Official title
A 24-Month, Randomized, Double-Masked, Placebo-Controlled Trial of NPI-001 for the Preservation of Photoreceptors in Retinitis PigmentosaAssociated With Usher Syndrome
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The goal of this clinical trial is to learn if NPI-001 works to prevent progression of retinitis pigmentosa in adults diagnosed with Usher syndrome. It will also provide information about the safety of NPI-001. The main questions it aims to answer are: Does NPI-001 slow down the loss of photoreceptors? What medical problems do participants have when taking NPI-001? Researchers will compare NPI-001 to a placebo (a look-alike substance that contains no drug) to see if NPI-001 works to preserve vision. Participants will: Take NPI-001 or a placebo twice a day, every day for 24 months and visit the clinic 9 times for checkups and tests.
