Time frame: Week 34
BCVA measured via the Early Treatment Diabetic Retinopathy Study (ETDRS) letter score
Time frame: Week 50 and Year 5
BCVA measured via the ETDRS letter score
Time frame: Week 34, Week 50 and Year 5
Time frame: Week 34 and Week 50
MNV measured via Fluorescein Angiography (FFA)
Time frame: Week 34 and Week 50
Leakage area assessed by FFA
Time frame: Week 34, Week 50 and Year 5
Time frame: Week 34 and Week 50
NEI VFQ-25 composite score ranges from 0 to 100. Higher scores indicate better vision-related functioning and quality of life. A positive change from baseline indicates improvement, whereas a negative change indicates worsening.
Time frame: Week 34 and Year 5
Time frame: Week 50
NAbs titer against the AAV8 capsid protein will be assessed in blood samples. Higher titers indicate a stronger neutralizing antibody response.
Time frame: Week 50
ADA titers against the nVEGF1 protein expressed by JWK001 will be measured in blood samples. Higher titers indicate a stronger anti-drug antibody response.
Time frame: Week 50
T-cell immune responses against the AAV8 capsid protein will be assessed using an enzyme-linked immunospot (ELISpot) assay.
Time frame: Week 50
T-cell immune responses against the nVEGF1 protein will be assessed using an enzyme-linked immunospot (ELISpot) assay.
Time frame: Week 4
JWK001 vector DNA will be measured in blood samples.
Time frame: Week 4
JWK001 vector DNA will be measured in tear samples
Time frame: Week 4
JWK001 vector DNA will be measured in urine samples
Time frame: Week 4
JWK001 vector DNA will be measured in fecal samples
Time frame: Week 50
The concentration of the nVEGFi transgene expression product will be measured in blood samples
Time frame: Week 104
