Active clinical trials for "Macular Degeneration"

The purpose of this study is to compare the effect of PDT and TTT for the treatment of subfoveal occult CNV in age-related macular degeneration.

The study will evaluate whether taking a nutritional supplement designed to increase macular pigment in the eye can improve a person's ability to adjust to darkness. Patients will be assigned to take either a placebo or nutritional supplement for 8 months. Vision will be assessed at baseline, 4 months, and 8 months.

Age-Related Macular Degeneration (AMD) is a degenerative eye disease of the retina that causes a progressive loss of central vision. AMD is the leading cause of legal blindness among adults age 50 or older in the Western world. AMD presents in two different types - "dry" and the more severe "wet" form. Wet AMD is caused by the growth of abnormal blood vessels in the macula. Squalamine lactate is an investigational drug that may prevent the growth of these abnormal blood vessels. This study will test the safety and efficacy of Squalamine in the treatment of AMD.

The purpose of this study is to evaluate anatomical and functional effect of combination therapy of Squalamine Lactate Ophthalmic Solution, 0.2% administered twice daily with monthly ranibizumab intravitreal injections in patients with choroidal neovascularization due to AMD.

There are limited prospective data regarding the potential benefit and risks associated with switching between anti-VEGF therapies in patients with nAMD who have initially achieved a favorable response to the first anti-VEGF therapy used but subsequently have evidence of increasing disease activity despite continuation of therapy. This study will fill this knowledge gap by prospectively evaluating the effectiveness and safety of switching from aflibercept to ranibizumab in nAMD patients that have non - sustained response to initial treatment with aflibercept.

To evaluate the safety of 3 regimens of short-term, low-dose systemic IMT as rejection prophylaxis prior to and/or following transplant of MA09-hRPE cells.

This pilot study will evaluate the visual response to infrared (IR) in humans after dark adaptation. The investigators plan to determine which wavelength and intensity the human eye is most sensitive too, using a broad spectrum light source and wavelength-specific bandpass filters. The investigators will then evaluate the electrophysiologic response in healthy humans to IR, followed by studies in those with specific retinal diseases. The long-term goal of this research is to better understand the role that IR plays in visual function, and whether this can be manipulated to allow for vision in certain retinal pathologies that result from loss of photoreceptor cells. The investigators central objective is to test the electrophysiologic response to IR in the dark-adapted retinal and visual pathways. The investigators central hypothesis is that IR evokes a visual response in humans after dark adaptation, and the characteristics of this response suggest transient receptor potential (TRP) channel involvement. The investigators rationale is that a better understanding of how IR impacts vision may allow for an alternative mechanism for vision in a number of diseases that cause blindness from the degradation or loss of function of photoreceptor cells. The investigators will test the investigators hypothesis with the following Aims: Aim 1: To determine the optimal IR wavelength for visual perception in dark-adapted human participants. The investigators hypothesize that the healthy human eye will detect IR irradiation, with a maximum sensitivity at a specific wavelength. Using a broad-spectrum light source with wavelength-specific bandpass filters, the spectral range of visual perception to IR will be evaluated. The same will be done on colorblind participants. Aim 2: To test the electrophysiologic response to IR in healthy humans after dark adaptation. The investigators hypothesize that IR will elicit an amplitude change on electroretinography (ERG) and visual evoked potential (VEP) responses after dark adaptation in healthy human participants. Participants will be tested with both test modalities to evaluate their response to IR. Aim 3: To test the electrophysiologic response to IR after dark adaptation in humans with certain retinal diseases. Participants with retinitis pigmentosa, age related macular degeneration and congenital stationary night blindness, will be tested. Results will be compared to baselines and to those of healthy participants. The investigators hypothesize that there will be a response to IR on ERG and VEP, which will provide clues to the retinal cell layer location of the response to IR and the nature of potential TRP channel involvement.

To evaluate Ranibizumab as prophylaxis against the conversion to neovascular Age-Related Macular Degeneration

This is a Phase 1, randomized, double-masked, multicenter, parallel-assignment, pilot study to evaluate the safety, tolerability, initial clinical effectiveness, pharmacokinetics (PK), and immunogenicity of SCB-420 as compared with Eylea (aflibercept), in subjects with Neovascular Age-related Macular Degeneration. A total of 20 subjects with Neovascular Age-related Macular Degeneration will be enrolled across up to 11 sites in 3 countries (Australia, New Zealand, and China). The study will be conducted in 2 parts - Sentinel Safety Cohort and Open Enrolment. Subjects will be administered with 2 mg of SCB-420 or Eylea via intravitreal (IVT) injection every 4 weeks for a total 3 doses.

GALATIR is a double blind randomized clinical trial comparing efficacy and safety of BCD-021 (bevacizumab) and Lucentis® (ranibizumab) in patients with neovascular wet age-related macular degeneration. The purpose of the study is to demonstrate the non-inferiority of efficacy and safety of BCD-021 compared to Lucentis®.
