Pfizer and BioNTech Announce Positive Early Data From Clinical Trial of Omicron BA.4/BA.5-Adapted Bivalent Booster in Individuals 18 Years and Older

  • Sera collected from participants 7 days after administration of a 30-µg booster dose of the Omicron BA.4/BA.5-adapted bivalent COVID-19 vaccine showed a substantial increase in the Omicron BA.4/BA.5 neutralizing antibody response above pre-booster levels
  • Data suggest Omicron BA.4/BA.5-adapted bivalent booster is anticipated to provide better protection against Omicron BA.4/BA.5 sublineages than original vaccine across younger and older adults
  • Omicron BA.4/BA.5-adapted bivalent vaccine was well tolerated with early data showing a safety profile similar to that of the original vaccine
  • Additional data measuring responses at 1-month post-administration of the Omicron BA.4/BA.5-adapted bivalent vaccine booster are expected in the coming weeks

PfizerInc.( NYSE PFE) and BioNTech SE( Nasdaq BNTX) moment blazoned early data from a Phase2/3 clinical trial( NCT05472038) assessing the safety, tolerability, and immunogenicity of the companies ’ OmicronBA.4/BA.5- acclimated bivalent COVID- 19 vaccine( Pfizer- BioNTech COVID- 19 Vaccine, Bivalent( Original and OmicronBA.4/BA.5)).
A 30- µg supporter cure of the OmicronBA.4/BA.5- acclimated bivalent vaccine demonstrated a substantial increase in the OmicronBA.4/BA.5 negativing antibody response abovepre-booster situations grounded on sera taken 7 days after administration, with analogous responses seen across individualities progressed 18 to 55 times of age and those aged than 55 times of age( 40 actors in each age group). When comparing responses in individualities aged than 55 times of age who entered either the bivalent vaccine, or the original vaccine, a 30- µg supporter cure of the Original Pfizer- BioNTech COVID- 19 Vaccine( also appertained to as BNT162b2 Wild Type) inspired more limited increases in the negativing antibody response against the OmicronBA.4/BA.5 variants. COVID- 19 vaccine responses to date have reliably shown harmonious trends across age groups and are further supported by these early data on the bivalent vaccine. Together, these data suggest a 30- µg supporter cure of the OmicronBA.4/BA.5- acclimated bivalent vaccine is anticipated to give better protection against the OmicronBA.4 andBA.5 variants than the original vaccine for youngish and aged grown-ups. The OmicronBA.4 andBA.5- acclimated bivalent vaccine was well permitted with early data indicating a favorable safety profile, analogous to that of the original vaccine.

“ Since the foremost days of the epidemic, we’ve strived to transparently share data regarding our COVID- 19 vaccines in the interest of public health, ” said Albert Bourla, Chairman and Chief Executive Officer, Pfizer. “ While we anticipate more mature vulnerable response data from the clinical trial of our OmicronBA.4/BA.5- acclimated bivalent vaccine in the coming weeks, we’re pleased to see encouraging responses just one week after vaccination in youngish and aged grown-ups. These early data suggest that our bivalent vaccine is anticipated to give better protection against presently circulating variants than the original vaccine and potentially help to check unborn surges in cases this downtime. ”

“ These primary findings are harmonious with our preclinical data showing a substantial increase in the negativing antibody response against the Omicron sublineagesBA.4 andBA.5, ” saidProf. Ugur Sahin,M.D., CEO andCo-founder of BioNTech. “ The current dominance ofBA.4/BA.5 and related sublineages, underscores the significance of our data and wisdom- grounded approach to develop a vaccine which is acclimated to these current strains of the contagion and make it available in a timely manner. ”

The Pfizer- BioNTech COVID- 19 Vaccines( COMIRNATY ®), which are grounded on BioNTech’s personal mRNA technology, were developed by both BioNTech and Pfizer. BioNTech is the Marketing Authorization Holder for BNT162b2 Wild Type and BNT162b2 Bivalent( WT/ OMIBA.4/BA.5) in the United States, the European Union, the United Kingdom, Canada and other countries, and the holder of exigency use authorizations or coequals in the United States( concertedly with Pfizer) and other countries. cessions to pursue nonsupervisory blessings in those countries where exigency use authorizations or original were originally granted are planned.

About the Phase2/3 Study

This multicenter, randomized, controlled Phase2/3 trial( NCT05472038) has enrolled about 900 healthy levies 12 times of age and aged in theU.S. who have entered at least three boluses of an authorized COVID- 19 vaccine. During the trial, actors progressed 18 and aged entered either a 30- µg or 60- µg supporter cure of Pfizer and BioNTech’s OmicronBA.4/BA.5- acclimated COVID- 19 vaccine and actors aged 12 through 17 times entered a 30- µg supporter of the same vaccine. Comparisons to support implicit full licensure and enrollments encyclopedically will be made with a control group who preliminarily entered a fourth cure with the original vaccine.
