New Phase III Data Show Genentech’s Faricimab Is the First Investigational Injectable Eye Medicine to Extend Time Between Treatments up to Four Months in Two Leading Causes of Vision Loss, Potentially Reducing Treatment Burden for Patients
South San Francisco, CA -- February 11, 2021 -- Genentech, a member of the Roche Group (SIX: RO, ROG; OTCQX: RHHBY) today announced detailed results from four Phase III studies of its investigational bispecific antibody, faricimab, for the treatment of diabetic macular edema (DME) and neovascular or “wet” age-related macular degeneration (nAMD). The studies consistently showed that faricimab, given at intervals of up to four months, offered non-inferior vision gains compared to aflibercept, given every two months. Approximately half of people eligible for extended dosing with faricimab were able to be treated every four months in the first year in the YOSEMITE and RHINE studies in DME and the TENAYA and LUCERNE studies in nAMD. Faricimab is the first injectable eye medicine to achieve this length of time between treatments in Phase III studies for DME and nAMD. Furthermore, approximately three-quarters of people eligible for extended dosing with faricimab were able to be treated every three months or longer in the first year. Faricimab was generally well-tolerated in all four studies, with no new or unexpected safety signals identified.
Results from the studies will be presented at Angiogenesis, Exudation, and Degeneration 2021 , a medical symposium presented by Bascom Palmer Eye Institute of the University of Miami Miller School of Medicine, on Saturday, February 13.
“These faricimab data offer the promise of a new treatment for two common causes of blindness, diabetic macular edema and neovascular age-related macular degeneration," said Jeffrey Heier, M.D., Director of Retinal Research at Ophthalmic Consultants of Boston in Boston, Mass. “Faricimab’s potential to extend time between treatments may benefit those patients who struggle to keep up with the regular physician visits and eye injections needed to preserve their vision.”
While anti-vascular endothelial growth factor (VEGF) monotherapy injections have significantly reduced vision loss from DME and nAMD, the treatment burden associated with frequent eye injections and physician visits can lead to under-treatment and, potentially, less than optimal vision outcomes. Faricimab is the first investigational bispecific antibody designed for the eye. Unlike current treatments for DME and nAMD that inhibit the VEGF pathway, faricimab targets two distinct pathways – via angiopoietin-2 (Ang-2) and VEGF-A – that drive a number of retinal conditions. Through this novel mechanism of action, faricimab is designed to stabilize blood vessels and thereby reduce inflammation and leakage more than inhibiting either pathway alone. This may improve vision outcomes for longer than with anti-VEGF monotherapy, and in turn reduce the frequency of eye injections needed.
“These positive results show the potential for faricimab as the first new type of medicine in 15 years for people with neovascular age-related macular degeneration and in close to a decade in diabetic macular edema,” said Levi Garraway, M.D., Ph.D., chief medical officer and head of Global Product Development. “This is an exciting time for our ophthalmology clinical development program, with multiple Phase III successes for two medicines from our late-stage pipeline. We hope to bring these potential treatments to people living with vision-threatening retinal conditions as soon as possible.”
The YOSEMITE and RHINE studies in DME assessed two dosing regimens of faricimab given every two months or at personalized treatment intervals (PTI) of up to four months, compared to aflibercept given every two months. Patients in the PTI arm could receive treatment every one, two, three or four months, adjusted based on their disease activity. Both studies met their primary endpoint with faricimab consistently shown to offer non-inferior visual acuity gains to aflibercept. In YOSEMITE, the average vision gains from baseline were +11.6 and +10.7 eye chart letters in the faricimab PTI and two-month arms, respectively, and +10.9 letters in the aflibercept arm. In RHINE, the average vision gains from baseline were +10.8 and +11.8 letters in the faricimab PTI and two-month arms, respectively, and +10.3 letters in the aflibercept arm.
A secondary endpoint in both studies measured the proportion of people in the faricimab PTI arm that achieved dosing schedules of every three or four months at the end of the first year. Importantly, 52.8% (n=151/286) of faricimab PTI patients in YOSEMITE and 51% (n=157/308) in RHINE achieved four-month dosing at one year. An additional 21% (n=60/286) of faricimab PTI patients in YOSEMITE and 20.1% (n=62/308) in RHINE achieved three-month dosing. Combined, more than 70% of faricimab PTI patients were able to go three months or longer between treatments at the end of the first year. In both studies, faricimab given at intervals of up to four months demonstrated greater reductions in central subfield thickness (CST) compared to aflibercept given every two months.
The TENAYA and LUCERNE studies in nAMD assessed faricimab given at fixed intervals of every two, three or four months – selected based on their disease activity at weeks 20 and 24 – compared to aflibercept given every two months. Both studies met their primary endpoint, with faricimab consistently shown to offer non-inferior visual acuity gains to aflibercept. In TENAYA and LUCERNE, the average vision gains from baseline in the faricimab arms were +5.8 and +6.6 letters, respectively, compared to +5.1 and +6.6 letters in the aflibercept arms.
The studies also measured the proportion of people in the faricimab arm that were treated on dosing schedules of every three or four months during the first year. Importantly, 45.7% (n=144/315) of patients in TENAYA and 44.9% (n=142/316) in LUCERNE were able to be treated every four months in the first year. An additional 34% (n=107/315) of patients in TENAYA and 32.9% (n=104/316) in LUCERNE were able to be treated every three months. Combined, nearly 80% of faricimab-treated patients were able to go three months or longer between treatments during the first year. In both studies, faricimab given at intervals of up to four months offered reductions in CST comparable to aflibercept given every two months.
Results from all four studies will be submitted to health authorities around the world, including the U.S. Food and Drug Administration and the European Medicines Agency, for consideration of regulatory approval for the treatment of DME and nAMD.
About the YOSEMITE and RHINE Studies
YOSEMITE ( NCT03622580) and RHINE ( NCT03622593) are two identical, randomized, multicenter, double-masked, global Phase III studies, evaluating the efficacy and safety of faricimab compared to aflibercept in 1,891 people with diabetic macular edema (940 in YOSEMITE and 951 in RHINE). The studies each have three treatment arms: faricimab 6.0 mg administered at personalized dosing intervals of up to four months; faricimab 6.0 mg administered at fixed two-month intervals; aflibercept 2.0 mg administered at fixed two-month intervals. In all three arms, sham injections were administered at study visits when treatment injections were not scheduled, to maintain the masking of investigators and participants.
The primary endpoint of the studies is the average change in best-corrected visual acuity (BCVA) 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 one year. Secondary endpoints include: safety; the percentage of participants in the personalized dosing arm receiving treatment every one, two, three and four months, at week 52; the percentage of participants achieving a two-step or greater improvement from baseline in diabetic retinopathy severity at week 52; the percentage of participants achieving a gain, and the percentage avoiding a loss of 15 letters or more in BCVA from baseline over time and change in central subfield thickness from baseline over time.
About the TENAYA and LUCERNE Studies
TENAYA ( NCT03823287 ) and LUCERNE ( NCT03823300 ) are two identical, randomized, multicenter, double-masked, global Phase III studies, evaluating the efficacy and safety of faricimab compared to aflibercept in 1,329 people living with neovascular age-related macular degeneration (671 in TENAYA and 658 in LUCERNE). The studies each have two treatment arms: faricimab 6.0 mg administered at fixed intervals of every two, three, or four months, selected based on objective assessment of disease activity at weeks 20 and 24; aflibercept 2.0 mg administered at fixed two-month intervals. In both arms, sham injections were administered at study visits when treatment injections were not scheduled, to maintain the masking of investigators and participants.
The primary endpoint of the studies is the average change in best-corrected visual acuity (BCVA) score from baseline through week 48. Secondary endpoints include: safety; the percentage of participants in the faricimab arm receiving treatment every two, three and four months; the percentage of participants achieving a gain, and the percentage avoiding a loss, of 15 letters or more in BCVA from baseline over time; and change in central subfield thickness from baseline over time.
About Diabetic Macular Edema
Affecting approximately 750,000 people in the United States, diabetic macular edema (DME) is a vision-threatening complication of diabetic retinopathy (DR). DR occurs when damage to 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. This leads to swelling, as well as blockage of blood supply to some areas of the retina. DME occurs when the 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. The number of people with DME is expected to grow as the prevalence of diabetes increases. The condition is associated with blindness when left untreated and decreased quality of life. There remains a significant unmet need for more effective, longer-lasting therapies for people with DME.
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. Neovascular or “wet” AMD (nAMD) is an advanced form of the disease that can cause rapid and severe vision loss. It develops when new and abnormal blood vessels grow uncontrolled under the macula, causing swelling, bleeding and/or fibrosis. In the United States, approximately 1.1 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 in the United States as the population ages.
Faricimab is the first investigational bispecific antibody designed for the eye. It targets two distinct pathways – via angiopoietin-2 (Ang-2) and vascular endothelial growth factor-A (VEGF-A) – that drive a number of retinal conditions. Ang-2 and VEGF-A contribute to vision loss by destabilizing blood vessels, causing new leaky blood vessels to form and increasing inflammation. By simultaneously blocking both pathways involving Ang-2 and VEGF-A, faricimab is designed to stabilize blood vessels, potentially improving vision outcomes for longer for people living with retinal conditions.
