Study Description

Brief Summary:

This study evaluates the changes in visual function at 12 months following a single injection of human retinal progenitor cells compared to sham treated controls in a cohort of adult subjects with RP.

Condition or disease	Intervention/treatment	Phase
Retinitis Pigmentosa	Biological: human retinal progenitor cells Other: Mock injection	Phase 2

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 sham-treated control group of subjects with RP.

Study Design


Study Type :	Interventional (Clinical Trial)
Actual Enrollment :	84 participants
Allocation:	Randomized
Intervention Model:	Parallel Assignment
Masking:	Double (Participant, Outcomes Assessor)
Masking Description:	Subjects, their family members and clinical staff performing key efficacy assessments will be masked to the randomization assignment of subjects. Due to the nature of some safety assessments and the sham treatment, not all personnel can be masked.
Primary Purpose:	Treatment

Arms and Interventions

Arm	Intervention/treatment
Experimental: Test (jCell injection) dose level 1 single intravitreal injection of 3.0 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 3.0 or 6.0 x 10e6 human retinal progenitor cells (hRPC) suspended in clinical grade medium injected intravitreally under local anesthesia Other Name: jCell
Sham treated Control a mock injection will be performed on the eye with the poorest vision in each Control subject (designated as the "study eye")	Other: Mock injection pressing the hub of a syringe with no needle against the eye to mimic intravitreal injection
Experimental: test (jCell injection) dose level 2 single intravitreal injection of 6.0 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 3.0 or 6.0 x 10e6 human retinal progenitor cells (hRPC) suspended in clinical grade medium injected intravitreally under local anesthesia Other Name: jCell
