About this trial

This study evaluates the safety of a single injection of jCell (famzeretcel) comprising 6.0 million (6.0M) retinal progenitor cells over a six-month study period in a cohort of adult subjects with RP. Additionally, changes in visual function will be evaluated at six months between the active treatment group (6.0M jCell) compared to sham-treated controls.

Eligibility criteria

Qualifiers

Clinical diagnosis of RP supported by at least 2 of the following clinical findings: (1) Loss of peripheral vision on formal visual field testing, (2) Symptoms of night blindness or difficulty adjusting to dim light, or (3) Optical coherence tomography (OCT) outer retinal atrophy consistent with RP.

Electroretinography (ERG) results that support diagnosis of RP including nondetectable or severely reduced rod responses (defined as less than 30% of the lower limit of normative values for the ERG lab performing the test), with prolonged implicit time OU (i.e., ensure bilateral involvement) and greater rod than cone loss. If genotyping results from a certified genetic testing lab document mutations clearly diagnostic of RP, with no other potential diagnosis of a disease(s) distinct from RP, the genetic test may be used in lieu of an ERG.

Subject age ≥ 18 years and ≤ 60 years at time of signing of consent.

Interocular BCVA disparity ≤ 15 letters.

Disqualifiers

Participation in any clinical trial of a drug intervention within the last 6 months, with the exception of a N-acetyl cysteine (NAC) study.

History of ocular treatment with any non-approved, experimental, investigational or neuroprotectant therapy (systemic, topical, intravitreal) or device in either eye, including previous jCyte clinical trials. Individuals with a history of NAC treatment may take part in the study following a 7-day washout period (prior to Baseline testing).

Subject is currently breast feeding/pumping or is planning to breast feed/pump during the 12 months after study treatment.

Subject is pregnant or intends to become pregnant less than 12 months after jCell injection.
