"As we continue to execute on our Phase 3 trials for domvanalimab in lung and GI cancers, we have one of three important near-term data readouts now behind us. Today’s presentation of data from our Phase 2 EDGE-Gastric study provided important evidence to support domvanalimab’s potential as a differentiated and first-to-market anti-TIGIT antibody for the treatment of first-line upper GI adenocarcinomas. We are also looking forward to sharing more on our HIF-2a inhibitor, AB521, which continues to show a potentially improved clinical profile, with PK/PD results in patients consistent with those seen in healthy volunteers," said Terry Rosen, Ph.D., chief executive officer of Arcus. "Lastly, we will be presenting mature OS data from our Phase 1/1b study of quemliclustat in pancreatic cancer early next year; we are excited to share next steps in the coming months."

Pipeline Highlights:

Domvanalimab (Fc-silent anti-TIGIT monoclonal antibody)
•Preliminary data from Arm A1 of the Phase 2 EDGE-Gastric study, evaluating domvanalimab plus zimberelimab and chemotherapy in patients with previously untreated, locally advanced unresectable or metastatic upper gastrointestinal (GI) cancers, were presented during the Annual Meeting of the American Society of Clinical Oncology (ASCO) (Free ASCO Whitepaper) Plenary Series on November 7, 2023. These data were from the cohort that includes a patient population and dosing regimen similar to the ongoing Phase 3 study, STAR-221.
◦Domvanalimab plus zimberelimab and chemotherapy showed encouraging objective response rates (ORR) of 80% (confirmed ORR (cORR) of 73%) in patients with PD-L1-high tumors (TAP ≥5%), 46% (all confirmed) in patients with PD-L1-low tumors (TAP <5%) and 59% (cORR of 56%) for patients overall.
◦Six-month landmark progression-free survival (PFS) was 93% for patients with PD-L1-high tumors (TAP ≥5%), 68% for patients with PD-L1-low tumors (TAP <5%) and 77% for patients overall.
◦Mature PFS has not been reached and data are expected in the second half of 2024.
◦Domvanalimab plus zimberelimab and chemotherapy was well tolerated, with a similar safety profile to what has been reported for anti-PD-1 plus chemotherapy in this setting.

◦Domvanalimab is the only Fc-silent anti-TIGIT antibody in Phase 3 for gastric, gastroesophageal junction and esophageal adenocarcinoma and has the potential to be first to market for these cancers. These tumor types represent a potential drug-treatable population of over 25,000 in the US and over 100,000 in G-7 countries.
AB521 (HIF-2a inhibitor)

•Pharmacokinetic (PK) and pharmacodynamic (PD) data from the dose-escalation phase of ARC-20, a Phase 1/1b study of AB521 in cancer patients, are consistent with the results seen in healthy volunteers to date.
◦No dose-limiting toxicities have been observed to date in ARC-20.
◦Detailed PK, PD and safety data along with preliminary anti-tumor activity from this stage of ARC-20 will be shared in early 2024.
•Enrollment for the dose-expansion stage of ARC-20 in clear cell renal cell carcinoma (ccRCC) patients is near completion. Efficacy data from this stage of the ARC-20 study are expected later in 2024. The dose-expansion stage will include 30 patients on a 100-mg daily dose, which Arcus believes has the potential to achieve substantially greaterHIF-2a inhibition than the approved dose of the marketed competitor.
•A Phase 2 study evaluating AB521 in combination with a tyrosine kinase inhibitor (TKI) is anticipated to begin in the fourth quarter of 2023.
Quemliclustat (small-molecule CD73 inhibitor)
•Arcus conducted an analysis of mature OS data (minimum follow-up of 18 months) from the ongoing Phase 1/1b ARC-8 trial evaluating quemliclustat plus chemotherapy with or without zimberelimab in first-line pancreatic cancer.
◦At this analysis, 122 patients in the study had received the go-forward dose of 100 mg of quemliclustat; median follow-up time was 21 months.
◦These data will be presented in early 2024.
Etrumadenant (A2a/A2b adenosine receptor antagonist)
•Data from ARC-9, a Phase 1b/2 study evaluating etrumadenant plus zimberelimab plus chemotherapy in second-line and third-line metastatic colorectal cancer (mCRC), which is fully enrolled, are expected in the first half of 2024.
Early Clinical and Preclinical Programs
•ARC-25, a Phase 1 trial in cancer patients for AB598, an anti-CD39 antibody, is currently enrolling.
•Arcus initiated a Phase 1 study in healthy volunteers of AB801, its potent and highly selective AXL inhibitor, and expects to initiate a Phase 1 study in advanced cancer patients in the first quarter of 2024.
•Arcus expects to select a new development candidate against KIT, a target involved in multiple allergic and immune-mediated diseases, by year end.
Financial Results for Third Quarter 2023:
•Cash, Cash Equivalents and Marketable Securities were $950 million as of September 30, 2023, compared to $1.1 billion as of December 31, 2022. The decrease during the period is primarily due to the use of cash in research and development activities, partially offset by receipts of $35 million in upfront payments from Gilead to initiate Arcus-led discovery and early development activities on two jointly selected inflammation targets and $25 million in proceeds from the issuance of 1.2 million shares of our common stock. Arcus now expects cash utilization between $265 million and $290 million for the year ended December 31, 2023. Arcus continues to expect cash, cash equivalents and marketable securities on-hand to be sufficient to fund operations into 2026.
•Revenues were $32 million for the third quarter 2023, compared to $33 million for the same period in 2022. In the third quarter 2023, Arcus recognized $22 million in license and development service revenues related to the advancement of programs, primarily the Gilead collaboration, as well as $10 million in other collaboration revenue primarily related to Gilead’s ongoing rights to access Arcus’s research and development pipeline in accordance with the Gilead collaboration agreement. Revenues were $86 million for the nine months ended September 30, 2023, compared to $78 million for the same period in 2022.
•Research and Development (R&D) Expenses were $82 million for the third quarter 2023, compared to $77 million for the same period in 2022. The net increase of $5 million was primarily driven by: $7 million of higher spend for Arcus programs not under a cost-sharing collaboration due to our expanding clinical and development activities; partially offset by a net decrease of $2 million in shared costs for programs optioned by our collaboration partners, primarily from the Gilead collaboration. The net decrease of $2 million was due to a decrease in shared collaboration costs of $10 million primarily from the timing of clinical manufacturing; with a corresponding decrease in reimbursements for shared expenses of $8 million. Non-cash stock-based compensation expense was $8 million for each of the third quarter 2023 and 2022. R&D expenses were $247 million for the nine months ended September 30, 2023, compared to $208 million for the same period in 2022. For third quarter 2023 and 2022, Arcus recognized reimbursements of $33 million and $41 million, respectively, for shared expenses from its collaborations, primarily the Gilead collaboration. Reimbursements were $119 million for the nine months ended September 30, 2023, compared to $111 million for the same period in 2022. R&D expense by quarter may fluctuate due to the timing of clinical manufacturing and standard-of-care therapeutic purchases with a corresponding impact on reimbursements.
•General and Administrative (G&A) Expenses were $30 million for the third quarter 2023, compared to $26 million for the same period in 2022. The increase was primarily driven by the increased complexity of supporting Arcus’s expanding clinical pipeline and partnership obligations. Non-cash stock-based compensation expense was $10 million for the third quarter 2023, compared to $8 million for the same period in 2022. G&A expenses were $88 million for the nine months ended September 30, 2023, compared to $76 million for the same period in 2022.
•Net Loss was $71 million for the third quarter 2023, compared to $65 million for the same period in 2022. The increase in net loss included an increase of $2 million in income tax expense primarily due to an increase in taxable income compared to the prior year. Net loss was $226 million for the nine months ended September 30, 2023, compared to $200 million for the same period in 2022.

"We are looking forward to our upcoming data presentations at the American Association for the Study of Liver Diseases (AASLD) – The Liver Meeting 2023, specifically the preliminary data from the Phase 2a clinical trial, AB-729-202, evaluating imdusiran, our RNAi therapeutic, in combination with VTP-300 and a nucleos(t)ide analogue in patients with chronic hepatitis B virus," said William Collier, President and Chief Executive Officer of Arbutus Biopharma. "These data have the potential to support our hypothesis that a functional cure for cHBV can be achieved by reducing surface antigen, suppressing HBV DNA and boosting the immune system. We continue to explore imdusiran as a cornerstone therapy as we dose patients in the additional treatment arm of the AB-729-202 trial that adds a low dose of nivolumab (Opdivo), an anti-PD-1 monoclonal antibody, to the triple combination, as well as continuing to dose and follow patients in the on-going AB-729-201 clinical trial combining imdusiran with short durations of Peg-IFNα-2a and ongoing NA therapy. In addition, we have dosed our first group of healthy subjects in our Phase 1a/1b clinical trial with AB-101 and are on-track to report data from the first part of this trial in the first half of 2024. We look forward to sharing additional updates on our progress in the coming months."

Mr. Collier, continued, "Following our recent pipeline optimization, we made the difficult decision to reduce our workforce as we continue to manage our operating expenses. I’d like to thank our departing employees for their dedication and valuable contributions towards our mission. The Company remains committed to continuing discovery research in chronic HBV."

Pipeline Updates and Key Milestones

Imdusiran (AB-729, RNAi Therapeutic)

Arbutus will be presenting preliminary data at AASLD from the first group of patients in its Phase 2a clinical trial (AB-729-202) that is evaluating imdusiran, nucleos(t)ide analogue (NA) therapy and Barinthus Bio’s (formerly Vaccitech plc) VTP-300, an HBV antigen-specific immunotherapy.

Enrollment is ongoing in the expanded cohort of the AB-729-202 clinical trial that is designed to enroll 20 patients who will receive imdusiran (60mg every 8 weeks) plus NA therapy for 24 weeks followed by VTP-300 plus up to two doses of low-dose nivolumab. Preliminary data from this additional treatment arm are expected in 2024.
Follow-up is continuing in the Company’s on-going Phase 2a clinical trial (AB-729-201), evaluating the safety, tolerability and antiviral activity of the combination of imdusiran and pegylated interferon alfa-2a (IFN) in patients with cHBV. Preliminary data presented at the EASL Congress in June 2023 suggest that the addition of IFN to imdusiran was generally well tolerated and appears to result in continued HBsAg declines in some patients. Arbutus plans to provide updates from this clinical trial in 2024.
AB-101 (Oral PD-L1 Inhibitor)

In September, the Company dosed the first subject in its Phase 1a/1b double-blind, randomized, placebo-controlled, clinical trial (AB-101-001) designed to investigate the safety, tolerability, pharmacokinetics (PK), and pharmacodynamics (PD) of single and multiple oral doses of AB-101 for up to 28 days in healthy subjects and patients with cHBV. The trial will be conducted in three parts starting with single ascending doses in healthy subjects, followed by multiple ascending doses in healthy subjects and culminating with multiple doses in patients with cHBV. Safety and PK/PD assessments will be performed prior to dose escalation in all trial parts. Initial data from part one of the trial are expected in the first half of 2024.
Corporate Updates

In connection with the Company’s decision in September to focus its pipeline on its HBV clinical stage compounds and discontinue its research programs, Arbutus has taken steps to streamline its organization and has reduced its workforce by 24%, effective November 6, 2023, primarily affecting its research function. As a result, Arbutus will incur a one-time restructuring charge of approximately $1.1 million that will be recorded in the fourth quarter of 2023.

With the organizational changes announced today and its ongoing cost management efforts, the Company now expects its current cash, cash equivalents and investments will be sufficient to fund its operations into the first quarter of 2026. The Company remains committed to continuing discovery research in chronic HBV.

In a separate press release issued today, Arbutus announced that William Collier will be retiring as President and CEO, as well as a member of the Company’s Board of Directors, at the end of 2023 and Michael J. McElhaugh, Arbutus Co-founder and COO, will serve as interim CEO and will join the Company’s Board of Directors.

The above corporate updates do not affect the Company’s pending litigations. Arbutus will continue 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 and Pfizer/BioNTech’s COVID-19 vaccines would not have been successful. Document production is currently on-going in the lawsuit against Moderna with the claim construction hearing scheduled for February 7, 2024. Document and written discovery in the lawsuit against Pfizer/BioNTech is ongoing and a date for a claim construction hearing has not been set.

Financial Results

Cash, Cash Equivalents and Investments

As of September 30, 2023, we had cash, cash equivalents and investments in marketable securities of $144.7 million compared to $184.3 million as of December 31, 2022. During the nine months ended September 30, 2023, we used $68.6 million in operating activities, which was partially offset by $26.0 million of net proceeds from the issuance of common shares under our "at-the-market" offering program. We expect our 2023 net cash burn to range from between $90 to $95 million, excluding any proceeds received from our "at the market program". We believe our cash runway will be sufficient to fund our operations into the first quarter of 2026.

Revenue

Total revenue was $4.7 million for the three months ended September 30, 2023, compared to $6.0 million for the same period in 2022. The decrease of $1.3 million was due primarily to a decrease in royalty revenue because of a decrease in Alnylam’s sales of ONPATTRO.

Operating Expenses

Research and development expenses were $20.2 million for the three months ended September 30, 2023 compared to $20.1 million for the same period in 2022. A decrease in expenses for drug supply manufacturing for our imdusiran Phase 2a clinical trials and expenses for our AB-836 Phase 1a/1b clinical trial, which was discontinued in the fourth quarter of 2022, were offset by an increase in expenses for our ongoing AB-101 clinical trial and our coronavirus program, which was discontinued in the third quarter of 2023. General and administrative expenses were $5.8 million for the three months ended September 30, 2023, compared to $3.5 million for the same period in 2022. This increase was due primarily to increases in employee-related costs, including non-cash stock-based compensation expense, and professional fees.

Net Loss

For the three months ended September 30, 2023, our net loss was $20.1 million, or a loss of $0.12 per basic and diluted common share, as compared to a net loss of $17.6 million, or a loss of $0.12 per basic and diluted common share, for the three months ended September 30, 2022.

Outstanding Shares

As of September 30, 2023, we had approximately 167.7 million common shares issued and outstanding, as well as approximately 21.0 million stock options and unvested restricted stock units outstanding. Roivant Sciences Ltd. owned approximately 23% of our outstanding common shares as of September 30, 2023.

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. We have identified compounds in our internal PD-L1 portfolio that could also be used in oncology indications.

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 290 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.

"We’ve made significant clinical advancements in our late-stage immuno-neurology programs in the second half of 2023," said Arnon Rosenthal, Ph.D., Chief Executive Officer of Alector. "Notably, we successfully completed enrollment in the INVOKE-2 Phase 2 trial in collaboration with AbbVie, positioning us for a meaningful data readout in the fourth quarter of 2024. In collaboration with GSK, we achieved our enrollment target of 103 symptomatic participants with frontotemporal dementia due to a progranulin gene mutation in the pivotal INFRONT-3 Phase 3 clinical trial of latozinemab. Further, we are progressing our strategic partnership with GSK to evaluate the potential of our progranulin programs in more prevalent neurodegenerative diseases with patient screening underway for the upcoming Phase 2 trial of AL101/GSK4257226 in early Alzheimer’s disease."

Gary Romano, M.D., Ph.D., Chief Medical Officer of Alector added, "Our TREM2 and progranulin programs represent significant opportunities to harness the brain’s innate immune system to treat these neurodegenerative diseases. To enhance the understanding of our novel programs, we will be hosting two events in December with renowned scientific and clinical experts who will provide greater insights into the potential of these programs."

Recent Clinical Updates

Immuno-Neurology Portfolio
Progranulin Programs (latozinemab (AL001) and AL101/GSK4527226) Being Developed in Collaboration with GSK

In October 2023, Alector completed enrollment of 103 symptomatic and 16 at-risk participants with frontotemporal dementia due to a progranulin gene mutation (FTD-GRN) in the pivotal, randomized, double-blind, placebo-controlled INFRONT-3 Phase 3 clinical trial of latozinemab for a treatment duration of 96 weeks. Enrollment completion is subject to revised protocol approval in countries outside the United States.
Earlier this year, Alector and GSK held a Type C meeting with the U.S. Food and Drug Administration (FDA) and received scientific advice from the European Medicines Agency (EMA) regarding INFRONT-3. The companies aligned with the FDA and EMA to conduct the primary analysis on symptomatic participants, supporting an enrollment target of approximately 90-100 symptomatic participants in INFRONT-3.
In the fourth quarter, GSK commenced patient screening in a global Phase 2 clinical trial with AL101/GSK4527226 in early Alzheimer’s disease (AD). Like Latozinemab, AL101 elevates progranulin (PGRN) levels and has a different PK/PD profile.
In September, at the 2023 Annual Meeting of the American College of Clinical Pharmacology (ACCP), Alector and GSK presented a poster on PK/PD modeling of PGRN elevation in blood and CSF based on a Phase 1 clinical trial of AL101.
TREM2 Program (AL002) Being Developed in Collaboration with AbbVie

In September 2023, Alector completed enrollment in the randomized, double-blind, placebo-controlled, dose-ranging, INVOKE-2 Phase 2 clinical trial, with data anticipated in the fourth quarter of 2024. The INVOKE-2 trial is designed to evaluate the efficacy and safety of AL002 in slowing disease progression in individuals with early AD. AL002 is a novel investigational humanized monoclonal antibody that binds to TREM2 to increase TREM2 signaling and the functionality of microglia. It is the most advanced TREM2 activating product candidate in clinical development worldwide.
Alector received payments totaling $12.5 million from AbbVie to support enrollment in the INVOKE-2 trial.

Third Quarter 2023 Financial Results

Revenue. Collaboration revenue for the quarter ended September 30, 2023, was $9.1 million, compared to $14.9 million for the same period in 2022. This decrease was primarily due to a $5.7 million decrease in collaboration revenue recognized for the AL101 programs, including a $4.6 million decrease in collaboration revenue due to an increase in total expected costs to satisfy the performance obligations for the AL101 AD program.

R&D Expenses. Total research and development expenses for the quarter ended September 30, 2023, were $46.3 million, compared to $48.3 million for the quarter ended September 30, 2022. The decrease of $2.0 million was mainly due to the Company’s strategy to prioritize late-stage programs.

G&A Expenses. Total general and administrative expenses for the quarter ended September 30, 2023, were $13.4 million, compared to $14.3 million for the same period in 2022. The decrease of $0.9 million was primarily due to a decrease in consulting expenses related to accounting, recruiting, IT, and other general expenses.

Net Loss. For the quarter ended September 30, 2023, Alector reported a net loss of $44.5 million, or $0.53 per share, compared to a net loss of $46.1 million, or $0.56 net loss per share, for the same period in 2022.
