- The stock price of VBI Vaccines Inc. (Nasdaq: VBIV) increased by over 19% pre-market today. This is why it happened.
The stock price of VBI Vaccines Inc. (Nasdaq: VBIV) – a biopharmaceutical company driven by immunology in the pursuit of powerful prevention and treatment of disease – increased by over 19% pre-market today. Investors are responding positively to the company announcing that the U.S. Food and Drug Administration (FDA) has approved PreHevbrio [Hepatitis B Vaccine (Recombinant)] for the prevention of infection caused by all known subtypes of hepatitis B virus (HBV) in adults age 18 years and older. And PreHevbrio contains the S, pre-S2, and pre-S1 HBV surface antigens, and is the only approved 3-antigen HBV vaccine for adults in the U.S.
The approval of PreHevbrio was based on the results from two Phase 3 clinical studies, PROTECT and CONSTANT, data from which were published, respectively, in The Lancet Infectious Diseases in May 2021 and The Journal of the American Medical Association Network Open in October 2021. These pivotal studies compared PreHevbrio to Engerix-B, a single-antigen HBV vaccine.
The Data from the PROTECT study showed that PreHevbrio elicited higher rates of seroprotection in all subjects age 18+ (91.4% vs. 76.5%), including in adults age 45+ (89.4% vs. 73.1%). And the integrated safety analysis of both studies demonstrated good tolerability with no unexpected reactogenicity. The most common adverse events in all age groups were injection site pain and tenderness, myalgia, and fatigue, all which generally resolved without intervention in 1-2 days.
VBI plans to make PreHevbrio available in the U.S. in the first quarter of 2022, and has partnered with Syneos Health for the past 2 years to ensure commercial readiness.
Outside of the U.S., VBI continues to support the European Medicines Agency’s (EMA) ongoing review of the marketing authorization application for VBI’s 3-antigen HBV vaccine. And VBI expects to complete regulatory submissions to the United Kingdom’s Medicines and Healthcare products Regulatory Agency (MHRA) and to Health Canada in 2022.
“As we work to implement the ACIP’s new universal hepatitis B vaccine recommendation for all adults ages 19-59, as voted on in November, we benefit from having more tools, including this newly approved 3-antigen hepatitis B vaccine. Having more vaccine options will help us effectively expand vaccine uptake, ensure more people are protected from hepatitis B infection, and reach the 2030 goal of eliminating hepatitis B in the U.S.”
— Chari Cohen, DrPH, MPH, Senior Vice President of the Hepatitis B Foundation
“We are proud to announce the approval of PreHevbrio, VBI’s first FDA-approved vaccine. This is a substantial achievement that demonstrates the VBI team’s ability to progress vaccine candidates from the clinic through to approval. This approval, however, is just the first step in our mission to provide broad access to our vaccine and to help strengthen the public health effort to put an end to adult HBV infections. We would like to thank the study participants, clinical site investigators, our employees, and all who contributed to this achievement, and we look forward to working with public health and advocacy organizations as we join the fight against hepatitis B.”
— Jeff Baxter, VBI’s President and CEO
