Active clinical trials for "Macular Degeneration"

Single agent anti-VEGF therapies such as ranibizumab have shown great promise and have set the standard for visual outcomes in treating wet macular degeneration. However, they need to be administered frequently by intraocular injections with the attendant risk of endophthalmitis, lens damage, retinal detachment, and vitreous hemorrhage. The purpose of this trial is to see if using photodynamic therapy in combination with ranibizumab will decrease the number of treatments with ranibizumab.

This is a trial aimed at patients with advanced wet macular degeneration and macular scarring treated wiht intravitreal injections of Lucentis.

The purpose of this study is to compare 12-month results of two single initial treatments-photodynamic therapy with verteporfin alone and this therapy combined with intravitreal bevacizumab-for neovascular age-related macular degeneration, not including patients with polypoidal choroidal vasculopathy who were presumed to have age-related macular degeneration.

Ranibizumab is derived from a murine monoclonal anti- vascular endothelial growth factor (VEGF) antibody and can penetrate through the many retinal cell layers following intravitreal injection. The present study is directed towards the assessment of ranibizumab administered on the same day in combination with verteporfin in patients with subfoveal CNV secondary to ARMD

The purpose of this study is to provide compassionate use of anecortave acetate sterile suspension of 15 mg for a series of five patients as a means to control classic neovascularization following failure of treatment with photodynamic therapy using Visudyne.

The primary objective of this study is to assess whether compositional and functional alterations of the gut metagenome may be related to AMD. The primary variable for this assessment is the composition of the gut metagenome which will be analyzed by shotgun sequencing to characterize the faecal metagenome. The secondary endpoint is to assess whether single nucleotide polymorphisms in CFH, ARMS2, C3, PLEKHA1, HTRA-1, VEGF-A, VEGF-B, VEGFR and APOE genes which have been shown to be risk factors for the development of AMD and other macular diseases correlate with alterations in the gut metagenome .

Geographic atrophy (GA) causes the loss of the retinal pigment epithelium (RPE) cells in broad areas of the retina. The application of subthreshold micropulse laser spots in healthy RPE in the vicinity of the area of GA may restore the imbalance in survival factors caused by the disease (ie, the laser may decrease vascular endothelial growth factor and RPE-derived transforming growth factor beta, upregulation of pigment epithelium-derived factor). This may slow or even stop the enlargement of atrophy secondary to GA, and therefore, avoid further vision loss.

This clinical trial investigates the impact of intravitreal injection of Ranibizumab antibody on the acuteness of vision. Patients included are suffering from choroidal neo-vascularization (CNV) as a consequence of age-related macular degeneration (AMD). Initially, all patients get injections of 0.5 mg Ranibizumab in monthly intervals for 3 months. Subsequently, one group gets Ranibizumab in intervals of 2 months, whereas a second group is treated on demand. The primary end point of the study is the change of best-corrected visual acuity after 12 month. Secondary end points include the impact of Ranibizumab on morphological changes of the retina, the number of patients with gain or loss of 15 or more letters visual acuity after 12 months, changes in quality of life and the number of injections required during the first 12 months of treatment.

The investigators wish to better understand the role of the choriocapillaris (CC) in the formation and progression of non-exudative in age related macular degeneration (armd) by imaging the retinal pigment epithelium (rpe) and the choroidal microvasculature and by studying their inter-dependence to determine if the loss of the CC could prove useful as an anatomic clinical trial endpoint in future drug trials.

A multicentre, randomised, parallel group, sham-controlled, double-masked, dose-ranging study, investigating two doses of OPT-302 in combination with ranibizumab compared with ranibizumab with sham, over six consecutive monthly dosing cycles in participants with neovascular (wet) AMD.
