A Study Of The Response to Treatment After Transition to The Port Delivery System With Ranibizumab [Susvimo (Ranibizumab Injection)] In Patients With Neovascular Age-Related Macular Degeneration Previously Treated With Intravitreal Agents Other Than Ranibizumab

A Phase IV, Multicenter, Open-Label, Single-Arm Study Of The Response to Treatment After Transition to The Port Delivery System With Ranibizumab [Susvimo (Ranibizumab Injection)] In Patients With Neovascular Age-Related Macular Degeneration Previously Treated With Intravitreal Agents Other Than Ranibizumab

Study ML43000 is a Phase IV multicenter, open-label (BCVA assessor-masked) study designed to assess the response to treatment with SUSVIMO Q24W in patients with nAMD who have been previously treated with anti-VEGF agents other than ranibizumab. The substudy will evaluate the impact on corneal endothelial cells with SUSVIMO refilled every 24 weeks (Q24W) in patients with neovascular age-related macular degeneration (nAMD).

Participants will have the implant (filled prior to implantation with approximately 20 uL of the 100-mg/mL formulation of ranibizumab [approximately 2-mg dose of ranibizumab]) surgically inserted in the study eye at the Day 1 visit following their enrollment visit. After the initial fill of the implant with ranibizumab, patients will receive implant refill-exchanges at fixed 24-week intervals.

Ranibizumab (intravitreal 0.5-mg injections of 10 mg/mL formulation) will be used in the study eye as supplemental treatment. If a study patient discontinues study treatment, he/she may start receiving intravitreal ranibizumab injections in the study eye, per investigator's discretion.

Mean change from baseline in Best Corrected Visual Acuity (BCVA) letter score at Week 40, as assessed using the Early Treatment Diabetic Retinopathy Study (ETDRS) visual acuity chart at a starting distance of 4 meters

PDS 100 mg/mL Q24W in nAMD particpants previously treated with intravitreal anti-VEGF agents other than ranibizumab

Substudy: Change in corneal endothelial cell density (ECD) from baseline at Week 48 in the study eye as compared with the fellow eye, as assessed by specular microscopy

Mean change from baseline in BCVA letter score at Week 40, as assessed using the ETDRS visual acuity chart at a starting distance of 4 meters

PDS 100 mg/mL Q24W in participants with nAMD by subgroup as defined by the last two consecutive anti-VEGF agent administered to the study eye prior to Day 1, aflibercept or bevacizumab

Percentage of participants with BCVA score of 69 letters (approximate 20/40 Snellen equivalent) or better at each scheduled visit over time to Week 52

Percentage of participants who lose < 15, < 10, < 5, or gain ≥ 0, > 0, ≥ 5, ≥ 10, or ≥15 letters in BCVA score from enrollment at each scheduled visit over time to Week 52

Annualized rate of ranibizumab treatments during the study compared with annualized rate of intravitreal anti-VEGF treatments prior to screening

Mean change in center point thickness (CPT) from baseline on spectral-domain optical coherence tomography (SD-OCT) at each scheduled visit over time to Week 52

Percentage of participants who do not require supplemental treatment with intravitreal LUCENTIS (ranibizumab injection) 0.5 mg prior to protocol-specified refill-exchanges

Percentage of participants with and without subretinal (SRF) and/or intraretinal fluid (IRF) on SD-OCT at enrollment and over study duration

The investigator will follow each adverse event until the event has resolved to baseline grade or better, the event is assessed as stable by the investigator, the patient is lost to follow-up, or the patient withdraws consent.

Change in the coefficient of variation (CV) of corneal endothelial cell area (standard deviation of the cell area/mean cell area) from baseline at Weeks 24 and 48 in the study eye as compared with the fellow eye
