Non-infectious retinal vasculitis (RV) is a severe and sight-threatening condition that may present alone or in association with other ocular inflammation, typically requiring immunosuppressive therapy to help bring it under control. This proof-of-concept study aimed to show whether subcutaneous Acthar Gel, a repository corticotropin injection (RCI), can be a safe and effective novel potential therapeutic agent for retinal vasculitis.
Patients with active retinal vasculitis were treated with 80 units of subcutaneous RCI twice weekly and followed with serial ultra-widefield fluorescein angiography. Patients currently or previously treated with systemic corticosteroid 6 weeks prior to enrollment were excluded. Subjects on non-steroidal immunosuppressive therapy were required to have a stable dose for 6 weeks prior to entering the study.
Eighteen patients (30 eyes) were followed over 24 weeks with 9 patients (14 eyes) able to complete the study without protocol deviation. Any improvement in RV was seen in 90.0% of 30 total eyes at a mean time of 2.9 weeks. Mean response level (RL) at the 2, 4, 8, 12, and 24-week visits in per-protocol eyes was 12.1%, 33.9%, 41.3%, 52.2%, and 74.1% respectively (p ≤ 0.0002). Improvement to 50% or more by week 12 was seen in 50.0% of these eyes, with 26.7% achieving complete resolution of RV in a mean time of 15.5 weeks. No significant adverse events were seen.
RCI may be an effective therapeutic agent in the treatment of non-infectious RV. RCI was felt to be well tolerated. This study also introduces a novel means by which to evaluate RV activity.

Fluorescein angiography of per protocol study eyes (A-F) demonstrating changes in retinal vasculitis and generalized inflammation from week 0 (baseline) to week 12 to week 24. Of note, varying levels of improvement were seen, from mild to moderate to complete resolution by week 24.
