Classification | Retinal Pigment Epithelial Cells (hES-RPE) | ||
Indication | Stargardt’s Macular Dystrophy (SMD) | Age-related Macular Degeneration (AMD) | Myopic Macular Degeneration (MMD) |
Significance | - World's first commercialization of embryonic stem cell therapy - Fundamental treatment for Macular Degeneration |
||
Characteristics | - Leads to gene mutation cause vision loss | - Affects older adults and results in loss of vision due to retinal damage - Increases patients as population aging |
- Occurs retinal abnormalities in serious short-sightedness |
Progress | - 2009 : Partnered with ACT (U.S) to introduce pipeline - 2010 : Received an orphan drug designation from U.S. FDA (Benefits include 7-year marketing exclusivity, tax credits, grants for clinical development, accelerated FDA approval, drug approval) |
||
- Clinical trial approval from U.S.FDA (2010.11) - Clinical trial approval from Korea MFDS (2011.05) |
- Clinical trial approval from U.S. FDA (2011.01) - Clinical trial approval from Korea MFDS (2012.05) |
- Clinical trial approval from U.S. FDA (2013.02) - Clinical trial approval from Korea MFDS (2013.10) |
|
Procedure | - Step 1 : Vitrectomy surgery - Step 2 : Subretinal transplantation of human embryonic stem cell-derived retinal pigment epithelial cells |
||
Outcome | - No safety issues related to the transplanted cells - Improved ETDRS visual acuity among subjects - Korea Study: 9-19 letters improvement in 3 patients from 4 patients analysis - U.S. and Europe Study: >15 letters improvement in 6 patients from 18 patients analysis |
- Clinical trial in progress |
