Filter by:Study purpose: To evaluate if previously high-frequent (3-5 weekly) aflibercept treated neovascular age-related macular degeneration (nAMD) can be extended in their treatment interval when switched to faricimab. Primary objective: To assess the efficacy of faricimab compared to aflibercept in terms of durability at 32 weeks by extending treatment interval in previous high-frequent aflibercept treated nAMD.
Phase 2b, randomized, double-masked, parallel-group, active-controlled, multicenter, 36-week study designed to assess the safety and efficacy of suprachoroidally administered CLS-AX 1.0 mg with a flexible dosing regimen in participants with neovascular age-related macular degeneration previously treated with intravitreal anti-vascular endothelial growth factor (VEGF) standard of care therapy. Only one eye will be chosen as the study eye.
The goal of this study is to evaluate the safety and efficacy of LX102-C01 treatment of nAMD. This study will enroll subjects aged ≥ 50 years old to receive a single unilateral intravitreal (IVT) injection of LX102-C01 to evaluate its safety and efficacy.
This study is designed for multi-center, open-label, dose escalation phase I trial to evaluate the safety and tolerability of a single and multiple intravitreal injection of IBI333 in subjects with neovascular age-related macular degeneration (nAMD).
Neovascular or wet age-related macular degeneration (nAMD) is a degenerative ocular disease associated with the infiltration of abnormal blood vessels in the retina from the underlying choroid layer and is a leading cause of blindness in patients over 65 years of age. The abnormal angiogenic process in nAMD is stimulated and modulated by vascular endothelial growth factor (VEGF). Treatment of nAMD requires frequent intravitreal (IVT) injections of VEGF inhibitors (anti-VEGF) administered every 4-16 weeks. ADVM-022 (AAV.7m8-aflibercept) is a gene therapy product being developed for the treatment of nAMD and offers the potential for sustained intraocular expression of aflibercept following a single IVT injection. ADVM-022 is designed to reduce the current treatment burden which often results in undertreatment and vision loss in patients with nAMD receiving anti-VEGF therapy in clinical practice.
The study is designed for multi-center, randomized, double-masked, active-controlled study to evaluate the longer interval of intravitreal injection of IBI302 in subjects with neovascular age-related macular degeneration.
Age-related macular degeneration (AMD) is a chronic and progressive eye disease and is one of the leading causes of vision impairment globally. AMD is referred to as either the dry or the wet type, where the wet type (also called neovascular-AMD or nAMD) is a later stage of the disease with neovascularization and retinal edema being the main attributes. This will usually cause subacute distortion or loss of central vision in patients. Since 2004, a successful treatment alternative for nAMD has been ocular injections with anti-VEGF (anti-Vascular Endothelial Growth Factor), causing the neovascularization and edema to regress and vision to improve. However, injections have to be repeated, usually requiring 8 injections or more during the first year of treatment. This can cause both a risk for serious adverse effects and is a significant financial drain on health care resources. Patients undergoing treatment are at risk for retinal edema recurrence. The time interval tolerated between injections is individual, and the accepted treatment strategy of today is to gradually, in a stepwise manner, increase the interval between injections. For some patients this extension is well tolerated, but for many patients relapse of proliferations and retinal edema will recur. With state-of-the-art technology OCT-A (optical coherence tomography-angiography) in combination with the clinically, well established examination method of OCT (optical coherence tomography), the project group will study the phenotypic vessel and tissue changes that occur in between injections. Furthermore, the investigators will measure cytokines, chemokines and growth factors in blood samples and the tear film during different treatment stages to see if any single factor is prognostic for poorer response to treatment or relapse. In the short term, the project group hope that the knowledge gained from this project could lead to a better understanding of the mechanisms behind nAMD neovascular relapse and to apply this to routine screening in the clinics. In the longer term, the project group hope that elucidating the physical mechanisms and molecular changes could enable new targeted therapies to be developed. Aim 1: To characterize the phenotype of vessels in relapsing nAMD patients and compare to those without relapse using OCT-A imaging Aim 2: To investigate retinal edema and choroidal thickness in correlation with neovascular changes of relapsing nAMD Aim 3: To measure cytokines, chemokines and growth factors in the tear film before and during treatment with anti-VEGF for nAMD With our main hypothesis being: Relapse of nAMD in patients occurs principally through reconfiguration and vasodilatation of persistent non-regressed vessels following anti-VEGF treatment, while fully regressed vessels remain dormant
The study will compare the safety of ophthalmic bevacizumab in vials versus pre-filled syringes in subjects diagnosed with a retinal condition that would benefit from treatment with intravitreal injection of bevacizumab, including: exudative age-related macular degeneration, diabetic macular edema, or branch retinal vein occlusion.
This is a multi-center, randomized, double-blind, active-controlled study to evaluate the efficacy and safety of IBI302 in subjects with neovascular age-related macular degeneration.
This main long-term extension study is designed to evaluate the long-term safety and tolerability of faricimab 6 milligrams (mg) administered by intravitreal injection at a personalized treatment interval (PTI) to participants with neovascular age-related macular degeneration (nAMD) who enrolled in and completed one of the Phase III studies: GR40306 (NCT03823287) or GR40844 (NCT03823300), also referred to as the parent studies. Eligible patients who consent to participate in this main study will be enrolled upon completion of the end-of-study visit in the parent study. Additionally, there is a substudy that is being conducted. The aim of this substudy is to evaluate the impact of intravitreal faricimab on the health of the corneal endothelial cells in the study eyes of patients with nAMD to fulfill a U.S. Food and Drug Administration (FDA) post-marketing requirement. The fellow eyes of the same enrolled participants in the substudy will serve as the controls.
