Active clinical trials for "Macular Degeneration"

The purpose of this study is to compare the effectiveness of intravitreal bevacizumab injection (IVBI) with respect to simple observation in patients with subfoveal choroidal neovascularisation (CNV) secondary to age-related macular degeneration (AMD) presenting at baseline with best corrected visual acuity (BCVA) less than 20/200.

The current norm in clinical practice for the treatment of choroidal neovascular membranes (CNVM) secondary to Age-related Macular Degeneration(AMD) involves monthly injections of Ranibizumab until the disease is stabilized. At this point, most physicians tend to follow one of two treatment regimens. 'Treat -and-observe' entails regular follow-up of stable patients, with treatment thereafter only in the presence of disease recurrence. Alternatively, in a 'treat-and-extend' dosing strategy, intervals between treatments are extended as long as disease remains stable. Many clinicians, who employ a treat-and-extend dosing regimen, do not extend their treatment intervals beyond 3 months. However, it is possible that the subgroup of patients on every three months 'treat-and-extend' dosing may represent a uniquely, stable population that would perform particularly well on an observational regimen with regular follow-up. We hypothesize that there will be a low CNVM recurrence rate in wet AMD patients stable on every three months Ranibizumab dosing ('treat-and-extend'), who begin a treat-and-observe protocol.

50 Patients with recalcitrant exudative age-related macular degeneration with a history of retinal or subretinal fluid after multiple intravitreal injections with ranibizumab 0.5mg and subsequently treated with ranibizumab 2.0mg, who are incomplete responders to 2.0mg of ranibizumab.

To establish the tolerability and preliminary efficacy of Cand5 by a single intravitreal injection in patients with wet age-related macular degeneration.

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.

Adalimumab is a humanized recombinant monoclonal antibody fragment targeted against tumor necrosis factor. This study will assess the safety and efficacy of intravitreal adalimumab administered in patients with choroidal neovascularization secondary to age-related macular degeneration non-responders to the conventional treatment with intravitreal ranibizumab.

The purpose of this study is to evaluate the safety, tolerability, pharmacokinetics and pharmacodynamics of the investigational drug ACU-4429 in subjects with geographic atrophy.

The primary objective is to assess long-term safety and tolerability of Intravitreal Aflibercept Injection (IAI; EYLEA®; BAY86-5321) in patients with neovascular AMD.

This study is a phase III, double-masked, randomized, study of the efficacy and safety of VEGF Trap-Eye in patients with neovascular age-related macular degeneration. Approximately 1200 patients will be randomized in Europe, Asia, Japan, Australia and South America.

This study is a double-masked, randomized, placebo-controlled study of the safety and preliminary efficacy of ATG003 (topical mecamylamine) in patients receiving maintenance injections of either ranibizumab or bevacizumab. Study Hypothesis: Mecamylamine could be effective in the treatment of neovascular AMD.
