REGN Regeneron brings its antibody chops to gene editing's biggest problem, aiming to 'change the field'

TARRYTOWN, NY — For over three decades, Regeneron has been synonymous with one thing in the drug industry: antibodies. Blockbusters like Dupixent, Eylea, and Covid-19 antibodies have transformed what started as a scrappy startup into one of biotech’s biggest names.
But the billionaire co-founders who still run the $91 billion giant, CEO Leonard Schleifer and CSO George Yancopoulos, have spent nearly the last decade working on the company’s next act. They have partnered, built, and bought their way into genetic medicine, going beyond antibodies into CRISPR, RNA interference, and other technologies that manipulate the genetic code of life.
It’s an audacious bet on the future of the drug industry. And even though Regeneron’s success has come from antibodies, its leaders believe new therapies may dominate its next age.
Not only is the biotech co-developing the most clinically advanced in vivo CRISPR therapy with Intellia Therapeutics and an Alzheimer’s RNA interference drug candidate with Alnylam Pharmaceuticals, it’s also quietly working on — and increasingly excited about — some earlier, less heralded research that could change the field. Its leaders believe it can crack the delivery problem that holds back the entire space. Doing so would bring genetic medicines beyond the liver to reach more parts of the body, in the process greatly expanding the medical — and commercial — possibilities of the technology.
“While everybody else was so hyped and giving Nobel Prizes for CRISPR and all that, we realized those weren’t really the limitations,” Yancopoulos, Regeneron’s chief scientific officer, told Endpoints News during an interview at the company’s Tarrytown headquarters. “The limitations were really delivery.”
Regeneron is tapping its decades-long expertise in antibodies, attaching these proteins to standard viral vectors so they hunt for specific types of cells in the body. Research is early, with no timetable on reaching the clinic, but results in mice and non-human primates have emboldened the company’s scientific leaders on the promise of the idea. If it works, Regeneron could crack the delivery challenge that has held the entire field back for years, ultimately bringing technological breakthroughs like CRISPR and RNAi to far more diseases.
“We believe we’ve become leaders in that space,” Yancopoulos said of the delivery idea. “We will hopefully be announcing programs where we’re using biologicals to deliver genetic payloads, which we think has the chance to really continue to change the field.”
There’s still a long journey ahead into making this reality. Academics first tried the idea of attaching antibodies to viral vectors in the 1990s with moderate success, but challenges in making such a complex product have deterred industry interest. Before this idea reaches the clinic, Regeneron will need to convince regulators it has the manufacturing chops to attach these antibodies to viruses in a consistent way so batches look the same. Gene therapy experts said scaling up will be a key challenge.
Still, Regeneron carries unique credibility with its deep pockets and decades of antibody experience.
“Regeneron has certainly been the leader in designing and producing specific antibodies that could be used for this purpose,” said Barry Byrne, director of the University of Florida’s gene therapy center. “They’re the ones who will probably make this work.”
Whether using a hollowed-out virus or a lipid nanoparticle, delivering genetic cargo in the body is frustratingly hard. These carriers predominantly wind up in the liver, the body’s clearinghouse organ.
While that can address diseases caused by genes expressed in liver cells, that’s not most illnesses. The brute force approach, upping doses to try to reach other organs, comes at the expense of the liver, leading to patient deaths in some gene therapy clinical studies.
“You have to give so much vector that you’re overwhelming your liver, and your liver enzymes go crazy,” said Christos Kyratsous, co-head of Regeneron’s genetic medicines team. “That becomes the major limitation for delivering the interesting payloads.”
The delivery problem has caused the field to crowd into the same liver-based targets, such as PCSK9, to slash cholesterol. Other efforts, like the sickle cell CRISPR gene-editing program now being reviewed by the FDA, avoid delivery altogether by using an ex vivo process closer to arduous transplant surgery than a typical drug.
The delivery work is one part of a sprawling genetics strategy at Regeneron, which started in 2014 with the launch of its Regeneron Genetics Center. That has become one of the world’s largest DNA-reading efforts, having sequenced 2 million genomes and counting, leading to over 10 new genetic targets tied to diseases like obesity or liver disease.
Walking around the RGC, sequencing machines tower over and outnumber white-coated scientists toiling at lab benches. It’s far more common for its 170 employees to log on remotely to check experiments or let robotic systems whiz around to handle routine tasks like pipetting.
Regeneron has inked collaborations with Decibel Therapeutics and Alnylam over the past few years, respectively working on CRISPR gene editing, gene therapy, and RNA interference to advance that RGC research. In August, Regeneron made an extraordinarily rare M&A move, agreeing to buy Decibel and its gene therapy work.
Regeneron now has six genetic medicines in its pipeline and more than 30 preclinical programs. But even as the field has generated excitement with the first US approvals for gene therapies, RNAi drugs, and mRNA vaccines all since 2017, its potential still dwarfs its current impact. The pesky delivery problem looms over the entire field.
Regeneron hopes its antibody idea can reach more organs, starting with the muscle and the brain. Preclinical data are encouraging, independent experts told Endpoints.
Regeneron’s most advanced program attaches an antibody targeting a protein found in muscle cells called CACNG1 to a viral vector. Mice and non-human primate studies showed massive boosts in reaching muscle cells, alongside big drops in entering the liver and heart compared to an unmodified version of the virus, according to data presented at this year’s American Society of Gene & Cell Therapy meeting.
“This is unlocking an entirely new space in terms of delivery and what you can actually do with all these genetic medicines,” Kyratsous said.
Christina Pacak, a University of Minnesota gene therapy researcher, called the data exciting, adding she’s hopeful for the approach.
“If we can increase safety, reduce costs, and just lower what patients are exposed to, that’s an enormous advantage,” said Pacak, who’s not involved with Regeneron’s research.
For Regeneron’s early results, other experts said they are encouraging but not industry-shaking.
“Super-beautiful data. It’s impressive,” said Nicole Paulk, CEO of the gene therapy startup Siren Biotechnology. “But it doesn’t look different magnitude-wise on either purposeful targeting or detargeting to any of the novel capsids. Competitive, but not different.”
Startups like Dyno Therapeutics, Solid Biosciences, Capsida Biotherapeutics, and Apertura Gene Therapy are all tinkering with AAVs, or adeno-associated viruses, to get beyond the liver. (Paulk sits on Dyno’s scientific advisory board.) Outside of AAVs, other startups focused on delivery include Aera Therapeutics, Ensoma, and ReCode Therapeutics.
Even as more startups take on delivery, Regeneron stands alone with its antibody idea. In a sign of its progress, its AAV-focused team has grown from the single digits about seven years ago to now several hundred people.
Outside experts repeatedly mentioned scaling up production as the key challenge to watch. Siren’s Paulk said manufacturing challenges have limited the idea’s potential for decades, as attaching antibodies can be inconsistent and finicky. Paulk said Regeneron would need to have a production trick up its sleeve to address those challenges.
“Every lot becomes a snowflake, and that becomes a challenge for the FDA,” Paulk said. “I don’t see a way this moves forward. I hope I’m dead wrong.”
David Schaffer, a bioengineering researcher at UC Berkeley, called Regeneron’s results “interesting” but noted in an email it may be “technically challenging to scale reproducibly and robustly.”
Regeneron’s leaders said they are confident in meeting that challenge. Kyratsous said they are advancing two methods of attaching antibodies to viruses, adding they’ve seen consistent results in scaling both ideas so far.
“We don’t want to over-engineer something and make something that is very cool on paper or works very well in small animal models, and you cannot scale it up for human use,” he added.
Regeneron’s leaders pointed to their experience in mass-producing antibodies and the expanding AAV team.
“We’re moving toward clinical-scale virus production,” said Leah Sabin, executive director of Regeneron’s genetic medicines unit.
Sabin said they are debating what muscle diseases to prioritize for the clinic, while a brain-targeting program is now being tested in non-human primates. The team is already mulling what tissues to target next.
“The current capsids are not good enough,” Sabin said. “They’re fine, but what would be industry-altering is having this completely new, way more efficient way to get them there.”
REGN clearly states in their filing that the competition is fierce and they are happy to steal any and all information to make a couple billion now and worry about settling in court for a few million later. They have a history of this.

TARRYTOWN, N.Y., July 20, 2021 /PRNewswire/ -- Regeneron Pharmaceuticals, Inc. (NASDAQ: REGN) today announced that Japan's Ministry of Health, Labour and Welfare (MHLW) has approved Regeneron's casirivimab and imdevimab antibody cocktail to treat patients with mild to moderate COVID-19. This marks the first time the antibody cocktail, known as REGEN-COVTM in the U.S. and Ronapreve™ in other countries, has received a full approval to treat COVID-19. Emergency or temporary pandemic use authorizations are currently in place in more than 20 countries, including in the U.S., European Union, India, Switzerland and Canada.
"After a record-speed discovery and development program, we are pleased that our COVID-19 antibody cocktail continues to reach even more people around the globe," said George D. Yancopoulos, M.D., Ph.D., President and Chief Scientific Officer of Regeneron. "Unfortunately, this virus continues to spread despite increasing rates of vaccination, and there will be an important continued need for treatments that remain active against the variants of concern."
In Japan, the antibody cocktail was granted a Special Approval Pathway under article 14-3 of the Pharmaceuticals and Medical Devices Act. The approval was based on results from a Phase 3 trial in high-risk non-hospitalized patients, which showed the antibody cocktail reduced the risk of hospitalization or death by 70%, as well as results from a Phase 1 trial that examined the safety, tolerability and pharmacokinetics in Japanese people.
Regeneron invented REGEN-COV and is collaborating with Roche to increase global supply of the antibody cocktail, with Roche primarily responsible for development and distribution outside the U.S. In December 2020, Chugai obtained development and exclusive commercialization rights in Japan from Roche, and is working with the Japanese government to ensure an appropriate and timely supply of the antibody cocktail.
The development and manufacturing of REGEN-COV have been funded in part with federal funds from the Biomedical Advanced Research and Development Authority (BARDA), part of the U.S. Department of Health and Human Services' Office of the Assistant Secretary for Preparedness and Response, under OT number: HHSO100201700020C.
About the REGEN-COV Antibody Cocktail
REGEN-COV (casirivimab and imdevimab) is a cocktail of two monoclonal antibodies that was designed specifically to block infectivity of SARS-CoV-2, the virus that causes COVID-19, using Regeneron's proprietary VelocImmune® and VelociSuite® technologies. 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.
Over the past few months Regeneron has announced results from multiple Phase 3 trials demonstrating the ability of REGEN-COV to reduce the burden of COVID-19, from prevention through to hospitalization. This includes trials assessing the ability of REGEN-COV to treat outpatients already infected with SARS-COV-2 (including symptomatic outpatients and recently infected asymptomatic patients) and in certain hospitalized patients, including the RECOVERY trial.
Multiple analyses, including a recent publication in Cell, have shown that REGEN-COV retains potency against the main variants of concern circulating within the U.S.; consequently, REGEN-COV remains available for use in all 50 states. REGEN-COV retains potency against variants including Delta (B.1.162.2; first identified in India), Gamma (P.1; first identified in Brazil), Beta (B.1.351; first identified in South Africa).
REGEN-COV is available throughout the U.S. – information on availability in your area is available from the Department of Health and Human Services and the National Infusion Center Association. REGEN-COV has not been approved by the U.S. Food and Drug Administration (FDA), but is currently authorized in the U.S. under an Emergency Use Authorization (EUA) to treat mild-to-moderate COVID-19 in adults and pediatric patients (12 years of age and older weighing ≥40 kg) with positive results of direct SARS-CoV-2 viral testing, and who are at high risk for progression to severe COVID-19, including hospitalization or death. This use is authorized only for the duration of the declaration that circumstances exist justifying the authorization of the emergency use under section 564(b)(1) of the Act, 21 U.S.C. § 360bbb-3(b)(1), unless the authorization is terminated or revoked sooner. REGEN-COV is not authorized for use in patients who are hospitalized due to COVID-19 or require oxygen therapy, or for people currently using chronic oxygen therapy because of an underlying comorbidity who require an increase in baseline oxygen flow rate due to COVID-19.
In the U.S., REGEN-COV can be administered by intravenous infusion (as short as 20 minutes) or by subcutaneous injection (4 injections), which is an alternative when intravenous infusion is not feasible and would lead to a delay in treatment. It is now authorized as a co-formulated single vial, or in individual vials to be administered together.
Regeneron and Roche share a commitment to making the antibody cocktail available to COVID-19 patients around the globe and will support access in low- and lower-middle-income countries through drug donations to be made in partnership with public health organizations.
About Regeneron's VelocImmune Technology
Regeneron's VelocImmune technology utilizes a proprietary genetically engineered mouse platform endowed with a genetically humanized immune system to produce optimized fully human antibodies. When Regeneron's President and Chief Scientific Officer George D. Yancopoulos was a graduate student with his mentor Frederick W. Alt in 1985, they were the first to envision making such a genetically humanized mouse, and Regeneron has spent decades inventing and developing VelocImmune and related VelociSuite technologies. Dr. Yancopoulos and his team have used VelocImmune technology to create approximately a quarter of all original, FDA-approved fully human monoclonal antibodies currently available. This includes REGEN-COV (casirivimab and imdevimab), Dupixent® (dupilumab), Libtayo® (cemiplimab-rwlc), Praluent® (alirocumab), Kevzara® (sarilumab), Evkeeza® (evinacumab-dgnb) and Inmazeb™ (atoltivimab, maftivimab and odesivimab-ebgn).
AUTHORIZED USE AND IMPORTANT SAFETY INFORMATION
REGEN-COV, (casirivimab and imdevimab) co-formulated product and REGEN-COV (casirivimab and imdevimab) supplied as individual vials to be administered together, is authorized for the treatment of mild to moderate coronavirus disease 2019 (COVID-19) in adults and pediatric patients (12 years of age and older weighing at least 40 kg) with positive results of direct SARS-CoV-2 viral testing, and who are at high risk for progression to severe COVID-19, including hospitalization or death. [see Limitations of Authorized Use]
REGEN-COV has not been approved, but has been authorized for emergency use by FDA
This use is authorized only for the duration of the declaration that circumstances exist justifying the authorization of the emergency use under section 564(b)(1) of the Act, 21 U.S.C. § 360bbb-3(b)(1), unless the authorization is terminated or revoked sooner
Healthcare providers should review the Fact Sheet for Healthcare Providers for information on the authorized use of REGEN-COV and mandatory requirements of the EUA and must comply with the requirements of the EUA. The FDA Letter of Authorization is available for reference, as well as the Dear Healthcare Provider Letter and Patient Fact Sheet
Limitations of Authorized Use
REGEN-COV (casirivimab and imdevimab) is not authorized for use in patients:
who are hospitalized due to COVID-19, OR

who require an increase in baseline oxygen flow rate due to COVID-19 in those on chronic oxygen therapy due to underlying non-COVID-19 related comorbidity
Benefit of treatment with REGEN-COV has not been observed in patients hospitalized due to COVID-19. Monoclonal antibodies, such as REGEN-COV, may be associated with worse clinical outcomes when administered to hospitalized patients with COVID-19 requiring high-flow oxygen or mechanical ventilation
Definition of High Risk Patients
The following medical conditions or other factors may place adults and pediatric patients (age 12-17 years and weighing at least 40 kg) at higher risk for progression to severe COVID-19:
Older age (for example, age ≥65 years of age)
Obesity or being overweight (for example, BMI >25 kg/m2, or if age 12-17, have BMI ≥85th percentile for their age and gender based on CDC growth charts, https://www.cdc.gov/growthcharts/clinical_charts.htm)
Chronic kidney disease
Immunosuppressive disease or immunosuppressive treatment
Cardiovascular disease (including congenital heart disease) or hypertension
Chronic lung diseases (for example, chronic obstructive pulmonary disease, asthma [moderate-to-severe], interstitial lung disease, cystic fibrosis and pulmonary hypertension)
Sickle cell disease
Neurodevelopmental disorders (for example, cerebral palsy) or other conditions that confer medical complexity (for example, genetic or metabolic syndromes and severe congenital anomalies)
Having a medical-related technological dependence (for example, tracheostomy, gastrostomy, or positive pressure ventilation (not related to COVID 19))
Other medical conditions or factors (for example, race or ethnicity) may also place individual patients at high risk for progression to severe COVID-19 and authorization of REGEN-COV under the EUA is not limited to the medical conditions or factors listed above.
For additional information on medical conditions and factors associated with increased risk for progression to severe COVID, see the CDC website: https://www.cdc.gov/coronavirus/2019-ncov/need-extra-precautions/people-with-medical-conditions.html. Healthcare providers should consider the benefit-risk for an individual patient.
Circulating SARS-CoV-2 viral variants may be associated with resistance to monoclonal antibodies. Healthcare providers should review the Antiviral Resistance information in Section 15 of the Fact Sheet for details regarding specific variants and resistance, and refer to the CDC website (https://www.cdc.gov/coronavirus/2019-ncov/transmission/variant-cases.html) as well as information from state and local health authorities regarding reports of viral variants of importance in their region to guide treatment decisions.
Important Safety Information
REGEN-COV (casirivimab and imdevimab) is an unapproved investigational therapy, and there are limited clinical data available. Serious and unexpected adverse events may occur that have not been previously reported with REGEN-COV use
Warnings and Precautions:
Hypersensitivity Including Anaphylaxis and Infusion-Related Reactions: Serious hypersensitivity reactions, including anaphylaxis, have been observed with administration of REGEN-COV. If signs or symptoms of a clinically significant hypersensitivity reaction or anaphylaxis occur, immediately discontinue administration and initiate appropriate medications and/or supportive therapy. Hypersensitivity reactions occurring more than 24 hours after the infusion have also been reported with the use of REGEN-COV under EUA. Infusion-related reactions, occurring during the infusion and up to 24 hours after the infusion, have been observed with administration of REGEN-COV. These reactions may be severe or life threatening
Signs and symptoms of infusion-related reactions may include: fever, difficulty breathing, reduced oxygen saturation, chills, nausea, arrythmia (e.g., atrial fibrillation, tachycardia, bradycardia), chest pain or discomfort, weakness, altered mental status, headache, bronchospasm, hypotension, hypertension, angioedema, throat irritation, rash including urticaria, pruritus, myalgia, vasovagal reactions (e.g., pre-syncope, syncope), dizziness, fatigue and diaphoresis. Consider slowing or stopping the infusion and administer appropriate medications and/or supportive care if an infusion-related reaction occurs
Clinical Worsening After REGEN-COV Administration: Clinical worsening of COVID-19 after administration of REGEN-COV has been reported and may include signs or symptoms of fever, hypoxia or increased respiratory difficulty, arrythmia (e.g., atrial fibrillation, tachycardia, bradycardia), fatigue, and altered mental status. Some of these events required hospitalization. It is not known if these events were related to REGEN-COV use or were due to progression of COVID-19
Limitations of Benefit and Potential for Risk in Patients with Severe COVID-19: Benefit of treatment with REGEN-COV has not been observed in patients hospitalized due to COVID-19. Monoclonal antibodies, such as REGEN-COV, may be associated with worse clinical outcomes when administered to hospitalized patients with COVID-19 requiring high-flow oxygen or mechanical ventilation. Therefore, REGEN-COV is not authorized for use in patients who are hospitalized due to COVID-19, OR who require oxygen therapy due to COVID-19, OR who require an increase in baseline oxygen flow rate due to COVID-19 in those on chronic oxygen therapy due to underlying non-COVID-19–related comorbidity
In a pooled phase 1/2/3 analysis of COV-2067, infusion-related reactions (adverse event assessed as causally related by the investigator) of grade 2 or higher severity have been observed in 10/4,206 (0.2%) of those who received REGEN-COV at the authorized dose or a higher dose
Overall, in Phase 1/2/3, three subjects receiving the 8,000 mg dose of REGEN-COV, and one subject receiving the 1,200 mg casirivimab and 1,200 mg imdevimab, had infusion-related reactions (urticaria, pruritus, flushing, pyrexia, shortness of breath, chest tightness, nausea, vomiting, rash) which resulted in permanent discontinuation of the infusion. All events resolved
Anaphylactic reactions have been reported in the clinical program in subjects receiving REGEN-COV. The events began within 1 hour of completion of the infusion, and in at least one case required treatment including epinephrine. The events resolved
The safety with subcutaneous administration is based on analysis from HV-2093, a randomized double-blind, placebo-controlled trial evaluating the safety and pharmacokinetic profile in healthy volunteer adult subjects. Subjects were randomized 3:1 to REGEN-COV (n=729) or placebo (n=240). Injection site reactions were observed in 12% and 4% of subjects following single dose administration in the casirivimab and imdevimab, and placebo arms respectively; the remaining safety findings with subcutaneous administration in the casirivimab and imdevimab arm were similar to the safety findings observed with intravenous administration in COV-2067
Patient Monitoring Recommendations: Clinically monitor patients during infusion and observe patients for at least 1 hour after intravenous infusion or subcutaneous dosing is complete
Use in Specific Populations:
Pregnancy: There are insufficient data to evaluate a drug-associated risk of major birth defects, miscarriage, or adverse maternal or fetal outcomes. REGEN-COV should only be used during pregnancy if the potential benefit outweighs the potential risk for the mother and the fetus
Lactation: There are no available data on the presence of casirivimab and/or imdevimab in human milk or animal milk, the effects on the breastfed infant, or the effects of the drug on milk production. The development and health benefits of breastfeeding should be considered along with the mother's clinical need for REGEN-COV and any potential adverse effects on the breastfed child from REGEN-COV or from the underlying maternal condition
