Pfizer Inc. and BioNTech SE have announced that the U.S. Food and Drug Administration’s (FDA) Vaccines and Related Biological Products Advisory Committee (VRBPAC) voted 17 to 4 in support of the FDA granting Emergency Use Authorization (EUA) for the companies’ COVID-19 mRNA vaccine (BNT162b2). There is one member of the Committee whose vote is not included in the 17 to 4 vote decision.

VRBPAC based its recommendation on the totality of scientific evidence shared by the companies, including data from a pivotal Phase 3 clinical study announced last month and published today in The New England Journal of Medicine. The Phase 3 data demonstrated a vaccine efficacy rate of 95% in participants without prior SARS-CoV-2 infection (first primary objective) and also in participants with and without prior SARS-CoV-2 infection (second primary objective), in each case measured from 7 days after the second dose. The Data Monitoring Committee for the study has not reported any serious safety concerns related to the vaccine. Efficacy was consistent across age, gender, race and ethnicity demographics. All trial participants will continue to be monitored for an additional two years after their second dose to assess long-term protection and safety. The FDA will take the advisory committee’s recommendation into consideration when it makes a final determination.

“We have been looking forward to presenting our robust data package to the committee of vaccine experts for the U.S. government since we began our efforts to develop a novel COVID-19 vaccine earlier this year,” said Dr. Albert Bourla, Pfizer Chairman and CEO. “We are pleased with the committee’s strong majority vote, and if the FDA issues an authorization, stand at the ready to bring this vaccine to people in the U.S. in an effort to help combat this devastating pandemic.”

“I would like to thank the FDA’s advisory committee for recognizing the critical role that our vaccine may play in helping to address this ongoing pandemic. Today’s positive discussion and vote reinforces the potential of our COVID-19 vaccine candidate in helping to protect people against this deadly and devastating disease,” said Ugur Sahin, CEO and Co-founder of BioNTech.

FDA Advisory Committees provide non-binding recommendations, with the final decision on approval or authorization to be made by the FDA. Under an EUA, the FDA has the authority to allow unapproved medical products or unapproved uses of approved medical products to be used in an emergency to diagnose, treat, or prevent serious or life-threatening diseases or conditions during a declared public health emergency when there are no adequate, approved, and available alternatives.

About the Phase 2/3 Study

The ongoing Phase 3 clinical trial of BNT162b2, which is based on BioNTech’s proprietary mRNA technology, has enrolled more than 44,000 participants, the vast majority of whom have received their second dose. A breakdown of the diversity of clinical trial participants can be found here from more than 150 clinical trials sites in the U.S., Germany, Turkey, South Africa, Brazil and Argentina.

The Phase 3 trial is designed as a 1:1 vaccine candidate to placebo, randomized, observer-blinded study to obtain safety, immune response, and efficacy data needed for regulatory review. The trial’s primary endpoints are prevention of COVID-19 in those who have not been infected by SARS-CoV-2 prior to immunization, and prevention of COVID-19 regardless of whether participants have previously been infected by SARS-CoV-2. Secondary endpoints include prevention of severe COVID-19 in those groups. The study also will explore prevention of infection by SARS-CoV-2, the virus that causes COVID-19.

Data from this study, including longer term safety, comprehensive information on duration of protection, efficacy against asymptomatic SARS-CoV-2 infection, and safety and immunogenicity in adolescents 12 to 17 years of age will be gathered in the months ahead. Additional studies are planned to evaluate BNT162b2 in pregnant women, children younger than 12 years, and those in special risk groups, such as the immunocompromised.

A library is generated by synthesis with a chemical reactor system or by computer-based modeling of compound combinations. When undertaking combinatorial chemistry consider reagents, buffers, resins and standards.Data AnalysisData analysis hardware and software is available to make data processing straight-forward yet powerful. Data software can be used for math and stats, technical graphing and image analysis. In addition, software is available for specific data analysis of electrophoresis, densitometry, ELISA and DNA sequencing.ImmunologyImmunological techniques measure and characterize immune responses. Immunology kits and analysis systems often use techniques such as ELISA, radioimmunoassay (RIA) and immunodiffusion assays, Immunohistochemistry, and flow cytometry. Immunologists use equipment such as flow Cytometers, plate readers, plate washers and fluorescent microscopes.Cellular PathologyCellular Pathology deals with the microscopic analysis of tissue samples and cells. Sample preparation and processing includes fixation, staining, sectioning and slide mounting, using equipment such microtomes and cryostats. In choosing immunohistochemistry and immunocytochemistry kits, consider chromogens, staining method, antibodies, microscopes and imaging.Biopharmaceutical AdvancesBiopharmaceutical advances follow the development of pharmaceuticals derived from biotechnology, also known as biotechnology medicines. Biopharmaceuticals may be produced from cell lines, plants, or microbial cells. Important considerations of biopharmaceutical use include application, cost, production process and purification.Clinical TrialsClinical Trials, an essential part of drug discovery process, assess the safety and effectiveness of a new medication or device in the pharmaceutical industry. Clinical Trials are a phased process (Phase 0, Phase I, Phase II, Phase III and Phase IV) which begins after initial preclinical testing.Clinical ChemistryBiochemistry (or clinical chemistry) involves the analysis of bodily fluids using chemical tests. Techniques used include HPLC, chromatography, spectroscopy, mass spectrometry, immunochemical, electrophoresis, turbidometric / spectrophotometric assay, MRI and ISE analysis. Tests are often carried out on plasma or serum but urine (urinalysis) and fecal specimens are also processed.Clinical GeneticsMolecular Genetics covers the analysis of hereditary genetic disease and chromosomal abnormalities. Genetics can be analysed using DNA, RNA, and protein microarrays, PCR, RT PCR and DNA sequencing. Genetic equipment includes genetic workstations, thermal cyclers, cooling blocks and electrophoresis products. Diagnostic kits are used for DNA / RNA extraction and purification.Clinical MicrobiologyMicrobiology is the study of microorganisms including protists, prokaryotes, fungi, and, often, viruses. Microorganisms are a useful research tool as genetic vectors and, in immunology, for antibiotic susceptibility testing, cellular biology and genetics. Microorganisms commonly grow readily in incubators with microbial culture media; this can contain chromogenic supplements to differentiate between cell lines. Estimate your culture’s density of microorganisms with colony counters, or screen and select colonies for desirable clones with automated colony pickers.

Drug delivery is often approached via the biopharmaceutical or small molecule drug's formulation, but it may also involve medical devices or drug-device combination products. Considerations include instrumentation, software and services. RegulatoryPharmaceutical regulations impact on all areas of drug development, manufacture and control and supply. Services are provided from the early stages of drug development and clinical trials through to dossier submission, approval and marketing. Regulatory also includes submission of analytical studies from the pharmaceutical product and safety.
