Two-year Phase III data presented at ASRS 2024 show Susvimo’s potential as an alternative to eye injections to treat diabetic macular edema (DME) and diabetic retinopathy (DR)
Safety data were consistent with the known safety profile for Susvimo in people with DME and DR
Additionally, the US FDA has accepted the filing application for Susvimo in DME and DR based on one-year Pagoda and Pavilion study data
Susvimo is a unique therapeutic approach that provides continuous delivery of medicine to the eye through a refillable implant
Basel, 18 July 2024 Roche (SIX: RO, ROG; OTCQX: RHHBY) announced today two-year data from the Phase III Pagoda and Pavilion studies evaluating Susvimo® (Port Delivery System with ranibizumab) for the treatment of diabetic macular edema (DME) and diabetic retinopathy (DR), respectively, the two leading causes of vision loss in adults with diabetes.1-4 Susvimo is the first and only refillable eye implant that provides continuous delivery of a customised formulation of ranibizumab via the Port Delivery Platform.5 The results build on the primary one-year analyses of the Pagoda and Pavilion studies, with Susvimo demonstrating sustained efficacy over two years and safety consistent with the known safety profile for Susvimo in people with DME and DR.6-9 Detailed results were presented at the American Society of Retina Specialists (ASRS) 2024 Annual Meeting in Stockholm, Sweden.
Additionally, the United States (US) Food and Drug Administration (FDA) has accepted Roche’s supplemental Biologics License Application (sBLA) for Susvimo for the treatment of DME and DR. The filing acceptance is based on the one-year results from the Phase III Pagoda and Pavilion studies, which showed that both studies met their primary endpoint.6,7 To date, Susvimo is approved in the US for the treatment of neovascular or ‘wet’ age-related macular degeneration (nAMD).10
“These efficacy and safety results demonstrate that Susvimo can deliver robust vision outcomes over two years for people with diabetic eye diseases that can cause vision loss,” said Levi Garraway, M.D., Ph.D., Roche’s Chief Medical Officer and Head of Global Product Development. “If approved by the US FDA, Susvimo could bring a new treatment paradigm for diabetic eye diseases. We hope to bring this option to people with diabetic macular edema and diabetic retinopathy as soon as possible to help maintain their vision and potentially their independence.”
One-year primary data supporting US sBLA in DME and DR
Treatment for DME typically involves regular eye injections every one to four months.11-13 In Pagoda, people with DME who received Susvimo refilled every six months achieved non-inferior visual acuity gains compared with those receiving monthly 0.5 mg ranibizumab intravitreal injections. Approximately 95% of patients treated with Susvimo did not need additional treatment with supplemental injections during the primary analyses study period (64 weeks). In Pavilion, people with DR who received Susvimo refilled every nine months achieved superior improvements on the Diabetic Retinopathy Severity Scale (DRSS) compared with participants under monthly clinical observation. No individuals treated with Susvimo needed additional treatment with supplemental injections during the primary analyses study period (52 weeks), compared to 60% in the control arm.
Two-year Pagoda and Pavilion results presented at ASRS
In Pagoda, people with DME receiving Susvimo refilled every six months through approximately two years (112 weeks) continued to maintain improvements in vision gains seen at one year (9.8 eye chart letters). A gain of 9.8 eye chart letters is similar to gaining two more lines on an eye chart. Approximately 95% of individuals did not need additional treatment with supplemental injections. Anatomically, Susvimo showed sustained improvements in central subfield thickness (CST) through week 112. Reduction in CST, a measure of retinal drying, is an indicator of swelling from fluid in the back of the eye caused by unstable, leaky blood vessels.14 The safety data were consistent with the known safety profile for Susvimo in people with DME, with no new safety signals observed. In people treated with Susvimo, no cases of endophthalmitis were reported up to one year and the rate of endophthalmitis through week 112 was 0.7%, compared to 0.8% in the control arm. Refills of Susvimo were resumed in affected participants after successful resolution of endophthalmitis.
In Pavilion, people with DR receiving Susvimo refilled every nine months through approximately two years (100 weeks) maintained DRSS improvements seen at one year. Specifically, at week 100, 80% of Susvimo participants achieved a two-step or greater improvement on the DRSS from pre-implant baseline, and participants who received Susvimo from week 64 either maintained or improved their DRSS score from pre-implant baseline. A two-step or greater improvement in the DRSS is a clinically relevant measure of the decrease in risk for developing vision-threatening complications secondary to diabetes.15,16 Approximately 98% of participants treated with Susvimo did not need additional treatment with supplemental injections. The safety data were consistent with the known safety profile for Susvimo in people with DR, with no new safety signals observed. In people treated with Susvimo, no cases of endophthalmitis were reported up to one year and the rate of endophthalmitis through week 100 was 0.8%. One participant with DR developed endophthalmitis and continued receiving treatment with Susvimo refills after successful resolution.

About diabetic macular edema
Affecting around 29 million people globally, diabetic macular edema (DME) is a vision-threatening retinal condition associated with blindness and decreased quality of life when left untreated.17,18 DME occurs when damaged blood vessels leak into and cause swelling in the macula – the central area of the retina responsible for the sharp vision needed for reading and driving.19,20 The number of people with DME is expected to grow as the prevalence of diabetes increases.
About diabetic retinopathy
VAccounting for approximately 5% of all cases of visual impairment, diabetic retinopathy (DR) occurs when damage to the blood vessels and the formation of new blood vessels causes blood and/or fluid to leak into the retina – a part of the eye that sends information to the brain, enabling sight.22,23 This leads to swelling, as well as blockage of the blood supply to some areas of the retina. As the condition progresses, vision becomes impaired.22,23 DR affects approximately 103 million people globally, resulting in blindness in almost five million people.
About the Pagoda study
Pagoda (NCT04108156) is a multicentre, randomised, active treatment-controlled, non-inferiority US-based Phase III study evaluating the efficacy, safety and pharmacokinetics of Susvimo® (Port Delivery System with ranibizumab) refilled every six months compared with monthly ranibizumab 0.5 mg intravitreal injections, in 634 people with diabetic macular edema. Participants were randomised 3:2 to receive either Susvimo refilled every six months or continued monthly intravitreal ranibizumab injections. In the Susvimo arm, participants received four loading doses of intravitreal ranibizumab, before Susvimo implantation at week 16. The primary endpoint of the study is a change in best-corrected visual acuity score (the best distance vision a person can achieve – including with correction such as glasses – when reading letters on an eye chart) from baseline at the average of week 60 and week 64. Following primary analyses, participants who were initially randomised to intravitreal injections received Susvimo, with refills every 24 weeks.
About the Pavilion study
Pavilion (NCT04503551) is a multicentre, randomised, US-based Phase III study evaluating the efficacy, safety and pharmacokinetics of Susvimo® (Port Delivery System with ranibizumab) 100 mg/mL refilled every nine months compared with people under monthly clinical observation, in 174 people with diabetic retinopathy without centre-involved diabetic macular edema. Participants were randomised 5:3 to receive either Susvimo with refills every nine months or monthly clinical observation, respectively. In the Susvimo arm, participants received two loading doses of intravitreal ranibizumab, before Susvimo implantation at week 4. The primary endpoint was the proportion of participants with at least a two-step improvement from baseline on the Early Treatment Diabetic Retinopathy Study-Diabetic Retinopathy Severity Scale at week 52. Following the primary analyses, participants initially in the clinical observation arm received two ranibizumab loading doses before Susvimo implantation at week 64.
About Susvimo® (Port Delivery System with ranibizumab)
Susvimo is a refillable eye implant surgically inserted into the eye during a one-time, outpatient procedure. Susvimo continuously delivers a customised formulation of ranibizumab over time.5 Ranibizumab is a vascular endothelial growth factor (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 intravitreal injection, a medicine marketed as Lucentis® (ranibizumab injection)*, which is approved to treat neovascular or ‘wet’ age-related macular degeneration (nAMD) and other retinal diseases. Lucentis* was first approved for nAMD by the United States Food and Drug Administration in 2006.
