Well positioned financially with a projected cash runway into the second quarter of 2024

Conference Call and Webcast Today at 8:45 AM ET

WARMINSTER, Pa., May 05, 2022 (GLOBE NEWSWIRE) -- Arbutus Biopharma Corporation (Nasdaq: ABUS), a clinical-stage biopharmaceutical company leveraging its extensive virology expertise to develop novel therapeutics that target specific viral diseases, today reports its first quarter 2022 financial results and provides pipeline updates.

“In the first quarter of 2022, we continued to advance our efforts to develop a functional cure for hepatitis B and to develop novel treatment options for coronavirus infections, including SARS-CoV-2,” said William Collier, Arbutus’ President and Chief Executive Officer. “We are on-track to achieve our goal of reporting data later this year from four clinical trials with chronically infected HBV patients being treated with either AB-729, our RNAi therapeutic, or AB-836, our next generation oral capsid inhibitor. Furthermore, our IND-enabling studies with our oral PD-L1 inhibitor, AB-101, and our oral RNA destabilizer, AB-161, are moving forward and we expect these to be completed in the second half of 2022. Additionally, we have had seven abstracts accepted at the EASL International Liver Congress™, which include some of these data.”

Mr. Collier continued, “With respect to our research efforts to develop a nsp5 main protease (M^pro) and nsp12 viral polymerase for SARS-CoV-2 and future coronavirus outbreaks, we are on-track to initiate IND-enabling studies for a nsp5 M^pro candidate later this year. Lead optimization activities are continuing for a nsp12 viral polymerase candidate. Financially, we are well-positioned to continue advancing all our current clinical programs through important data milestones with a projected cash runway into the second quarter of 2024.”

Anticipated Milestones in 2022:

• Dose first patient in the AB-729-202 Phase 2a clinical trial evaluating AB-729, in combination with VTP-300, Vaccitech plc’s (Vaccitech) therapeutic vaccine and nucleos(t)ide analogue therapy (NA), in cHBV patients in the first half of 2022.  
• Present new on-treatment data as well as long-term off-treatment data for cHBV patients in the AB-729-001 clinical trial at a medical conference later this year.
• Report initial data from the AB-729-201 Phase 2a clinical trial evaluating AB-729 in combination with ongoing NA therapy and short courses of PEG-IFNα-2a in cHBV patients in the second half of 2022.
• Report initial data from the Phase 2a clinical trial evaluating AB-729 in combination with vebicorvir (VBR), Assembly Biosciences, Inc.’s (Assembly) lead HBV core inhibitor (capsid inhibitor), and an NA in cHBV patients in the second half of 2022.
• Report data set from the AB-836-001 clinical trial evaluating multiple doses of AB-836 in cHBV patients in the first half of 2022.
• Complete IND-enabling studies for two oral compounds (PD-L1 inhibitor, AB-101 and RNA destabilizer, AB-161) to treat HBV in the second half of 2022.
• Advance an oral compound that inhibits the SARS-CoV-2 nsp5 main protease into IND enabling studies in the second half of 2022.
• Continue to explore a potential oncology indication with our oral PD-L1 program.

Financial Results

Cash, Cash Equivalents and Investments

As of March 31, 2022, the Company had cash, cash equivalents and investments in marketable securities of $221.8 million, as compared to $191.0 million as of December 31, 2021.

During the three months ended March 31, 2022, the Company received a $40.0 million (net of withholding taxes) upfront payment from Qilu Pharmaceutical Co., Ltd. (“Qilu”) related to a technology transfer and license agreement for AB-729 in greater China, $15.0 million of gross proceeds from Qilu’s equity investment and $0.3 million of net proceeds from the issuance of common shares under Arbutus’s “at-the-market” offering program. These cash inflows were partially offset by $23.4 million of cash used in operations. The Company expects a net cash burn between $90 to $95 million in 2022, not including the $55 million of proceeds received from Qilu, and believes its cash runway will be sufficient to fund operations into the second quarter of 2024.

Revenue

Revenues were $12.6 million for the three months ended March 31, 2022 compared to $2.1 million for the same period in 2021. The increase of $10.5 million was due primarily to $9.6 million of revenue recognition from the Company’s license agreement with Qilu based on employee labor hours expended by the Company during the first quarter of 2022 to perform its manufacturing obligations under the license agreement.
  
Net Loss

For the three months ended March 31, 2022, the Company’s net loss attributable to common shares was $15.8 million, or a loss of $0.11 per basic and diluted common share, as compared to a net loss attributable to common shares of $19.6 million, or a loss of $0.21 per basic and diluted common share, for the three months ended March 31, 2021. Net loss attributable to common shares for the three months ended March 31, 2021 included $3.2 million of non-cash expense for the accrual coupon on the Company’s convertible preferred shares, which converted into 22.8 million common shares in October 2021.

Operating Expenses

Research and development expenses were $18.5 million for the three months ended March 31, 2022 compared to $13.8 million for the same period in 2021. The increase of $4.7 million was due primarily to an increase in expenses related to the Company’s multiple, ongoing AB-729 Phase 2a clinical trials, including its collaborations with Assembly and Vaccitech, an increase in expenses for its ongoing AB-836-001 clinical trial, and an increase in expenses for its early stage development programs, including AB-101 and AB-161. General and administrative expenses were $4.9 million for the three months ended March 31, 2022 compared to $3.9 million for the same period in 2021. This increase was due primarily to increases in professional fees, employee compensation and non-cash stock-based compensation expense.

Outstanding Shares

As of March 31, 2022, the Company had approximately 148.7 million common shares issued and outstanding, as well as approximately 15.7 million stock options outstanding. Roivant Sciences Ltd. owned approximately 26% of the Company’s outstanding common shares as of March 31, 2022.

COVID-19 Impact 

The COVID-19 pandemic has resulted in and will likely continue to result in significant disruptions to businesses. Measures implemented around the world in attempts to slow the spread of COVID-19 have had, and will likely continue to have, a major impact on clinical development, at least in the near-term, including shortages and delays in the supply chain and prohibitions in certain countries on enrolling subjects and patients in new clinical trials. While we have been able to progress with our clinical and pre-clinical activities to date, it is not possible to predict if the COVID-19 pandemic will materially impact our plans and timelines in the future.

About AB-729 

AB-729 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. AB-729 targets hepatocytes using Arbutus’ novel covalently conjugated N-acetylgalactosamine (GalNAc) delivery technology that enables subcutaneous delivery. Clinical data generated thus far has shown single- and multi-doses of AB-729 to be generally safe and well-tolerated while providing meaningful reductions in hepatitis B surface antigen and hepatitis B DNA. AB-729 is currently in multiple Phase 2a clinical trials.  

About AB-836 

AB-836 is a next generation oral hepatitis B virus (HBV) capsid inhibitor that interacts with HBV core protein, which in turn is required for viral replication. The current standard-of-care therapy for HBV is primarily nucleos(t)ide analogues that inhibit the viral polymerase and significantly reduce, but do not eliminate viral replication. AB-836 in combination with nucleos(t)ide analogues is designed to completely eliminate viral replication in infected cells by preventing the assembly of functional viral capsids. In addition, AB-836 has been shown to inhibit the replenishment of covalently closed circular DNA (cccDNA), the viral genetic reservoir which the virus needs to replicate itself. Preliminary data from an on-going Phase 1a/1b clinical trial has shown that AB-836 is generally safe and well-tolerated and provides robust antiviral activity. 

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. 

About Arbutus 

Arbutus Biopharma Corporation (Nasdaq: ABUS) is a clinical-stage biopharmaceutical company leveraging its extensive virology expertise to develop novel therapeutics that target specific viral diseases. Our current focus areas include Hepatitis B virus (HBV), SARS-CoV-2, and other coronaviruses. In HBV, we are developing an RNAi therapeutic, oral capsid inhibitor, oral PD-L1 inhibitor, and oral RNA destabilizer that we intend to combine to provide a functional cure for patients with chronic HBV by suppressing viral replication, reducing surface antigen and reawakening the immune system. We believe our lead compound, AB-729, is the only RNAi therapeutic with evidence of immune re-awakening, and is currently being evaluated in multiple phase 2 clinical trials. We have an ongoing drug discovery and development program directed to identifying novel, orally active agents for treating coronavirus (including SARS-CoV-2). We are also exploring oncology applications for our internal PD-L1 portfolio.  For more information, visit www.arbutusbio.com.
