Pfizer, BioNTech plan emergency move to use Covid-19 vaccine
NEW DELHI: Pfizer and BioNTech SE (Nasdaq: BNTX) announced they will submit a request today to the U.S. Food and Drug Administration (FDA) for Emergency Use Authorization (EUA) of their mRNA vaccine candidate, BNT162b2 against SARS-CoV-2, which will potentially enable use of the vaccine in high-risk populations in the U.S. by the middle to end of December 2020.
The submission is based on a vaccine efficacy rate of 95% (p<0>
The first primary objective analysis was based on 170 confirmed cases of COVID-19. This submission also is supported by solicited safety data from a randomized subset of approximately 8,000 participants ?18 years of age and unsolicited safety data from approximately 38,000 trial participants who have been followed for a median of two months following the second dose of the vaccine candidate. The submission also includes solicited safety data on approximately 100 children 12-15 years of age.
Approximately 42% of global participants and 30% of U.S. participants in the Phase 3 study have racially and ethnically diverse backgrounds, and 41% of global and 45% of U.S. participants are 56-85 years of age. To date, the Data Monitoring Committee (DMC) for the study has not reported any serious safety concerns related to the vaccine.
Our work to deliver a safe and effective vaccine has never been more urgent, as we continue to see an alarming rise in the number of cases of COVID-19 globally. Filing in the U.S. represents a critical milestone in our journey to deliver a COVID-19 vaccine to the world and we now have a more complete picture of both the efficacy and safety profile of our vaccine, giving us confidence in its potential, said Dr. Albert Bourla, Pfizer Chairman and CEO.
We look forward to the upcoming Vaccines and Related Biological Products Advisory Committee discussion and continue to work closely with the FDA and regulatory authorities worldwide to secure authorization of our vaccine candidate as quickly as possible,” Dr Bourla added.
Filing for Emergency Use Authorization in the U.S. is a critical step in making our vaccine candidate available to the global population as quickly as possible, said Ugur Sahin, M.D., CEO and Co-founder of BioNTech.
We intend to continue to work with regulatory agencies worldwide to enable the rapid distribution of our vaccine globally. As a company located in Germany in the heart of Europe, our interactions with the European Medicines Agency (EMA) are of particular importance to us and we have continuously provided data to them as part of our rolling review process,” Sahin added.
The companieshave already initiated rolling submissions with several regulatory agencies around the world, including the EMA and the Medicines & Healthcare Products Regulatory Agency (MHRA) in the United Kingdom, and intend to submit applications to other regulatory agencies worldwide in the coming days. In some cases, governments may have regulatory pathways similar to an EUA. The companies will be ready to distribute the vaccine candidate within hours after authorization.
Pfizer and BioNTech are extremely grateful to the study volunteers and investigative site staff in the clinical trial program, as their involvement was crucial to todays important milestone in the companies efforts to address the COVID-19 global pandemic.
The BNT162b2 vaccine candidate is not currently approved for distribution anywhere in the world. Both collaborators are committed to developing this novel vaccine with preclinical and clinical data at the forefront of all their decision making.
Manufacturing and Delivery Capabilities
While Pfizer and BioNTech await potential authorization or approval from regulatory agencies, the companies continue to work in collaboration with governments and Ministries of Health around the world that will distribute the vaccine, subject to authorization or approval, to help ensure it can reach those most in need as quickly as possible.
Pfizer is bringing its leading in-house manufacturing capabilities to this effort, with the ability and experience to quickly scale, manufacture and distribute large quantities of vaccine at high quality, leveraging multiple sites in the U.S. and Europe, and complementing the mRNA manufacturing expertise of BioNTech, gained over almost a decade. Pfizer and BioNTechs combined manufacturing network has the potential to supply up to 50 million vaccine doses globally in 2020 and up to 1.3 billion doses by the end of 2021 (subject to clinical success, manufacturing capacity, and regulatory approval or authorization).
Pfizer has vast experience and expertise in cold-chain shipping and has an established infrastructure to supply the vaccine worldwide, including distribution hubs that can store vaccine doses for up to six months. The company has developed specially designed, temperature-controlled shippers for the BNT162b2 vaccine candidate, which can maintain recommended storage conditions (-70°C ±10°C) up to 15 days. Each shipper contains a GPS-enabled thermal sensor to track the location and temperature of each vaccine shipment. Once thawed, the vaccine vial can be stored for up to 5 days at refrigerated (2 – 8oC) conditions.
From the start of the research program earlier this year, Pfizer and BioNTech have successfully supplied and distributed their investigational vaccine to more than 150 clinical trial sites across the U.S., as well as Europe, Latin America, and South Africa. Based on their collective experience, the companies believe in their capability to distribute the vaccine globally upon approval or authorization.
About the Study
The Phase 3 clinical trial of BNT162b2, which is based on BioNTech’s proprietary mRNA technology, began on July 27 and has enrolled 43,661 participants to date, 41,135 of whom have received a second dose of the vaccine candidate as of November 13, 2020. A breakdown of the diversity of clinical trial participants can be found here from approximately 150 clinical trials sites in the U.S., Germany, Turkey, South Africa, Brazil and Argentina. Participants will continue to be monitored for long-term protection and safety for an additional two years after their second dose.
Pfizer and BioNTech plan to submit the efficacy and safety data from the study for peer-review in a scientific journal once analysis of the data is completed.
