Primary Outcome Measures:
  • Safety of hESC derived RPE cells [ Time Frame: 12 months ]

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

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


Secondary Outcome Measures:
  • exploratory evaluations for potential efficacy endpoints [ Time Frame: 12months ]

    Secondary endpoints will be evaluated as exploratory evaluations for potential efficacy endpoints.

    • Change in the mean of BCVA
    • Autofluorescense photography
    • Reading speed

    Evidence of successful engraftment will consist of:

    • Structural evidence (OCT imaging, fluorescein angiography, slitlamp 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: 12
Study Start Date: September 2012
Estimated Study Completion Date: April 2016
Estimated Primary Completion Date: February 2016 (Final data collection date for primary outcome measure)
