Barinthus Biotherapeutics plc is a clinical-stage biopharmaceutical company that has been making significant strides in developing novel immunotherapeutic candidates designed to guide the immune system to overcome chronic infectious diseases and autoimmunity. With a focused pipeline built around proprietary platform technologies, the company has been making impressive progress in advancing its lead programs in hepatitis B and celiac disease.
Business Overview and Company History
Barinthus Biotherapeutics was founded in 2016 as a public limited company incorporated pursuant to the laws of England and Wales. Originally named Vaccitech plc, the company changed its name to Barinthus Biotherapeutics plc in November 2023. The company's vision has been to develop innovative T cell-based immunotherapies to address significant unmet medical needs.
In its early years, Barinthus Bio made significant investments in research and development, establishing and building its adenovirus platform, enhancing its in-licensed ChAdOx1, ChAdOx2 and MVA vectors, and developing a new next-generation adenoviral vector. The company also acquired new technology platforms, including SNAP, which has formed the foundation for its diverse pipeline alongside the ChAdOx platform.
A major milestone for the company came in March 2021 when it raised gross proceeds of £125.2 million from the issuance of its series B shares. This was quickly followed by its initial public offering on Nasdaq in May 2021, which raised an additional £110.5 million in gross proceeds. These substantial funding rounds provided Barinthus Bio with the capital needed to accelerate its research and development efforts and fuel the advancement of its clinical programs.
The company's journey has not been without challenges. While Barinthus Bio incurred net losses each year since inception through 2021, it managed to generate net income of £5.3 million in 2022, primarily from revenues related to prior commercial sales of Vaxzevria by AstraZeneca. However, the company then faced a net loss of £73.4 million in 2023. Additionally, Barinthus Bio has had to navigate the impact of global economic conditions, inflationary pressures, and volatility in financial markets, which have posed potential risks to its operations and financial condition.
Despite these challenges, Barinthus Bio has remained focused on advancing its pipeline. The company has made significant progress on several of its key programs, including VTP-300 for chronic hepatitis B and VTP-1000 for celiac disease. In 2024, Barinthus Bio achieved important milestones, including the completion of enrollment in the HBV003 trial of VTP-300 and the initiation of the first-in-human Phase 1 trial of VTP-1000.
Furthermore, the company received a PRIME designation from the European Medicines Agency (EMA) for VTP-500, its vaccine candidate against Middle East Respiratory Syndrome (MERS), highlighting the potential impact of its pipeline beyond its lead programs.
Financial Overview
Barinthus Biotherapeutics has reported mixed financial results in recent years. For the year ended December 31, 2023, the company reported a net loss of $73.4 million, compared to net income of $5.3 million in the previous year. This shift from profitability to a net loss was primarily due to increased research and development expenses as the company advanced its clinical pipeline.
For the most recent quarter ended September 30, 2024, Barinthus Bio reported revenue of $14,969,000, primarily from license revenue related to prior commercial sales of Vaxzevria by AstraZeneca. The company incurred a net loss of $8,114,000 during the quarter. Operating cash flow for the quarter was negative $13,878,000, while free cash flow was negative $11,433,000.
Liquidity
In terms of liquidity, as of September 30, 2024, Barinthus Bio had $106.1 million in cash, cash equivalents, and restricted cash. The company's cash position has been bolstered by various financing activities, including the $110.5 million raised in its 2021 IPO and additional capital raised through at-the-market offerings under its $200 million shelf registration.
The company's current ratio and quick ratio both stand at 8.93, indicating a strong short-term liquidity position. This healthy liquidity profile provides Barinthus Bio with the financial flexibility to continue advancing its clinical programs.
While the company's cash runway is expected to extend into the second quarter of 2026, Barinthus Bio has recently announced a strategic pipeline prioritization that is anticipated to result in a 25% reduction in its workforce and an extension of its cash runway. This move is aimed at ensuring the company's resources are allocated to the most promising programs, VTP-300 and VTP-1000, which have the greatest potential for success and value creation.
Pipeline and Clinical Progress
Barinthus Bio's pipeline is centered around its proprietary viral vector and synthetic platforms, with a focus on advancing immunotherapeutic candidates in the areas of chronic infectious diseases and autoimmunity. Following a strategic pipeline update in June 2024, the company is prioritizing a pipeline of two key product candidates:
VTP-300 for Chronic Hepatitis B
VTP-300, the company's lead candidate, is an investigational immunotherapy designed to be a potential component of a functional cure regimen for chronic hepatitis B virus (CHB) infection. The candidate utilizes the company's ChAdOx and MVA viral vector platforms and is being evaluated in two ongoing Phase 2 clinical trials, HBV003 and IM-PROVE II (in collaboration with Arbutus Biopharma).
The latest interim data from these trials, presented at the European Association for the Study of the Liver (EASL) Congress in June 2024, have been highly encouraging. In the HBV003 trial, 67% of participants had hepatitis B surface antigen (HBsAg) levels below 10 IU/mL, and 19% had undetectable HBsAg, which are important markers for functional cure. Additionally, 76% of participants were eligible for discontinuation of nucleos(t)ide analog (NUC) therapy. The IM-PROVE II trial also demonstrated a statistically significant difference in HBsAg levels between the VTP-300 treatment and placebo groups at 24 weeks post-end of treatment, with 84% of participants who received VTP-300 discontinuing standard of care NUC therapy, compared to 53% in the placebo group.
These promising results have led Barinthus Bio to prioritize the development of VTP-300, with plans to present updated data from the HBV003 and IM-PROVE II trials at the American Association for the Study of Liver Diseases (AASLD) – The Liver Meeting® 2024.
VTP-1000 for Celiac Disease
In September 2024, Barinthus Bio announced the initiation of a first-in-human Phase 1 clinical trial of VTP-1000, its investigational immunotherapy candidate for the treatment of celiac disease. The randomized, placebo-controlled trial, known as the AVALON study, is designed to evaluate the safety, tolerability, pharmacokinetics, and pharmacodynamics of VTP-1000 in adults with celiac disease, including a controlled gluten challenge.
Celiac disease is a chronic autoimmune disorder that affects an estimated one in 100 people globally, and for which there are currently no approved treatments. Barinthus Bio's VTP-1000 leverages its proprietary SNAP-TI platform to specifically target the underlying immune dysregulation that drives the disease, representing a potentially transformative approach to addressing this significant unmet medical need.
The initiation of the AVALON trial marks an important milestone for Barinthus Bio as it expands its pipeline into the autoimmunity space, building on the success of its viral vector-based programs in infectious diseases.
Additional Pipeline Programs
In addition to its two priority programs, Barinthus Bio has partnerships to advance three additional prophylactic and therapeutic product candidates:
1. VTP-500 for Middle East Respiratory Syndrome (MERS) 2. VTP-400 for Zoster 3. VTP-600 for multiple cancer indications including Non-Small Cell Lung Cancer and Squamous Esophageal Cancer
These partnerships demonstrate the versatility of Barinthus Bio's platform technologies and its potential to address a wide range of medical needs beyond its core focus areas.
