Arms Assigned Interventions
Experimental: Test (jCell injection)
single intravitreal injection of 1.0 x 10e6 human retinal progenitor cells into the eye with the poorest visual acuity or, if vision is comparable in both eyes, the non-dominant eye
Biological: human retinal progenitor cells
live suspension of 1.0 x 10e6 human retinal progenitor cells (hRPC) suspended in clinical grade medium injected intravitreally under local anesthesia
Other Name: jCell
No Intervention: Untreated Control
no treatment, the eye with the poorest vision in each Control subject will be documented and designated as the "study eye" for the purposes of endpoint analysis

Detailed Description:
There is no effective treatment for RP; once photoreceptors are lost, they do not regenerate. The rate of deterioration of vision varies from person to person, with most people with RP legally blind by age 40. Preclinical studies demonstrated that transplantation of retinal progenitor cells into the eye can result in both photoreceptor replacement and significant slowing of host photoreceptor loss. Thus, the primary goal of this therapy is to preserve, and potentially improve, vision by intervening in the disease at a time when dystrophic host photoreceptors can be protected and reactivated. Based on the demonstration of acceptable safety and tolerability in a phase 1/2a study, this phase 2b study is designed as a controlled comparison of the changes in visual function and functional vision in subjects who receive a single jCell injection in comparison to a comparable untreated control group of subjects with RP.
