View clinical trials related to Retinitis Pigmentosa (RP).
Filter by:To evaluate the natural history of visual function in subjects with IRD phenotypically diagnosed as Leber congenital amaurosis (LCA) or retinitis pigmentosa (RP) caused by RPE65 or LRAT gene mutations.
This study evaluates the safety and potential activity of a single dose of live human retinal progenitor cells (jCell) administered to adults with retinitis pigmentosa. Four different dose levels of cells will be assessed in each of two groups of patients.
The purpose of this study is: - To evaluate whether 7-day treatment with oral QLT091001 can improve visual function in RP subjects with an autosomal dominant mutation in RPE65. - To evaluate duration of visual function improvement (if observed) in RP subjects with an autosomal dominant mutation in RPE65 after 7-day treatment with oral QLT091001. - To evaluate the safety of oral QLT091001 administered once daily for 7 days in RP subjects with an autosomal dominant mutation in RPE65.
