• New Corporate Brand to be Unveiled at AASLD Liver Meeting® 2023 with Interim Data

OXFORD, United Kingdom, Nov. 06, 2023 (GLOBE NEWSWIRE) -- Barinthus Biotherapeutics plc (NASDAQ: BRNS), formerly Vaccitech plc (NASDAQ: VACC), a clinical-stage biopharmaceutical company developing novel T cell immunotherapeutic candidates designed to guide the immune system to overcome chronic infectious diseases, autoimmunity and cancer will present data from its Phase 2 Hepatitis B trials of VTP-300 at The American Association for the Study of Liver Diseases (AASLD) – The Liver Meeting® 2023, November 10-14 in Boston, MA.

The company also announced today that it has changed its name to Barinthus Biotherapeutics plc to represent the evolution and expansion of its focus beyond vaccines. The company expects to begin trading under its new name and ticker (Nasdaq: BRNS) effective as of November 7, 2023. As part of the rebranding, the company has also updated its website -- learn more at www.barinthusbio.com.

“The company has evolved and expanded since being spun out of the University of Oxford. Whereas we began as a vaccine company having been involved in flu vaccines and then the co-invention and early development of Vaxzevria, the AstraZeneca/Oxford COVID-19 vaccine and the development of other prophylactic vaccines,” said Bill Enright, Chief Executive Officer of Barinthus Biotherapeutics. “Today the company is focused on the development of novel T cell immunotherapeutic candidates, which evolved out of that initial vaccine research. We believe that guiding the capabilities of T cells using our proprietary platform technologies provides broader developmental opportunities with a huge potential to eventually impact patients’ lives. We are excited to continue into the next chapter of the company’s story – as Barinthus Biotherapeutics.”

The company’s new name takes inspiration from “Barinthus,” the mythological navigator who guided King Arthur of Britain by ship to the island of Avalon to be healed when he was wounded. The story of the legendary king being wounded and being guided to a place of healing where he continues to live is mirrored in our proprietary platforms and technology that are designed to guide the immune system to treat infectious diseases, autoimmunity, and cancer.

Abstract Number: 46173

Title: A Phase 2b, Open-Label Study to Evaluate the Efficacy, Safety, Tolerability, Immunogenicity and Treatment Regimens of VTP-300 Combined with Low-Dose Nivolumab (LDN) in Chronic Hepatitis B Infection.

Presentation Type: Oral Presentation

Session: Hepatitis B: New Therapies for HBV and HDV

Presentation Time: Sunday, November 12, 09:15 ET

Authors: Yuen MF, Chuang WL, Avihingsanon A, Lim S, Mukherjee D, Radka K, Bussey l, Evans T, Tait D

Data Summary: VTP-300 has previously demonstrated meaningful and durable HBsAg reductions in patients with HBV as a monotherapy and in combination with LDN in a Phase 1b/2a study. Evaluating repeat dosing of Modified Vaccinia Ankara (MVA)-HBV and the timing of PD-1 inhibitor administration in patients with chronic Hepatitis B is an important piece to optimizing the regimen of VTP-300, which may be a critical component of a functional cure regimen.

Both presentations will be available on Barinthus Biotherapeutics’ website following their release at AASLD.

About VTP-300

VTP-300 is an investigational immunotherapeutic candidate consisting of an initial dose using the ChAdOx platform and a secondary dose(s) using MVA, both encoding multiple Hepatitis B antigens, including full-length surface, modified polymerase, and core antigens. VTP-300 is the first antigen-specific immunotherapy that has been shown to induce sustained reductions in HBsAg. Barinthus Biotherapeutics is studying VTP-300 in combination with other agents, including siRNA and low-dose anti-PD-1 antibodies, to control the infection and counterbalance the immune suppression and T cell exhaustion in the liver caused by chronic HBV.

About Hepatitis B Virus (HBV)

Globally it is estimated that there are more than 300 million people, including up to 2.4 million in the U.S. and 14 million in Europe, living with chronic HBV infection, with the highest prevalence in East Asia and Africa. Approximately 820,000 people die each year from HBV and related complications, such as liver cirrhosis and hepatocellular carcinoma. Due to low HBV diagnosis rates of about 10.5% aware of their infection coupled with strict treatment eligibility guidelines, only 6.6 million (2.2%) people with chronic HBV are receiving treatment and less than 10% will achieve a functional cure with existing therapies.
