About this study

Official title: A Pilot Study to Evaluate Clinical Outcomes of Photobiomodulation in Patients With Age Related Macular Degeneration of the Dry Type.

The purpose of this study is to evaluate clinical outcomes of Photobiomodulation treatment on patients with dry Age Related Macular Degeneration (AMD).

Photobiomodulation is the use of non thermal, non laser light of specific wavelengths and energy directly on the eye to improve retinal function and delay AMD progression.

This is a prospective 2 center phase 2 clinical pilot study with no placebo group.

Read the detailed description

Dry AMD is a progressive sight threatening disease affecting central acute vision. Dry AMD may progress to the wet form where leaking and bleeding in the retina can cause sudden severe visual loss.

There are no proven active treatments for Dry AMD. Dry AMD accounts for over 80% of AMD cases.

There are estimated to be 30 million people afflicted with AMD by the year 2020 in North America.

Photobiomodulation in this study is utilised by using two devices that are already approved for other indications by the FDA and Health Canada.

Photobiomodulation is a novel clinical application for treating dry AMD. As this is a pilot study there is no placebo or control group.

What participants receive

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

  • Photobiomodulation (Gentlewaves, Warp 10)Device

    Also called Gentlewaves, Warp 10

    Two separate light emitting devices that are already approved for other indications are used. Treatment will consist of 18 treatments lasting approximately two minutes per treatment.

What is being measured

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

  1. Change in ETDRS Visual Acuity

    Measured: prior to intervention and 3 monthly intervals to 1 year

Secondary outcomes (2)
  1. change in contrast sensitivity

    Measured: prior to intervention and 3 monthly to 1 year

  2. changes in retinal function parameters from Nidek MP1 assessment

    Measured: prior to intervention and 3 monthly to 1 year

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Photobiomodulation (Gentlewaves, Warp 10) in people with Nonexudative Age-related Macular Degeneration, run by Merry, Graham, M.D. at 2 sites in 2 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 4 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: finished, as of the sponsor's last update on 18 Nov 2011. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in United States, Canada. 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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?

Change in ETDRS Visual Acuity (time frame: prior to intervention and 3 monthly intervals to 1 year). 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 18 Nov 2011.
