Mycotic Ulcer Treatment Trial II

2014-07-23 21:12:26 | BioPortfolio

Summary

The purpose of this study is to determine if the addition of oral voriconazole to topical treatment regimens results in lower rates of perforation in severe fungal corneal ulcers.

Description

Fungal corneal ulcers tend to have very poor outcomes with commonly used treatments. There has only been a single randomized trial of anti-fungal therapy for mycotic keratitis, and no new ocular anti-fungal medications have been approved by the FDA since the 1960s. The triazole voriconazole has recently become the treatment of choice for systemic fungal infections such as pulmonary aspergillosis. The use of topical ophthalmic preparations of voriconazole has been described in numerous case reports, however there has been no systematic attempt to determine whether it is more or less clinically effective than natamycin. Additionally, there have been many case reports of the use of oral voriconazole in the treatment of fungal corneal ulcers, however there has been no systematic attempt to determine if it improves outcomes in severe ulcers.

This study is a randomized, double-masked, placebo-controlled trial to determine if the use of oral voriconazole in severe ulcers reduces the rate of perforations. 240 fungal corneal ulcers with baseline visual acuity worse than 6/120 presenting to the Aravind Eye Hospitals and the UCSF Proctor Foundation will be randomized to receive topical voriconazole and oral voriconazole, or topical voriconazole and oral placebo. The primary outcome is the rate of perforation over the three month follow-up period.

Medical and Biotech [MESH] Definitions

New blood vessels originating from the corneal veins and extending from the limbus into the adjacent CORNEAL STROMA. Neovascularization in the superficial and/or deep corneal stroma is a sequel to numerous inflammatory diseases of the ocular anterior segment, such as TRACHOMA, viral interstitial KERATITIS, microbial KERATOCONJUNCTIVITIS, and the immune response elicited by CORNEAL TRANSPLANTATION.

Loss of epithelial tissue from the surface of the cornea due to progressive erosion and necrosis of the tissue; usually caused by bacterial, fungal, or viral infection.

The measurement of curvature and shape of the anterior surface of the cornea using techniques such as keratometry, keratoscopy, photokeratoscopy, profile photography, computer-assisted image processing and videokeratography. This measurement is often applied in the fitting of contact lenses and in diagnosing corneal diseases or corneal changes including keratoconus, which occur after keratotomy and keratoplasty.
