FDA approves Genentech’s Vabysmo to treat wet AMD and DME

Genentech, a member of the Roche Group has announced that the U.S. Food and Drug Administration (FDA) has approved Vabysmo (faricimab-svoa) for the treatment of wet, or neovascular, age-related macular degeneration (AMD) and diabetic macular edema (DME). Wet AMD and DME are two leading causes of vision loss among U.S. adults. Vabysmo targets and inhibits two disease pathways linked to a number of vision-threatening retinal conditions by neutralizing angiopoietin-2 (Ang-2) and vascular endothelial growth factor-A (VEGF-A). Vabysmo is said to be the first and only FDA-approved injectable eye medicine for wet AMD and DME that improves and maintains vision with treatments from one to four months apart in the first year following four initial monthly doses, based on evaluation of the patient’s anatomy and vision outcomes. Standard of care for wet AMD and DME typically requires eye injections every one to two months.

“Vabysmo represents an important step forward for ophthalmology. It is the first bispecific antibody approved for the eye and a major advance in treating retinal conditions such as wet AMD and diabetic macular edema,” said Charles Wykoff, M.D., Ph.D., Director of Research at Retina Consultants of Texas in Houston and a Vabysmo Phase III investigator. “With Vabysmo, we now have the opportunity to offer patients a medicine that could improve their vision, potentially lowering treatment burden with fewer injections over time.”

The approval is based on positive results across four Phase III studies in wet AMD and DME. The studies consistently showed that patients treated with Vabysmo given at intervals of up to four months achieved non-inferior vision gains versus aflibercept given every two months in the first year. Vabysmo was generally well tolerated in all four studies, with a favorable benefit-risk profile. The most common adverse reaction (≥5%) reported in patients receiving Vabysmo was conjunctival hemorrhage (7%). Two scientific papers and an editorial on these one-year results were recently published in ‘The Lancet’.

Vabysmo is designed to block pathways involving Ang-2 and VEGF-A. Ang-2 and VEGF-A are thought to contribute to vision loss by destabilizing blood vessels, which may cause new leaky blood vessels to form and increase inflammation. While additional research continues, inhibition of both pathways has been shown in preclinical studies to have potentially complementary benefits, stabilizing vessels and thereby reducing vessel leakage and inflammation.

“Vabysmo provides a new approach to treating vision-threatening retinal conditions through a mechanism of action that targets two pathways simultaneously,” said Levi Garraway, M.D., Ph.D., chief medical officer and head of Global Product Development. “This is our second FDA approval in ophthalmology in recent months, underscoring our commitment to people living with retinal conditions.”

With Vabysmo, people with wet AMD initially receive four monthly treatments. Based on anatomical and vision outcomes, they may receive subsequent treatments every two, three or four months. People with DME are initially given four monthly treatments. Subsequently their treatment may be extended or reduced based on anatomical and vision outcomes, with a range of one to four months between doses. A second approved treatment regimen for DME involves six monthly loading doses, followed by treatment every two months. Some people with wet AMD and DME may be treated monthly if needed, although additional efficacy was not demonstrated in most patients given Vabysmo every month.

Genentech has ongoing long-term extension studies for Vabysmo in people with wet AMD and DME. These include AVONELLE-X, an extension study of TENAYA and LUCERNE evaluating the long-term safety and tolerability of Vabysmo in wet AMD, and RHONE-X, an extension study of YOSEMITE and RHINE evaluating the long-term safety and tolerability of Vabysmo in DME. Additionally, the COMINO and BALATON trials are also underway, evaluating the efficacy and safety of Vabysmo in people with macular edema following retinal vein occlusion.

As per reports, Vabysmo will be available in the United States in the coming weeks. The European Medicines Agency is also currently evaluating the Vabysmo Marketing Authorization Application for the treatment of wet AMD and DME.
