Conditions

Fuchs Endothelial Corneal Dystrophy (FECD)

Brief summary

Primary Efficacy Endpoints: - Change from baseline in best corrected visual acuity (BCVA) with contrast level of 100% at Month 18 - Change from baseline in BCVA with contrast level of 10% at Month 18 - Change from baseline in contrast sensitivity with glare light at Month 18, Safety Endpoint: - Safety of DE-109D will be assessed by adverse events (AEs), slit-lamp biomicroscopy, indirect ophthalmoscopy, intraocular pressure (IOP), and laboratory tests (serum chemistry, hematology, and urinalysis).

Detailed description

Secondary Efficacy Endpoints: - Best corrected visual acuity (BCVA) with contrast level of 100% at all postbaseline visits - BCVA with contrast level of 10% at all post-baseline visits - Contrast sensitivity with glare light at all post-baseline visits - Contrast sensitivity without glare light at all post-baseline visits., - Change and percent change from baseline in BCVA with contrast level of 100% at all post-baseline visits - Change and percent change from baseline in BCVA with contrast level of 10% at all post-baseline visits - Change and percent change from baseline in contrast sensitivity with glare light at all post-baseline visits, - Change and percent change from baseline in contrast sensitivity without glare light at all post-baseline visits - Change and percent change from baseline in central corneal thickness at all post-baseline visits. - Change and percent change from baseline in endothelial cell density at all post-baseline visits., - Change and percent change in Guttae formation (Modified Krachmer scale) at all post-baseline visits
