F. Hoffmann-La Roche Ltd: New data for Roche's Vabysmo reinforce its efficacy, safety and durability in neovascular or "wet" age-related macular degeneration (nAMD)

• In AVONELLE-X, the largest long-term extension trial in nAMD, disease control and durability were maintained over 4 years, with nearly 80% of patients on extended dosing by study end¹
• Over 60% of people with a difficult-to-treat form of nAMD showed no signs of damaging lesions in the SALWEEN study, and clinically meaningful vision improvements were observed²
• Vabysmo was well tolerated with a consistent long-term safety profile in nAMD in both studies
  

Basel, 05 September 2025 - Roche (SIX: RO, ROG; OTCQX: RHHBY) announced today new data from the AVONELLE-X and SALWEEN studies of Vabysmo^® (faricimab),^1,2 presented at the 25th Euretina Congress in Paris, France. Data from the open-label AVONELLE-X study reinforce the efficacy, safety and durability of Vabysmo over four years in neovascular or "wet" age-related macular degeneration (nAMD), a leading cause of vision loss.¹ In the single-arm SALWEEN study, Vabysmo showed clinically meaningful vision gains and retinal drying over one year in polypoidal choroidal vasculopathy (PCV), a vision-threatening subtype of nAMD that is especially common in Asia.²

"The robust SALWEEN findings in PCV highlight Vabysmo's potential to deliver clinically meaningful improvements and help mitigate vision loss," said Levi Garraway, MD, PhD, Roche's chief medical officer and head of Global Product Development. "Alongside the long-term AVONELLE-X results in nAMD, these findings support our mission to develop and deliver impactful medicines for people with difficult-to-treat eye diseases."

In new one-year data from the single-arm, open-label Phase IIIb/IV SALWEEN study of Vabysmo for the treatment of people with PCV in Asia, patients experienced a clinically meaningful gain of 8.9 letters in best-corrected visual acuity (BCVA) from baseline averaged over weeks 40, 44 and 48.² At year 1, more than 50% of patients were assigned to extended five-month dosing. Vabysmo also had a clinically meaningful impact on the abnormal, polyp-like blood vessels characteristic of PCV, with these lesions completely resolving in more than 60% of patients and inactivation of polypoidal lesions in the majority (86%) of eyes.² Vabysmo was well tolerated, with a safety profile in PCV that was consistent with its known safety profile in nAMD.²

The AVONELLE-X study was a two-year open label extension of the two-year Phase III TENAYA and LUCERNE studies of Vabysmo in nAMD.¹ Vision remained stable throughout the two years of AVONELLE-X and anatomic improvement from the parent trials were sustained through AVONELLE-X.¹ Results showed that after up to four years of treatment with Vabysmo, nearly 80% of patients had extended their treatment intervals to every three or four months, reinforcing the results seen in TENAYA and LUCERNE. Vabysmo was well tolerated, and safety data were consistent with its known safety profile in nAMD.¹

To date, Vabysmo is approved in more than 100 countries for nAMD and diabetic macular edema (DME), and in more than 60 countries for macular edema following retinal vein occlusion (RVO). More than eight million doses of Vabysmo have been distributed globally since its initial US approval in 2022.^3-8

About neovascular age-related macular degeneration
Age-related macular degeneration (AMD) is a condition that affects the part of the eye that provides sharp, central vision needed for activities like reading. nAMD is an advanced form of the disease that can cause rapid and severe vision loss if left untreated.^9-11 It develops when new and abnormal blood vessels grow uncontrolled under the macula, causing swelling, bleeding and/or fibrosis.¹¹ Worldwide, around 20 million people are living with nAMD - the leading cause of vision loss in people over the age of 60 - and the condition will affect even more people around the world as the global population ages.^{9, 12-13}

About polypoidal choroidal vasculopathy
Polypoidal choroidal vasculopathy (PCV) is a subtype of nAMD that is more prevalent in people of Asian or African descent than European descent. It accounts for up to 60% of nAMD cases in people of Asian descent, and up to 20% in people of European descent.¹⁴

PCV is characterised by abnormal blood vessels in the choroid, a thin layer of tissue between the sclera (the whites of the eyes) and the retina. These abnormal vessels can leak fluid or blood, leading to retinal damage and vision loss.^14-16 People with PCV often experience blurred vision or a blind spot in or near the centre of their vision in one or both eyes.^16,17 Early diagnosis and treatment are important to help restore vision and prevent further vision loss.^15,18

About AVONELLE-X¹
AVONELLE-X (NCT04777201) was an open label multicenter two-year extension study of Vabysmo in 1,029 patients with nAMD who completed one of the two Phase III studies, TENAYA(NCT03823287) or LUCERNE (NCT03823300).

Patients in TENAYA and LUCERNE were treated with either 6 mg Vabysmo or 2 mg aflibercept. During AVONELLE-X, all patients were treated with Vabysmo on a treat-and-extend regimen, where the time between Vabysmo treatments could be adjusted based on retinal fluid levels and visual acuity.

About SALWEEN²
SALWEEN was a Phase IIIb/IV multicentre, open-label, single-arm study of Vabysmo for the treatment of Asian people with PCV. It enrolled 135 patients aged 50 years and over from 38 sites across nine markets in Asia, including China, Hong Kong SAR, India, Japan, Malaysia, Singapore, South Korea, Taiwan and Thailand. Patients received four loading doses of Vabysmo 6 mg over 12 weeks. After that, their treatment schedule was adjusted based on their progress, with doses given every eight, 12, or 16 weeks. From weeks 44 to 104, patients followed a personalised treatment plan with doses spaced out as far as every 20 weeks. The primary endpoint was the change from baseline in BCVA averaged over weeks 40-48.

About Vabysmo® (faricimab)
Vabysmo is the first bispecific antibody approved for the eye. ^3,4,19 It targets and inhibits two signalling pathways linked to a number of vision-threatening retinal conditions by neutralising angiopoietin-2 (Ang-2) and vascular endothelial growth factor-A (VEGF-A). Ang-2 and VEGF-A contribute to vision loss by destabilising blood vessels, causing new leaky blood vessels to form and increasing inflammation. By blocking pathways involving Ang-2 and VEGF-A, Vabysmo is designed to stabilise blood vessels.^19,20 Vabysmo is approved in more than 100 countries around the world, including the United States (US), Japan, the United Kingdom and the European Union (EU) for people with neovascular or 'wet' age-related macular degeneration and diabetic macular edema, and in more than 60 countries, including the US, EU and Japan, for people with macular edema following retinal vein occlusion (RVO).^3-8 Review by other health authorities is ongoing.
