Active clinical trials for "Angioid Streaks"

The purpose of this study is to investigate the safety and efficacy of intravitreal bevacizumab in patients with choroidal neovascularization associated with angioid streaks.

Angioid streaks are rare lesions associated to retinal pigment epithelium degenerations. They can be caused by general diseases as pseudoxanthoma elasticum, Paget's disease or drepanocytosis. Choroidal neovascularization (CNV) represents the most frequent complication for those patients. It leads to a rapid and important loss of visual acuity. CNV in angioid streaks represent the fourth leading cause of CNV in young patients. CNV in angioid streaks 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. ASTRID 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 CNV in angioid streaks. A specific dosage regimen is designed to achieve maximum efficiency. The patients are followed on a monthly basis until 52 weeks. Six injections are mandatory, the other ones are injected only in case of active CNV.

The purpose of this study is to determine whether injections of ranibizumab into the eye are safe and well tolerated when given to subjects in multiple doses.

Anti-VEGF therapy has been proven efficacious for the wet (neovascular) form of macular degeneration and may be beneficial for the treatment of choroidal neovascularization (CNV) due to other causes. The limitation of this type of treatment is the necessity for frequent intraocular injections. The purpose of this study is to determine if using anti-VEGF therapy in combination with photodynamic therapy can reduce the number of treatments needed with monotherapy while achieving similar visual results. There are ongoing multicenter trials evaluating combination therapy in patients with wet AMD but no similar trial for patients with CNV due to non-AMD causes. Therefore, in this study the investigators will focus on patients with CNV not due to AMD.

Intravitreal Bevacizumab is an effective treatment for choroidal neovascularization secondary to Angioid Streaks

The purpose of this study is to determine the effectiveness of antiangiogenic therapy to choroidal neovascularization secondary to angioid streaks.
