Primary Outcome Measures:
  • The safety and tolerance of transplantation of hESC-derived RPE cells MA09-hRPE [ Time Frame: 12 months ] [ Designated as safety issue: Yes ]

    The transplantation of hESC-derived RPE cells MA09-hRPE will be considered safe and tolerated in the absence of:

    • Any grade 2 (NCI grading system) or greater adverse event related to the cell product
    • Any evidence that the cells are contaminated with an infectious agent
    • Any evidence that the cells show tumorigenic potential

  • Safety Assessments [ Time Frame: 12 months ] [ Designated as safety issue: Yes ]
    • Adverse Event and Serious Adverse Event assessment
    • Clinical monitoring
    • Serial vital signs
    • Clinical laboratory tests
    • Directed ophthalmological monitoring
    • Monitoring of RPE cells acceptance/integrity/rejection
    • Monitoring of local and systemic infection
    • Monitoring of tumorigenic cell transformation


Secondary Outcome Measures:
  • Evidence of successful engraftment [ Time Frame: 12 months ] [ Designated as safety issue: No ]

    Evidence of successful engraftment will consist of:

    • Structural evidence (OCT imaging, fluorescein angiography, autofluorescence photography, slit-lamp examination with fundus photography) that cells have been implanted in the correct location
    • Electroretinographic evidence (mfERG) showing enhanced activity in the implant location


Estimated Enrollment: 16

Arms Assigned Interventions
Experimental: MA09-hRPE
Patients will undergo subretinal injection of MA09-hRPE
Biological: MA09-hRPE

Cohort 1 50,000 cells

Cohort 2 100,000 cells

Cohort 2a Better Vision 100,000 cells

Cohort 3 150,000 cells

Cohort 4 200,000 cells


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.
