"2023 was a productive year for Barinthus Bio, with data presented in our HBV and HPV programs, the first patient visit in our next generation prostate cancer program and up to $35 million of future funding committed from the Coalition for Epidemic Preparedness Innovations (CEPI) secured for our MERS program," said Bill Enright, Chief Executive Officer of Barinthus Bio. "We expect another data rich year in 2024, with anticipated final results from our Phase 1b/2 HPV APOLLO trial of VTP-200, and additional data from our two ongoing Phase 2 trials of VTP-300 in chronic HBV infection. In addition, our SNAP-TI platform is heading into the clinic for the first time as we expect to initiate a Phase 1 clinical trial of VTP-1000 in celiac disease, our lead program in autoimmunity."
2023 Corporate Milestones
Clinical Developments

HBV (VTP-300):
•In March 2023, we announced positive topline final data from the HBV002 Phase 2 clinical trial for VTP-300 in Chronic Hepatitis B (CHB). The data showed meaningful, durable reductions of Hepatitis B Surface Antigen (HBsAg) in all participants with a >0.5 log10 reduction in HBsAg who received VTP-300 alone or in combination with a single administration of low-dose PD-1 inhibitor, nivolumab. Two of five patients with baseline HBsAg below 100 IU/mL in Group 3, developed a non-detectable HBsAg level, which continued eight months after last dose. We presented the final data in June 2023 at the European Association for the Study of the Liver Congress 2023 – The International Liver CongressTM.
•In November 2023, we presented interim data from the HBV003 Phase 2b clinical trial for VTP-300 in CHB showing that VTP-300 in combination with nivolumab continued to show sustained HBsAg reductions, particularly in patients with HBsAg levels below or equal to 200IU/mL at screening. We presented this data during an oral presentation at the American Association for the Study of Liver Diseases (AASLD) – The Liver Meeting 2023.
•Also in November 2023, interim data from the Phase 2a AB-729-202 clinical trial in collaboration with Arbutus Biopharma Corporation (Arbutus) in CHB patients were presented at AASLD, showing that imdusiran in combination with VTP-300 demonstrated meaningful and sustained declines in HBsAg levels.
HPV (VTP-200):
•In March 2023, we announced favorable topline interim data from the HPV001 Phase 1b/2 clinical trial of VTP-200 in high-risk HPV (hrHPV) infection.
•In April, we presented interim data from the VTP-200 APOLLO (HPV001) Phase 1b/2 clinical trial in hrHPV infection at the 35th Annual International Papillomavirus Conference. Immunological results showed VTP-200 induced high T cell responses to HPV antigens, and was generally well-tolerated with no product-related grade 3 unsolicited events and no product-related SAEs.
Celiac Disease (VTP-1000):
•In December 2023, we submitted an Australian ethics submission and regulatory notification to the Alfred Research Review Committee for the Phase 1 GLU001 study in Celiac disease.
Prostate Cancer (VTP-850):
•In June 2023, we announced the dosing of the first patient in the PCA001 Phase 1/2 clinical trial for VTP-850 in prostate cancer.
MERS (VTP-500):
•In December 2023, we announced an agreement with the Coalition for Epidemic Preparedness Innovations (CEPI) and the University of Oxford, aiming to fast-track the development of our vaccine candidate, VTP-500, for the prevention of Middle East Respiratory Syndrome. This agreement includes CEPI investing funding of up to $35 million to Barinthus Bio in addition to funds previously committed to the University of Oxford to develop and stockpile a ready reserve of VTP-500.

Key Operational Updates

•In January 2023, we announced the appointment of Nadège Pelletier, Ph.D., as Chief Scientific Officer.
•In June 2023, we completed the move of our U.S. facility to Germantown, Maryland, which houses a state-of-the art wet laboratory and office space.
•In November 2023, we announced the company’s renaming as Barinthus Biotherapeutics plc to represent the evolution and expansion of its focus beyond vaccines. As part of the renaming, the Company changed its Nasdaq ticker to "BRNS", which became effective on Nasdaq on November 7, 2023.

A total of five late stage cancer patients have been enrolled based on the Bayesian Optimal Interval (BOIN) design of the trial in the first dosing cohort. To date, no dose-limiting toxicities (DLTs) have been reported among the 5 patients. Tumor shrinkage based on CT scan was observed in one heavily pre-treated patient (7 prior lines of therapy).

"Introducing the first anti-CD24 program for late stage cancer patients in the U.S. is a very important milestone for Antennova. We are especially grateful to the participation in the study by our patients and study centers, and encouraged to observe early clinical activity in this heavily pre-treated patient population based on clinical evaluation and translational data. We are working closely with study sites and investigators at MD Anderson, the University of California, San Francisco, the University of Colorado, and Yale University Cancer Center and look forward to providing periodic updates and presentations at major international medical conferences throughout the study." commented by Jay Mei, M.D., Ph. D., Founder and Chairman of the Board.

The PERFORM trial is a first-in-human, multi-center, open-label, Phase I dose-finding/escalation study of ATN-031 in patients with advanced solid tumors or B-NHL. The study’s primary objective is to evaluate the safety and tolerability of ATN-031 as a monotherapy, and determine the appropriate dose for Phase II studies. The secondary objective is to characterize the pharmacology, evaluate the immunogenicity, and assess the preliminary efficacy of ATN-031.

About ATN-031

ATN-031 is a first-in-class humanized anti-CD24 monoclonal antibody which inhibits the "don’t eat me" signal while stimulating the "eat me" signal, and enhances macrophage-mediated phagocytosis of cancer cells. Tumor cells evade the surveillance of the human immune system by over-expressing "don’t eat me" surface proteins that signal macrophages to prevent the detection and phagocytosis of cancer cells. CD24 is a prominent "don’t eat me" signal that plays a significant role in tumor immune evasion by suppressing macrophage-mediated phagocytosis. Compared to CD47, another "don’t eat me" target, CD24, has a more markedly restricted distribution in normal tissues and higher expression in cancerous tissues, especially solid tumors. Importantly, CD24 is differentiated from CD47 because it is not expressed on human red blood cells, allowing for a wider therapeutic window and minimal on-target-off-tumor toxicity.

CD24 acts as a novel innate immune checkpoint, orchestrating immune evasion through its interaction with the inhibitory receptor Siglec-10 (sialic-acid-binding Ig-like lectin 10), expressed on tumor-associated macrophages (TAMs). Preclinical data presented at the American Association for Cancer Research (AACR) (Free AACR Whitepaper) Annual Meeting in 2023 (AACR 2023) and the Society for Immunotherapy in Cancer Annual Meeting in 2022 (SITC 2022) demonstrated that ATN-031 can specifically bind to CD24 with nM affinity and block the interaction of CD24 and Siglec-10. Furthermore, ATN-31 induces efficient phagocytosis with a picomolar EC50 and stimulates the pro-inflammatory cytokines production by macrophages.
