VTP-850

Significantly greater mean declines in HBsAg levels (p <0.017) were seen in those receiving imdusiran, VTP-300 and low-dose nivolumab compared to other cohorts assessed previously 23% of participants receiving imdusiran, VTP-300 and low-dose nivolumab reached HBsAg loss by Week 48 WARMINSTER, Pa. and OXFORD, United Kingdom, Nov. 15, 2024 (GLOBE NEWSWIRE) -- Arbutus Biopharma Corporation (Nasdaq: ABUS), (“Arbutus” or the “Company”) a clinical-stage biopharmaceutical company leveraging its extensive virology expertise to develop a functional cure for people with chronic hepatitis B virus infection, and Barinthus Biotherapeutics plc (NASDAQ: BRNS), a clinical-stage biopharmaceutical company developing novel immunotherapeutic candidates that guide T cells to control disease, today announced new preliminary data from the Phase 2a IM-PROVE II clinical trial (AB-729-202) of people with chronic hepatitis B virus (cHBV) at the American Association for the Study of Liver Diseases (AASLD) – The Liver Meeting® 2024. The new data are from an additional cohort of participants (Group C) who received repeat doses of imdusiran, Arbutus’ RNAi therapeutic, followed by Barinthus Bio's T-cell stimulating immunotherapeutic, VTP-300, with or without low-dose nivolumab, an anti-PD-1 monoclonal antibody. The data indicated that Group C participants receiving nivolumab experienced increased rates of HBsAg loss (defined as HBsAg 0.5 log10 decline in HBsAg between Weeks 26 and 34). This trial was amended to include an additional cohort (Group C) which enrolled 22 participants, 13 of which were eligible to receive imdusiran (60mg every 8 weeks) for 24 weeks with ongoing NUC therapy followed by VTP-300 at Weeks 26 and 30 plus up to two low doses of nivolumab (0.3 mg/kg), an approved PD-1 monoclonal antibody at Week 30. The remaining 9 participants received the imdusiran/NUC/VTP-300 regimen without nivolumab. Participants could receive a second dose of VTP-300 ± low-dose nivolumab at Week 38 if their HBsAg was ≥10 IU/mL at Week 34. Upon completion of the treatment period at Week 48, all participants who met certain criteria could discontinue NUC therapy and be followed for an additional 48 weeks. Those who did not meet the criteria continued on NUC therapy for an additional 24 weeks of follow-up. About Imdusiran (AB-729) Imdusiran is an RNA interference (RNAi) therapeutic specifically designed to reduce all HBV viral proteins and antigens including hepatitis B surface antigen, which is thought to be a key prerequisite to enable reawakening of a patient’s immune system to respond to the virus. Imdusiran targets hepatocytes using Arbutus’ novel covalently conjugated N-Acetylgalactosamine (GalNAc) delivery technology enabling subcutaneous delivery. Clinical data generated thus far has shown single and multiple doses of imdusiran to be generally safe and well-tolerated, while also providing meaningful reductions in hepatitis B surface antigen and hepatitis B DNA. Imdusiran is currently in multiple Phase 2a clinical trials. About VTP-300 VTP-300 is an immunotherapeutic candidate consisting of an initial dose using the ChAdOx vector and a secondary dose(s) using the MVA vector, both encoding multiple HBsAg, 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 Bio 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 infection. About Arbutus Arbutus Biopharma Corporation (Nasdaq: ABUS) is a clinical-stage biopharmaceutical company leveraging its extensive virology expertise to develop novel therapeutics with distinct mechanisms of action, which can potentially be combined to provide a functional cure for patients with chronic hepatitis B virus (cHBV). Arbutus believes the key to success in developing a functional cure involves suppressing HBV DNA, reducing surface antigen, and boosting HBV-specific immune responses. Arbutus’ pipeline of internally developed, proprietary compounds includes an RNAi therapeutic, imdusiran (AB-729), and an oral PD-L1 inhibitor, AB-101. Imdusiran has generated meaningful clinical data demonstrating an impact on both surface antigen reduction and reawakening of the HBV-specific immune response. Imdusiran is currently in two Phase 2a combination clinical trials. AB-101 is currently being evaluated in a Phase 1a/1b clinical trial. For more information, visit www.arbutusbio.com.

OXFORD, United Kingdom, Nov. 06, 2024 (GLOBE NEWSWIRE) -- Barinthus Biotherapeutics plc (NASDAQ: BRNS), a clinical-stage biopharmaceutical company developing novel immunotherapeutic candidates that guide T cells to control disease, provided an overview of business updates and announced financial results for the third quarter of 2024. “We continue our strong execution on our clinical trials, completing enrollment in the HBV003 trial of VTP-300 in chronic hepatitis B, and advancing VTP-1000 in celiac disease into the clinic with the first in human study of the novel SNAP-TI platform,” said Dr. Leon Hooftman, Chief Medical Officer of Barinthus Bio. “We expect a data rich fourth quarter from the VTP-300 chronic hepatitis B program, with updated interim readouts from both the HBV003 and IM-PROVE II trials accepted as late-breaking abstracts at the American Association for the Study of Liver Diseases (AASLD) – The Liver Meeting® 2024. These updates will provide more mature data than previously disclosed as participants progress and move towards a potential functional cure.” Third Quarter 2024 and Recent Corporate Developments VTP-300 (Chronic hepatitis B) In September 2024, enrollment was completed in the HBV003 trial of VTP-300 in 121 adult participants with chronic hepatitis B. The Phase 2b trial is designed to obtain critical dosing information for a potential functional cure regimen for chronic hepatitis B, with participants receiving VTP-300 and low-dose (LD) nivolumab. Earlier this year, interim data from the HBV003 trial was presented at the European Association for the Study of the Liver (EASL) Congress and demonstrated that treatment with VTP-300 and LD nivolumab was generally well-tolerated and led to a sustained decline in Hepatitis B surface antigen (HBsAg) levels. Seventy-six percent of participants (n=16/21) assessed for nucleos(t)ide analogue (NUC) therapy discontinuation met the criteria. Sixty-seven percent of participants (n=14/21) assessed for NUC discontinuation had HBsAg <10 IU/mL at Week 24 or later. Nineteen percent of the eligible participants (n=4/21) reached undetectable levels of HBsAg, with 2 of these patients maintaining undetectable levels for over 16 weeks. VTP-1000 (Celiac Disease) In September 2024, we initiated the first-in-human Phase 1 AVALON trial of VTP-1000 in adults with celiac disease. The randomized, placebo-controlled clinical trial, which includes a controlled gluten challenge, will evaluate the safety, tolerability, pharmacokinetics and pharmacodynamics of VTP-1000. VTP-850 (Prostate Cancer) In October 2024, we announced that the PCA001 trial of VTP-850 in men with rising prostate-specific antigen (PSA) after definitive local therapy for prostate cancer (i.e., biochemical recurrence) had completed patient enrollment of 22 participants. The Phase 1 trial is designed to evaluate safety and efficacy, as measured by PSA and T cell response. We expect to have data from the Phase 1 trial in the first half of 2025. Financial Update In October 2024, we were informed that an additional $15.0 million of revenue was due to the Company from Oxford University Innovation (OUI) in relation to the Company's share of royalties received by OUI, as a result of prior commercial sales of Vaxzevria® by AstraZeneca. We expect that this additional cash, when received, will enable us to fund our research and development plans further into the second quarter of 2026. Upcoming Milestones VTP-300 (Chronic hepatitis B) In the fourth quarter of 2024, we expect to announce updated data from the VTP-300 program in ongoing clinical trials in chronic hepatitis B at AASLD – The Liver Meeting® 2024 scheduled from November 15-19, 2024 in San Diego, CA: Updated interim data from HBV003, the Phase 2b trial evaluating additional dosing of VTP-300 and timing of PD-1 inhibition, accepted as a late-breaking oral presentation.Updated interim data from the Phase 2a IM-PROVE II clinical trial evaluating the combination of VTP-300 and Arbutus Biopharma’s imdusiran, accepted as a late-breaking poster. VTP-1000 (Celiac Disease) In the first half of 2025, we expect to announce data from the single ascending dose part of the Phase 1 AVALON trial of VTP-1000 in adults with celiac disease. VTP-850 (Prostate Cancer) In the first half of 2025, we expect to announce results of the Phase 1 PCA001 trial of VTP-850 in men with rising PSA after definitive local therapy for prostate cancer (i.e., biochemical recurrence). Third Quarter 2024 Financial Highlights Cash position: As of September 30, 2024, cash, cash equivalents and restricted cash were $106.1 million, compared to $117.8 million as of June 30, 2024. The net cash used in operating activities was $18.2 million in the third quarter of 2024, primarily resulting from the development of our pipeline and ongoing clinical trials, offset by $6.2 million due to the effect of foreign exchange rates on cash balances. Based on our current operating plans, we expect our available resources to fund operating expenses and capital expenditure requirements into the second quarter of 2026.Revenue: Revenue consisted of $15.0 million in the third quarter of 2024 compared to nil in the second quarter of 2024. Revenue was comprised of the Company’s share of royalties received by OUI as a result of prior commercial sales of Vaxzevria® by AstraZeneca.There is no expectation of additional payments or that we will be notified of such payments in a timely manner.Research and development expenses: Research and development expenses were $11.1 million in the third quarter of 2024 compared to $11.7 million in the second quarter of 2024, with the decrease mainly attributable to a reduction in personnel-related costs as a result of the pipeline prioritization earlier in the year. The quarter-on-quarter R&D expense per program is outlined in the following table.
