• Postponing further clinical development of VTP-300 in chronic hepatitis B (CHB) until a partner is identified
• Extending the cash runway to the start of 2027 by reducing costs, including an approximate 65% reduction in workforce and expected closure of the U.K. site
• Future operations will be focused at the U.S. site in Germantown, Maryland

OXFORD, United Kingdom and GERMANTOWN, Md., Jan. 10, 2025 (GLOBE NEWSWIRE) — Barinthus Biotherapeutics plc (NASDAQ: BRNS) (“Barinthus Bio,” or the “Company”), today provided a strategic business and financial update. Barinthus Bio is a clinical-stage biopharmaceutical company developing novel immunotherapeutic candidates that guide T cells to control disease.

Strategic Business Focus and Restructuring:

• The Company will prioritize I&I indications, including antigen-specific immune tolerance.
• The Company plans to extend the cash runway to the start of 2027 by reducing costs, including a reduction in headcount by approximately 65% across both sites, and streamlining the operating costs of the business.
• As part of the restructuring, two of the executive leadership team members based in the U.K., the Chief Operating Officer, Graham Griffiths, and Chief Financial Officer, Gemma Brown, will leave the Company. Further plans for the re-organized team will be communicated in due course.
• The Company will not invest in VTP-300 in chronic hepatitis B beyond the completion of the ongoing Phase 2b HBV003 clinical trial and will seek potential partners able to take advantage of its differentiated ability to achieve sustained HBsAg loss and functional cure in patients with low levels of HBsAg.

Financial Update:

• Cash, cash equivalents and restricted cash are expected to be $112 million as of December 31, 2024.¹
• Based on management’s current assumptions and taking into account expected cost savings from the corporate restructuring, the Company believes its available resources will fund its operations to the start of 2027.

Anticipated 2025 Corporate Milestones:
Celiac disease:

• Announcement of single ascending dose data from AVALON, the first-in-human Phase 1 clinical trial evaluating the safety, tolerability, pharmacokinetics and pharmacodynamics of VTP-1000 in adults with celiac disease expected in the middle of 2025.
• Initiation of multiple ascending dose portion of the Phase 1 clinical trial expected in the third quarter of 2025.

Chronic hepatitis B:

• Announcement of results from Phase 2b HBV003 clinical trial evaluating additional dosing of VTP-300 and low-dose nivolumab timing in people with chronic hepatitis B infection expected in the second quarter of 2025.
• Announcement of results from the Phase 2a IM-PROVE II clinical trial evaluating VTP-300, low-dose nivolumab and Arbutus’ imdusiran in people with chronic hepatitis B infection expected in the second quarter of 2025.

Prostate cancer:

• Announcement of results from Phase 1 PCA001 clinical trial evaluating safety and efficacy of VTP-850 in men with rising prostate-specific antigen (PSA) after definitive local therapy for prostate cancer (i.e., biochemical recurrence) expected in the second quarter of 2025.

“Entering 2025, we have decided to focus on broadening the potential of our SNAP-TI platform to address autoimmune diseases to enable us to maximize value for shareholders. We expect initial Phase 1 clinical data from VTP-1000 in celiac disease in mid-2025 and intend to develop further SNAP-TI products in other indications, both by ourselves and with partners,” said Bill Enright, Chief Executive Officer of Barinthus Bio. “Although we achieved the major goal of functional cure in a subset of patients with chronic hepatitis B (CHB) in recent interim readouts of the VTP-300 studies, we have decided to seek potential partners for furthering VTP-300 development, as we believe that this is the best route to leverage a combination of the technologies required and to get VTP-300 to patients as soon as possible. As a result of our shift in strategy, we have made the difficult decision to reduce our presence in the U.K. significantly and to reduce our workforce to align the business appropriately. I am immensely proud and grateful for what our team of talented employees has achieved and would like to thank them for their part in advancing Barinthus to where we are today, especially Gemma Brown and Graham Griffiths our CFO and COO, respectively. This team is one of the best I’ve had the pleasure to work with.”
