Algae Extract for Retinitis Pigmentosa

Retinitis Pigmentosa

Part of Eyes & vision, Genetic & congenital clinical trials.

This study tests an extract from a type of algae that is rich in a special form of vitamin A. It may help improve vision for people with retinitis pigmentosa caused by certain gene mutations that affect how the eye processes vitamin A.

Summary written for real people, not researchers, by Clin2.

Who can take part

  • You are 18 years or older
  • You have been diagnosed with retinitis pigmentosa (confirmed by an eye test called an electroretinogram)
  • You have a genetic mutation in a gene that affects the retinoid cycle (like RPE65, RDH12, or LRAT) — but not the ABCA4 gene
  • You are not currently a smoker
  • You are not taking vitamin A or beta-carotene supplements
  • You are not pregnant, breastfeeding, or planning to become pregnant without contraception

Algae powder for vision in teens with retinitis pigmentosa

This trial tests whether a powder made from a special algae can help improve vision in teenagers with retinitis pigmentosa, a genetic condition that causes vision loss. The algae contains a form of vitamin A that might protect the retina.

Study of IGT001 for retinitis pigmentosa

This trial tests an experimental drug called IGT001 for people with retinitis pigmentosa, a genetic eye disease that causes vision loss. The goal is to see if it is safe and can help slow or improve vision.

Safety study of DSP-3077 for retinitis pigmentosa

This trial tests a new medicine, DSP-3077, given as a single injection into one eye to see if it is safe for people with retinitis pigmentosa. It is for adults with advanced vision loss who have no other major eye diseases.

Minocycline for retinitis pigmentosa

This trial tests whether a common antibiotic called minocycline can slow the vision loss caused by retinitis pigmentosa. It is a randomized, double-blind study, meaning neither you nor your doctor will know if you are getting the real drug or a placebo (inactive pill). If it works, it could help preserve your remaining vision.

Stem cell eye injections for retinitis pigmentosa

This study tests whether a single injection of umbilical cord stem cells around the eye can safely help slow or improve vision loss from retinitis pigmentosa, a genetic eye disease. It also checks how long any benefits might last, using regular eye tests and a quality-of-life survey.

Gene editing treatment for retinitis pigmentosa

This study tests a gene-editing drug, ZVS203e, injected into one eye to see if it is safe and tolerable for people with retinitis pigmentosa caused by a specific genetic change in the RHO gene. It may help slow vision loss or improve vision, but the main goal is to check safety.
