11 Clinical Trials for Various Conditions
This is a multicenter study designed to evaluate usability of ranibizumab PFS in patients with neovascular age related macular degeneration or macular edema secondary to retinal vein occlusion.
This study seeks to compare dexamethasone implant with rescue intravitreal ranibizumab to monthly intravitreal ranibizumab for the treatment of macular edema secondary to branch or central retinal vein occlusion. This is based on the null hypothesis that dexamethasone implant with rescue ranibizumab has inferior best corrected visual acuity at six months compared to monthly ranibizumab alone.
Researchers are looking for a better way to treat people who have macular edema secondary to retinal vein occlusion (RVO). In people with RVO, a blood vessel that carries blood away from the retina (vein) becomes blocked. The retina is the very back part of the eye. The blocked vein causes fluid and blood to leak into the retina and thereby causes a swelling of the macula (the center of the retina responsible for fine vision). This swelling is called macular edema. When a vein in the retina is blocked, the levels of a protein called vascular endothelial growth factor (VEGF) rises. VEGF helps the growth of new blood vessels. This can lead to macular edema and may cause the vision to become blurry. The study treatment intravitreal (IVT) aflibercept is given as an injection into the eye. It works by blocking VEGF and this can help repair vision problems related to RVO. IVT aflibercept is already available and is prescribed by doctors as the standard of care treatment for macula edema secondary to RVO. Standard of care is a treatment that medical experts consider most appropriate for a disease. Standard of care is given every 4 weeks in people with macula edema secondary to RVO. While repeated injections of aflibercept may prevent worsening of vision, it may place a burden on the patient. However, a higher amount (8 mg) compared to the standard of care (2 mg) of IVT aflibercept is being tested in studies. This higher amount could be given less often. The amount of IVT aflibercept given is measured in milligrams, also known as mg. The main purpose of this study is to learn how well a higher amount of the study treatment aflibercept works in people with macular edema secondary to RVO. To answer this, researchers will measure changes in vision called best corrected visual acuity (BCVA) in the study participants between study start and after 36 weeks of treatment. Changes will then be compared between those participants who received the higher amount of IVT aflibercept and those that received standard of care. To learn how safe the study treatment is in the participants, the researchers will count the number of participants from study start and up to 64 weeks later that have: * adverse events * serious adverse events "Adverse events" are any medical problems that the participants have during a study. Doctors keep track of all adverse events that happen in studies, even if they do not think they might be related to the study treatments. An adverse event is considered "serious" when it leads to death, puts the participants' lives at risk, requires hospitalization, causes disability, causes a baby being born with medical problems or is otherwise medically important. Dependent on the treatment group, the participants will either receive the higher amount of aflibercept or standard of care as an intravitreal injection for up to 60 weeks. The study will consist of a test (screening) phase, a treatment phase and an end of study phase. Each participant will be in the study for up to 64 weeks. One visit to the study site is planned during the screening phase, followed by visits approximately every 4 weeks (16 in total) during treatment and one visit at the end of the study. During the study, the study doctors and their team will: * check patients' eye health using various eye examination techniques * measure patients' eye vision (BCVA) * take blood and urine samples * do physical examinations * check vital signs * examine heart health using electrocardiogram (ECG) * do pregnancy tests in women of childbearing age In addition, participants will be asked to fill a questionnaire on vision-related quality of life.
This is a Phase III, multicenter, randomized, double-masked, active comparator-controlled, parallel-group study evaluating the efficacy, safety, and pharmacokinetics of faricimab administered by intravitreal (IVT) injection at 4-week intervals until Week 24, followed by a double-masked period of study without active control to evaluate faricimab administered according to a personalized treatment interval (PTI) dosing regimen in participants with macular edema due to branch retinal vein occlusion (BRVO).
The purpose of this study was to evaluate the efficacy and safety of brolucizumab in treatment of patients with macular edema (ME) secondary to central retinal vein occlusion (CRVO).

Eyetech Pharmaceuticals Inc. and Pfizer, Inc. are studying an investigational drug, MacugenTM, for the possible treatment of CRVO. An investigational drug is one that has not been approved by the U.S. Food and Drug Administration (FDA). This investigational drug may slow the growth of abnormal blood vessels in the eye and may reduce tissue swelling in the eye. The purpose of this study is to compare the safety and efficacy of a Macugen™ injection to a "pretend" injection. In addition, the purpose of this study is to measure the action of the study drug in the body over a period of time and to check for the presence of the study drug in your blood (called pharmacokinetics or PK). This study will involve approximately 90 people. People who decide to participate will have an equal chance (1 in 3) to receive one of three study injections, two of which are Macugen™ and one of which is a "pretend" injection.
This is a phase 3 study to determine the efficacy of VEGF Trap-Eye injected into the eye on vision function in subjects with macular edema as a consequence of central retinal vein occlusion.
This is a Phase III, multicenter, randomized, double-masked, active comparator-controlled, parallel-group study evaluating the efficacy, safety, and pharmacokinetics of faricimab administered by intravitreal (IVT) injection at 4-week intervals until Week 24, followed by a double-masked period of study without active control to evaluate faricimab administered according to a personalized treatment interval (PTI) dosing regimen in patients with macular edema due to central retinal vein occlusion (CRVO) or hemiretinal vein occlusion (HRVO).
Central and branch retinal vein occlusions are major causes of visual loss. Hemorrhage and capillary nonperfusion, when they involve the macula, can contribute to visual loss, but the major cause is macular edema. Focal and grid laser photocoagulation can sometimes provide benefit in patients with macular edema due to branch vein occlusions, but several laser treatments are often needed and recovery of vision can be very slow and incomplete 1. Laser photocoagulation does not provide benefit for macular edema due to central vein occlusions 2. Therefore, new treatments are needed.The objective of this study is to assess the bioactivity of 3 intravitreous injections 0.5 mg or 0.3 mg of ranibizumab in patients with macular edema due to central and branch retinal vein occlusions and correlate activity with peak and trough aqueous levels. The purpose of this research protocol is pilot study to determine if a randomized placebo controlled trial is warranted.
This study will assess the safety and efficacy of FA Intravitreal Inserts in subjects with macular edema secondary to RVO.
