Pfizer and BioNTech Announce Submission of Initial Data to U.S. FDA to Support Booster Dose of COVID-19 Vaccine

Pfizer | August 17, 2021

Pfizer Inc. and BioNTech SE today announced that they have submitted Phase 1 data to the U.S. Food and Drug Administration (FDA) to support the evaluation of a third, or booster, dose of the companies’ COVID-19 vaccine (BNT162b2) for future licensure. These data also will be submitted to the European Medicines Agency (EMA) and other regulatory authorities in the coming weeks.

“The data we’ve seen to date suggest a third dose of our vaccine elicits antibody levels that significantly exceed those seen after the two-dose primary schedule. We are pleased to submit these data to the FDA as we continue working together to address the evolving challenges of this pandemic.”

“Vaccination is our most effective means of preventing COVID-19 infection – especially severe disease and hospitalization – and its profound impact on protecting lives is indisputable. Still, with the continuing threat of the Delta variant and possible emergence of other variants in the future, we must remain vigilant against this highly contagious virus,” said Albert Bourla, Chairman and Chief Executive Officer, Pfizer. “The data we’ve seen to date suggest a third dose of our vaccine elicits antibody levels that significantly exceed those seen after the two-dose primary schedule. We are pleased to submit these data to the FDA as we continue working together to address the evolving challenges of this pandemic.”

“We continuously strive to stay at least one step ahead of the virus. This is why we aim to expand access to our vaccine for people around the world and are working on various approaches as part of our comprehensive strategy to address the virus and its variants today as well as in the future,” said Ugur Sahin, M.D., CEO and Co-founder of BioNTech. “This initial data indicate that we may preserve and even exceed the high levels of protection against the wild-type virus and relevant variants using a third dose of our vaccine. A booster vaccine could help reduce infection and disease rates in people who have previously been vaccinated and better control the spread of virus variants during the coming season.”

Pfizer and BioNTech have submitted Phase 1 data – part of their Phase 1/2/3 clinical trial program – evaluating the safety, tolerability, and immunogenicity of a third dose of the COVID-19 vaccine in U.S. adult participants from the Phase 1 trial of the two-dose series. Participants received a 30-µg booster dose of BNT162b2 8 to 9 months after receiving the second dose. Results from this participant group show that the third dose elicited significantly higher neutralizing antibodies against the initial SARS-CoV-2 virus (wild type) compared to the levels observed after the two-dose primary series, as well as against the Beta variant and the highly infectious Delta variant.

Phase 3 results evaluating the third dose are expected shortly and will be submitted to the FDA, the EMA and other regulatory authorities worldwide. In the U.S., Pfizer and BioNTech plan to seek licensure of the third dose via a supplemental Biologics License Application (BLA) in individuals 16 years of age and older, pending FDA approval of the primary BLA submitted in May 2021.

A third dose of the Pfizer-BioNTech vaccine is not currently authorized for broad use in the U.S. However, under the current amended Emergency Use Authorization, a third dose was authorized on August 12 for administration to individuals at least 12 years of age who have undergone solid organ transplantation, or who are diagnosed with conditions that are considered to have an equivalent level of immunocompromise. This authorization is based on information from an independent report evaluating safety and effectiveness of a third dose in people who received solid organ transplants.

The Pfizer-BioNTech COVID-19 Vaccine, which is based on BioNTech proprietary mRNA technology, was developed by both BioNTech and Pfizer. BioNTech is the Marketing Authorization Holder in the European Union, and the holder of emergency use authorizations or equivalent in the United States (jointly with Pfizer), Canada and other countries. Submissions to pursue regulatory approvals in those countries where emergency use authorizations or equivalent were initially granted are ongoing or planned.

The Pfizer-BioNTech COVID-19 Vaccine has not been approved or licensed by the U.S. Food and Drug Administration (FDA), but has been authorized for emergency use by FDA under an Emergency Use Authorization (EUA) to prevent Coronavirus Disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) for use in individuals 12 years of age and older. The emergency use of this product is only authorized for the duration of the declaration that circumstances exist justifying the authorization of emergency use of the medical product under Section 564 (b) (1) of the FD&C Act unless the declaration is terminated or authorization revoked sooner.

AUTHORIZED USE IN THE U.S.:

The Pfizer-BioNTech COVID19 Vaccine is authorized for use under an Emergency Use Authorization (EUA) for active immunization to prevent coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in individuals 12 years of age and older.

  • Additional adverse reactions, some of which may be serious, may become apparent with more widespread use of the Pfizer-BioNTech COVID-19 Vaccine
  • Available data on Pfizer-BioNTech COVID-19 Vaccine administered to pregnant women are insufficient to inform vaccine-associated risks in pregnancy
  • Data are not available to assess the effects of Pfizer-BioNTech COVID-19 Vaccine on the breastfed infant or on milk production/excretion
  • There are no data available on the interchangeability of the Pfizer-BioNTech COVID-19 Vaccine with other COVID-19 vaccines to complete the vaccination series.

This year will be a doozy in terms of drugs going off-patent – undoubtedly a point of contention that will be discussed at length at next week’s J.P. Morgan Healthcare Conference. Dickson Data put together an excellent infographic that illustrates the various drugs that will be prey for generics makers this year. Drugs aimed at mitigating heart disease will be most impacted: AstraZeneca cholesterol drug Crestor will be the biggest big pharma blow, as it brings in some $6.4 billion in annual revenue. Other major hits will be Daiichi Sankyo’s high blood pressure drug Benicor and Merck’s cholesterol drug Zetia.

Novartis' Sandoz spotlights importance of generic drugs in new social campaign

Novartis | December 17, 2020

Did you realize that 90% of remedies are composed for nonexclusive medications? Novartis' Sandoz is getting the news out about nonexclusive medication with such realities in its as of late dispatched "Request Generics" crusade. It's Sandoz's first significant instruction and mindfulness crusade via online media to advance the estimation of generics. The intended interest group is key partners—patients, clinicians, policymakers and payers—with messages running on LinkedIn and Twitter. Sandoz plans to run the mission through the finish of the principal quarter, perhaps more, contingent upon results. It's as of now chipping away at a second stage that will move center to biosimilar adaptations of marked biologic medications. "Generics are assuming a truly significant job, and I believe it's ideal planning currently to discuss the significant job generics play in a well-working medical care framework," said Carol Lynch, Sandoz's U.S. president and head of North America. Other than featuring the pervasiveness of generics, the online media posts promote their reasonableness and their status as firmly directed items—as protected and powerful as their image name partners. The moderateness and security messages are significant, alongside the general token of the opposition generics give in the commercial center. The duplicates of costlier marked medications help to make "a sound serious market that is directed to patients having expanded admittance to the prescriptions they need," Lynch said. Nonexclusive medications saved the U.S. medical services framework $313 billion a year ago, as per the 2020 yearly report of conventional and biosimilar access and reserve funds in the U.S. from the Association for Accessible Medicines, a generics industry exchange gathering.
