Active clinical trials for "Choroidal Neovascularization"

CNV from AMD is the leading cause of blindness in people over 50 in North America. The hypothesis is to determine if there is an improvement in retinal function determined by ERG following treatment with ranibizumab for AMD

The purpose of this study will be to assess the safety and tolerability and dose-limiting toxicity of a single intravitreal injection of Sirna-027 (AGN211745) and to assess the anatomical changes in the retina, changes in CNV, and changes in visual acuity. Escalation to the next dose cohort will be completed following minimum of 2 weeks follow-up. Patients will be monitored intensively for three months, and then followed-up for safety up to 24 months post-injection.

Ranibizumab is a humanised recombinant monoclonal antibody fragment targeted against human vascular endothelial growth factor A. This study will assess the safety and efficacy of ranibizumab administered on an as-needed dosing regimen in patients with subfoveal choroidal neovascularization (CNV) secondary to age-related macular degeneration (AMD).

The purpose of the study is to detect persisting or early new activity of choroidal neovascularization (CNV) due to age related macular degeneration (AMD) during the first 12 months following the first ranibizumab dose at baseline as assessed by weekly high resolution optical coherence tomography (OCT). Detection of persisting or new signs of CNV activity at OCT triggers further ranibizumab treatments considering that any ranibizumab injections can maximally be applied as often as 2-weekly.

Prospective, single-center, randomized, clinical trial (RCT) comparing the time efficiency and safety of a single-use intravitreal injection (IVI) guide versus a traditional technique using a dual blade speculum among patients undergoing IVI for various indications.

This was a Phase II, multicenter, randomized, active comparator-controlled, 52-week study to investigate the efficacy, safety and pharmacokinetics of faricimab (RO6867461; RG7716) administered with extended dosing regimens in treatment-naive participants with neovascular age related macular degeneration (nAMD). Only one eye was chosen as the study eye.

This is an interventional, prospective, randomized, comparative monocentric study aiming to evaluate the safety and efficacy of Resveratrol to reduce the progression of exudative Age-Related Macular Degeneration.

The investigators hypothesize that it is safe and effective to treat patients with choroidal neovascularisation (abnormal blood vessels growing under the retina) secondary to causes other than age related macular degeneration (AMD) and pigment epithelial detachments (blisters of fluid under the retina) secondary to AMD with ranibizumab (Lucentis). These groups of patients have to date been excluded from the multicentre trials demonstrating significant benefit of Ranibizumab in the treatment of AMD.

This study was conducted to evaluate the efficacy and safety of 0.5 mg ranibizumab in adult and adolescent patients with visual impairment due to choridal neovascularization (CNV).

Age-related macular degeneration (AMD) is by far the most common disorder in the group of irreversible causes of visual disability. AMD leads to dysfunction and loss of photoreceptors in the central retina. Neovascular AMD (nAMD) affects visual function early in the disease process and severely compromises the highly developed functions of the macula, such as perception of details, central fixation, color vision, and reading ability. AMD-related visual impairment is associated with a loss of autonomy and quality of life. Current therapeutic approaches target vascular endothelial growth factor (VEGF), which has been identified as a main cytokine in the pathogenesis of nAMD. Ranibizumab, the fab-fragment of an antibody targeting VEGF is approved for the treatment of nAMD applied intravitreally in monthly intervals until the disease activity is stopped. However, a significant proportion of patients with nAMD suffer from persistent or recurring disease with the need of continuous anti-VEGF therapy over months and years, often leading to irreversible changes in the photoreceptor layer and the pigment epithelium. Recent studies regarding the treatment of nAMD utilized different forms of therapies, combining photodynamic therapy with verteporfin (PDT) and ranibizumab, as well as therapeutic regimen containing steroids. Even though these studies did not provide evidence that combination therapies are superior to ranibizumab monotherapy, studies were only conducted with patients with previously untreated nAMD. Therefore, currently there is no alternative therapeutic approach for patients with recurrent or persistent form of nAMD after multiple treatments with ranibizumab monotherapy. The purpose of this study is to assess the treatment effect of reduced fluence PDT and intravitreal ranibizumab versus intravitreal dexamethasone and ranibizumab versus intravitreal ranibizumab monotherapy in patients with persistent or recurrent choroidal neovascularization (CNV) due to AMD. The investigators hypothesis is that these findings will offer new insights in the management of persistent or recurrent CNV secondary to AMD.
