Primary Outcome Measures:
  • Safety of hESC derived RPE cells [ 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


Secondary Outcome Measures:
  • exploratory evaluations for potential efficacy endpoints. [ Time Frame: 12 months ] [ Designated as safety issue: No ]

    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, 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: 12
Study Start Date: April 2011
Estimated Study Completion Date: July 2013
Estimated Primary Completion Date: July 2013 (Final data collection date for primary outcome measure)
Intervention Details:
    Biological: MA09-hRPE Cellular Therapy
    • Cohort 1- 50,000 MA09-hRPE cells transplanted
    • Cohort 2- 100,000 MA09-hRPE cells transplanted
    • Cohort 3- 150,000 MA09-hRPE cells transplanted
    • Cohort 4- 200,000 MA09-hRPE cells transplanted
Detailed Description:

This study will be a phase I/II, open-label, non randomized, sequential, multi-center safety and tolerability trial to evaluate the effect of subretinal injection of human embryonic stem cell derived retinal pigment epithelium cells in patients with dry AMD and to perform exploratory evaluation of potential efficacy endpoints to be used in future studies RPE cellular therapy. Patients will be enrolled sequentially, and the clinical course of each patient treated will be reviewed by an independent Data Safety Monitoring Board (DSMB) before the next patient is enrolled.

Each eligible patient who signs a consent form and fulfills all (Inclusion/Exclusion) criteria will receive a single uniocular subretinal infusion of MA09-hRPE cells in one of four dose levels.

  1. Three patients - 50,000 cells transplanted
  2. Three patients - 100,000 cells transplanted
  3. Three patients - 150,000 cells transplanted
  4. Three patients - 200,000 cells transplanted

Six weeks after the first patient in each dose cohort receives the cell transplant, the DSMB will review the clinical data and recommend if the next two patients in the dose cohort may be treated. Each cohort of 3 patients will be reviewed by the DSMB when the 3rd patient completes 4 weeks of follow-up.

  Eligibility

Ages Eligible for Study:   55 Years and older
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No
