Stargardt Disease
Conditions
Brief summary
The primary efficacy endpoint is the annualized rate of lesion growth in the aggregate area of atrophy (definitely decreased autofluorescence [DDAF]) from baseline as assessed by FAF photography. The primary assessment of efficacy will be performed at Month 25.
Detailed description
· Annualized rate of lesion growth in total area of decreased autofluorescence (DAF; the sum of DDAF and questionably decreased autofluorescence [QDAF]) from baseline by FAF photography, · Change in photoreceptor morphology (EZ defect area) from baseline to post baseline assessments (assessed by SD-OCT), · Change in BCVA measured by the ETDRS method under standard luminance from baseline to post baseline assessments, · Change in RBP4 levels from baseline to Month 25, · Correlation between the change in RBP4 level and the change of aggregate lesion size from baseline to Month 25, Physical examination, vital signs measurement, ECG, ophthalmic examination, clinical laboratory tests (including serum chemistry and hematology panels, urinalysis, and pregnancy tests on all female subjects), retinol chemistries (plasma retinol, plasma RBP4), visual function questionnaire, measurement of intraocular pressure (IOP), dark adaptation test, dilated funduscopy, contrast sensitivity assessment of AEs, and monitoring of concomitant medications.
