Active clinical trials for "Macular Degeneration"

The objectives of this study are to evaluate the safety and tolerability of ARC1905 intravitreous injection in subjects with geographic atrophy secondary to dry age-related macular degeneration (AMD).

Wet age-related macular degeneration is the most common cause of blind registration in the United Kingdom (UK). Standard treatment involves regular eye injections of a drug called ranibizumab (Lucentis). For most patients, ranibizumab maintains their vision but the effect of the drug is temporary, and they therefore require monthly hospital visits and typically six injections into the eye every year, probably for life. This study tests a new surgical device that delivers a focal dose of radiation (epimacular brachytherapy) to the macula (the part inside the back of the eye that gives fine central vision), to try and reduce or eliminate the need for ongoing, regular eye injections. The trial compares epimacular brachytherapy to ongoing standard treatment with ranibizumab. Whereas most studies of this new surgical device target patients who have not yet commenced any treatment, this study targets those who are requiring frequent eye injections, as there are limited surgical resources and these resources are best directed to those who have not fully responded to ranibizumab therapy, or whose response is shortlived. These patients have the most to gain from a device that may reduce their burden of treatment. The findings in untreated disease cannot be extrapolated to this discrete subset of patients, hence the need for a study that targets refractory disease. It is hypothesised that epimacular brachytherapy will reduce the frequency of Lucentis® (ranibizumab) re-treatment that patients require, whilst maintaining visual acuity.

To evaluate safety, visual acuity outcomes, persistence of choroidal neovascular leakage, and the number of treatments of combination intravitreal bevacizumab and verteporfin photodynamic therapy at standard or reduced fluence level in patients with subfoveal CNV due to age-related macular degeneration.

Palomid 529 is a dual TORC1/2 inhibitor of the PI3K/Akt/mTOR pathway having broad activity in angiogenesis and cellular proliferation. Palomid 529 will be examined to determine if the safety, tolerability and pharmacokinetic profile of single ascending doses when administered intravitreally or subconjunctivally.

This is a two-period study to evaluate the effect of repeat oral dosing of ketoconazole on the pharmacokinetics of single dose pazopanib administered as an eye drop

The aim of the study is to evaluate whether PF-04523655 is effective in the treatment of neovascular/wet AMD and at which dose.

This study will determine if a drug called sirolimus is safe to give to people with geographic atrophy GA and if it can help preserve vision in patients. GA is an advanced form of dry age-related macular degeneration (AMD). AMD affects the macula, the central part of the retina needed for sharp, clear vision. There are two types of AMD, wet and dry. In dry AMD, cells in the macula die.GA may at least partly be caused by inflammation. Sirolimus helps prevent inflammation and therefore may help treat GA. People with GA in both eyes with visual acuity between 20/20 and 20/400 in each eye may be eligible for this study. Participants undergo the following tests and procedures: Sirolimus injections in the study eye at each 3-month clinic visit. The drug is injected under the outer layer of the eye after the patient receives antiseptic and numbing drops. Antibiotic drops are continued for 2 days after the injection. Eye examinations before the first injection, 1 month after the first injection, during each clinic visit (11 to 15 visits over 2 to 3 years) and 3 months after the final injection. The examination includes testing visual acuity, measuring eye pressure and checking eye movements. To examine the inside of the eye, the pupil is dilated with eye drops. Regular photographs of the inside of the eye and optical coherence tomography photographs, which allow measurement of the thickness of the retina, may be taken during the eye examination. Autofluorescence imaging. The patient sits in a chair with his or her head placed in a chin rest in front of a camera. A light in the camera is used to scan the eye. Blood tests. Blood is drawn at the first visit and at up to seven study visits to check blood chemistries, such as liver and kidney function. Urine pregnancy test for women who are able to become pregnant.

This study is designed to compare four currently used types of anesthesia used prior to intravitreal injection in order to evaluate the most effective method of anesthesia in reducing pain and discomfort associated with intravitreal injections.

The purpose of the study is to evaluate the relative efficacy and safety of treatment of neovascular AMD with Lucentis on a fixed schedule, Avastin on a fixed schedule, Lucentis on a variable schedule, and Avastin on a variable schedule. A five year follow-up visit is being conducted in 2014 to gather information on long term outcomes.

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).
