About this study

Official title: Phase 1 Study To Determine the Effects of Short Term Near-infrared Light (NIR) Therapy on Anatomic and Functional Abnormalities of Diabetic Macular Edema, and Assess Safety of Short Term Near-infrared Light Therapy in Eyes With Diabetic Macular Edema.

Summary of Study Rationale Near-infrared light (NIR) via light-emitting diodes (LED) treatment promotes retinal healing and improve visual function following high intensity laser retinal injury by augmenting cellular energy metabolism, enhances mitochondrial function, increases cytochrome C oxidase activity, stimulates antioxidant protective pathways, and promotes cell survival. LED directly benefits injured neurons in the retina, the lateral geniculate nucleus, and the visual cortex, where perception occurs. From a public health perspective, a Light-Emitting Diode (LED) Array study is important to conduct because it has been approved as a non-significant risk (NSR) device for treatment of eye disorders, it has a low cost of treatment, and it may serve as an effective, non-invasive alternative or adjunctive treatment to laser photocoagulation, the current standard of care for DME.

Study Objectives and Hypotheses

To determine the effects of short term (3 month) near-infrared light (NIR) therapy on anatomic and functional abnormalities of diabetic macular edema as assessed by visual acuity, optical coherence tomography, multifocal electroretinography (mERG) and fundus bimicroscopy.
To assess safety of short term near-infrared light therapy in eyes with diabetic macular edema.

Conditions: Diabetic Macular Edema
Being tested: Warp 10 LED Device, Near-infrared light (NIR)
Keywords: Diabetic Retinopathy, Diabetic Macular Edema, NIR, Near-infrared Light Therapy
Medical subject headings: Diabetic Retinopathy

What participants receive

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

Warp 10 LED DeviceDevice
Also called Warp 10
Study Subjects will take the Warp 10 (LED) home and treat twice per day for three months
Near-infrared light (NIR)Device
Also called Warp 10 LED's
- Subjects will be exposed to light emitted from LED's at wavelengths of 670 nm (+/-15nm) with a minimum exposure of 4 J/cm2 (4.0 - 7.68J/cm2). This is accomplished by applying the 50 mW/cm2 (50 - 80 mw/cm2) LED-generated light to the study eye.
- Treatments involve application of the LED-generated light for 80 seconds, twice daily.

Study groups in NCT00846092
Study group	Role	What they receive
Device	Experimental	* The study will require 20 subjects. * Each subject will have one "study eye" that will be designated for treatment. * Subjects will be exposed to light emitted from Warp 10 LED's (Quantum Devices, Barneveld, WI) at wavelengths of 670 nm (+/-15nm) with a minimum exposure of 4 J/cm2 (4.0 - 7.68J/cm2). This is accomplished by applying the 50 mW/cm2 (50 - 80 mw/cm2) LED-generated light to the study eye. * Treatments involve application of the LED-generated light for 80 seconds, twice daily. Primary efficacy and toxicity outcomes are determined by measuring excess retinal thickness via Ocular Coherence Tomography at 1 month, 3 months, and 6 months, prior to conclusion of the study. • This protocol will be stopped if, at any point in the study, a 50% increase in excess retinal thickness is demonstrated via OCT in 25% of subjects in the experimental group. Receives: Device: Warp 10 LED Device; Device: Near-infrared light (NIR)

What is being measured

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

Excess retinal thickness on OCT at 1 month, 3 months and 6 months. goal = reduce excess thickness by at least 50%
Measured: 1 month, 3 months and 6 months

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Warp 10 LED Device and Near-infrared light (NIR) in people with Diabetic Macular Edema, run by Medical College of Wisconsin 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 7 inclusion and 7 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 23 Sep 2013. 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.

What does this phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

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?

Excess retinal thickness on OCT at 1 month, 3 months and 6 months. goal = reduce excess thickness by at least 50% (time frame: 1 month, 3 months and 6 months). 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 NCT00846092, which also lists 22 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 23 Sep 2013.
