Clinical Trials

On this page you can find a list of clinical trials for inherited retinal diseases, such as retinitis pigmentosa and Stargardt disease, as well as for some innovative treatments for age-related macular degeneration (AMD) and diabetes-related eye conditions.

Where available, the following information is included for each trial:

  • Type of treatment, such as gene therapy, stem cell therapy or a drug
  • Gene and mutation, or cell type
  • Drug name (alternative or brand name in brackets)
  • Trial sponsor and phase (TRIAL NAME capitalized in brackets)
  • Other information including if there is a Canadian trial site, or links to completed trial results or updates
  • number. This will link out to trial page on the website

You can find more information about these or other clinical trials at This website can be a good place to start your research. However, trials listed have not always been approved by the FDA and may not meet basic safety standards. Always consult your doctor before participating in any trial.
