Roche Susvimo maintains vision over five years with two refills per year in people with nAMD

Basel: Roche has announced new, five-year efficacy, safety and durability data from the Phase III Portal study, a long-term extension of the Phase III Archway study, of Susvimo (ranibizumab injection) for the treatment of people with neovascular age-related macular degeneration (nAMD).
Results show that Susvimo’s immediate and predictable durability was sustained over five years, with approximately 95% of people receiving treatment every six months requiring no supplemental treatment before each refill. The data were presented at the American Society of Retina Specialists (ASRS) 2025 Annual Meeting in Long Beach, California, United States.
“These long-term results reinforce Susvimo’s ability to maintain vision and retinal drying over a long period of time for people with nAMD, the leading cause of vision loss in people over age 60,” said Levi Garraway, MD, PhD, Roche’s chief medical officer and head of Global Product Development. “These robust data reinforce our confidence in Susvimo's unique therapeutic approach, providing an effective alternative to regular eye injections while preserving vision in a sustained manner.”
“People with nAMD often experience suboptimal outcomes with real-world anti-VEGF treatment, largely due to the frequency of injections,” said study investigator John Kitchens, M.D., Retina Associates of Kentucky, who presented the data at ASRS. “Continuous delivery of treatment with Susvimo may preserve vision in patients with nAMD for longer in real-world clinical use than IVT injections.”
In the Portal study (n = 352), people originally treated with Susvimo in Archway continued to receive Susvimo refills every six months (Susvimo cohort; n = 220), while those originally treated with monthly intravitreal (IVT) ranibizumab injections in Archway received Susvimo and then refills every six months (IVT-Susvimo cohort; n = 132).
Five-year results showed consistent and sustained disease control and retinal drying in a population who entered Archway with vision at or near peak levels after receiving an average of five intravitreal injections per standard of care. In the Susvimo cohort, best-corrected visual acuity (BCVA) was 74.4 letters at baseline and 67.6 letters at 5 years. In the IVT-Susvimo cohort, BCVA was 76.3 letters at baseline and 68.6 at 5 years. Half of all patients had better than 20/40 vision at five years (Snellen visual acuity test). Average central subfield thickness (CST) remained stable, with a 1.0 (95% CI: -13.1, 11.1) µm reduction from baseline in the Susvimo cohort, and a 10.3 (95% CI: -25.7, 5.0) µm reduction in the IVT-Susvimo cohort.
The cohort of people who entered the Portal study from Archway is the largest cohort of people with nAMD to be followed prospectively and continuously for five years in a clinical study.
Susvimo provides continuous delivery of a customised formulation of ranibizumab via the Port Delivery Platform, while other currently approved treatments may require eye injections as often as once per month. The Port Delivery Platform is a refillable eye implant surgically inserted into the eye during a one-time, outpatient procedure, which introduces medicine directly into the eye, addressing certain retinal conditions that can cause vision loss.
Approved in the United States by the Food and Drug Administration (FDA) for nAMD, diabetic macular edema (DME) and diabetic retinopathy (DR), Susvimo is a refillable eye implant surgically inserted into the eye during a one-time, outpatient procedure.8,9 Susvimo continuously delivers a customised formulation of ranibizumab over time. Ranibizumab is a VEGF inhibitor designed to bind to and inhibit VEGF-A, a protein that has been shown to play a critical role in the formation of new blood vessels and the leakiness of the vessels.
The customised formulation of ranibizumab delivered by Susvimo is different from the ranibizumab IVT injection, a medicine marketed as Lucentis (ranibizumab injection), which is approved to treat nAMD and other retinal diseases.
