Sub-retinal Transplantation of hESC Derived RPE(MA09-hRPE)Cells in Patients With Stargardt's Macular Dystrophy
A Phase I/II, Open-Label, Multi-Center, Prospective Study to Determine the Safety and Tolerability of Sub-retinal Transplantation of Human Embryonic Stem Cell Derived Retinal Pigmented Epithelial (MA09-hRPE) Cells in Patients With Stargardt's Macular Dystrophy (SMD)

Detailed Description
This study is a Phase I/II, open-label, non randomized, sequential, multi-center clinical trial. There will be 5 cohorts, the 4 low vision cohorts will contain 3 patients, the better vision cohort will contain 4 patients. The enrolled cohorts will be as follows:
Three SMD patients- 50,000 MA09-hRPE cells transplanted
Three SMD patients- 100,000 MA09-hRPE cells transplanted
Four Better Vison SMD patients- 100,000 MA09-hRPE cells transplanted
Three SMD patients- 150,000 MA09-hRPE cells transplanted
Three SMD patients- 200,000 MA09-hRPE cells transplanted
Patients will be enrolled sequentially, and within each cohort of 3 patients, each patient's clinical course over the first 6 weeks following cell transplantation will be reviewed by an independent (DSMB) before enrollment is opened for the next 2 patients. A full safety assessment of all 3 patients in each cohort will be made by the DSMB when the 3rd patient in each cohort completes 4 weeks of follow-up, and before the first patient in the next cohort receives a cell transplant. The exception is the better vision group where all patients may be enrolled once DSMB approval has been received.
Each cohort will be enrolled sequentially in turn, with the exception of the better vision cohort which may be enrolled in parallel with the other cohorts.
The day of the cell implantation will be Day 0, and patients will remain in the study until the last visit at 12 months.
