Adalimumab biosimilar (Sandoz)

The US Food and Drug Administration (FDA) has approved Sandoz ’s Enzeevu (aflibercept-abzv), the drugmaker’s biosimilar for wet age-related macular degeneration (AMD). Available as a 2mg vial kit and pre-filled syringe, the biosimilar– which references Regeneron and Bayer ’s Eylea (aflibercept) – is indicated to improve and maintain visual acuity in patients with the eye disease. Enzeevu joins Biocon Biologics’s Yesafili (aflibercept-jbvf) and Samsung Bioepis’ Opuviz (aflibercept-yszy) in the list of FDA-approved biosimilars to Eylea. Yesafili and Opuviz were both greenlit by the agency as the first biosimilars in May this year. They were both designated as interchangeable products. The FDA has provisionally said Enzeevu would be interchangeable with Eylea as “it is currently subject to an unexpired exclusivity for the first interchangeable biosimilar products”, as per a 12 August press release. Interchangeable biosimilars are eligible for a year of market exclusivity if they are the first biosimilar of a given product to receive interchangeable designation, as per the Biologics Price Competition and Innovation Act. It is possible that multiple interchangeable biosimilars could share a period of initial exclusivity if they are approved at the same time.

The company has said that Enzeevu’s launch will be dependent on the outcome of pending or potential future related litigations, as well as any potential settlements, amongst other factors. Sandoz did not reply to a request from Pharmaceutical Technology to clarify the exclusivity timelines. Biosimilars are not new to the wet AMD treatment space, with the first copycat to Genentech’s Lucentis (ranibizumab) hitting the market in 2021. Sandoz strengthened its ophthalmology portfolio when it spent $170m to acquire Cimerli (ranibizumab-eqrn) – the first interchangeable biosimilar to Lucentis – from Coherus in March this year. Sandoz stated Enzeevu will be a “key biosimilar value driver” as the company expands its ophthalmology presence. Sandoz, which completed its spin-off from Novartis late last year, lifted its 2024 sales guidance earlier this week while reporting Q2 financial results. Propelled by strong sales of the Humira-copycat Hyrimoz, the company notched total sales of $2.6bn for the second quarter. Wet AMD, also known as neovascular AMD, is a leading cause of vision loss, affecting around 1.5 million people aged 40 years and older in the US. Amongst AMD cases, the wet subtype is responsible for 90% of severe vision losses. Similar to Eylea, the biosimilars work by inhibiting vascular endothelial growth factor (VEGF), which prevents abnormal blood vessel growth. Regeneron’s Eylea currently dominates the ophthalmology market, netting $5.89bn in sales last year. However, product revenues were down by 6.3% from the year before due to increased competition from Roche’s wet AMD drug Vabysmo (faricimab) and others. Regeneron has also been locked in various court battles with other companies over alleged patent infringements with their aflibercept biosimilars. Samsung Bioepis’ Opuviz received a preliminary injunction, whilst Biocon was hit with a permanent injunction. Regeneron won a case against Viatris ’s proposed biosimilar in December 2023, citing a patent that protects its drug until 2027. Along with biosimilar introduction, Eylea will also face competition from Vabysmo. Vabysmo, whose patent expires in 2039, reached blockbuster status in only its second year on the market, notching $2.66bn in global sales last year. The biologic is predicted to see revenues of $8.5bn by 2030, according to GlobalData’s Pharma Intelligence Center. GlobalData is the parent company of Pharmaceutical Technology .

Novartis spinout Sandoz garnered $2.6 billion in second-quarter product sales. After the performance, the company raised its sales guidance for the year. After taking a market share lead in the crowded Humira biosimilar space and with other key launches in the works, Novartis spinout Sandoz is raising its full-year sales guidance.Sandoz previously communicated that it expects 2024 sales growth to reach mid-single-digit percentages. Now, after reporting second-quarter results, the company said it expects mid- to high-single-digit growth for the year.The company collected $2.6 billion in net sales during the second quarter, representing 9% sales growth compared to the same period last year.The boost was driven by the drugmaker’s clutch of biosimilars, which together saw an "exceptional" growth rate of 29%, CEO Richard Saynor said on Sandoz’s recent earnings call. Sandoz does not report individual product sales. Within the drugmaker’s biosimilar franchise, Humira copycat Hyrimoz is the standout. The med holds an 81% market share in the crowded space of biosimilar competitors to AbbVie’s popular immunology drug and has the “broadest payer coverage” of them all, according to a Sandoz investor presentation (PDF).Sandoz took on a unique strategy with its Hyrimoz, launching both a branded and an unbranded version and linking with CVS Health’s biosimilar subsidiary Cordavis on a co-labeled version. Earlier this year, CVS Caremark pulled AbbVie’s branded Humira from its national commercial formularies, in turn sending Hyrimoz prescriptions skyrocketing.Outside of Hyrimoz, the biosimilar maker has a number of potentially big launches in the works. Just recently, Sandoz launched its version of Johnson & Johnson’s Stelara in Europe. That biosim is expected to hit the U.S. in February 2025 in accordance with a J&J settlement. After that, the company looks to launch its copies of Amgen’s bone drugs Xgeva and Prolia, which will be branded as Wyost and Jubbonti, respectively, in the second quarter of next year. Regeneron and Bayer’s ophthalmology powerhouse Eylea is another potential victim of Sandoz's biosimilar ambitions. The companies are engaged in patent litigation right now, but Saynor said the company's Eylea biosimilar should arrive in the coming years.In the meantime, Sandoz can also still rely on its aging Omnitrope to buoy sales alongside Hyrimoz. That drug, a biosimilar to Pfizer’s human growth hormone Genotropin, predates even the FDA’s biosimilar approval pathway with its 2006 nod. Since then, Omnitrope has overtaken Pfizer’s original as the market leader, and its sales were still on the rise in the second quarter of 2024.It hasn’t yet been a year since Sandoz spun out of Novartis, but the company is already hard at work initiating a “multi-year transformation program” to simplify its organizational structure. Under that program, the company expects savings of $50 million in this year's second half. By 2026, Sandoz is targeting annual savings of $200 million.
