Pfizer’s ABRYSVO™ Receives Recommendation for Use in Older Adults from Advisory Committee on Immunization Practices
- ABRYSVO recommended for adults 60 years and older to help protect against Respiratory Syncytial Virus (RSV) disease
- Pfizer presented initial data from mid- RSV season two in the Northern Hemisphere, which demonstrated ABRYSVO maintained efficacy against RSV-associated lower respiratory tract disease (LRTD)
- Additional data presented by Pfizer supports coadministration of ABRYSVO with flu vaccine in older adults
NEW YORK, June 22, 2023 – Pfizer Inc. (NYSE: PFE) announced today that the U.S. Centers for Disease Control and Prevention’s (CDC) Advisory Committee on Immunization Practices (ACIP) voted to recommend ABRYSVO™ [Respiratory Syncytial Virus (RSV) Vaccine], the company’s bivalent RSV prefusion F (RSVpreF) vaccine, for use in adults 60 years of age and older to help protect against lower respiratory tract disease caused by RSV.
Specifically, the committee voted that:
- Adults 65 years of age and older may receive a single dose of RSV vaccine, using shared clinical decision making.
- Individual adults aged 60-64 years may receive a single dose of RSV vaccine, using shared clinical decision making.
These provisional recommendations will be reviewed and finalized by the director of the CDC and the Department of Health and Human Services.
“We welcome the recommendations by ACIP as it underscores the important role ABRYSVO may have in helping to alleviate the significant burden of RSV in older adults,” said Luis Jodar, PhD, Chief Medical Affairs Officer, Vaccines/Antivirals and Evidence Generation, Pfizer. “With more than 77 million individuals aged 60 and older in the U.S., the recommended use of this vaccine can help prevent the potentially serious consequences associated with RSV, which leads to the hospitalization of more than 60,000 of these adults each year.”
The ACIP recommendations follow the U.S. Food and Drug Administration’s (FDA) approval of ABRYSVO for the prevention of lower respiratory tract disease caused by RSV in individuals 60 years of age and older.
RSV is a contagious virus and a common cause of respiratory illness worldwide.1 The virus can affect the lungs and breathing passages of an infected individual, potentially causing severe illness or death.2,3,4 In the U.S., the burden RSV causes in older adults is considerable. The severity of RSV disease can increase with age and comorbidities, such as chronic obstructive pulmonary disease, asthma, and congestive heart failure.5
MID- RSV SEASON TWO ABRYSVO EFFICACY AND FLU COADMINISTRATION DATA PRESENTED
During the meeting, Pfizer presented for the first time an analysis of initial vaccine efficacy data for mid- RSV season two in the Northern Hemisphere from the ongoing pivotal Phase 3 clinical trial (NCT05035212) RENOIR (RSV vaccine Efficacy study iN Older adults Immunized against RSV disease). Vaccine efficacy after approximately six months of disease surveillance through mid-season two was 48.9% (95.0% CI: 13.7%, 70.5%) against RSV-associated LRTD defined by two or more symptoms; and 78.6% (95.0% CI: 23.2%, 96.1%) against more severe LRTD defined by three or more symptoms. At the end of the first RSV season, as published in The New England Journal of Medicine, the vaccine demonstrated efficacy against RSV-associated LRTD defined by two or more symptoms of 65.1% (95.0%% CI: 35.9%, 82.0%); and 88.9% (95.0% CI: 53.6%, 98.7%) against more severe LRTD defined by three or more symptoms. The comparison of data show that ABRYSVO maintained efficacy between the end of season one and mid-season two.
Following administration during the trial, the vaccine was generally well-tolerated and the most common side effects (≥10%) were pain at the injection site, fatigue, headache, and muscle pain. No adverse events were reported by subjects through mid- RSV season two.
Additionally, Pfizer presented positive top-line results from the Phase 3 study evaluating the safety and immunogenicity of ABRYSVO when coadministered with seasonal inactivated influenza vaccine (SIIV) in adults 65 years and older. The results support coadministration of ABRYSVO with flu vaccine in older adults.6 Pfizer intends to publish these results in a peer-reviewed scientific journal.
ADDITIONAL PFIZER VACCINES ACIP AGENDA ITEMS
Today, ACIP will discuss additional data, including cost effectiveness, and vote on the recommendations for the appropriate use of PREVNAR 20® (20-valent Pneumococcal Conjugate Vaccine) in infants and children.
Today and on Friday, June 23, respectively, ACIP will also review additional data, including cost-effectiveness, for Pfizer’s bivalent RSV prefusion vaccine candidate, RSVpreF or PF-06928316, when administered to pregnant individuals to help protect infants from RSV disease through maternal immunization, and Pfizer’s pentavalent meningococcal vaccine candidate (MenABCWY) when administered to individuals 10 through 25 years of age.
ABOUT ABRYSVO REGULATORY REVIEW
Pfizer is currently the only company pursuing regulatory applications for an RSV investigational vaccine candidate for both an indication to help protect older adults, as well as an indication to help protect infants through maternal immunization. Previously Pfizer announced that the FDA had granted priority review for a BLA for RSVpreF for the prevention of lower respiratory tract and severe lower respiratory tract disease caused by RSV in infants from birth up to six months of age by active immunization of pregnant individuals. In May, Pfizer announced that the FDA’s Vaccines and Related Biological Products Advisory Committee voted that available data support the efficacy and safety of RSVpreF for the maternal indication. The FDA has set a Prescription Drug User Fee Act (PDUFA) action date in August 2023.
Pfizer Japan announced in May that its application with the Ministry of Health, Labor and Welfare for RSVpreF as a maternal immunization to help protect infants against RSV was accepted. In April 2023, Pfizer Canada announced Health Canada accepted RSVpreF for review for both individuals ages 60 and older and as a maternal immunization to help protect infants against RSV.
In February 2023, it was announced that the European Medicines Agency (EMA) accepted for review Pfizer’s Marketing Authorization Application (MAA) under accelerated assessment for RSVpreF, as submitted for both older adults and maternal immunization to help protect infants against RSV. The formal review process by the EMA’s Committee for Medicinal Products for Human Use (CHMP) currently is ongoing.
