Study of Photobiomodulation to Treat Dry Age-Related Macular Degeneration (LIGHTSITE III) 96

Active, not recruiting
Clinical Trial NCT04065490 is an interventional study for Dry Age-related Macular Degeneration that is active, not recruiting. It started on 1 September 2019 with plans to enroll 96 participants. Led by LumiThera, Inc., it is expected to complete by 1 June 2022. The latest data from ClinicalTrials.gov was last updated on 5 February 2021.
Brief Summary
This LIGHTSITE III study is a double-masked, sham-controlled, parallel design, prospective multi-site study for the use of PBM as a treatment for visual impairment in subjects with dry AMD.
Detailed Description
This study is a double-masked, sham-controlled, parallel design prospective, multi-site study on the use of photobiomodulation (PBM) as a treatment for visual impairment in subjects with dry AMD. Subjects will receive repeated sham or PBM treatments at several time-points throughout the 2-year study.
Official Title

Eligibility Criteria

Eligible Ages
Adult, Older Adult
Minimum Age
50 Years
Eligible Sexes
All
  1. Male or female at least 50 years of age at Screening visit

  2. ETDRS BCVA letter score of between 50* and 75* (Snellen equivalent of 20/100 to 20/32). *If the subject meets this criterion at the Screening Visit, but the Baseline BCVA letter score is between 48 and 77, the subject may be entered in the study.

  3. Diagnosis of dry AMD as defined by the presence of the following:

    Drusen that are intermediate in size or larger (63 μm or larger in diameter) with at least a few (3) being regular drusen and not pseudodrusen and/or geographic atrophy (GA) visible on two of the following: color fundus images, OCT and/or FAF, to be confirmed by the reading center

  4. Able to communicate well with the Investigator and able to understand and comply with the requirements of the study

  5. Informed of the nature of this study and has provided written, informed consent in accordance with institutional, local and national regulatory guidelines

  1. Current or history of neovascular maculopathy that includes any of the following (to be confirmed by the reading center):

    1. Choroidal neovascularization (CNV) defined as pathologic angiogenesis originating from the choroidal vasculature that extends through a defect in Bruch's membrane
    2. Serous and/or hemorrhagic detachment of the neurosensory retina or retinal pigment epithelial (RPE)
    3. Retinal hard exudates (a secondary phenomenon resulting from chronic intravascular leakage)
    4. Subretinal and sub-RPE fibrovascular proliferation
    5. Disciform scar (subretinal fibrosis)
  2. Presence of center involving GA within the central ETDRS 1 mm diameter at Screening, to be confirmed by the reading center

  3. Media opacities, including cataracts, which might interfere with visual acuity or imaging in the study eye(s). Subjects should not be entered if there is likelihood that they will require cataract surgery in the study eye in the next 24 months.

  4. Posterior capsule opacification, which might interfere with visual acuity or imaging in the study eye(s). Subjects should not be entered if there is likelihood that they will require surgery in the study eye in the next 24 months.

  5. Invasive eye surgery (e.g. cataract, capsulotomy) on a qualifying eye within three 3 months prior to Screening

  6. Ocular disorder or disease that partially or completely obstructs the pupil (e.g. posterior synechia in uveitis)

  7. Visually significant disease in any ocular structure apart from dry AMD (e.g. diabetic macular edema, glaucoma (using >2 eye drop medications, uncontrolled IOP and/or central/paracentral visual field loss), glaucoma surgery, active uveitis, active vitreous disease, intraocular tumor, retinal vascular diseases)

  8. Ocular disorder or disease other than dry AMD that could cause drusen (glomerulonephritis Type 2, Autosomal dominant drusen), GA (North Carolina dystrophy) or mitochondrial diseases (parafoveal petaloid GA, Stargardt disease)

  9. Presence or history of disease or condition affecting functional vision without obvious structural abnormalities (e.g. amblyopia, stroke, nystagmus)

  10. Serious medical illness that will prevent the subject from performing study activities (including cardiac, hepatic, renal, respiratory, endocrinologic, neurologic, or hematologic disease) or, in the judgement of the Investigator, is likely to require surgical intervention or hospitalization at any point during the study

  11. Presence of or history of malignancy within the past 5 years other than non-melanoma skin or squamous cell cancer or cervical carcinoma in-situ

  12. Is non-ambulatory

  13. Presence or history of known light sensitivity to yellow light, red light, or near infrared radiation (NIR), or if they have a history of light activated CNS disorders (e.g. epilepsy, migraine)

  14. Use of any photosensitizing agent (e.g. topicals, injectables, oral) within 30 days of treatment without consulting subject's physician

  15. History of drug, alcohol or substance abuse within 3 months prior to Screening

  16. Has received an investigational drug or treatment with an investigational device within 3 months prior to Screening

  17. If on any anti-oxidant or vitamin Age-Related Eye Disease Study (AREDS) supplement for dry AMD, has not been stabilized for a minimum of 1 month prior to Screening. Subjects are considered to be stable if they are taking the AREDS supplements consistently as prescribed by their treating doctor.

  18. Has received Low Vision Rehab/Therapy within 30 days prior to Screening or intends to receive during the study

  19. Has an open sore(s) that may come in contact with the Valeda System, has periorbital skin erythema or is prone to such conditions with exposure to light.

  20. In the opinion of the Investigator, is unlikely to comply with the study protocol
