About this study

This study evaluates the safety and effectiveness of the Intelligent Retinal Implants System (IRIS V2). Blind patient suffering from Retinitis Pigmentosa, Cone Rod Dystrophy, or Choroideremia are implanted with an Intelligent Retinal Implant Systeme. All subjects undergo ophthalmological examinations in predefined intervals after implantation. Ophthalmological examinations include funduscopy, slit lamp examination and OCT. All adverse events are recorded and analyzed. Efficacy is measured using functional vision and visual function tests before and after implantation as well as with the system on and system off.

What is being measured

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

  1. Number of participants with treatment-related adverse events according to ISO14155

    All subjects undergo ophthalmological examinations in predefined intervals after implantation. Adverse event are rated to be serious or non-serious according ISO14155

    Measured: up to 36 month

Secondary outcomes (3)
  1. Visual acuity

    Measure probable benefit with square wave grating test

    Measured: up to 36 month

  2. Square localization

    Measure probable by measuring the error in localizing a white square on black background.

    Measured: up to 36 month

  3. Functional Vision

    Measure probable benefit e.g. by Functional Picture Assessment. The number of errors subjects make in detecting objects or persons on standardized pictures is measures. Other test may be developed during the study.

    Measured: up to 36 month

Questions about this trial

What is this clinical trial studying?

A study testing Intelligent Retinal Implant System in people with Retinitis Pigmentosa and Cone Rod Dystrophy, run by Science Corporation at 9 sites in 5 countries.

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 6 inclusion and 33 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 29 May 2019. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 9 sites in France, Germany, Austria, Spain, 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?

Number of participants with treatment-related adverse events according to ISO14155 (time frame: up to 36 month). 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 29 May 2019.
