About this study

Official title: Cord Blood Platelet-rich Plasma (CB-PRP) in Retinitis Pigmentosa and Dry Age-related Macular Degeneration

The study will provides the enrollment of patients with genetic retinal dystrophies with primary rod impairment and dry age-related macular degeneration (Geographic type) A subretinal injection of umbilical cord blood platelet-rich plasma (CB-PRP) will be performed only in one eye, the other eye will be considered as a control group.

A complete morpho-functional ophthalmological evaluation will be performed in all patients at each control.

Read the detailed description

All patients underwent genetic evaluation and they reported different types of mutations that induce anatomic-functional impairment of the rods.

Patients affected by bilateral dry age-related macular degeneration (Geographic type) will be recruited as well.

After selecting the patients to be enrolled, the study will proceed with the vitrectomy surgery and subretinal injection of umbilical cord blood platelet-rich plasma (CB-PRP) provided by the Umbilical Cord Bank according to the procedures provided for by the current legislation on blood components for non-transfusion use.

A complete ophthalmological examination will be performed at 1, 3, 6, and 12 months. They will include:

  • Anterior segment biomicroscopy
  • direct and indirect ophthalmoscopy
  • ETDRS visual acuity assessment
  • intraocular pressure measurement
  • optical coherence tomography (OCT)
  • OCT Angiography (OCTA)

The following assessments will be performed at baseline and at 6 and 12 months.

  • Microperimetry
  • Electroretinogram (ERG)
  • Visually evoked potential (VEP)
  • contrast sensitivity (MARS tables)
  • Goldmann perimetry

Some morpho-functional data will also be collected in the contralateral eye and used as the control group.

To ensure the best safety for the patient, the first 5 eyes will be separated by a minimum of 20 days in order to observe the post-surgical evolution.

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Subretinal injection of umbilical cord blood platelet-rich plasma (CB-PRP) in people with Retinitis Pigmentosa and Dry Age-related Macular Degeneration, run by Fondazione Policlinico Universitario Agostino Gemelli IRCCS at 1 site in Italy.

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 7 inclusion and 3 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 11 Jan 2023. 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 Italy. 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 phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

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?

Optical coherence tomography (OCT) and optical coherence tomography angiography (OCTA) morphological changes (time frame: 3 years). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT04636853, which also lists 2 linked publications.

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 11 Jan 2023.
