Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Intravitreal injections of faricimab 6mg/0.05mL will be delivered by the treating ophthalmologist at each site. Following four monthly loading doses, all patients will receive treatment under a treat-and-extend regimen until 12 months post baseline. Under the treat-and-extend regimen, the interval between treatments will be extended or reduced (determined by the treating ophthalmologist) depending on if there is disease activity present. Treatment intervals range from 4-weekly dosing to 16-weekly intervals. Treatment will be administered at each study visit. Study visits will align with treatment requirements during the treat-and-extend period. Study staff will schedule study visits with patients within a specified visit window (+-1 week). Ongoing communication between study staff and patients between study visits will ensure treatment adherence.

At each visit, a variety of ocular imaging procedures and assessments will be conducted to monitor the ocular health of the eye and assess visual function prior to treatment administration.

Eligibility
Key inclusion criteria
1. BCVA better than 20 letters as measured by an ETDRS chart (Snellen equivalent 6/120)
2. Previously treated neovascular age-related macular degeneration (nAMD), diagnosed within 36 months of the screening visit:
a. Subjects must have had at least 3 consecutive monthly injections (loading/initiation phase) of an anti-VEGF (ranibizumab or aflibercept) with a demonstrated early treatment response. An early treatment response is defined as:
i. Any reduction in retinal exudation (IRF and/or SRF) within the first 4 months of anti-VEGF treatment
b. Previous treatment with a single anti-VEGF agent (ranibizumab or aflibercept) following a treat-and-extend principle
c. First anti-VEGF injection within 36 months at screening
d. Most recent anti-VEGF injection between 1-3 months at screening
3. Active CNV, secondary to age-related macular degeneration (AMD) affecting the central subfield at screening
a. Active CNV is considered to be evidence of recurrent IRF and/or SRF affecting the central 3-mm subfield of the study eye, confirmed by confirmed by the Principal Investigator and central reading center (CRC) using spectral-domain optical coherence tomography (SD-OCT) and angiography
4. Availability of historical OCT imaging to demonstrate treatment response
5. Availability of comprehensive historical anti-VEGF injection data including anti-VEGF agent administered, total number and date of administration from the first anti-VEGF treatment for nAMD.

Key exclusion criteria
Unless specified otherwise, ocular specific exclusion criteria apply to the study eye only.

Safety/efficacy
Statistical methods / analysis
A sample size of 150 subjects was chosen to provide a 95% confidence interval margin on BCVA gain at 1 year within 5-letters.

Descriptive statistics will be used to present efficacy and safety variables (at Baseline, Weeks 4, 12, 24 and 52). Mean values + 95% confidence intervals will be used for continuous variables (e.g. BCVA, CMT, CNV lesion size, macular function, number of injections) while frequency counts and percentages (+95% confidence intervals) will be used for categorical values (e.g. fluid status, fibrosis, macular atrophy, current treatment interval, ocular and systemic AE’s). Changes in continuous endpoints will be compared using an ANCOVA model while categorical endpoints will be compared using chi-square tests.
