About this study

Official title: Stem Cell Derived Retinal Pigmented Epithelium Implantation in Patients With Outer Retinal Degenerations: Phase I/II Clinical Trial

This study is a Phase I/II , open label,non randomized, prospective study to determine the safety of human embryonic stem cell derived Retinal pigmented epithelium (hESC RPE) sub retinal injections versus hESC RPE seeded on a polymeric substrate implanted in the sub retinal space,

Read the detailed description

To determine whether the surgical implantation of a human embryonic stem cell-derived retinal pigmented epithelium (hESC-RPE) monolayer seeded onto a polymeric versus hESC-RPE injections into the sub retinal space is a safe procedure.

6 Patients will receive hESC-RPE cell injections (100000 cells) in the sub retinal space (2 Dry Age-related macular degeneration (AMD), 2 Wet AMD with disciform scar and 2 with Stargardt's disease).

Also 5 patients Dry AMD, 5 patients with Wet AMD with disciform scar and 5 patients with Stargardt's disease with receive a subretinal implantation of the hESC-RPE seeded in a monolayer in a polymeric substrate.

Patients will be enrolled sequentially, and after the procedure the patients will be followed for 1 year.

Being tested
injection of hESC-RPE in suspension, injection hESC-RPE seeded in a substrate
Medical subject headings
Macular Degeneration, Stargardt Disease

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • injection of hESC-RPE in suspensionProcedure or surgery

    Also called Human Embryonic Stem Cell - Retinal Pigmented Epithelium

    The first six patients will receive a sub retinal injection of hESC-RPE in solution after a complete pars plana vitrectomy to access safety of the cell implant alone.

  • injection hESC-RPE seeded in a substrateProcedure or surgery

    Also called Human Embryonic Stem Cell seeded in a polymeric substrate

    Fifteen patients will receive a sub-retinal implantation of embryonic stem cell derived retinal pigmented epithelium seeded in a polymeric substrate to access safety of substrate seeded with RPE

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Incidence of Treatment-Emergent Adverse Events of sub retinal implantation of stem cell derived retinal pigmented epithelium in the sub retinal space.

    Incidence of surgical related side effects: Retinal detachment, Ocular inflammation, Increase in intraocular pressure, Infection( endophthalmitis), Loss of vision due to surgical, related complications

    Measured: 1 year

Secondary outcomes (1)
  1. Incidence of side effects related to the treatment itself( injection and implantation of sub retinal stem cell related RPE)

    Inflammation/rejection Cell migration/differentiation Tumor formation Proliferative vitreoretinopathy/Retinal detachment Implant migration

    Measured: 1 year

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing injection of hESC-RPE in suspension and injection hESC-RPE seeded in a substrate in people with Age Related Macular Degeneration and Stargardt's Disease, run by Federal University of São Paulo at 1 site in Brazil.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 2 inclusion and 2 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 22 Jul 2020. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Brazil. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this combined phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Incidence of Treatment-Emergent Adverse Events of sub retinal implantation of stem cell derived retinal pigmented epithelium in the sub retinal space. (time frame: 1 year). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 22 Jul 2020.
