Regeneron Pharmaceuticals


Regeneron Pharmaceuticals, Inc. is an American biotechnology company headquartered in Tarrytown, New York, according to the company's website. The company was founded in 1988. Originally focused on neurotrophic factors and their regenerative capabilities, it branched out into the study of both cytokine and tyrosine kinase receptors.

Company history

Regeneron has developed aflibercept, a VEGF inhibitor, and rilonacept, an interleukin-1 blocker. VEGF is a protein that normally stimulates the growth of blood vessels, and interleukin-1 is a protein that is normally involved in inflammation.
On March 26, 2012, Bloomberg announced that Sanofi and Regeneron are in development with a new cholesterol drug which will help reduce cholesterol up to 72% more than the leading brands. The new drug targets the PCSK9 gene.
In July 2015, the company announced a new global collaboration with Sanofi to discover, develop, and commercialise new immuno-oncology drugs, which could generate more than $2 billion for Regeneron, with $640 million upfront, $750 million for proof of concept data and $650 million from the development of REGN2810. REGN2810 was later named cemiplimab. In 2019, Regeneron Pharmaceuticals was announced the 7th best stock of the 2010s, with a total return of 1,457%.
Regeneron Pharmaceuticals was home to the two highest-paid pharmaceutical executives as of 2020.
During the COVID-19 pandemic, in early 2020, Regeneron made a deal with the US-government Biomedical Advanced Research and Development Authority that the government would fund 80% of the costs for Regeneron to develop and manufacture Coronavirus disease 2019 treatments, and Regeneron would retain the right to set prices and control production. This deal was criticized in the New York Times. Such deals are not unusual for routine drug development in the American pharmaceutical market.
In May 2020 Regeneron announced it would repurchase around $5 billion of its shares, held directly by Sanofi. Prior to the transaction Sanofi held 23.2 million Regeneron shares.

REGN-EB3 is a drug made of three antibodies, developed to treat Ebola. Among patients treated with it, 71% recovered; the mortality rate improved if the drug was administered soon after infection, at a 94% survival rate, in a timely diagnosis- critical for those infected with dangerous diseases like Ebola that can cause sepsis and, eventually, multiple organ dysfunction syndrome, more quickly than other diseases. This makes Ebola potentially a treatable disease.

Technology platforms

Trap Fusion Proteins: Regeneron's novel and patented Trap technology creates high-affinity product candidates for many types of signaling molecules, including growth factors and cytokines. The Trap technology involves fusing two distinct fully human receptor components and a fully human immunoglobulin-G constant region.
Fully Human Monoclonal Antibodies: Regeneron has developed a suite of patented technologies, including VelocImmune and VelociMab, that allow Regeneron scientists to determine the best targets for therapeutic intervention and rapidly generate high-quality, fully human antibodies drug candidates addressing these targets.
