Investigating OpCT-001 for treating primary photoreceptor disease
Official title: A Phase 1/2a Study of Subretinal Administration of OpCT-001 Photoreceptor Precursor Cells Derived From iPSCs in Patients With Primary Photoreceptor Disease
Run by BlueRock Therapeutics · NCT06789445 · Data updated 2026-11-12
This study is testing a new treatment called OpCT-001 to see if it can safely help adults with primary photoreceptor diseases, like Retinitis Pigmentosa and Usher Syndrome, improve their vision.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are adults with a genetically confirmed diagnosis of primary photoreceptor disease and specific visual acuity criteria.
✕Probably not a fit
Patients with significant ocular conditions, recent ocular surgeries, or certain systemic health issues may not benefit from this study.

What this trial studies
This clinical trial evaluates the safety and tolerability of OpCT-001 in adults with primary photoreceptor diseases, including Retinitis Pigmentosa and Usher Syndrome. It consists of two phases: Phase 1 focuses on dose escalation and safety assessment, while Phase 2 aims to gather additional safety data and assess the impact of OpCT-001 on visual function and anatomical measures. Participants will be assigned to different cohorts based on their eligibility and will receive varying doses of the treatment. The study employs a randomized, masked design to ensure unbiased results.
Why it matters
Potential benefit: If successful, this treatment could improve visual function and quality of life for patients with inherited retinal diseases.
How similar studies have gone: While this approach is novel, similar studies targeting retinal diseases have shown promising results in the past.

Key Inclusion Criteria: * Confirmed genetic diagnosis of primary photoreceptor (PR) disease * Best corrected visual acuity (BCVA) in the study eye at Screening for Phase 1: Logmarithm of the minimum angle of resolution (LogMAR) 3.9 to LogMAR 1.3. BCVA at Screening for Phase 2: ETDRS letter score between 20 to 60, inclusive. * Retinal structure examination in the study eye demonstrating regions suitable for cell administration. Key Exclusion Criteria: * Clinically relevant, active ocular inflammation or infection * Glaucoma or other significant optic neuropathy * Diabetic macular edema or diabetic retinopathy * Clinically significant cystoid macular edema * In phakic participants: Spherical equivalent refractive error of greater than 8.00 diopters myopia * Ocular surgery ≤3 months before Screening * Monocular vision (ie, no light perception in the fellow eye) * Currently active malignancy, or history of malignancy within 5 years before OpCT-001 administration. Exception: Basal cell carcinoma that has been definitively treated. * Any current and active infection (bacterial/viral/fungal) that could put the participant at risk from immunosuppression * History of any cell therapy, gene therapy, or retinal implant at any time * Previously received a bone marrow or solid organ transplant
