Brief Summary:
The main objective of the study is evaluation of the safety and tolerability of RPESC-RPE-4W as therapy for dry AMD.

Condition or disease Intervention/treatment Phase
Dry Age-related Macular Degeneration Biological: RPESC-RPE-4W Phase 1 Phase 2

Detailed Description:

RPESC-RPE-4W is Allogeneic RPE stem cell (RPESC)-derived RPE cells (RPESC-RPE) isolated from the RPE layer of human cadaveric eyes are transplanted under the macular.

This first-in-human Phase 1/2a open-label dose-escalation interventional study plans to enroll a total of 18 subjects

Primary Outcome Measures :
  1. Safety and tolerability of RPESC-RPE-4W transplantation [ Time Frame: 24 months ]

    The transplantation of RPESC-RPE-4W cells will be considered safe and tolerated in the absence of:

    • Decrease in visual acuity (VA) of more than 15 Early Treatment Diabetic Retinopathy Study (ETDRS) letters (or to worse than counting fingers at three feet) from baseline
    • Any Grade 2 (CTCAE version 5) or greater Adverse Events (AE) related to the cell product and investigational interventions.
    • Any evidence that the cell are contaminated with an infectious agent or serious immune response to the cell product
    • Any evidence that the cells show tumorigenic potential


Secondary Outcome Measures :
  1. Change in the mean of Best Corrected Visual Acuity (BCVA) [ Time Frame: 24 months ]
    Change in visual acuity will be measured by ETDRS chart.

  2. Loss of ≥10 decibels of ten-degree average visual sensitivity microperimetry [ Time Frame: 24 months ]
    Loss of ≥10 decibels of ten-degree average visual sensitivity will by measured by microperimetry.

  3. Change in GA lesion area [ Time Frame: 24 months ]
    Change in GA lesion area will be measured.

  4. Evidence of structural changes [ Time Frame: 24 months ]
    Structural evidence will be measured by OCT imaging, autofluorescence, fluorescein angiography, and fundus photography
