Biological Human primary Retinal Pigment Epithelial (HuRPE) cells

HuRPE will be transplanted by a board-certified vitreoretinal surgeon, which will be administered into the subretinal space of experimental eye through a standard surgical approach.

low dose group Experimental

300,000 HuRPE cells

middle dose group Experimental

500,000 HuRPE cells

high dose group Experimental

1,000,000 HuRPE cells
