The CPCB-RPE1 Implant


The CPCB-RPE1 Implant


This investigational treatment includes using an implant (CPCB-RPE1) to replace some of the cells in the retina that have been lost or damaged due to Dry AMD.

The implant (CPCB-RPE1) is a small patch with a single layer of cells on a thin membrane which will be surgically inserted between the layers of your retina. 

Where do the cells come from?

The RPE cells were produced from human embryonic stem cells which were derived from a single embryo that was intended to be discarded but eventually donated for medical research. These stem cells have been thoroughly tested and approved for such use. 

The cells are put onto a very small membrane to make the implant.

* The implant is exclusively for use within the current clinical trial and not available for other experimental indications or compassionate use at this time.  


The surgical procedure


The Surgical Implantation Procedure


A vitreo-retinal surgeon will perform a standard small gauge vitrectomy. This is a very common retinal surgery.

A space will be created between the retinal layers where lost or damaged cells were located.

The implant is surgically inserted between the layers of the retina. The small implant has a thin layer of retinal pigment epithelial (RPE) cells. The same type of cells that have been damaged or lost in the eye in geographic atrophy.
