A Clinical Effectiveness Study Examining the Efficacy and Safety of ONS-5010 in Subjects With Neovascular Age-related Macular Degeneration (AMD)

Phase 3

Completed

Conditions: Neovascular Age-related Macular Degeneration
Wet Macular Degeneration
Age-related Macular Degeneration

Brief Summary: This research study will examine the safety and effectiveness of ONS-5010 in participants with AMD. The goal is to prevent vision loss by evaluating the effectiveness of ONS-5010 as compared with ranibizumab.

- Have edema involving the fovea
- Be free of foveal scarring
- Be free of foveal atrophy

Exclusion Criteria

Previous subfoveal focal laser photocoagulation in the study eye
Laser photocoagulation (juxtafoveal or extrafoveal) in the study eye within 1-month preceding randomization
Any concurrent intraocular condition in the study eye that may require medical or surgical intervention or contribute to vision loss within 1 year
Active intraocular inflammation (grade trace or above) in the study eye
Current vitreous haemorrhage in the study eye
Polypoidal choroidal vasculopathy (PCV) confirmed by indocyanine green angiography (ICGA)

Primary Outcome Measures

Name	Time	Method
Proportion of subjects who gain 15 or more letters in the best corrected visual acuity (BCVA) score	Baseline, 11 months	BCVA to be assessed as letters read using the Early Treatment Diabetic Retinopathy Study (ETDRS) charts. A positive change represents an improvement in visual acuity.

Secondary Outcome Measures

Name	Time	Method
Proportion of participants who lose fewer than 15 letters in the best corrected visual acuity score	Baseline, 11 months	BCVA to be assessed as letters read using the ETDRS charts. A negative change represents a decrease in visual acuity.
Proportion of participants with visual-acuity Snellen equivalent of 20/200 or worse	Baseline, 11 months
Percentage of participants with ocular adverse events, non-ocular adverse events, grade 3 and above laboratory abnormalities, and vital sign abnormalities	11 months, 12 months
Proportion of participants who gain at least 5 letters in the best corrected visual acuity score	Baseline, 11 months	BCVA to be assessed as letters read using the ETDRS charts. A positive change represents an improvement in visual acuity.
Mean change in the best corrected visual acuity over time	Baseline, monthly to 11 months	BCVA to be assessed as letters read using the ETDRS charts. A positive change represents an improvement in visual acuity.
Proportion of participants who gain at least 10 letters in the best corrected visual acuity score	Baseline, 11 months	BCVA to be assessed as letters read using the ETDRS charts. A positive change represents an improvement in visual acuity.
