Open Label Study of Acthar SQ Gel Injection in Patients With Active Anterior Uveitis
Prospective Open Label Study of Acthar SQ Gel Injection in Patients With Active Anterior Uveitis Who Are Not Well Controlled With, or Intolerant of, Topical or Systemic Corticosteroids
Uveitis is an acute or chronic inflammatory condition of unknown etiology. Although uveitis often responds adequately to topical corticosteroids, there are many patients for which this treatment is either inadequate or not tolerated. A patient with inadequate response to treatment would manifest uveitis activity by slit lamp examination determination of anterior chamber cellularity. Lack of tolerance of therapy commonly manifests as ocular hypertension (greater than 21 mmHg measured by tonometry)complicating chronic topical corticosteroid administration, leading to glaucoma and permanent visual loss. Moreover, systemic corticosteroids may be required at a dose unsafe for chronic administration. In these situations, an immunosuppressive medication is often added as a "steroid-sparing" agent. If and when there is clinical response to the added immunosuppressive, the oral and/or topical corticosteroid dose can be reduced or eliminated to avoid toxicity.
There are several reasons for believing that Acthar might be beneficial in the treatment of uveitis patients. In addition to increasing adrenal production or cortisol, Acthar has another important mechanisms of action mediated by its binding of melanocortin receptors. Melanocortin down-regulates activity of B and T lymphocytes, monocytes and macrophages. In animal studies, melanocortin peptides down-regulate T helper cells, up-regulate T Regulatory cells, and decrease B lymphocyte production of B Lymphocyte Stimulator. In macrophages, there is down-regulation of IL-1, IL-2, INF gamma, TNF alpha, nitric oxide and adhesion molecules. In other cells, in addition to IL-10 upregulation (monocytes), there is down-regulation of VACM and ECAM (endothelial cells), prostaglandins (fibroblasts) and MCP-1 and RANTES (renal tubules).CNS mediation of systemic inflammation may also be down-regulated by melanocortin receptor binding by Acthar.
