Dexamethasone Implant for Retinal Detachment in Uveal Melanoma

Phase 1
Conditions
Exudative Retinal Detachment and Uveal Melanoma
Interventions
Registration Number
NCT04082962
Lead Sponsor
Ivana K. Kim
Brief Summary

This is an investigator-initiated Phase I study of a single dose of an intravitreally-administered dexamethasone implant (Ozurdex™) in subjects with uveal melanomas (UM) and exudative retinal detachments (ERD: build-up of fluid under the retina that causes it to detach) being treated with proton beam radiation (PBI) or plaque radiotherapy. Although PBI is an effective treatment for UM, ERDs may persist after radiation, leading to vision loss. Effective treatments for ERD are currently lacking. We are conducting this study to evaluate whether Ozurdex™ can help resolve ERDs that occur in patients with UM. Ozurdex™ has been approved by the Food and Drug Administration (FDA) to treat certain ocular conditions such as macular edema, non-infectious uveitis, and diabetic macular edema but it is not approved for use in patients with UM and ERD. This study will determine the safety of the dexamethasone implant and provide preliminary evidence of efficacy in this population.

Primary Outcome Measures
NameTimeMethod
Incidence of Treatment-Emergent Adverse Events Related to the ImplantThroughout 12 month study period

The primary outcome of the study will be to evaluate the safety of the implant. All adverse effects not related to the melanoma or radiation treatment identified by ocular examination, diagnostic tests, and subject reporting will be tabulated. This includes significant vision loss, other sight-threatening events, and unforeseen systemic events.

Secondary Outcome Measures
NameTimeMethod
Exudative retinal detachment resolution6 and 12 months after implant insertion

Will be assessed using spectral domain optical coherence tomography, B-scan ultrasonography, and optos wide-angle color photography.

Visual Acuity6 and 12 months after implant insertion

Measured with ETDRS chart.

ComplicationsThroughout 12 month study period.

The development of iris neovascularization and neovascular glaucoma.
