NEW YORK--(BUSINESS WIRE)--Pfizer Inc. (NYSE:PFE) today announced that the U.S. Food and Drug Administration (FDA) accepted for priority review a Biologics License Application (BLA) for its 20-valent pneumococcal conjugate vaccine (20vPnC) candidate, as submitted for the prevention of invasive disease and pneumonia caused by Streptococcus pneumoniae serotypes in the vaccine in adults ages 18 years and older.
The Prescription Drug User Fee Act (PDUFA) goal date for a decision by the FDA on the 20vPnC application is in June 2021.
“The FDA’s acceptance of our application for 20vPnC is yet another significant milestone in Pfizer’s continuing efforts to help protect adults against pneumococcal disease,” said Kathrin U. Jansen, Ph.D., Senior Vice President and Head of Vaccine Research and Development, Pfizer. “If approved, 20vPnC will cover more serotypes responsible for the majority of pneumococcal disease than any other pneumococcal conjugate vaccine currently licensed or currently in late-stage clinical development. Importantly, 20vPnC has shown to induce immune memory, which provides protection and efficacy against non-bacteremic pneumonia, particularly in older adults.”
Pfizer’s 20vPnC vaccine candidate includes capsular polysaccharide conjugates for the 13 serotypes already included in Prevnar 13® (Pneumococcal 13-valent Conjugate Vaccine[Diphtheria CRM197 Protein]). The vaccine also contains capsular polysaccharide conjugates for seven additional serotypes that cause invasive pneumococcal disease (IPD),1,2,3,4,5 and have been associated with high case-fatality rates,6,7,8,9 antibiotic resistance,4,10,11 and/or meningitis.12,13 Globally, pneumococcal pneumonia is estimated to cause about 500,000 deaths and 30 million episodes in adults 70 years and older annually. Together, the 20 serotypes included in 20vPnC are responsible for the majority of currently circulating pneumococcal disease in the U.S. and globally.14,15,16,17,18,19,20
The 20vPnC regulatory submission encompasses data from Pfizer’s clinical program in adults, which includes Phase 1 and 2 trials and three Phase 3 trials (NCT03760146, NCT03828617, and NCT03835975) describing the safety and evaluating the immunogenicity of the vaccine candidate to support licensure for an indication to prevent invasive disease and pneumococcal pneumonia caused by Streptococcus pneumoniae serotypes in the vaccine in adults 18 years or older. The three Phase 3 trials have enrolled more than 6,000 adult subjects, 18 years and older, including adults 65 years of age and above, and populations of vaccine-naïve adults and adults with prior pneumococcal vaccination.21,22
On September 20, 2018, Pfizer announced the U.S. Food and Drug Administration (FDA) granted Breakthrough Therapy Designation for 20vPnC for the prevention of invasive disease and pneumonia caused by Streptococcus pneumoniae serotypes in the vaccine candidate in adults age 18 years or older. Breakthrough Therapy Designation is designed to expedite the development and review of drugs and vaccines that are intended to treat or prevent serious conditions and preliminary clinical evidence indicates that the drug or vaccine may demonstrate substantial improvement over available therapy on a clinically significant endpoint(s).23 Drugs and vaccines that receive Breakthrough Therapy Designation are eligible for all features of the FDA’s Fast Track designation, which may include more frequent communication with the FDA about the drug’s development plan and eligibility for Accelerated Approval and Priority Review, if relevant criteria are met.24
The FDA previously granted Fast Track designation for 20vPnC in September 2017 for use in adults aged 18 years or older.25 The FDA’s Fast Track approach is a process designed to facilitate the development and expedite the review of new drugs and vaccines intended to treat or prevent serious conditions and address an unmet medical need.25
Additionally, in May 2017 the FDA granted Fast Track status and in August 2020 Breakthrough Therapy Designation for a pediatric indication for 20vPnC.26
INDICATIONS FOR PREVNAR 13®
- Prevnar 13® is a vaccine approved for adults 18 years and older for the prevention of pneumococcal pneumonia and invasive disease caused by S. pneumoniae serotypes 1, 3, 4, 5, 6A, 6B, 7F, 9V, 14, 18C, 19A, 19F, and 23F
- Prevnar 13® is also approved for children 6 weeks through 17 years of age (prior to the 18th birthday) for the prevention of invasive disease caused by the 13 strains of Streptococcus pneumoniae in the vaccine, and for children 6 weeks through 5 years (prior to the 6th birthday) for the prevention of ear infections caused by 7 of the 13 strains in the vaccine
- Prevnar 13® is not 100% effective and will only help protect against the 13 strains in the vaccine
IMPORTANT SAFETY INFORMATION
- Prevnar 13® should not be given to anyone with a history of severe allergic reaction to any component of Prevnar 13® or any diphtheria toxoid–containing vaccine
- Children and adults with weakened immune systems (eg, HIV infection, leukemia) may have a reduced immune response
- In adults, the most common side effects were pain, redness, and swelling at the injection site, limitation of arm movement, fatigue, headache, muscle pain, joint pain, decreased appetite, vomiting, fever, chills, and rash
- A temporary pause of breathing following vaccination has been observed in some infants born prematurely
- The most commonly reported serious adverse events in infants and toddlers were bronchiolitis (an infection of the lungs) (0.9%), gastroenteritis (inflammation of the stomach and small intestine) (0.9%), and pneumonia (0.9%)
- In children 6 weeks through 17 years, the most common side effects were tenderness, redness, or swelling at the injection site, irritability, decreased appetite, decreased or increased sleep, and fever
- Ask your healthcare provider about the risks and benefits of Prevnar 13®. Only a healthcare provider can decide if Prevnar 13® is right for you or your child
