U.S. CDC Advisory Committee unanimously recommends routine use of Beyfortus™ (nirsevimab-alip) to protect infants against RSV disease

• Recommendation for use in all infants below 8 months of age follows earlier than anticipated FDA approval and unanimous FDA Advisory Committee vote
• Committee also voted unanimously to include Beyfortus in the Vaccines for Children program, supporting equitable access for all eligible infants
• Beyfortus™ is the first RSV prevention approved to protect all infants in the U.S. through their first RSV season and will be available ahead of the 2023-2024 RSV season
  
  

Paris, August 3, 2023. The U.S. Centers for Disease Control and Prevention’s (CDC) Advisory Committee on Immunization Practices (ACIP) voted unanimously 10 to 0 to recommend routine use of Sanofi and AstraZeneca’s Beyfortus™ (nirsevimab-alip) for the prevention of respiratory syncytial virus (RSV) lower respiratory tract disease for newborns and infants below 8 months of age born during or entering their first RSV season.

The Committee also voted unanimously 10 to 0 to recommend routine use of Beyfortus for children aged 8 to 19 months who are at increased risk of severe RSV disease and entering their second RSV season.

Additionally, the ACIP voted unanimously 11 to 0 to include Beyfortus in the Vaccines for Children (VFC) program. Beyfortus will be available in the U.S. ahead of the upcoming 2023-2024 RSV season.

Thomas Triomphe
Executive Vice President, Vaccines, Sanofi
“Today, we have turned the corner on the threat of RSV to our youngest, most vulnerable population. The ACIP’s unanimous recommendations for routine use of Beyfortus and inclusion in the Vaccines for Children program are critical steps toward providing millions of parents in the U.S. with the ability to protect their babies through their first RSV season, when they are most susceptible to severe RSV disease. We appreciate the FDA and CDC leadership, as well as the ACIP public health experts, for recognizing and quickly acting on the threat RSV poses to all infants.”

Dr Regena Spratling, PhD, RN, APRN, CPNP-PC, FAANP, FAAN
President, National Association of Pediatric Nurse Practitioners
“As front-line providers managing the physical and emotional toll of RSV on our patients and their families, especially during the surges of the last two years, our community of pediatric-focused nurse practitioners welcomes the recent approval of nirsevimab. Today’s ACIP vote to include nirsevimab in routine immunization schedules, along with continued efforts to educate the public about the impact of RSV prevention, will help ensure equitable access to this immunization and help alleviate the strain RSV disease places on babies, families, and health care systems.”

The provisional ACIP recommendations will be forwarded to the director of the CDC and the U.S. Department of Health and Human Services for review and approval. The official recommendations will be published in the CDC’s Morbidity and Mortality Weekly Report (MMWR). Once approved, routine use of Beyfortus would be included in the CDC’s Child and Adolescent Immunization Schedule.        

About the U.S. ACIP and CDC recommendations
The ACIP is a body of independent health experts that advises the CDC and the nation on the types of populations and circumstances for which immunizations should be used. The CDC reviews advice from the ACIP and publishes final recommendations in the MMWR. The Affordable Care Act (ACA) generally requires coverage for all immunizations administered in accordance with final CDC recommendations. This requirement applies to all non-grandfathered commercial plans and Medicaid expansion beneficiaries. Individuals, or their healthcare providers, should contact their health insurance plan to determine coverage and reimbursement requirements as well as adoption timeframes. The Vaccines for Children (VFC) program helps provide immunizations to children whose parents or guardians may not be able to afford them. This helps ensure that all children have a better chance of getting their recommended immunizations on schedule. 

About RSV
RSV is a very contagious virus that can lead to serious respiratory illness for infants, according to the Centers for Disease Control and Prevention (CDC). RSV symptoms can include runny nose, coughing, sneezing, fever, decrease in appetite, and wheezing.¹ Two out of three infants are infected with RSV during their first year of life and almost all children are infected by their second birthday.^1,2 In the U.S., RSV is the leading cause of hospitalization in infants under 12 months, averaging 16 times higher than the annual rate for influenza.^3,4 Approximately 75% of infants hospitalized for RSV are born healthy and at term with no underlying conditions.⁵ Each year in the U.S., an estimated 590,000 RSV disease cases in infants under one require medical care, including physician office, urgent care, emergency room visits and hospitalizations.⁶

About Beyfortus
In the U.S., Beyfortus is the first RSV prevention approved to protect all infants through their first RSV season, including for those born healthy at term or preterm, or with specific health conditions that make them vulnerable to RSV disease. Beyfortus is also approved for children up to 24 months of age who remain vulnerable to severe RSV disease through their second RSV season.

As a long-acting antibody provided directly to newborns and infants as a single dose, Beyfortus offers rapid protection to help prevent lower respiratory tract disease caused by RSV without requiring activation of the immune system.⁷ Beyfortus administration can be timed to the start of the RSV season.

Beyfortus was granted Breakthrough Therapy and Fast-Track designations and was approved by the FDA on July 17, 2023 following the positive recommendation of the FDA Antimicrobial Drugs Advisory Committee. The approval was based on the extensive Beyfortus clinical development program spanning three pivotal late-stage clinical trials. Across all clinical endpoints, a single dose of Beyfortus delivered high, consistent and sustained efficacy against RSV lower respiratory tract disease extending through five months, a typical RSV season.

In March 2017, Sanofi and AstraZeneca announced an agreement to develop and commercialize Beyfortus. Under the terms of the agreement, AstraZeneca leads development and manufacturing activities and Sanofi leads commercialization activities and records revenues. Under the terms of the global agreement, Sanofi made an upfront payment of €120m, has paid development and regulatory milestones of €120m and will pay up to a further €375m upon achievement of certain regulatory and sales-related milestones. The two companies share costs and profits in all territories except in the U.S. where Sanofi consolidates 100% of the economic benefits in its Business Operating Income.

Beyfortus has been granted special designations to facilitate expedited development by several regulatory agencies around the world. These include Breakthrough Therapy Designation and Priority Review designation by The China Center for Drug Evaluation under the National Medical Products Administration; Breakthrough Therapy Designation and Fast Track Designation from the U.S. Food and Drug Administration; access granted to the European Medicines Agency (EMA) PRIority MEdicines (PRIME) scheme and EMA accelerated assessment; Promising Innovative Medicine designation by the UK Medicines and Healthcare products Regulatory Agency; and has been named “a medicine for prioritized development” under the Project for Drug Selection to Promote New Drug Development in Pediatrics by the Japan Agency for Medical Research and Development.

Beyfortus has been granted marketing authorization in the European Union, Great Britain and Canada for the prevention of RSV lower respiratory tract disease in newborns and infants from birth through their first RSV season and is currently undergoing regulatory review in China, Japan and several other countries. In Canada, nirsevimab is also approved for children up to 24 months of age who remain vulnerable to severe RSV disease through their second RSV season and such indication is under review at the EMA level.
