Trial summary

Background: CLN3 involves vision loss observed around the preschool years, with eventual progression to blindness within 1-3 years. Researchers want to test an assistive device that may help children with CLN3 or with non-CLN3 related blindness. Read more about this study

About this study

Official title: Pilot Study of an Optic-to-Audio Device in a Pediatric Cohort With CLN3-related Conditions or Low Vision

Background:

CLN3 involves vision loss observed around the preschool years, with eventual progression to blindness within 1-3 years. Researchers want to test an assistive device that may help children with CLN3 or with non-CLN3 related blindness.

Objective:

To learn if it is safe, easy, and useful for children with CLN3 or with non-CLN3 related blindness to use the OrCam.

Eligibility:

People aged 6-18 years who have either CLN3-related disease or non-CLN3 related blindness.

Design:

Participants will be screened with the following:

Medical history

Physical exam

Family history

Eye exam and vision tests. They will get eyedrops to dilate their eyes.

Psychological and neurocognitive tests. They will be asked questions and observed for how they do various tasks, such as talking, playing, writing, drawing, and solving problems.

Hearing tests. They may wear headphones or earplugs. Electrodes may be taped to their head.

Blood samples

Skin biopsy, if needed

Cheek cell, saliva, or urine samples

The OrCam is the size of and weighs about half as much as a pack of gum. It is attached to eyeglass frames by magnets. Participants will do tasks before and after they have been trained on the OrCam. They will do these tasks without or with using the OrCam.

Participants will be given an OrCam to use for 1 week or 1 month. They will have check-in sessions with the study team.

Participants and/or their caregivers will be asked about abilities, behaviors, social skills, learning methods, intelligence, and health-related quality of life.

Participants samples may be used for genetic testing and/or to make a type of stem cell.

Participation will last for 1-5 weeks.

Read the detailed description

Study Description:

This is a pilot study of an augmentative visual device, OrCam MyEye 2 (OrCam), in pediatric individuals with CLN3-related conditions or low vision. We hypothesize that, given the relatively simple design and operating procedure of the device, the use of the OrCam by study participants will be safe and feasible. We also hypothesize that the device will enhance their ability to obtain visually based information.

Objectives:

Primary: Assess the safety and feasibility of OrCam use by children with CLN3 or low vision.

Endpoints:

Primary:

  1. Adverse events during the use of OrCam
  2. Feasibility test
  3. Feasibility questionnaire

The assessment periods will be 1 week at study site.

What participants receive

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

  • OrCam MyEye 2Device

    The OrCam MyEye 2 is a 22.5-g portable, eyeglass-mounted device that converts camera-captured inputs to auditory outputs. Its advertised functions include text reading, facial recognition, and product identification.

Study groupRoleWhat they receive
Children with CLN3 diseaseExperimentalChildren with CLN3 use the OrCam MyEye 2, a 22.5-g portable, eyeglass-mounted device that converts camera-captured inputs to auditory outputs for text reading, facial recognition, and product identification. The study participants and parents/guardians were trained on how to use the device.
Receives: Device: OrCam MyEye 2
Children with Low vision without CLN3ExperimentalChildren with low vision not related to CLN3 use the OrCam MyEye 2, a 22.5-g portable, eyeglass-mounted device that converts camera-captured inputs to auditory outputs for text reading, facial recognition, and product identification. The study participants and parents/guardians were trained on how to use the device.
Receives: Device: OrCam MyEye 2

What is being measured

Questions about this trial

What is this clinical trial studying?

A study testing OrCam MyEye 2 in people with CLN3-related Disorders and Non-CLN3 Related Low Vision, run by Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD) at 1 site in United States.

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 11 inclusion and 5 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: stopped early, as of the sponsor's last update on 23 Oct 2024. 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 United States. 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?

Yes. Results are posted in the registry (first posted 23 Oct 2024). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Participants With Adverse Events (time frame: 1 week). 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 NCT04974307, which also lists 1 linked publication.

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 23 Oct 2024.
