About this study

Official title: Follow-up to 5 Years of a Phase I/II, Open-Label, Multi-Center, Prospective Study to Determine the Safety and Tolerability of Sub-retinal Transplantation of Human Embryonic Stem Cell Derived Retinal Pigmented Epithelial (hESC-RPE) Cells in Patients With Stargardt's Macular Dystrophy (SMD)

The purpose of this study is to evaluate the long term safety and tolerability of hESC-RPE cellular therapy in patients with advanced SMD from 1 to 5 years following the surgical procedure to implant the hESC-RPE cells.

Read the detailed description

This study is a long-term, follow- up of a Phase I/II, open-label, non-randomized, 4-cohort, dose escalation, multi-center clinical trial (referred to as the core trial or core protocol) in which a maximum of 12 SMD patients were transplanted with sequential doses of hESC-RPE cells, starting at a dose of 50,000 hESC-RPE cells transplanted and increasing to a maximum dose of 200,000 hESC-RPE cells transplanted. All patients who participate in the core protocol are eligible for participation in the follow-up protocol. The first visit of this extension protocol will correspond to the last visit of the core protocol, and will take place at 12 months post-cell implantation. Informed consent for this follow-up protocol will be obtained at the first visit which will occur at the 12-month visit of the core protocol. Patients will be evaluated at 18, 24, 36, 48 and 60 months post-transplant (or more frequently as clinically indicated). Follow-up will include obtaining information about ophthalmological findings and events of special interest as defined in the Primary Outcome. At the last visit of this follow up study, whether at 60 months post-transplant or at early discontinuation, patients will be invited to participate in a life-long annual health survey, under a separate protocol, to further monitor long-term safety.

What is being measured

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

  1. Safety assessed by Adverse Events (AEs) of special interest in regards to the investigational product

    This will include obtaining information about Serious Adverse Events (SAEs) that are neurologic, infectious, hematologic or fatal, any Adverse Event (AE) that causes the subject to withdraw from the study, any new diagnosis of an ocular or immune-mediated disorder, cancer (irrespective of prior history), ectopic or proliferative cell growth (Retinal pigment epithelium (RPE) or non-RPE) with adverse clinical consequence, unexpected, clinically significant AE possibly related to the cell transplant procedure or the investigational product (hESC-RPE cells), Pregnancy in a female subject or the partner of a male subject and pregnancy outcome.

    Measured: 4 years

Secondary outcomes (2)
  1. Incidence of graft failure or rejection

    Evidence of graft failure or rejection may consist of: Presence of retinal edema, cystoid macular edema, retinal white dots, retinal hemorrhage, serous retinal detachment, sub-retinal exudates, sub-retinal fibrosis, ocular vascular and/or optic disc leakage, and elevated intraocular pressure or hypotony. Evidence of unanticipated and persistent or increasing non-infectious ocular inflammation (e.g., vasculitis, retinitis, choroiditis, vitritis, pars planitis, anterior segment inflammation/uveitis).

    Measured: 4 years

  2. Number of patients with changes in ocular examinations or images

    The number of patients with clinically significant absolute values or changes from baseline in Intra-ocular pressure (IOP) and Best Corrected Visual Acuity (BCVA) will be summarized.

    Measured: 4 years

Questions about this trial

What is this clinical trial studying?

An observational study of Stargardt's Macular Dystrophy, run by Astellas Institute for Regenerative Medicine at 2 sites in United Kingdom.

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 1 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 10 Dec 2020. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in United Kingdom. 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.

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?

Safety assessed by Adverse Events (AEs) of special interest in regards to the investigational product (time frame: 4 years). 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 10 Dec 2020.
