Brief summary:
This open-label study will pilot the use of systemic sunitinib malate, a dual inhibitor of vascular endothelial growth factor (VEGF) and platelet derived growth factor (PDGF), in five participants with Von Hippel-Lindau (VHL) to investigate its potential efficacy as a treatment for retinal angiomas. Participants will have visual dysfunction with either visual acuity loss or visual field loss from retinal angiomas secondary to genetically confirmed VHL. This open-label study will pilot the use of systemic sunitinib malate in five participants to investigate its potential efficacy as a treatment for retinal angiomas associated with VHL. Participants will receive nine months of sunitinib malate therapy (six cycles total - one cycle consists of 50 mg oral dose once daily for four weeks followed by a two week rest period). The primary outcome will be a change in the best-corrected visual acuity of more than or equal to 15 letters from baseline to the Week 36 visit. The secondary ocular outcomes will focus on retinal thickness and leakage of the retinal angioma at the Week 36 visit. Optical coherence tomography will document changes in retinal thickening and fluorescein angiography will be used to determine leakage of the retinal angioma.
