Age Related Macular Degeneration and Stargartd Clinical Trial
Official title:
Intravitreal Bone Marrow-Derived Stem Cells in Patients With Macular Degeneration
The purpose of this study is to evaluate the behavior of intravitreal injection of of autologous bone marrow stem cells in patients with age related macular degeneration.
A prospective phase I/II, nonrandomized open-label study of agen related macular degeneration and Stargartd patients with best-corrected ETDRS visual acuity (BCVA) worse than 20/200. Standardized ophthalmic evaluation will be perform at baseline and at weeks 1, 4,12 and 24 (±1) following intravitreal injection of 10 x 106 bone marrow stem cells/ 0,1ml . Three measures will be used to evaluate the short-term safety of intravitreal of bone marrow stem cells: 1) severe visual loss, defined as a drop in 15 letters on ETDRS visual acuity scale; 2) decrease in ERG response; 3) decrease in 5 square degrees on visual field; secondary safety outcomes : 1) increase in intra-ocular inflammation defined herein as anterior chamber cells and flare higher than 3+ for more than 1 month after injection according to a classification described elsewhere ; 2) decrease in CMT more than 50um; 3)genesis of abnormal tissues (teratomas) or tumors; 4) qualitative changes in retinal or choroidal perfusion, like macular nonperfusion. Secondary outcome measures will be used to evaluate the short-term efficiency of intravitreal of Bone Marrow Stem Cells: 1) improvement in ERG response; 2) increase in visual field: 3) increase in CSMT > 50um and not related to macular edemar or choroidal neovascularization; 4) increase > 5 letters on BCVA ;
