Study Summary
This trial is testing a cell therapy for retinitis pigmentosa, in which participants will receive a single injection of hRPC cells in one eye. The goal is to evaluate safety and tolerability, with some preliminary testing of efficacy.

Safety (Visual function measure: change in visual acuity)
Safety (Visual function measure: change in visual field: Goldmann visual field, microperimetry and FST)
6 months
Safety over the six months after treatment as assessed by the incidence of treatment emergent adverse events (TEAEs) and changes from baseline in other safety parameters.

Eligibility Criteria
Age 18+ · All Participants · 10 Total Inclusion Criteria
Mark “yes” if the following statements are true for you:The subject has the ability to consent to the study by providing a written signature on the consent form.
You must be an adult male or female over 18 years of age.
Study subjects must have a corrected ETDRS (Early Treatment Diabetic Retinopathy Study) visual acuity of 35 letters or less in the study eye for cohorts 1-5, a corrected ETDRS visual acuity of 63 letters (approximately 20/63) to 36letters (approximately 20/200) in the study eye for cohorts 6-8, and a corrected ETDRS visual acuity of 8 letters (approximately 20/800) to 68 letters (approximately 20/50) for cohorts 9 and on.
The test should be able to be completed without difficulty, and the patient's fixation and consistency between readings should be consistent enough to allow for the accurate detection of changes in retinal sensitivity.
You must be medically able to undergo a surgical procedure to remove the vitreous gel from your eye and an injection into the space below your retina.
The patient's serum chemistry and hematology are normal
There is no history of cancer in other parts of the body, except for some cases of non-melanoma skin cancer
This person has negative serology for human immunodeficiency virus (HIV), hepatitis B (HBV), hepatitis C (HCV), meaning that they have not been infected with any of these viruses.
The person is fit enough to have surgery that may require general anesthesia, as well as to undergo a short course of systemic corticosteroid therapy.
People who have RP have a clinical diagnosis based on one or more of the following: clinical features, medical imaging, electrophysiological measures and genetic testing, if available
