About this study

Official title: Pivotal Trial to Assess the Clinical Performance of Ophthal-360

Multicenter, prospective, study to assess the performance of the Ophthal-360 platform in the diagnosis of more-than-mild Diabetic Retinopathy (mtmDR) in diabetic patients with no previous diagnosis of DR.

Read the detailed description

This is a multicenter, prospective study in which 500 adult subjects at risk for DR but never before diagnosed who satisfy all entry criteria will be enrolled at up to 5 primary care sites.

An additional sub-study will be performed on 30 subjects to assess the precision of the algorithm in detecting DR by imaging these subjects multiple times to demonstrate intra- and inter-operator reliability of the algorithm.

All enrolled subjects will undergo retinal imaging by a novice operator with no experience using the fundus cameras listed. Images from each retinal imaging device will be saved to a computer and uploaded to the server for evaluation by the Ophthal-360 service. A report will be generated and archived for the results of each image.

After imaging by the novice operator, each patient will then have their eyes photographed by a professional fundus photographer using standard mydriatic and OCT imaging for macular edema evaluation. These images will be sent to a Fundus Photography Reading Center for final determination and diagnosis. Patients will received the result of the FPRC evaluation, but not be provided the reports generated by the software.

A comparison between the FPRC determination and the software generated report will be performed to evaluate the analytical performance of the algorithm.

What is being measured

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

    Measured: 1 day

  2. Specificity of the Ophthal-360 Software to detect diabetic retinopathy in fundus images

    Performance of the Ophthal-360 Software when compared to ground truth evaluation of fundus photographs by qualified experts.

    Measured: 1 day

Questions about this trial

What is this clinical trial studying?

An observational study of Diabetic Retinopathy, run by Ophthalytics, Inc..

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 9 inclusion and 10 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: status not confirmed, as of the sponsor's last update on 10 Apr 2023. Status can change between updates, so confirm with the study contact before making plans.

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?

Results are not available in the source record.

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

Contact Joshua Freeman (617 320 4668, josh@ophthalytics.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Sensitivity of the Ophthal-360 Software to detect diabetic retinopathy in fundus images (time frame: 1 day). The study lists 2 primary outcomes in all. 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 Apr 2023.
