Active clinical trials for "Macular Degeneration"

The objectives of this study are to evaluate the safety, tolerability, and pharmacokinetic profile of E10030 intravitreous injection when administered as monotherapy or in combination with Lucentis® 0.5 mg/eye in subjects with subfoveal choroidal neovascularization secondary to age-related macular degeneration (AMD).

The purpose of this study is to evaluate the safety of combining juxtasclerally administered anecortave acetate 15 mg with triamcinolone acetate 4 mg administered intravitreally following photodynamic therapy with verteporfin for the treatment of exudative age-related macular degeneration (AMD).

Randomized controlled clinical trial of periocular corticosteroids as adjunctive therapy to photodynamic therapy (PDT) for patients with neovascular age-related macular degeneration (AMD). Patients undergoing PDT are randomized to either a periocular corticosteroid injection with 40 mg of triamcinolone acetonide or observation just prior to PDT. Patients are followed for 6 months. Primary outcome is leakage from choroidal neovascularization (CNV) at 3 months on fluorescein angiography.

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 is to evaluate the safety and tolerability of intravitreal injections of ranibizumab in the treatment of AMD variants and other choroidal neovascularization (CNV) related conditions (Coats' disease, idiopathic perifoveal telangiectasia, retinal angiomatous proliferation, polypoidal vasculopathy, pseudoxanthoma elasticum, pathological myopia, multi-focal choroiditis, rubeosis iridis) using the incidence and severity of adverse events. Limited forms of treatment are available that limit the loss of visual acuity. However, the patients may not have any substantial improvement in acuity or function. Therefore there remains a significant unmet need for therapeutic options managing the neovascularization and its consequences. Lucentis (ranibizumab) injection will be considered as an attempt to control the growth of the abnormal vessels because of evidence suggesting that angiogenic factors, such as vascular endothelial growth factor (VEGF), play a role in the pathogenesis of neovascular non-AMD conditions. The rationale for the study design is as follows: A 0.5 mg dose of Lucentis (ranibizumab), a commercially available preparation that is Food and Drug Administration (FDA) approved and labeled for intravitreal injection use for neovascular (wet) age-related macular degeneration will be used. In AMD variants and other CNV related conditions, vascular endothelial growth factor (VEGF) plays a role in the pathogenesis as in neovascular AMD. Intravitreal injection of ranibizumab delivers maximal concentration of the antibody fragment to the vitreous cavity with minimal systemic exposure. The dosing schedule, based on considerations of the half-life and the clinical response in patients with neovascularization suggests that a 1-month interval is optimal.

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.

To determine if Visudyne photodynamic therapy (low or very low fluence rate) combined with intravitreal injections of bevacizumab (Avastin) compared with bevacizumab alone will, with similar safety and efficacy, delay time to retreatment with bevacizumab after the initial treatment, in subjects with new wet AMD Hypothesis: PDT in combination with Avastin at either the low or very low fluence rate will delay time to retreatment and reduce the average number of treatments required, compared to Avastin alone, but will have a similar safety and efficacy profile.

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 this study is to compare the ability of different doses of pegaptanib sodium to safely and effectively minimize fluid leakage within the eye, thereby stabilizing or impriving vision in patients with wet AMD when compared to placebo injections.

This study will evaluate whether docosahexaenoic acid (DHA) dietary supplementation can improve macular function in patients with Stargardt macular dystrophy and Stargardt-like macular dystrophy. Stargardt macular dystrophy is a recessive inherited trait that causes a severe form of macular degeneration. (The macula is the center part of the retina in the back of the eye that is responsible for fine vision.) The disorder begins in late childhood and progresses to a significant decrease in central vision. One of the earliest signs of the disorder is accumulation in and under the macula of a fatty pigment called lipofuscin. Stargardt-like macular dystrophy is a dominant inherited trait involving loss of central vision, but it begins later than Stargardt macular dystrophy, and the accumulation of lipofuscin extends beyond the central region of the macula. DHA is a fatty acid that is essential for normal brain and eye development. It is normally found in the diet, but not in large amounts. Supplements may help prevent or slow the progression of some eye diseases. Patients with autosomal dominant Stargardt-like macular dystrophy or autosomal recessive Stargardt macular dystrophy are eligible for this study. Candidates will be screened with the following tests and procedures: Medical history and physical examination. Blood test to measure levels of DHA and vitamins. Eye examination: The patient's vision and eye pressure are tested, then the pupils are dilated to examine structures inside the eye. Photographs are also taken. Visual field test: The patient looks at a tiny spot of light projected onto a white screen and is asked to note when other lights appear at other places on the screen. Electroretinogram (ERG): An electrode (small silver disk) is taped to the patient's forehead. Drops are given to numb the eyes and special contact lenses are inserted in the eyes. For the first part of the test, the patient looks at the center of a black and white checkerboard screen that flickers for 30 seconds at a time. This is repeated 16 or more times. For the second part of the test, the patient looks inside a sphere, in which flashes of light flicker for 20 seconds at a time. This is repeated four or more times. The contact lenses sense small electrical signals generated by the retina during the tests. Participants will begin taking DHA capsules or a placebo (look-alike capsules with no active ingredient) from 1 week to 3 months after enrolling in the study and will repeat several of the screening tests at follow-up visits scheduled 3, 6, 9, 12, and 15 months after they start taking the capsules. They will also be interviewed about any treatment side effects.
