Safety and Efficacy of Abicipar Pegol in Participants With Neovascular Age-related Macular Degeneration

Stable vision was defined as vision loss of fewer than 15 letters in Best-corrected Visual Acuity (BCVA) from baseline. BCVA is measured using an eye chart and is reported as the number of letters read correctly using the ETDRS Scale (ranging from 0 to 100 letters) in the study eye. The lower the number of letters read correctly on the eye chart, the worse the vision (or visual acuity). An increase in the number of letters read correctly means that vision has improved. The percentage of participants with a BCVA loss of fewer than 15 letters are reported. Study eye was defined as the eye that meets the entry criteria. If both the eyes met all of the entry criteria, the eye with worse BCVA at baseline (Day 1) was selected. If BCVA values for both eyes were identical then participant had to select the non-dominant eye, or else right eye was selected as study eye.

BCVA was measured using an eye chart and is reported as the number of letters read correctly using the ETDRS Scale (ranging from 0 to 100 letters) in the study eye. The lower the number of letters read correctly on the eye chart, the worse the vision (or visual acuity). An increase in the number of letters read correctly means that vision has improved. Mixed-effect model for repeated measures (MMRM) analysis was used. Study eye is defined as the eye that meets the entry criteria. If both the eyes met all of the entry criteria, the eye with worse BCVA at baseline (Day 1) was selected. If BCVA values for both eyes were identical then participant had to select the non-dominant eye, or else right eye was selected as study eye.

CRT was assessed using spectral domain optical coherence tomography (SD-OCT), a non-invasive diagnostic system that provides high-resolution imaging sections of the retina. SD-OCT is performed in the study eye after pupil dilation. A negative change from Baseline indicates improvement and a positive change from baseline indicates worsening. Study eye is defined as the eye that meets the entry criteria. If both the eyes met all of the entry criteria, the eye with worse BCVA at baseline (Day 1) was selected. If BCVA values for both eyes were identical then participant had to select the non-dominant eye, or else right eye was selected as study eye. MMRM analysis was used.

BCVA is measured using an eye chart and is reported as the number of letters read correctly using the Early Treatment of Diabetic Retinopathy Study (ETDRS) Scale (ranging from 0 to 100 letters) in the study eye. The lower the number of letters read correctly on the eye chart, the worse the vision (or visual acuity). An increase in the number of letters read correctly means that vision has improved. The percentage of participants with a BCVA gain of more than 15 letters are noted. Study eye is defined as the eye that meets the entry criteria. If both the eyes met all of the entry criteria, the eye with worse BCVA at baseline (Day 1) was selected. If BCVA values for both eyes were identical then participant had to select the non-dominant eye, or else right eye was selected as study eye.

NEI-VFQ-25 consists of 25 vision-targeted questions that represent 11 vision-related quality of life subscales and one general health item. Responses of individual participants were recorded as scores that ranged between 0 (worst) to 100 (best vision related function) with higher scale indicating better vision. Overall composite score is then calculated by averaging over all 11 vision-targeted subscale scores, excluding general health score. Overall composite score was calculated based on mean of non-missing subscales. Study eye: eye that meets entry criteria. If both eyes met all of entry criteria, eye with worse BCVA at baseline (day 1) was selected. If BCVA values for both eyes were identical then participant had to select non-dominant eye, or else right eye was selected as study eye. A positive change from baseline indicates improvement. MMRM analysis was used.
