Filter by:Ranibizumab is a humanized anti-vascular endothelial growth factor (VEGF) monoclonal antibody fragment approved in Chile by the Instituto de Salud Pública for the treatment of diabetic macular edema (DME), retinal vein occlusion and age-related macular degeneration. Currently, there is limited epidemiologic information in Chile regarding the incidence of DME and limited experience of anti-VEGF hospital therapy. This study will evaluate the efficacy of intravitreal ranibizumab in Chilean DME patients, to investigate the anatomical and functional improvement following this treatment and to increase the local experience regarding the use of anti-VEGF in the treatment of diabetic macular edema.
This study will determine whether quarterly injections of Ranibizumab may prevent eyes with dry age-related macular degeneration from progressing to wet age-related macular degeneration (AMD).
The purpose of this study is to characterize emixustat hydrochloride pharmacokinetic and pharmacodynamic parameters in subjects with geographic atrophy associated with dry age-related macular degeneration.
The purpose of this study was to compare the development of new geographic atrophy in patients with wet Age-related Macular Degeneration (AMD) when treated with either ranibizumab or aflibercept over 24 months. Geographic atrophy is an advanced form of AMD that can result in the progressive and irreversible loss of visual function over time.
The administration of short courses of topical antibiotic drops before and/or after intravitreal injections is a common practice, but increasing evidence suggests this may not lower the risk of infectious endophthalmitis and could increase rates of antimicrobial resistance. The purpose of the present study is to determine the antimicrobial resistance profiles in patients who have received numerous (≥ 20) courses of antibiotics for intravitreal injection compared with untreated controls. This study compares 20 control patients without prior intravitreal injection to 20 patients who have undergone ≥ 20 prior intravitreal injections accompanied by a course of topical antibiotics for two days before and/or after the injection procedure. The lower, inner eyelid and nasal cavity were cultured and evaluated via disk diffusion method for antimicrobial sensitivity.
The purpose of this study is to examine the plasma concentration of vascular endothelial growth factor (VEGF) after standard treatment with one of the newest growth factor inhibitors, aflibercept (Eylea). Patients with exudative age-related macular degeneration (AMD) are treated today with anti-growth factors (anti-VEGF). Eylea appears to have a longer duration of action in the eye and a more powerful effect on the edema in the macula than previously used growth factor inhibitors. This means that the disease can be controlled with fewer number of injections into the eye and the investigators can therefore reduce the risk of complications associated with this type of treatment. It is unclear what the plasma VEGF concentration after treatment with Eylea into the eye in patients with wet age-related macular degeneration is.
The present trial will use an open label design to investigate the effect of BI 144807 on central 1-mm retinal thickness and presence of neovascular leakage in newly diagnosed wAMD patients. A further objective is to collect data on adverse events, vital signs, ECG and clinical laboratory parameters of BI 144807 in the same patient group.
The aim of this study is to test if PF582 (ranibizumab) is safe and similar to Lucentis (ranibizumab). Participants will have a screening visit to check for eligibility. Eligible participants will receive either PF582 or Lucentis, by injection into one eye on study Day 1, 28 and 56. Visits will be conducted on Day 2, 7, 14 80 and at 6 and 12 months. During the study participants will undergo the following procedures: height, weight and vital signs (blood pressure, pulse, temperature, breathing rate) measurement; medical and surgical history and concomitant medications; adverse event monitoring; physical examinations; eye tests (reading chart, measurement of retinal thickness [via pictures of the retina] and examination of the eye's blood vessels, via pictures taken following injection of a dye into the arm), blood collection and a urine pregnancy test, where applicable.
To collect data reflecting the efficacy and safety of aflibercept with and without photodynamic therapy in subjects diagnosed with the polypoidal choroidal vasculopathy subtype of wet age-related macular degeneration
Comparable data for bevacizumab and aflibercept are lacking, as are studies comparing the systemic levels of ranibizumab, bevacizumab, and aflibercept and their relative effects on circulating vascular endothelial growth factor. In the present prospective study, the investigators evaluated serum drug levels and plasma free vascular endothelial growth factor levels in patients with neovascular age-related macular degeneration following intravitreal injections of ranibizumab, bevacizumab and aflibercept.
