Pfizer and BioNTech Complete Submission to European Medicines Agency for Omicron BA.4/BA.5 Adapted Bivalent Vaccine

• Submission follows application for Omicron BA.1-adapted bivalent vaccine submitted in July
• If authorized, both Omicron BA.1-adapted and Omicron BA.4/5-adapted bivalent vaccines will be available in the European Union as early as September

NEW YORK and MAINZ, GERMANY, August 26, 2022 — Pfizer Inc. (NYSE: PFE) and BioNTech SE (Nasdaq: BNTX) today announced they have completed a submission to the European Medicines Agency (EMA) for a booster dose of an Omicron BA.4/BA.5-adapted bivalent COVID-19 vaccine for individuals 12 years of age and older. This application for a variation of the conditional marketing authorization (cMA) follows guidance from the EMA and International Coalition of Medicines Regulatory Authorities (ICMRA) to work towards introducing Omicron-adapted bivalent vaccines.

The bivalent vaccine contains 15-µg of mRNA encoding the wild-type spike-protein of SARS-CoV-2, which is present in COMIRNATY^® (the original Pfizer-BioNTech COVID-19 Vaccine) and 15-µg of mRNA encoding the spike protein of the Omicron BA.4/BA.5 variants. With the exception of the addition to the mRNA of the Omicron BA.4/BA.5 spike protein sequence, all other components of the vaccine remain unchanged. Pre-clinical data showed a booster dose of Pfizer and BioNTech’s Omicron BA.4/BA.5-adapted bivalent vaccine generated a strong neutralizing antibody response against Omicron BA.1, BA.2 and BA.4/BA.5 variants, as well as the original wild-type strain. 

In addition to the pre-clinical, quality and manufacturing data for the Omicron BA.4/BA.5 adapted bivalent vaccine, the submission is supported by safety, tolerability and immunogenicity data from a Phase 2/3 trial of a 30-µg booster dose of their Omicron BA.1-adapted bivalent vaccine, which combines 15-µg of mRNA encoding the wild-type spike protein of SARS-CoV-2 with 15-µg of mRNA encoding the spike protein of the Omicron BA.1 variant. The companies have also provided safety data from clinical trials evaluating multiple variant-adapted vaccine candidates based on previous variants of concern (e.g., Alpha, Beta and Delta variants).

Pfizer and BioNTech also filed an application with the EMA for the Omicron BA.1-adapted bivalent COVID-19 vaccine in July which is currently under review by the Agency. Both the Omicron BA.1-adapted and Omicron BA.4/BA.5-adapted bivalent boosters will be available to ship shortly after respective regulatory authorizations and be available for use as early as September, pending regulatory approval. Local supply may vary based on individual country government requests.

On August 22, the companies also completed a submission to the U.S. Food and Drug Administration (FDA) requesting Emergency Use Authorization (EUA) of a booster dose of an Omicron BA.4/BA.5-adapted bivalent COVID-19 vaccine for individuals 12 years of age and older.

The Pfizer-BioNTech COVID-19 Vaccine, which is based on BioNTech’s proprietary mRNA technology, was developed by both BioNTech and Pfizer. BioNTech is the Marketing Authorization Holder for BNT162b2 (COMIRNATY^®) in the United States, the European Union, the United Kingdom, Canada and other countries, and the holder of emergency use authorizations or equivalents in the United States (jointly with Pfizer) and other countries. Submissions to pursue regulatory approvals in those countries where emergency use authorizations or equivalent were initially granted are planned.

AUTHORIZED USE IN THE EU:
COMIRNATY® ▼ (the Pfizer-BioNTech COVID-19 vaccine) has been granted conditional marketing authorization (CMA) by the European Commission to prevent coronavirus disease 2019 (COVID-19) in people aged 5 years and older. The vaccine is administered as a 2-dose series, 3 weeks apart. Adults and adolescents from the age of 12 are given 30 micrograms per dose; children aged 5 to 11 years are given 10 micrograms per dose. In addition, the CMA has been expanded to include a booster dose (third dose) at least 3 months after the second dose in individuals 12 years of age and older. A third primary course dose may be administered at least 28 days after the second dose to people aged 5 years and older with a severely weakened immune system. The European Medicines Agency’s (EMA’s) human medicines committee (CHMP) has completed its rigorous evaluation of COMIRNATY®, concluding by consensus that sufficiently robust data on the quality, safety and efficacy of the vaccine are now available.

IMPORTANT SAFETY INFORMATION:

• Events of anaphylaxis have been reported. Appropriate medical treatment and supervision should always be readily available in case of an anaphylactic reaction following the administration of the vaccine.
• There is an increased, but very rare risk (<1/10,000 cases) of myocarditis and pericarditis following vaccination with COMIRNATY. These conditions can develop within just a few days after vaccination, and have primarily occurred within 14 days. They have been observed more often after the second vaccination, and more often in younger males. Available data suggest that the course of myocarditis and pericarditis following vaccination is not different from myocarditis or pericarditis in general. The risk of myocarditis after a third dose of COMIRNATY has not yet been characterized.
• Rare cases of acute peripheral facial paralysis; uncommon incidence of insomnia, hyperhidrosis and night sweats; and unknown incidence of paraesthesia, hypoaesthesia and erythema multiforme have been identified in post-marketing experience.
• Anxiety-related reactions, including vasovagal reactions (syncope), hyperventilation or stress‐related reactions (e. g. dizziness, palpitations, increases in heart rate, alterations in blood pressure, tingling sensations and sweating) may occur in association with the vaccination process itself. Stress-related reactions are temporary and resolve on their own. Individuals should be advised to bring symptoms to the attention of the vaccination provider for evaluation. It is important that precautions are in place to avoid injury from fainting.
• Vaccination should be postponed in individuals suffering from acute severe febrile illness or acute infection. The presence of a minor infection and/or low-grade fever should not delay vaccination.
• As with other intramuscular injections, the vaccine should be given with caution in individuals receiving anticoagulant therapy or those with thrombocytopenia or any coagulation disorder (such as haemophilia) because bleeding or bruising may occur following an intramuscular administration in these individuals.
• The efficacy, safety and immunogenicity of the vaccine has not been assessed in immunocompromised individuals, including those receiving immunosuppressant therapy. The efficacy of COMIRNATY may be lower in immunosuppressed individuals.
• As with any vaccine, vaccination with COMIRNATY may not protect all vaccine recipients. Individuals may not be fully protected until 7 days after their second dose of vaccine.
• In clinical studies, adverse reactions in participants 16 years of age and older that received two doses were injection site pain (> 80%), fatigue (> 60%), headache (> 50%), myalgia and chills (> 30%), arthralgia (> 20%), pyrexia and injection site swelling (> 10%) and were usually mild or moderate in intensity and resolved within a few days after vaccination. A slightly lower frequency of reactogenicity events was associated with greater age.
• The overall safety profile of COMIRNATY in participants 5 to 15 years of age that received two doses was similar to that seen in participants 16 years of age and older. The most frequent adverse reactions in children 5 to 11 years of age were injection site pain (>80%), fatigue (>50%), headache (>30%), injection site redness and swelling (>20%), myalgia and chills (>10%).
• A large amount of observational data from pregnant women vaccinated with COMIRNATY during the second and third trimester have not shown an increase in adverse pregnancy outcomes. While data on pregnancy outcomes following vaccination during the first trimester are presently limited, no increased risk for miscarriage has been seen. COMIRNATY can be used during pregnancy. No effects on the breast-fed newborn/infant are anticipated since the systemic exposure of breast-feeding woman to COMIRNATY is negligible. Observational data from women who were breast-feeding after vaccination have not shown a risk for adverse effects in breast-fed newborns/infants. COMIRNATY can be used during breast-feeding.
• Interactions with other medicinal products or concomitant administration of COMIRNATY with other vaccines has not been studied.
• Animal studies do not indicate direct or indirect harmful effects with respect to reproductive toxicity.
• For complete information on the safety of COMIRNATY, always make reference to the approved Summary of Product Characteristics and Package Leaflet available in all the languages of the European Union on the EMA website.
