Filter by:This study was designed to confirm the efficacy and safety of ranibizumab (0.5 mg) as adjunctive therapy when added to laser photocoagulation and/or as monotherapy in Asian patients with visual impairment due to Diabetic Macular Edema (DME).
This Phase 1 study will evaluate the safety, tolerability and duration of effect of a helical intravitreal triamcinolone implant for the treatment of diabetic macular edema over a three-year period.
This study will assess the efficacy and safety of ranibizumab (intravitreal injections) versus laser treatment in patients with visual impairment due to diabetic macular edema.
The purpose of this study is to compare a single intravitreal injection of 4.0 mg of triamcinolone acetonide and 1.25 mg of bevacizumab for the treatment of diabetic macular edema.
Summary of Study Rationale Near-infrared light (NIR) via light-emitting diodes (LED) treatment promotes retinal healing and improve visual function following high intensity laser retinal injury by augmenting cellular energy metabolism, enhances mitochondrial function, increases cytochrome C oxidase activity, stimulates antioxidant protective pathways, and promotes cell survival. LED directly benefits injured neurons in the retina, the lateral geniculate nucleus, and the visual cortex, where perception occurs. From a public health perspective, a Light-Emitting Diode (LED) Array study is important to conduct because it has been approved as a non-significant risk (NSR) device for treatment of eye disorders, it has a low cost of treatment, and it may serve as an effective, non-invasive alternative or adjunctive treatment to laser photocoagulation, the current standard of care for DME. Study Objectives and Hypotheses 1. To determine the effects of short term (3 month) near-infrared light (NIR) therapy on anatomic and functional abnormalities of diabetic macular edema as assessed by visual acuity, optical coherence tomography, multifocal electroretinography (mERG) and fundus bimicroscopy. 2. To assess safety of short term near-infrared light therapy in eyes with diabetic macular edema.
To investigate the role of ranibizumab and angiographically-directed peripheral scatter laser therapy in patients with clinically-significant diabetic macular edema (CSME) and peripheral nonperfusion. We propose a novel treatment of CSME in a subgroup of patients defined by a combination of ultrawide-field angiography (UWFA) and optical coherence tomography (OCT). Within this classification scheme, patients with CSME are subdivided by the presence of: 1) focal macular leakage, 2) vitreomacular interface traction, and/or 3) peripheral nonperfusion. The successful treatment of diabetic macular edema would be dictated by pathophysiology-directed therapy based on this classification. The subgroup of interest for this clinical trial is characterized by diabetic macular edema, peripheral nonperfusion on UWFA, and the absence of macular traction on OCT. This group of patients has previously not been well recognized or characterized due to limitations in previous, standard angiographic evaluation of the retinal periphery. We postulate that this subcategory represents one with a high rate of failure of accepted therapies given persistence of the basic pathophysiologic mechanism for CSME, namely ischemia-induced production of Vascular Endothelial Growth Factor (VEGF) from the retinal periphery. This also represents a population of patients with likely recurrence of CSME despite treatment with anti-VEGF therapy alone for the same reason.
The study will evaluate the safety and efficacy of the intravitreal dexamethasone implant in the study eye of vitrectomized subjects with diabetic macular edema. Subjects will be followed for 26 weeks.
This is a Phase 2, doubled-masked, randomized study of the efficacy and safety of Intravitreal Aflibercept Injection (IAI;EYLEA®;BAY86-5321) in subjects with diabetic macular edema (DME). Approximately 200 subjects will be randomized in the US, Canada, Australia and EU.
Diabetics retinopathy remains the major threat to sight in the working age population in the developed world. Furthermore, it is increasing as a major cause of blindness in other parts of the world, especially developing countries. Diabetic macular edema (DME) is a manifestation of diabetic retinopathy that produces loss of central vision. The triamcinolone intravitreal injection (1-4mg) is indicated to treatment of diabetic macular edema and it is considered an important treatment since it improves the visual acuity of patients with resolution of edema. Nepafenac is a non-steroidal anti-inflammatory drug (NSAID), usually sold as a prescription eye drop (0.1% solution). Nepafenac is manufactured by Alcon as Nevanac. It is approved by FDA as well as ANVISA. Pre-clinical studies suggest this medication showed efficacy to treat ocular posterior segment inflammation. The purpose of this study is evaluate the efficacy of intravitreal triamcinolone associated with nepafenac eye drops as treatment of diabetic macular edema.
Macular edema is the main cause of vision loss in diabetic patients. Its treatment is mainly based on laser photocoagulation, but has limited results. Alternative treatment are under investigation, such as vitrectomy and intravitreal injections of triamcinolone .The aim of VITRILASE is to compare the efficacy of these two treatments to laser photocoagulation for diabetic macular edema.
