Trial summary

The overall objective of the proposed research is to test the hypothesis that Near-infrared Light-emitting Diode (NIR-LED) therapy will stimulate mitochondrial function, attenuate oxidative stress, and improve cell survival and vision in subjects with Leber's Hereditary Optic Neuropathy (LHON).

Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 18 years and older
  • All sexes
  • Healthy volunteers accepted
  • Adult, Older adult

Who may be able to join

  • Sex - male and female. Men are affected with visual loss more frequently than women, with a male predominance of ~85%. A minimum of 25% of men and 5% of women at risk for LHON experience visual loss.
  • Age - 18 years or older. The onset of visual loss typically occurs between the ages of 15 and 35 years, but otherwise classic LHON has been reported in many individuals both younger and older, with a range of age at onset from 2 to 80 years.
  • Diagnosis of LHON or a carrier of the gene mutation. Patient must be evaluated by molecular confirmation, with the 11778 and other mutations of Leber's Hereditary Optic Neuropathy stratified in later data analysis.
  • Able \& willing to provide informed consent

Who cannot join

  • Has an optic nerve disease other than LHON.
  • Significant renal disease, defined as a history of chronic renal failure requiring dialysis or kidney transplant.
  • Participation in an investigational trial within 30 days of NIR-LED treatment that involved treatment with any drug that has not received regulatory approval at the time of study entry. (Note: subjects cannot receive another investigational drug while participating in the study during the first 6 months.)
  • Major surgery within 28 days prior to participation or major surgery planned during the next 6 months. Major surgery is defined as a surgical procedure that is more extensive than fine needle biopsy/aspiration, placement of a central venous access device, removal/biopsy of a skin lesion, or placement of a peripheral venous catheter.

About this study

The overall objective of the proposed research is to test the hypothesis that Near-infrared Light-emitting Diode (NIR-LED) therapy will stimulate mitochondrial function, attenuate oxidative stress, and improve cell survival and vision in subjects with Leber's Hereditary Optic Neuropathy (LHON).

Read the detailed description

To determine the effects of short term (3 month) near-infrared light NIR-LED therapy on anatomic and functional abnormalities of LHON as assessed by a wide variety of ophthalmologic tests, including visual acuity, optical coherence tomography, pattern electroretinography (pERG) N95 retinal ganglion cell peak, fERG-PhNR (flash ERG - Photopic Negative Response), and fundus photography.

What participants receive

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

  • Near-infrared light-emitting diode (NIR-LED) therapy (Med Light 630 PRO (Medical Devices Inc.))Device

    Also called Med Light 630 PRO (Medical Devices Inc.)

    Subjects will be exposed to light emitted from a Med Light 630 PRO (Medical Devices Inc.) at a wavelength of 630 nm (+/-15nm) with an exposure of 4 J/cm2. This is accomplished by applying the 50 mW/cm2 LED-generated light to the closed study eye for 80 seconds. Treatments involve application of the LED-generated light for 80 seconds, twice daily.

Study groups in NCT01389817
Study groupRoleWhat they receive
Symptomatic LHON patients.ExperimentalStudy Arm 1) symptomatic LHON patients. Male and female LHON patients with treatable bilateral optic atrophy. Treat the worse of the 2 eyes if there is a measurable difference in subjective visual functions (visual acuity, peripheral vision).
Receives: Device: Near-infrared light-emitting diode (NIR-LED) therapy (Med Light 630 PRO (Medical Devices Inc.))
Asymptomatic LHON mutation carriersNo interventionStudy Arm 2) asymptomatic LHON mutation carriers. Can be male or female; have some dysfunction, with changes occurring over months. Patients in study arm 2 will not be exposed to NIR-LED, but only undergo diagnostic studies.

What is being measured

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

  1. N95 Peak Via pERG and fERG -PhNR

    The primary comparison will be a paired comparison of pre- and post-treatment retinal ganglion cell N95 pattern electroretinogram (pERG) peaks and fERG - Photopic Negative Response (PhNR). Pairing will be done between a subject's treatment and control eye.

    Measured: 12 months

Timeline

From the start of the study to its completion; the mark is today. Estimated dates are the sponsor’s plan.

  1. First posted8 Jul 2011 (estimated)
  2. Study startJul 2011
  3. Primary completionMay 2013
  4. Study completionMay 2013

Why it stopped: Unable to record n95 pERG peak (primary measure), as LHON subjects are unable to focus on target.

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing Near-infrared light-emitting diode (NIR-LED) therapy (Med Light 630 PRO (Medical Devices Inc.)) in people with Leber's Hereditary Optic Neuropathy (LHON), run by Medical College of Wisconsin at 3 sites 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 4 inclusion and 4 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 29 Sep 2014. 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 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 combined 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.

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?

Yes. Results are posted in the registry (first posted 29 Sep 2014). 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?

N95 Peak Via pERG and fERG -PhNR (time frame: 12 months). 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 29 Sep 2014.
