Filter by: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.
This study will measure antibody levels in the blood of people with bleeding or swelling in the retina who have or have not been treated with bevacizumab (Avastin[Trademark]or ranibizumab (Lucentis[Trademark]). These drugs have been useful in reducing retinal bleeding and swelling in people with eye diseases that cause these symptoms, but the drugs' effects usually wear off and they have to be given repeatedly. In some patients, the benefits become less and less. It is possible that over time, patients taking these drugs may produce antibodies that act against the drugs, thus neutralizing their effects and preventing them from working properly. People 18 year of age and older who are participating in a current NEI protocol and meet the following criteria may be eligible for this study: - Are receiving injections of bevacizumab or ranibizumab for bleeding or swelling in the retina, but the treatment is becoming less effective - Are receiving injections of bevacizumab or ranibizumab for bleeding or swelling in the retina and the treatment is still effective - Have bleeding or swelling in the retina, but have never received either bevacizumab or ranibizumab Participants have blood samples drawn once when they start the study, once in the middle of the study, and once at the end of the study. They are asked permission for study researchers to review the results of their eye examinations at NIH.
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.
estimate the sensitivity of the HMP test in identifying visual field functional defects in subjects with CNV secondary to AMD
Demonstrate the ability of the current interactive tutorial and 1-800 support to teach an AMD patient to use the HMP device.
Neovascular age-related macular degeneration (AMD) is the leading cause of severe vision loss in the Western world. Intravitreal ranibizumab has recently become the treatment of choice for neovascular (AMD). Limitations to ranibizumab however include the high cost for the drug and the need for frequent intravitreal re-injections. The investigators' hypothesis is that when ranibizumab is combined with transpupillary thermotherapy (TTT) the number of necessary retreatments with Lucentis will be significantly reduced as compared to ranibizumab alone.
Demonstrate the ability of the current interactive tutorial and 1-800 support to teach an AMD patient to use the HMP device.
The primary objective of this study is to estimate the sensitivity of the HMP test in identifying visual field functional defects in subjects with CNV secondary to AMD, and differentiate them from intermediate AMD subjects.
The study is divided in two stages. The purpose of the first stage is to evaluate the percentage of subjects that can unpack the device, install it, learn the task and calibrate it according to their personal capabilities. The purpose of the second stage is to assess the ability of the subjects to perform reliable tests .
Patients with neovascular Age-related macular degeneration (AMD) and the particular feature of pigment epithelial detachments (PEDs) were not studied in the Phase III trials for ranibizumab (Lucentis). The PrONTO study was the first ranibizumab study to enroll such patients but only treated with ranibizumab until fluid within the layers of the retina was absent, not until the entire PED was absent. This study hypothesizes that there may be a difference in benefit between patients treated until just the retinal edema is gone and those in which the retinal edema and PED are both gone.
