• 1 other identifier: ChineseASZQ-001
• Study Type: interventional
• Target: 10
• Locations: 1 country

Brief Summary

This project intends to transplant human embryonic stem cells derived retinal pigment epitheliums into subretinal space of patients to treat dry age-related macular degeneration(dry-AMD).And we will assess the safety and efficacy of RPE transplants to treat dry AMD.

Conditions

Dry Age-related Macular Degeneration

Outcome Measures

Primary Outcomes (1)

• safety and tolerance of transplantation

  The safety and tolerance of transplantation of clinical grade hESC-derived RPE will be considered safe: no above moderate adverse events or severe adverse events which related to transplantation of retinal pigment epithelial cells ; Cells without infectious; No tumorigenicity. Through the clinical signs of subjects and laboratory examination to judge the tolerance, integrity, repellency of RPE cells, and monitoring the presence of local or systemic infection, and presence of metastatic tumor cells.

  one year

Secondary Outcomes (4)

• Efficacy:Early treatment of diabetic retinopathy eye chart (ETDRs)

  one year

• Efficacy：Best corrected visual acuity（BCVA）

  one year

• Efficacy：Optical coherent tomography (OCT)

  one year

• Efficacy：fundus autofluorescence
