Filter by:The primary objective is to assess the safety of intravitreal (IVT) Zimura® administered in combination with anti-VEGF Therapy (AVASTIN®, EYLEA®, OR LUCENTIS®) in anti-VEGF treatment experienced subjects with neovascular age-related macular degeneration (AMD)
Researchers are looking for a better way to treat people who have neovascular (wet) age-related macular degeneration (nAMD or wet AMD). In people with wet AMD, the body makes too much of a protein called vascular endothelial growth factor (VEGF). This causes too many blood vessels to grow in the area of sharpest vision in the eye, called macula. Fluid buildup due to leakage from these vessels can damage the macula, leading to vision problems such as blurring or a blind spot in the central (straight ahead) vision needed for reading or face recognition or car driving. Wet AMD is common in people aged 50 and older. The study treatment intravitreal aflibercept (also called BAY865321) is injected into the eye. It works by blocking the VEGF protein and thus reduces blood vessel growth. It has already been approved for patients with wet AMD to be given as intravitreal injection monthly at start and then every 8 weeks or longer. Repeated injections of aflibercept prevent worsening of vision but place a burden on the patient. Doctors try to increase the time between injections (treatment interval) in routine clinical practice based on individual patient needs. This is called treat and extend (T&E). Treatment intervals are stepwise extended or shortened depending on how the treatment works. This is checked with optical coherence tomography (OCT), an imaging technique used to observe relevant changes in the eye. The main purpose of this study is to learn how well aflibercept works if treatment intervals are extended faster (timepoint of extension is the same for both treatments arms), compared to standard T&E regimen in people with wet AMD in a preselected patient population with no fluid after treatment initiation. To answer this, researchers will assess changes in vision called best corrected visual acuity (BCVA) between study start and after 36 weeks. Changes will then be compared between participants whose treatment intervals were extended early and those on standard T&E regimen. All participants will receive 2 mg aflibercept as intravitreal injection for up to 52 weeks in intervals of every 4 to 16 weeks. Each participant will be in the study for up to 56 weeks. During this time 4 visits to the study site are set for all participants. The other visits are set individually. A final phone call is planned 3 days after treatment at the end of study. During the study, the doctors and their study team will: - check patients' eye health using various eye examination techniques (slit lamp microscopy, OCT, and ophthalmoscopy) that may necessitate eye drops to widen the pupil) - measure patients' eye vision (BCVA) - do physical examinations - check vital signs - ask the participants questions about how they are feeling and what adverse events they are having. An adverse event is any medical problem that a participant has during a study. Doctors keep track of all adverse events that happen in studies, even if they do not think the adverse events might be related to the study treatments. In addition, participants in the fast extension arm will be provided with a home monitoring OCT device.
BESRA is a national, multi-center, prospective, observational study to assess the effectiveness of brolucizumab intravitreal injections in patients with nAMD treated in the UK.
Age-related macular degeneration (AMD) remains a leading cause of blindness in United States and can be broadly divided into two forms: non-neovascular AMD (NNVAMD) and neovascular AMD (NVAMD) AMD. Among the several mechanisms underlying AMD, hypoxia and oxidative stress have been implicated and cause upregulation of several signaling proteins. About 20% of patients with NNVAMD develop choroidal neovascularization and hence convert to NVAMD. Upregulation of vascular endothelial growth factor (VEGF) plays a critical role in conversion from NNVAMD to NVAMD. Connective tissue growth factor (CTGF) is a polypeptide that has been shown to be overexpressed in various fibrotic disorders, suggesting its involvement in scarring. After the development of choroidal neovascularization, subretinal fibrosis may occur and result in permanent reduction of vision. An important question is, does CTGF contribute to subretinal fibrosis. An important first step in addressing this question is to determine if CTGF levels are increased in the eyes of patients with NVAMD and this is the objective of this study. The investigators plan to measure levels of connective tissue growth factor (CTGF) in the aqueous humor of patients with neovascular age-related macular degeneration and compare to controls. Levels of VEGF will be measured as a positive control.
A three-year, non-randomized, observational, multicenter prospective nAMD study - patient registry.
This is an open-label, dose-escalating, 48-week study assessing the safety, tolerability, bioactivity and duration of action of a single intravitreal injection of 0.1 mg, 0.25 mg, or 0.5 mg AXT107 in approximately 18 subjects (up to 6 subjects per dose) with nAMD.
Following the degeneration of the macula and the loss of central vision, the patients naturally relocate the fixation point for high visual acuity peripherally, in an eccentric and healthy part of the retina (PRL), to compensate for visual impairments. However, in many cases, the PRL lands on a sub-optimal retinal area and becomes useless. Modern low-vision rehabilitation procedures for AMD patients include biofeedback training (BFT) to relocate the PRL to a healthy retinal patch and acquire better fixation skills. This study seeks to combine BFT with home-based immersive virtual-reality audiovisual stimulation and measure feasibility and potential effectiveness on oculomotor control and visual perception.
This study is designed to investigate the safety and tolerability of GEM103 IVT injection + standard of care vs. sham + standard of care.
This study is designed to investigate the safety, PK/PD, biomarker and early clinical effects of repeat GEM103 IVT injections.
The purpose of this study is to evaluate the long-term safety and tolerability of intravitreal (ITV) injections of galegenimab (FHTR2163) administered every 4 weeks (Q4W) or every 8 weeks (Q8W) in participants with geographic atrophy (GA) secondary to age-related macular degeneration (AMD) who completed the parent study (NCT03972709/GR40973).
