Can you provide an overview of Regeneron’s core brands?

EYLEA® (aflibercept) Injection continues to reach more patients in competitive eye disease markets, with its efficacy, safety and convenience setting a high bar for current and potential future entries. We are confident in the durability and continued growth of this important medicine for years to come. Annual EYLEA global net product sales reached nearly US$8 billion in 2020 (net product sales outside the US recorded by our collaborator Bayer), and US$4.9 billion in the US, still without a single price increase since its launch in November 2011.

Looking to the rest of our growing portfolio, more than 80% of our top-line growth in 2020 came from products and revenues other than EYLEA. Dupixent® (dupilumab) global net product sales in 2020 (recorded by our collaborator Sanofi) were more than US$4 billion, reflecting growth of 75% versus 2019. This ‘pipeline in a product’ continues to reach more patients in need with an expanded FDA indication for atopic dermatitis in patients ages 6 to 11 and an FDA acceptance of our supplemental application as an add-on treatment for children aged 6 to 11 years with uncontrolled moderate-to-severe asthma, with even more room to grow as it meets its potential to transform the treatment of certain type 2 inflammatory diseases. We also made Dupixent treatment more convenient with the FDA approval of a single-dose, 300 mg pre-filled syringe.

As the foundation of our oncology portfolio, our PD-1 inhibitor Libtayo® (cemiplimab) is achieving significant and steady growth with recent FDA approvals in two new indications, non-small cell lung cancer and basal cell carcinoma, in early 2021. Global net product sales for Libtayo were US$348 million in 2020, representing 80% year-over-year growth.

With 11 investigational therapeutics in clinic for a wide range of cancers, including eight bispecific antibodies, we continue to diversify our approach to oncology and are positioned to lead the next wave of immuno-oncology innovation.

What factors enabled Regeneron to play such an important role in delivering COVID-19 antibody therapeutics to market?

Thanks to three decades of investment in our antibody discovery and development technologies, as well as our recent experience developing a multi-antibody cocktail for Ebola, our team was ready to quickly mobilize when COVID-19 hit. With innovative thinking and efficient, parallel track use of Regeneron’s proprietary VelociSuite technologies, the team moved an investigational antibody cocktail against SARS-CoV-2 from lab to clinic in record time. A process that would normally take years was achieved in under six months.

How does Regeneron’s antibody cocktail work against new COVID-19 variants?

REGEN-COV™ (casirivimab with imdevimab) is a cocktail of two monoclonal antibodies (also known as REGN10933 and REGN10987) and was designed specifically to block infectivity of SARS-CoV-2, the virus that causes COVID-19. The two potent, virus-neutralizing antibodies that form the cocktail bind non-competitively to the critical receptor binding domain of the virus's spike protein, which diminishes the ability of mutant viruses to escape treatment and protects against spike variants that have arisen in the human population, as detailed in Science.

How do Regeneron platform technologies drive its efficient drug discovery and development engine?

Our core capabilities for target discovery and validation are enabled by a series of Regeneron-invented technologies that accelerate, improve and disrupt the traditional drug discovery and development process. Collectively, these VelociSuite technologies represent some of the most valuable biotechnologies ever created, and aid our efforts to continuously accelerate the average timeline from discovery to drug approval — ultimately allowing us to help more patients around the world, faster.

What drives Regeneron’s scientific agenda and how does it stay true to the company’s scientific roots?

Regeneron was founded and has been led for over 30 years by physician-scientists – a rarity in the industry – and we apply this science-focused mentality to our work. We pursue therapeutic pathways based on our ability to see early promise through genetic or deep biologic research. From there, we have found that commercial success will follow.
