Filter by:The purpose of this study is to evaluate anatomical and functional effect of combination therapy of Squalamine Lactate Ophthalmic Solution, 0.2% administered twice daily with monthly ranibizumab intravitreal injections in patients with choroidal neovascularization due to AMD.
The purpose of this prospective interventional study is to assess whether adjunctive verteporfin photodynamic therapy (PDT) is effective for the treatment of persistent disease activity in neovascular age-related macular degeneration (NV AMD), as compared to anti-VEGF therapy (aflibercept) alone. This study will enroll individuals with NV AMD who have persistent disease activity in spite of either loading dose (initial 3-5 anti-VEGF treatments) or maintenance (established course) anti-VEGF therapy to determine whether PDT can improve disease activity, facilitate sustained visual acuity gains, and decrease burden of frequent anti-VEGF treatments for affected patients. Risks of study are related to treatment with study drugs: intravenous verteporfin, intravitreal triamcinolone acetonide, and intravitreal aflibercept. All have been studied extensively in clinical trials and are established treatments used routinely in NV AMD. Adverse events will be monitored by the principal investigator and study team.
This clinical study is a phase 1 study which carried out to to evaluate the safety, pharmacokinetics and tolerability of multiple intravitreal injections of BCD-021(bevacizumab biosimilar candidate manufactured by CJSC BIOCAD, Russia) when used in patients with neovascular wet age-related macular degeneration.
Pathologic myopia is a major cause of legal blindness worldwide. In myopic macular degeneration (MMD), there is degeneration of the retinal pigment epithelial (RPE) layer, and associated photoreceptors, resulting in vision loss. There is currently no standard treatment for MMD. Transplantation of intact sheets of RPE and suspensions of isolated individual RPE cells as well as autologous translocation of RPE cells has been attempted as treatment for AMD. Human photoreceptors are comprised of two cell types-rods and cones. Both have a close relationship with the outermost retinal cells, the retinal pigmented epithelium (RPE). The RPE is located between the choroid and the photoreceptors. The RPE maintains photoreceptor function by recycling photopigments,delivering, metabolizing and storing vitamin A, phagocytosing rod photoreceptor outer segments, transporting iron and small molecules between retina and choroid, maintaining Bruch's membrane and absorbing stray light to allow better image resolution. In essence, the RPE layer is critical to the function and health of photoreceptors and the retina as a whole. Human PRE (hRPE) transplantation may be a viable option for treatment of degenerative diseases of the retina. MA09-hRPE cells are fully differentiated human RPE cells derived from embryonic stem cells. Transplanted hRPE cells prepared by Advanced Cell Technology have been studied in rodent models of macular degenerative disease. The data suggests that the subretinal injection of ACT's hRPE cell products rescues, or at least delays, loss of visual function in two animal models of retinal degenerative diseases. The main purpose of this study is to evaluate the safety and tolerability of MA09-hRPE cellular therapy in patients with Myopic Macular Degeneration (MMD). Another objective is to evaluate potential efficacy endpoints to be used in future studies of RPE cellular therapy.
GALATIR is a double blind randomized clinical trial comparing efficacy and safety of BCD-021 (bevacizumab) and Lucentis® (ranibizumab) in patients with neovascular wet age-related macular degeneration. The purpose of the study is to demonstrate the non-inferiority of efficacy and safety of BCD-021 compared to Lucentis®.
This will be an open-label, non-randomized multi-center study of adipose stem cell (ASC) implantation. ASCs will be derived from the patient's adipose or fat. Liposuction using local anesthesia and syringe collection will be performed to collect the adipose tissue specimen for subsequent processing to isolate the stem cells. The cells will be delivered via needle injection into the eye.
Age-related macular degeneration (AMD) is the leading cause of blindness in the Western World. The etiology and pathogenesis of this disease remain largely unknown. In Europe about two million people suffer from AMD. According to the Age-Related Eye Disease Study (AREDS) the disease can be classified into early, intermediate and late. Early age-related macular degeneration is characterized by the presence of small or medium-sized drusen and/or retinal pigmentary abnormalities. Intermediate age-related macular degeneration is characterized by large drusen or numerous medium-size drusen and/or geographic atrophy not extending to the center of the macula. Late age-related macular degeneration can be either atrophic with extension to the macula or neovascular. The late form of the disease is associated with a pronounced loss of visual acuity. In the recent years several studies focused on risk factors for late AMD and a recent systematic review and meta-analysis reported risk factors for AMD based on 16 studies in almost 114000 subjects. Strong and consistent associations with late AMD for found for increasing age, current cigarette smoking, previous cataract surgery, and a family history of AMD. Consistent associations between late AMD and higher body mass index, history of cardiovascular disease, hypertension and higher plasma fibrinogen were also found, but the association was weak. Inconsistent associations were found for gender, ethnicity, diabetes, iris color, history of cerebrovascular disease, serum total and HDL cholesterol and triglyceride levels. Evidence has also accumulated that other factors influence the risk for AMD. Several genetic risk factors have been identified in the last years including genes in the alternative complement pathway and the RMS2/HTRA1 region. In addition, post-hoc analysis of data from the AREDS study has indicated that reduced intake of the omega-3 free fatty acids eicosapentaenoic acid and docsahexaenoic acid are associated with the risk of late AMD thereby supporting previous population based studies. The AREDS study also revealed that reduced intake of the macular pigment lutein and zeaxanthin may be associated with late AMD, again supporting previous population-based studies. Finally, 2 small studies indicate that reduced choroidal blood flow is associated with an increased risk of developing late AMD. Less data are available for the progression of early or intermediate AMD and the associated risk factors. This is at least partially related to the problems in quantifying progression of drusen size and volume. In the recent years, however, significant efforts have been achieved in optical coherence tomography (OCT)-based methods for quantifying drusen progression and drusen volume. Polarization-sensitive OCT is the most promising of these approaches and will be used to quantify drusen area and volume in the present study.
This is a pilot study to evaluate the safety of the Model WA-NG telescope prosthesis in patients with bilateral moderate to profound central vision impairment due to end-stage age-related macular degeneration.

The objective of this study is to confirm the safety and to establish the effectiveness of low voltage external beam radiosurgery using the IRay System for the treatment of subjects with recurrent leakage secondary to neovascular Age-related Macular Degeneration (AMD) as determined by decreasing the number of Lucentis injections required during the first 12 months of the study.
