for active, autoimmune, non-necrotizing anterior scleritis. DESIGN:Phase I/II, single-center, open-label, nonrandomized, prospective pilot study. METHODS:Five participants with active, autoimmune, non-necrotizing anterior scleritis with scleral inflammatory grade of ?1+ in at least 1 quadrant with a history of flares were enrolled. A baseline injection was given, with the primary outcome measure of at least a 2-step reduction or reduction to grade zero in the study eye by 8 weeks. Secondary outcomes included changes in visual acuity and intraocular pressure, ability to taper concomitant immunosuppressive regimen, and number of participants who experienced a disease flare requiring reinjection. Safety outcomes included the number and severity of systemic and ocular toxicities, and vision loss ?15 ETDRS letters. The study included 6 visits over 4 months with an extension phase to 1 year for participants who met the primary outcome. RESULTS:All participants (N = 5, 100%; 95% CI [0.60, 1.00]) met the primary outcome in the study eye by the week 8 visit. There was no significant change in mean visual acuity or intraocular pressure. Three out of 5 patients (60%) experienced flares requiring reinjection. No systemic toxicities were observed. Two participants (40%) experienced a localized sterile inflammatory reaction at the site of the injection, which resolved without complication. CONCLUSIONS:Subconjunctival sirolimus leads to a short-term reduction in scleral inflammation, though relapses requiring reinjection do occur. There were no serious adverse events, though a local sterile conjunctival inflammatory reaction was observed.

Project description:PurposeTo evaluate the safety and potential efficacy of gevokizumab, an anti-interleukin 1β (IL-1β) monoclonal antibody, in the treatment of active, noninfectious, non-necrotizing anterior scleritis.DesignPhase 1/2, open label, nonrandomized, prospective, single-arm pilot trial.MethodsEight patients with active, noninfectious, non-necrotizing anterior scleritis with a scleral inflammatory grade of +1 to +3 in at least 1 eye were enrolled. In 1 patient both eyes were enrolled, for a total of 9 eyes (4 eyes with +1, 1 eye with +2, and 4 eyes with +3). Patients received 1 subcutaneous injection of 60 mg gevokizumab at baseline and then every 4 weeks for 12 weeks. Complete physical and ocular examinations were performed at each visit. The primary outcome was at least a 2-step reduction or reduction to grade 0 in scleral inflammation on a 0 to +4 scale according to a standardized photographic scleritis grading system by 16 weeks in the study eye compared to baseline. Secondary outcomes included changes in visual acuity, intraocular pressure, and trends in scleral grading. Participants who met the primary outcome were eligible to continue in the study for up to 52 weeks and received additional gevokizumab injections every 4 weeks until week 36, followed by 2 safety visits at weeks 40 and 52.ResultsSeven eyes from 7 patients met the primary outcome within a median time of 2 weeks following the first gevokizumab injection. No definitive changes in visual acuity or intraocular pressure were identified. There were no serious adverse events related to the study drug. A total of 43 adverse effects were reported, with 93% described as mild, 95% as nonocular, and only 14% deemed possibly caused by the investigational treatment.ConclusionsThe results of this small study suggest that blockage of IL-1β using gevokizumab may be beneficial in treating active, noninfectious anterior scleritis and that gevokizumab is well tolerated. Larger randomized trials are warranted to assess the true efficacy of gevokizumab in the treatment of non-necrotizing anterior scleritis.
