Active clinical trials for "Macular Degeneration"

Treatment of exudative age-related macular degeneration has been significantly improved by the advent of Lucentis™( which provides improved vision rather than simply stabilization) is common; however, monthly injections may be required to maintain this effect. It is hypothesized that sustained release fluocinolone acetonide will allow maintenance of the improved vision with fewer Lucentis injections.

The objectives of this study are to evaluate the safety, tolerability, and pharmacokinetic profile of multiple doses of ARC1905 intravitreous injection when administered in combination with multiple doses of Lucentis® 0.5 mg/eye, or with one induction dose of Lucentis 0.5 mg/eye in subjects with subfoveal choroidal neovascularization secondary to age-related macular degeneration (AMD).

This study is a phase 3, 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 the US and Canada.

The purpose of this study is to determine the way and rate that the study medication, JSM6427 a potent, highly specific integrin α5β1-antagonist is absorbed, broken-down and eliminated from the body when it is given as a single dosage strength by injection into the eye. Repeated dosages will also be given to determine the highest safe dose.

This randomized, controlled clinical trial will test the efficacy of Problem-Solving Treatment (PST) to improve vision function in older persons with age-related macular degeneration (AMD). AMD is a highly prevalent, disabling disease of aging that causes severe vision loss and functional decline. It is the leading cause of blindness in older persons in the United States and may affect more than 10 million people. Currently, there are no effective treatments to restore vision. Thus, improving Vision Function is a major goal of treatment. Vision function refers to vision-related abilities to perform daily living activities (e.g. reading recipes to prepare meals). Decrements in vision function will become a major public health problem as the population ages and the prevalence of AMD increases. PST is a brief, standardized, cognitive-behavioral treatment that teaches problem-solving skills. We believe PST will enable patients with AMD find practical solutions to vision-related problems and thereby improve vision function. We will recruit 240 AMD patients from the retina clinics of Wills Eye Institute, Philadelphia, PA, with bilateral AMD and visual acuity worse than 20/70 in the better eye. PST-trained therapists will deliver 6 1-hour, in-home sessions to the 120 subjects randomized to PST. The control treatment is Supportive Therapy (ST), a similarly structured, standardized psychological treatment that controls for the non-specific effects of treatment (n=120). ST contains no active elements beyond its non-specific components; in this way it is a placebo treatment. Independent raters, masked to treatment assignment, will assess Targeted Vision Function (primary outcome) and vision-related quality of life (secondary outcome) at 3 months to assess PST's efficacy, and at 6 months to evaluate its long-term effects. As the population ages, the disability of AMD will become more prevalent, costly, and burdensome to patients, families, and ophthalmologists. This makes devising and testing practical and affordable interventions to improve vision function a national priority.

To report the short term anatomic and visual acuity response after intravitreal injection of bevacizumab (Avastin, Roche, Rio de Janeiro, Brazil) in patients with choroidal neovascularization secondary to age-related macular degeneration.

The purpose of the study is to provide efficacy and safety data for monthly ranibizumab 0.5 mg intravitreal injections in Chinese patients with subfoveal choroidal neovascularization (CNV) secondary to age-related macular degeneration (AMD). The study results will support the regulatory submission in China to make ranibizumab available for clinical use.

Patients with low vision (visual acuity 20/400 or worse) were excluded from the large Phase III ranibizumab clinical trials. It is not known if treatment with ranibizumab results in improved visual function in such patients.Since ranibizumab has been shown to be the most effective therapy for exudative macular degeneration we propose to treat all patients in this study with monthly ranibizumab intravitreal injections. Patients will be assigned to one of two groups by the flip of a coin. Group #1 for "heads" and Group #2 for "tails". Group #1 patients will be treated for 3 monthly injections of 0.5 mg of ranibizumab and then as needed therapy. Group #2 will be treated with 6 monthly injections of 0.5 mg of ranibizumab and then as needed therapy.

This study was conducted in two parts; Part A and Part B: Part B was initially planned to include two cohorts. Cohort 2 was cancelled following an interim analysis for efficacy in Part A of the study, and not due to any safety issues or concerns. Cohort 2 is not referred to again and part B cohort 1 is referred to as part B alone in the remainder of the document and is the subject of this report. Part B was conducted to assess the safety and tolerability of a single intravitreal (IVT) LFG316 10 mg/100 µL injection. There was no efficacy evaluation in Part B. The study employed a multicenter, randomized, sham - controlled, single masked design. Eight patients with advanced AMD were planned to be randomized in a 3:1 ratio to receive a single IVT dose of LFG316 (10 mg/100 µL) or sham injection. Patients assigned to a sham injection were treated the same as those assigned to LFG316, except that the hub of an empty syringe (without needle) was placed against the eye instead of the IVT injection.

Ranibizumab has been proven to be effective in large multicentre studies. However, the injections have to be repeated monthly. A combined therapy with the established photodynamic therapy might even be more effective, less intravitreal injections might be necessary due to a synergistic effect. The study will be conducted to explore whether intravitreal ranibizumab in monotherapy or in combination with verteporfin photodynamic therapy under a new time regime is an effective, safe and convenient treatment for patients with subfoveal Choroidal Neovascularisation (CNV) secondary to Age-Related Macular Degeneration (AMD).
