Study population: Patients with T1DM and T2DM under clinical setting. Invitation to volunteer

Who may be able to join

  • Subject must understand the study, has chosen to participate voluntarily, and has signed informed consent
  • Age 18 or older, no limitations on gender identity

Who cannot join

  • As it is difficult to obtain fundus images of satisfactory quality with small pupils, mydriasis is advisable under certain circumstances except if:

  • the subject's intraocular pressure (IOP) ≥ 22 mmHg;
  • the subject is prone to post-dilation angle closure, pupillary block, etc.;

About this study

Official title: A Prospective, Multi-center Clinical Study on the Application of An Artificial Intelligence Enabled Disease Detection Software to Diabetic Retinopathy Screening Based on Fundus Images

Early detection and intervention of diabetic retinopathy (DR) is critical in preventing DR-related vision loss among type 1 (T1DM) and type 2 diabetic mellitus (T2DM) patients, currently estimated at over 100 million in China alone. Yet the healthcare resources, particularly retinal specialists, are in short supply and unevenly distributed. In order to help address this enormous mismatch and implement population-based screening, an artificial intelligence (AI) enabled, cloud based software is developed by training a custom-built convolutional neural network.

This study is designed to evaluate the safety and efficacy of such device in detecting referable diabetic retinopathy (moderate non-proliferative DR or worse).

Read the detailed description

This prospective, multi-center clinical study is designed to validate the performance of an AI enabled software - Shenzhen SiBright AIDRScreening - in detecting referable diabetic retinopathy (RDR, defined as more than mild NPDR) among study subjects primarily by evaluating its sensitivity and specificity.

The subjects enrolled in this trial are patients with T1DM and T2DM. For those who qualify, color fundus images of each eyes are taken and then independently graded for RDR by both the device under test and a centralized reading center, which, for the purpose of this trial, is the Image Reading Center at Zhongshan Ophthalmic Center, Sun Yat-sen University (ZIRC). The grading from ZIRC serves as the gold standard to compare the device performance against.

The trial plans to enroll 1000 subjects. With a 95% confidence interval, the sensitivity is expected to be at least 85% whereas the specificity at 90% or above.

Fundus image quality assessment is performed according to the National DR Screening Imaging and Grading Guideline jointly published by Chinese Ophthalmological Society and Chinese Medical Doctor Association in 2017.

The diagnosis of RDR is based on the National DR Clinical Diagnosis and Treatment Guideline published by Chinese Ophthalmological Society in 2014.

A brief overview of the clinical protocol is as follows:

  1. Candidate screening phase: recruiting qualified trial subjects;
  2. Clinical phase: imaging and grading by AI and ZIRC;
  3. Statistical analysis phase: comparing two outputs;
  4. Closing phase: final report and archiving

What participants receive

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

  • AI-enabled Diabetic Retinopathy Screening SoftwareDevice

    Color fundus images of both eyes are captured on site before being uploaded to and analyzed by the cloud-based Artificial Intelligence software

What is being measured

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

  1. Sensitivity and specificity

    To evaluate the sensitivity and specificity of the device in detecting referable DR (more than mild NPDR)

    Measured: No more than 1 day for each subject

Questions about this trial

What is this clinical trial studying?

An observational study of Diabetic Retinopathy, run by Shenzhen SiBright Co., Ltd. at 3 sites in China.

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 3 inclusion and 12 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 20 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 3 sites in China. 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?

Results are not available in the source record.

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?

Sensitivity and specificity (time frame: No more than 1 day for each subject). 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 20 May 2019.
