Active clinical trials for "Neovascularization, Pathologic"

The primary objective of this protocol is to look at whether Lucentis (ranibizumab) is safe and effective when used for macular edema (retinal swelling) due to Eales' disease. The secondary objective is to see if macular edema comes back within three months after the last dose of study drug is given.

This study is designed to provide efficacy and safety data in patients with choroidal neovascularisation (CNV) secondary to myopia using an individualized as-needed (PRN) dosing schedule. Eligible patients who have provided written agreement to take part in the study will receive an intravitreal (into the study eye) injection of ranibizumab 0.5mg. Following eye examinations and tests at monthly clinic visits, the study doctor will repeat the injections on a monthly basis as required for an additional 11 months, in accordance with specified retreatment criteria. Patients will be in the study for approximately 12 months and will visit the hospital clinic 14 times over that period. The main assessments will include visual acuity tests, eye examinations, optical coherence tomography (OCT) to assess retinal thickness, fundus photography and fluorescein angiography (FA), measurement of intraocular pressure, blood pressure and pulse measurements and completion of health-related questionnaires'.

The leading risk factor for corneal transplant rejection is abnormal blood vessel growth of the host bed. Vascular endothelial growth factor (VEGF) is thought to be a mediator of this corneal neovascularization (NV), therefore we would like to test the safety and efficacy of local VEGF blockade in the promotion of graft survival in high risk corneal transplants.

To evaluate the safety and efficacy of the combination treatments in wet age-related macular degeneration. The combination treatment consists of verteporfin photodynamic therapy and either triamcinolone acetonide or pegaptanib added as an intravitreal injection.

This is a Phase IIIb, single-masked, 1-year multicenter study of the safety and tolerability of intravitreally administered ranibizumab in subjects with active subfoveal CNV secondary to AMD.

The purpose of the study is to determine whether the anti-VEGF drug is effective at stabilizing and/or improving vision in patients with the wet form of AMD

Age-related macular degeneration (AMD) represents the most common cause of blindness in patients over the age of 60. The major cause of vision loss in this disease is due to the development of choroidal neovascular membrane formation (CNVM). Several clinical trials have proven that eyes with "well-defined" CNVM or lesions that can be readily demarcated with fluorescein angiography can be successfully treated with laser photocoagulation. However, up to 87% of eyes present with "ill-defined" CNVM or lesions that cannot be well demarcated on fluorescein angiography and are not amenable to laser photocoagulation. No beneficial treatment for this form of choroidal neovascularization has been established. Histopathologic study has demonstrated the presence of inflammatory and reparative responses in the retina of patients with ill-defined choroidal neovascularization. Since corticosteroids have been shown to downregulate many of the cellular factors involved in both inflammation and repair, the present study is designed to assess the ability of corticosteroid injection around the eye to prevent severe vision loss associated with "ill-defined" choroidal neovascularization in the setting of age-related macular degeneration. The study will be organized as a randomized open label control clinical trial involving 2 phases. Phase 1 involving 40 patients will establish the feasibility and safety of this treatment modality. Phase 2 will place emphasis on efficacy of the study.

Neovascularization Induced by Mechanical Barrier disrUption and Systemic erythropoietin in patients with cerebral perfusion deficits (NIMBUS trial)

This multiple-center, multiple-dose and regimen, randomized, double-masked active comparator-controlled, double-masked, five parallel group, 36-week study will evaluate the efficacy, safety, tolerability, and pharmacokinetics of faricimab (RO6867461) in participants with choroidal neovascularization (CNV) secondary to age-related macular degeneration (AMD). The study was designed to allow the evaluation of RO6867461 in a treatment-naive population (comparison of Arms A, B, C, and D) and an anti-VEGF-incomplete responder population that met a predefined criterion at Week 12 (comparison between Arms A and E). Only one eye per participant was chosen as the study eye.

Inflammatory choroidal neovascularization (InCNV) is the third cause of CNV after myopia and Age-related Macular Degeneration (AMD). InCNV is a rare but severe disease and its treatment should not be delayed. InCNV is treated at the moment with off-label anti-VEGF (Vascular Endothelial Growth Factor) therapy and could also benefit from aflibercept (EYLEA), a new anti-VEGF currently indicated in AMD. Case reports suggest that such patients would not need as many injections as in AMD. ALINEA is an open-label, single arm, prospective, multicenter, phase II study. The main objective is to demonstrate the effectiveness in clinical terms after 52 weeks of treatment with aflibercept on the visual acuity of patients affected by InCNV. A specific dosage regimen is designed to achieve maximum efficiency. The patients are followed on a monthly basis until 52 weeks. The first injection is mandatory. The other ones are injected only in case of active InCNV.
