Uveitis Clinical Trial - Posterior Subtenon Versus Intravitreal Injection

Status Withdrawn

Clinical Trial Summary

Macular edema is the most common sight threatening complication of uveitis which can lead to permanent loss of central vision. Triamcinolone acetonide ( the study drug)injection for treatment of cystoid macular edema(CME) is well established. The purpose of this study is to compare the safety and efficacy of injecting the study drug inside the eye(intravitreal injection) and behind the eye(subtenon injection)

Clinical Trial Description

The study is randomized interventional non inferiority study that will enroll 30 adults aged 18 or older with the diagnosis of cystoid macular edema secondary to non-infectious uveitis. Potential subjects will be recruited from the retina and uveitis clinics at the Casey Eye Institute, Oregon health and science University(OHSU). Potential recruits will be asked to sign and date the informed consent and a copy will be given to subject prior to any study procedure. Subjects will have a screening visit before the injection procedure so that the study doctor can decide if they meet the criteria to be in the study. This study requires 6 visits to the clinic and will take 6 months to complete. During the screening visit, medical/ surgical/ ocular history and will be collected from the subject and medical records. Laboratory tests will be performed to rule out infectious uveitis if the subject has not already had infectious types of uveitis ruled out since the time of diagnosis of uveitis. Urine collection for pregnancy test for females of childbearing potential will be done. Examination of subjects will include measurement of visual acuity, examination of the front and back part of the eye, measurement of the eye pressure . A scan of the retina will be obtained by spectral domain optical coherence tomography (SD-OCT). During the injection visit, history, examination, and pregnancy tests will be repeated in addition to receiving the injection. Subjects will be randomized to either injecting the study drug by intravitreal or subtenon routes. Examination after injection will be performed to rule out immediate complications. Then subjects will have 4 follow-up visits (2 weeks, 1 month, 3 months and 6 months). During each visit, subjects will be asked about adverse events, concomitant medications, how their eyes feel in addition to obtaining a clinical examination and OCT. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
