A Phase IIb Randomized, Multicenter Trial of Subretinal CPCB-RPE1 in Advanced Dry AMD (Geographic Atrophy)
A Phase IIb, Randomized, Assessor-Masked, Multicenter Clinical Trial to Assess the Safety and Efficacy of Subretinal Implantation of the CPCB-RPE1 Implant in Subjects With Advanced, Dry Age-Related Macular Degeneration (Geographic Atrophy) - PATCH AMD
Source: ClinicalTrials.gov · Last updated 23 Sept 2026
Brief summary (registry, in English)
This is a Phase IIb randomized, clinical trial designed to assess the safety and efficacy of unilateral implantation of the CPCB-RPE1 implant in subjects with geographic atrophy involving the fovea. Up to 6 surgical implantation sites will deliver the CPCB-RPE1 in this Phase IIb clinical trial. Additional study sites may serve as referral or follow-up sites. Twenty-four (24) subjects will participate in the trial and will be randomized 3:1 to one of 2 groups: * The treatment group receiving the CPCB-RPE1 implant (up to 18 subjects). * The control group receiving a simulated "sham" implantation procedure (up to 6 subjects)

Who cannot take part
Copied verbatim from ClinicalTrials.gov and grouped by topic. Only the trial team decides who can take part.
Criteria the registry did not label
- Eligible participants include:
- Age 55 to 90 years of age (inclusive), presenting with geographic atrophy involving the fovea in advanced, age-related, dry AMD.
- Clinical findings consistent with advanced dry AMD with evidence of one or more areas of ≥4.0mm2 but not exceeding 15.0 mm2 of geographic atrophy involving the fovea.
- Geographic atrophy defined as attenuation or loss of RPE as observed by biomicroscopy, OCT, or FAF.
- The best-corrected visual acuity (BCVA) of the eye to receive the implant will be ≥20/200 (35 EDTRS letters) to 20/63 (60 EDTRS letters) inclusive. The BCVA of the eye that is NOT to receive the implant will be better or equal to the eye that will receive the implant.
- Medically suitable to undergo pars plana vitrectomy and the surgical implant procedure, including being able to position post-operatively and use post-operative medications as required.
- Medically suitable for general anesthesia or monitored intravenous sedation, if needed.
- Pseudophakic in the study eye, to remove the risk of cataract formation following vitrectomy.
- Participants also must be willing and able to provide written, signed informed consent for this study.
- Participants able to complete the baseline microperimetry retinal sensitivity testing.
- On baseline microperimetry, participants must have ≥5 spots in the perilesional region with a retinal sensitivity between 3 and 17 Db.
