About
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.
Full description
Patients eligible for the study will be identified by the investigators and given a copy of the consent form to read. Patients interested in enrolling will be screened and if eligible will be enrolled in the study. The screening visit and the baseline visit may occur on the same day. Patients enrolling will be instructed in self-administering Acthar 80 IU twice a week. Patients will keep an injection log which will be inspected at each visit (4, 8, and 12 weeks). Ophthalmology data will be collected at each visit and recorded on the case report form by the ophthalmology technician working with the sub-investigator at the time of each visit. Patients will come to the Center for Clinical Studies each visit for blood draw, blood pressure recording, and recording of adverse events.
