This is a proof-of-concept, first-in-human study evaluating a treatment called CPK850 in patients with retinitis pigmentosa, an inherited eye disease caused by changes in the RLBP1 gene. Patients aged 18-70 with an RLBP1 gene mutation confirmed by genetic testing may take part. The study was conducted in Phase 1/Phase 2 and has been completed.
The summary above is a plain-language rendering of the official record. The original English title is shown for reference.
Criteria are reproduced from the ClinicalTrials.gov record in the original English. Only the trial team can determine eligibility.
Inclusion Criteria: * Male and female patients aged 18 to 70 years inclusive. * The visual acuity in the study eye at the screening 1 visit should be no better than 60 ETDRS letters. * Clinical diagnosis of Bothnia dystrophy, Newfoundland rod-cone dystrophy or other progressive retinitis pigmentosa phenotype with mutations in the RLBP1 gene verified by genetic testing. * Visible photoreceptor (outer nuclear) and Retinal Pigment Epithelium (RPE) layers on standard OCT scan in the study eye at the screening 1 visit. Exclusion Criteria: * History of hypersensitivity to the study drug or to drugs of similar classes or to any of the medications required in the perioperative period. * Pre-existing eye conditions that would preclude the planned surgery or interfere with the interpretation of study endpoints * Any contraindication to the planned surgery or anesthesia as determined by the treating physician (surgeon, anesthesiologist, internist, or designee). * Women who are pregnant, or lactating or women of childbearing potential, defined as all women physiologically capable of becoming pregnant, unless they are using highly effective methods of contraception during dosing and for two months after treatment
