About this trial

This is an interventional treatment trial for Dry Age-related Macular Degeneration

Eligibility Criteria

55 Years - undefined (Adult, Older Adult)All SexesDoes not accept healthy volunteers

Inclusion Criteria:

  1. Clinical diagnosis of dry AMD.
  2. Ability to understand and give informed consent.
  3. Adult male or female >55 years of age.
  4. Medically suitable to undergo vitrectomy and subretinal injection (>60% on Karnofsky scale).
  5. Postmenopausal if female (expected to be common for the age limitation), or the female partner of a male subject unable to father children.
  6. If male, willing to use barrier and spermicidal contraception during the study.

Exclusion Criteria:

  1. Allergy or hypersensitivity to dilation drops or fluorescein.
  2. Active major medical conditions limiting ability to participate in the study.
  3. Active malignancy or treatment with chemotherapy.
  4. Systemic immunosuppressant therapy within past six months.
  5. History of toxoplasmosis, retinal histoplasmosis or tuberculosis.
  6. Receipt of investigational product (IP) in a clinical trial within prior six months.
  7. Any other medical condition, which, in the Investigator's judgment, will interfere with the subject's ability to comply with the protocol, compromises subject safety, or interferes with the interpretation of the study results.
  8. Pregnant or nursing females.

Outcomes

Primary Outcome Measures

Safety and tolerability of RPESC-RPE-4W transplantation
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

Change in the mean of Best Corrected Visual Acuity (BCVA)
Change in visual acuity will be measured by ETDRS chart.
Loss of ≥10 decibels of ten-degree average visual sensitivity microperimetry
Loss of ≥10 decibels of ten-degree average visual sensitivity will by measured by microperimetry.
Change in GA lesion area
Change in GA lesion area will be measured.
Evidence of structural changes
Structural evidence will be measured by OCT imaging, autofluorescence, fluorescein angiography, and fundus photography

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