The company's prioritization of imdusiran's Phase 2b development, based on promising clinical data, represents a calculated bet on this asset's potential. While this focus could accelerate the path to a potential functional HBV cure, it also increases the company's dependence on imdusiran's success.
Investors should closely monitor the upcoming imdusiran Phase 2b trial and AB-101 data expected in H2 2024, as these will be critical in assessing Arbutus's future prospects and the wisdom of their strategic shift.
The clinical data presented for imdusiran at the EASL Congress is particularly intriguing. In the IM-PROVE I trial,
The IM-PROVE II trial, combining imdusiran with VTP-300, also showed promise. Statistically significant differences in HBsAg levels between treatment and placebo arms were observed 24 weeks post-treatment. This hints at the potential of combination therapies in achieving more durable responses.
However, it's important to note that these are Phase 2a trials with relatively small patient numbers. The upcoming Phase 2b trial will be important in confirming these results in a larger population and determining the optimal treatment regimen.
The decision to terminate the IM-PROVE III trial (combining imdusiran with durvalumab) before dosing any participants is somewhat disappointing from a scientific perspective, as it could have provided valuable insights into the role of PD-L1 inhibition in HBV treatment. However, given resource constraints, focusing on the most promising avenues is understandable.
The preliminary data from the AB-101 trial, showing dose-dependent receptor occupancy, is encouraging but early. The multiple-ascending dose data expected later this year will be important in assessing this oral PD-L1 inhibitor's potential.
The ongoing litigation against Moderna and Pfizer/BioNTech regarding Arbutus's LNP technology patents is a significant aspect of the company's potential future value. The trial date set for April 21, 2025, in the Moderna case provides a concrete timeline for potential resolution. However, it's important to note that trial dates are subject to change and patent litigation can be protracted and unpredictable.
Arbutus's stance that it's seeking "fair compensation" for the use of its patented LNP technology in COVID-19 vaccines suggests the company believes it has a strong case. If successful, this could result in substantial royalties or a settlement, potentially transforming Arbutus's financial position.
However, the lack of a set date for a claim construction hearing in the Pfizer/BioNTech case indicates this litigation may be progressing more slowly. Investors should be aware that patent litigation outcomes are never guaranteed and even if Arbutus prevails, the appeals process could further delay any financial benefits.
The company's commitment to "protect and defend its intellectual property" is commendable from a shareholder perspective, but also carries risks. Patent litigation is expensive and time-consuming, potentially diverting resources from core R&D activities. The
While a favorable outcome could be transformative for Arbutus, investors should view this as a potential upside rather than a certainty and focus primarily on the company's clinical progress in evaluating its prospects.

WARMINSTER, Pa., Aug. 01, 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 (cHBV) infection, today reports second quarter 2024 financial results and provides a corporate update.
“At the EASL Congress we reported impressive imdusiran data. I’m particularly excited that in the IM-PROVE I clinical trial we saw undetectable HBsAg in
Mr. McElhaugh continued, “We intend to focus our existing resources on conducting a Phase 2b clinical trial with imdusiran, assuming continued positive data. This has the potential to create a true inflection point for both Arbutus and HBV patients. To ensure we have the resources to conduct such a program, we have made the difficult decision to discontinue our HBV research efforts and reduce our headcount leading to a projected cash runway into the fourth quarter of 2026. I want to express my sincere gratitude to those impacted by the workforce reduction for their invaluable contributions to our mission and their dedication to helping HBV patients.”
Clinical Development Update
Imdusiran (AB-729, RNAi Therapeutic)
- At the EASL Congress in June, end-of-treatment data was presented from IM-PROVE I (AB-729-201), a Phase 2a clinical trial evaluating the safety, tolerability and antiviral activity of the combination of imdusiran, nucleos(t)ide analogue (NA) therapy and pegylated interferon alfa-2a (IFN) in patients with cHBV. The data showed that
33.3% (n=4/12) of patients in Cohort A1 receiving 48 weeks of imdusiran combined with a short course of IFN (24-weeks) and NA therapy, achieved undetectable HBsAg at the end-of-treatment that was maintained in100% of these patients 24 weeks after completing imdusiran and IFN treatment. Undetectable HBsAg was achieved in67% of those patients with HBsAg less than 1000 IU/mL at baseline. A total of six patients who received 24 weeks of IFN (n=4 Cohort A1; n=2 Cohort A2) seroconverted, with HBsAg loss accompanied by high titers of anti-HBsAg antibodies. All six of these patients have stopped NA therapy, with two of those patients reaching 12 weeks off all therapy with sustained undetectable levels of HBsAg and HBV DNA. The combination of imdusiran and IFN in this clinical trial was generally safe and well-tolerated. - Also at the EASL Congress in June, end-of treatment data was presented from the IM-PROVE II (AB-729-202) Phase 2a clinical trial evaluating the safety and immunogenicity of imdusiran, NA therapy and Barinthus Bio’s VTP-300, an HBV antigen-specific immunotherapy. The data showed that at 24-weeks post-end of treatment with imdusiran and VTP-300, statistical significance (p<0.05) was achieved in HBsAg levels between the treatment arm (n=5) and placebo (n=6). In addition, more patients maintained HBsAg thresholds of <100 IU/mL and <10 IU/mL when administered VTP-300 vs. placebo at 24-weeks post end-of-treatment. The combination of imdusiran and VTP-300 in this clinical trial was generally safe and well-tolerated.
- IM-PROVE II includes an additional cohort of patients who will receive imdusiran plus NA therapy for 24 weeks followed by VTP-300 plus up to two low doses of nivolumab, an approved anti-PD-1 monoclonal antibody. Arbutus is on-track to report preliminary end-of-treatment data from this additional cohort in the second half of 2024.
- Arbutus has terminated its Phase 2a clinical trial evaluating the safety, tolerability and antiviral activity of imdusiran and NA therapy in combination with intermittent low doses of durvalumab, an approved anti-PD-L1 monoclonal antibody (IM-PROVE III, AB-729-203) prior to dosing any participants. This decision was based on a prioritization of resources and the projected availability of clinical data from this trial.
AB-101 (Oral PD-L1 Inhibitor)
- AB-101-001 is a Phase 1a/1b double-blind, randomized, placebo-controlled clinical trial designed to investigate the safety, tolerability, pharmacokinetics (PK), and pharmacodynamics (PD) of single- and multiple-ascending oral doses of AB-101 for up to 28 days in healthy subjects and patients with cHBV. Part 1 of the clinical trial has enrolled four sequential cohorts of eight healthy subjects each (6 active:2 placebo) to date, each receiving a single dose of AB-101 at increasing dose levels up to 25 mg or placebo. Data from Part 1 of this trial showed that AB-101 was generally well-tolerated with evidence of dose-dependent receptor occupancy. In the 25 mg cohort, all five evaluable subjects showed evidence of receptor occupancy between 50
-100% . Arbutus has moved into Part 2 of this clinical trial which evaluates multiple-ascending doses of AB-101 in healthy subjects and expects to report preliminary data in the second half of this year.
Corporate Updates
- The Company has made the decision to streamline the organization to focus its efforts on advancing the clinical development of imdusiran and AB-101, and is therefore ceasing all discovery efforts and discontinuing its IM-PROVE III clinical trial. In taking these steps to streamline the organization, Arbutus is implementing a reduction in its workforce of
40% , primarily affecting the discovery and general and administrative functions. As a result, Arbutus will incur a one-time restructuring charge of approximately$3.0 -$4.0 million that will be recorded in the third quarter of 2024. With these organizational changes and its ongoing cost management efforts, the Company now expects its current cash, cash equivalents and investments in marketable securities will be sufficient to fund operations into the fourth quarter of 2026.
LNP Litigation Update
- Next steps in the lawsuit against Moderna include expert reports and expert depositions. A trial date has been set for April 21, 2025, and is subject to change.
- The lawsuit against Pfizer/BioNTech is ongoing and a date for a claim construction hearing has not been set.
Arbutus continues to protect and defend its intellectual property, which is the subject of the on-going lawsuits against Moderna and Pfizer/BioNTech. The Company is seeking fair compensation for Moderna’s and Pfizer/BioNTech’s use of its patented LNP technology that was developed with great effort and at a great expense, without which Moderna’s and Pfizer/BioNTech’s COVID-19 vaccines would not have been successful.

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 AB-101
AB-101 is our oral PD-L1 inhibitor candidate that we believe will allow for controlled checkpoint blockade while minimizing the systemic safety issues typically seen with checkpoint antibody therapies. Immune checkpoints such as PD-1/PD-L1 play an important role in the induction and maintenance of immune tolerance and in T-cell activation. Preclinical data generated thus far indicates that AB-101 mediates re-activation of exhausted HBV-specific T-cells from cHBV patients. We believe AB-101, when used in combination with other approved and investigational agents, could potentially lead to a functional cure in patients chronically infected with HBV. AB-101 is currently being evaluated in a Phase 1a/1b clinical trial.
About HBV
Hepatitis B is a potentially life-threatening liver infection caused by the hepatitis B virus (HBV). HBV can cause chronic infection which leads to a higher risk of death from cirrhosis and liver cancer. Chronic HBV infection represents a significant unmet medical need. The World Health Organization estimates that over 250 million people worldwide suffer from chronic HBV infection, while other estimates indicate that approximately 2.4 million people in the United States suffer from chronic HBV infection. Approximately 820,000 people die every year from complications related to chronic HBV infection despite the availability of effective vaccines and current treatment options.
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). We believe the key to success in developing a functional cure involves suppressing HBV DNA, reducing surface antigen, and boosting HBV-specific immune responses. Our 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.
