In this pilot study the researchers will evaluate the safety and efficacy of 50% reduced fluence PDT combination therapy with ranibizumab. The researchers hope to gain information regarding the use of reduced fluence PDT combination therapy. The information gained from this pilot study may prompt further definitive studies comparing the safety and efficacy of both standard fluence PDT combination therapy, reduced fluence PDT combination therapy, and ranibizumab monotherapy. The study will compare the use of combination therapy with ranibizumab and verteporfin PDT to ranibizumab alone in patients with exudative age-related macular degeneration (AMD). All patients will receive three consecutive monthly treatments with ranibizumab. Patients will be randomized 1:1:1 to 3 groups. Patients randomized to group 1 will receive only ranibizumab. Patients randomized to group 2 will also receive one treatment with reduced fluence (50% fluence) verteporfin PDT at day 0. Patients randomized to group 3 will also receive one treatment with standard fluence verteporfin PDT. All patients will also be evaluated for possible retreatment with ranibizumab and verteporfin PDT according to established criteria. Thirty patients will be recruited from one U.S. sites. Randomization will occur at the time of entry into the study. Follow-up will continue until month 12 (from day 0) in all subjects.
The purpose of this study is to evaluate the safety and tolerability of intravitreal injections of ranibizumab in the treatment of AMD variants and other choroidal neovascularization (CNV) related conditions (Coats' disease, idiopathic perifoveal telangiectasia, retinal angiomatous proliferation, polypoidal vasculopathy, pseudoxanthoma elasticum, pathological myopia, multi-focal choroiditis, rubeosis iridis) using the incidence and severity of adverse events. Limited forms of treatment are available that limit the loss of visual acuity. However, the patients may not have any substantial improvement in acuity or function. Therefore there remains a significant unmet need for therapeutic options managing the neovascularization and its consequences. Lucentis (ranibizumab) injection will be considered as an attempt to control the growth of the abnormal vessels because of evidence suggesting that angiogenic factors, such as vascular endothelial growth factor (VEGF), play a role in the pathogenesis of neovascular non-AMD conditions. The rationale for the study design is as follows: A 0.5 mg dose of Lucentis (ranibizumab), a commercially available preparation that is Food and Drug Administration (FDA) approved and labeled for intravitreal injection use for neovascular (wet) age-related macular degeneration will be used. In AMD variants and other CNV related conditions, vascular endothelial growth factor (VEGF) plays a role in the pathogenesis as in neovascular AMD. Intravitreal injection of ranibizumab delivers maximal concentration of the antibody fragment to the vitreous cavity with minimal systemic exposure. The dosing schedule, based on considerations of the half-life and the clinical response in patients with neovascularization suggests that a 1-month interval is optimal.
This study will evaluate efficacy and safety for monthly ranibizumab 0.5 mg intravitreal injections in Asian patients with subfoveal choroidal neovascularization secondary to age-related macular degeneration.
The purpose of this study is to understand whether genes or certain factors in the environment determine how eyes will respond to Lucentis (ranibizumab) treatment. For example, whether having variants within specific genes means that a patient is likely to get better vision from treatment than another patient with different genes.
This is a trial aimed at patients with advanced wet macular degeneration and macular scarring treated wiht intravitreal injections of Lucentis.
The purpose of the project is to investigate in eyes with dry AMD, the efficacy and safety as preventive therapy of the immunomodulatory substance named copaxone which had been proven as safe and effective agent for a neurodegenerative disease, in arresting the progression as well as the conversion of dry AMD to wet AMD. The hypothesis that the immunomodulatory agent copaxone proven for a neurodegenerative disease may work in the eye is revolutionary and may open a new avenue of preventive treatment for the disease which is the major cause of legal blindness in the industrial world
First, to quantify, by means of comet assay analysis, systemic oxidative stress in patients with non-exudative and exudative age-related macular degeneration (AMD) and compare results to healthy controls. Second, to quantify systemic oxidative stress in patients with exudative AMD prior to and after photodynamic (PDT) therapy.
VERTACL will investigate whether a triple therapy, Avastin®, half fluence verteporfin photodynamic therapy (PDT), and triamcinolone acetonide-preservative free (TAC- PF), results in improved 12-month vision outcome compared to Avastin® alone in participants with neovascular AMD.
This is a two-part study to evaluate the safety, tolerability and pharmacokinetics of single (Part A) and repeat (Part B) eye drop doses of pazopanib in healthy adult and elderly subjects.
